Top 8 Kentucky Caves to Tour

Universal Stopping Point Photography/Getty Images

We all know Kentucky's horse farms and hills are stunning sights, but have you explored what lies beneath these picturesque landscapes? You may not realize it, but Kentucky is home to an extensive system of caves, some of which may be toured. Cave exploring, also known as spelunking, is an ideal activity for science buffs and history aficionados alike.

Mammoth Cave

The world's longest surveyed cave system, Mammoth Cave contains 400 miles of explored passageways, with more being discovered each year. Mammoth Cave National Park provides tours covering more than 10 miles of the system. Most tours cover 1 to 2 miles. Along with its immense length, Mammoth Cave houses clues to how the cave has been used by humans for thousands of years.

Lost River Cave

Feel like going on an underground boat tour? Well, this is one spot you can do it. In addition to exploring this 7-mile cave system—including having to lower your head to enter an enormous cave—there are daily nature activities, easy walking trails, a discovery cave crawl for kids, and more.

Diamond Caverns

When this cave was discovered in 1859, its first visitors said the area's glimmering stones looked like diamonds, and thus Diamond Cave received its name. The fourth-oldest cave attraction in the country, Diamond Caverns has a lighting system and handrails. The guided tour is a half mile.

Crystal Onyx Cave

Smaller than other Kentucky cave attractions, Crystal Onyx was discovered in 1960 and is now considered an important archeological site because Native American remains—some more than 3,000 years old—were found in the cave. Tours are a half mile and last approximately one hour.

Hidden River Cave & American Cave Museum

Located beneath the city of Horse Cave, Hidden River Cave was once the source of drinking water and hydroelectricity for the community. Groundwater pollution led to its closing in 1943.

In the late 1980s, the American Cave Conservation Association relocated its national headquarters to Horse Cave to restore Hidden River Cave and open a museum and educational center at the site. A bat rehabilitation center is also in progress. Hidden River Cave is now open to visitors year-round.

Mammoth Onyx Cave at Kentucky Down Under

Discovered in 1799, Mammoth Onyx Cave is part of a larger, Australian-themed attraction called Kentucky Down Under. With kangaroos, a bird garden, gem mining, and an outback cafe, Kentucky Down Under is a popular family attraction. A tour of the cave is included in admission to Kentucky Down Under. 

Onyx Cave is a wet cave that was discovered in 1971 when a parking lot was being constructed. With its beautiful coral, a 40-foot column, and a wall of cave bacon, it was decided that it would be an attractive Kentucky cave tour; it opened in 1973. The cave is 60 degrees and tours are 30 minutes.

(Psst!... If you are in Cave City with the kids, drive by​ the Wigwam Village Inn, part of a motel chain that served as inspiration for the Cozy Cone Motels featured in the Pixar film Cars. )

Outlaw Cave at Kentucky Action Park

Outlaw Cave offers a guided tour of many classic cave formations. The cave was named Outlaw because bandits such as Jesse James hid out here and in other area caves. The natural formations were not only hidden but also large enough for the bandits to ride their horses into.

Where to Camp Near Kentucky’s Incredible Caverns

Thanks to Kentucky’s limestone geology, the state has an incredible collection of caves and caverns–there are over 130 caves in Kentucky, with a mile or more of charted tunnels. Everyone knows about the world’s longest cave system  Mammoth Cave National Park , but the fact that Kentucky has dozens of other caves to explore–including a massive cavern with an underground bike park–might not be common knowledge.

Explore The Mysteries Of These 6 Caves In Kentucky

If you want to avoid the mega-crowds that Kentucky’s national park tends to draw, skip Mammoth Cave in favor of these lesser-known, but equally stunning and mysterious caves in Kentucky.

1. Carter Caves State Park

The Carter County region of the state has the highest concentration of caves in Kentucky. At Carter Caves State Park , you’ll find over 20 caves and a number of ways to explore them, from self-guided tours to a cave crawl where visitors must pass a squeeze test before purchasing tickets. Four of the park’s caves offer guided cave walking tours year-round. For a once-in-a-lifetime experience, check out Cascade Cave, named for it’s 30-foot underground waterfall. When you’ve had enough time underground, pop above the surface and enjoy more than 26 miles of hiking trails in the park.

Camp Nearby: Carter Caves State Park

Luckily for all you spelunkers out there, Carter Caves State Park has an on-site campground with 90 standard electric sites, 31 tent-only sites, and nine campsites for equestrians. The campground is open year-round and has flush toilets and shower houses.

“Primitive camp sites are great!! Nice facilities, limited full hook up for campers. Super nice staff. Beautiful area for day trips or extended stays.” —The Dyrt camper Stephanie W.

Prepare for your next adventure by downloading maps. The Dyrt PRO lets you download maps and campgrounds without cell service. “My alternative to using pro would be to drive back out to cell service”.

2. Crystal Onyx Cave

First discovered by prehistoric people–and rediscovered by modern man in 1960– Crystal Onyx Cave is one of the most interesting caves in Kentucky (when it was rediscovered in the 1960’s, for example, human bones were found in the cave.) Open Memorial Day through Labor Day, this privately owned cave features curtains of stalactites, domes, sinkholes and other natural wonders. Just a quick jump from Mammoth Cave, Crystal Onyx Cave is well-loved by in-the-know cave enthusiasts.

Camp Nearby:  Yogi Bear’s Jellystone Park at Mammoth Cave

Yogi Bear’s Jellystone Park campground offers a range of spacious campsites for RVs, travel trailers, pop-ups, vans and tents. Most sites have full-hookups, but there are a limited number that have water and electric only. The campground also has an array of cabins available to rent.

“Been several times at different times of the year. The summer months fill up quick. Great place to visit on its own or with day trips to Mammoth Cave.” —The Dyrt camper Chris R.

3. Louisville Mega-Cavern

One of the largest caverns in the United States, the Louisville Mega-Cavern is aptly named–it’s approximately 100 acres in size.

What was once a large mining operation is now an adventure wonderland where visitors come to ride the underground tram or zip-line, participate in a ropes challenge course, or ride bikes. In fact, the Mega-Cavern features a 320,000-square-foot underground bike park with over 45 single- and double-track trails. For those that like their cave and cavern exploration with a serious side of adventure, the Louisville Mega-Cavern must be experienced.

Camp Nearby: Jefferson Memorial Forest Campground

About a 20-minute drive from the Louisville Mega-Cavern is the Jefferson Memorial Forest Campground, a large campground with full-hookup, electric/water only, and tent only sites as well as camping cabins. The campground is well-situated to not only the Louisville Mega-Cavern, but also to downtown Louisville and all of its shops, restaurants and amenities.

“This place afforded us the ability to enjoy the city and then kick back at a nice scenic spot. Very great accommodations!” —The Dyrt camper Molly G.

4. Lost River Cave

Donated to Western Kentucky University in 1986, Lost River Cave is a story of conservation and sustainability. Back in 2001, encroaching development threatened to impact the land surrounding the cave, so acreage around the cave was acquired to create a 70-acre park of trails, wetlands, meadows and restored prairie.

Of all the caves in Kentucky, Lost River Cave is home to the only underground boat tour in the state. Visitors to Lost River Cave glide through its entrance on the water before entering a cathedral-like cavern where they’re wowed by the otherworldly limestone formations.

Camp Nearby:  Bowling Green KOA

The Bowling Green KOA is just an 8-minute drive to Lost River Cave. The campground offers an extensive number of campsites for everyone from tent campsites with water and electric through full-hookup RV sites.

“Great campground… close to everything you want to see in Bowling Green. Helpful staff!” —The Dyrt camper Katy L.

5. Cub Run Cave

Considered to be one of the most beautiful caves in America, Cub Run Cave can be seen in it’s entirety during an easy half-mile walking cave tour. During that tour, visitors will be awed by incredible rock formations like cave coral, cave popcorn, and a natural pool that was formed by a dip in the ceiling of the cave.

Cub Run Cave is one of only four caves in the U.S. to have a rare formation called boxwork and visitors report that, step for step, Cub Run Cave has more formations than Mammoth Cave and shouldn’t be missed.

Camp Nearby:  Nolin Lake State Park

Around 20 minutes away from Cub Run Cave is Nolin Lake State Park . The campground at the park has 32 campsites with water and electric and 27 primitive campsites—some of which offer lakefront views. The park also has a restroom and shower building as well as laundry facilities and a shaded playground for kids looking for some above-ground fun.

“I’ve only been here once, but loved the trip. Great swimming, fishing, and hiking around. It’s pretty close to Mammoth Cave and has a ton of places to stay if you wanting to camp.” –The Dyrt camper Andrew S.

6. Diamond Caverns

Another stunning cave with a rich history, Diamond Caverns was discovered in 1859 when a man was lowered into a pit in the ground and saw sparkling calcite formations that resembled diamonds, thus giving the cave its name.

Almost right away, the cave became a tourist attraction and, except for short periods during the Civil War, has been welcoming visitors for nearly 150 years making it the fourth oldest operating cave in the United States. In 1999, new owners purchased the cave and, the next day, discovered the largest room yet in Diamond Caverns. The new discovery remains undeveloped and pristine and–at least for now–has limited access.

Camp Nearby:  Diamond Caverns RV Resort

Located close to both Diamond Caverns and Mammoth Cave, Diamond Caverns RV Resort is a large campground with full hookup RV sites and tent camping sites. The campground also has a dump station, shower house and laundry room. When you’re done exploring the nearby caves, check out the campground’s hiking, biking and walking trails, and the 18-hole golf course.

“Diamond Caverns RV Resort was an enjoyable stay on the edge of Mammoth Cave National Park. Right off of I-65, it’s a short drive to the campground.” —The Dyrt camper Shelly S.

Seven Remarkable Caves to Explore in Kentucky

Explore the best of what Mother Nature has to offer.

For many, the mighty Bluegrass State conjures bucolic scenes of the American southeast: ribbons of pastureland speckled with herds of grazing thoroughbred; spirited festivals and live music performances that capture the spirit of Appalachia; finger-lickin’ homestyle flavors come suppertime; and airy front porches that beckon visitors to slow down and savor a proper mint julep. Derby hats are optional.

But beneath the verdant landscape that forms the backbone of such wildly popular attractions as the Kentucky Bourbon Trail ® and Churchill Downs, lies a jaw-dropping landscape waiting for nature-lovers and adventure-seekers who want to go deeper. Miles deeper, in fact, with more than 130 known caves and caverns that punctuate the state’s rich soil.

Kentucky is home to such an incredible collection of caves thanks to its particular karst topography—rich in porous limestone—that facilitates the extended process of subterranean erosion. Throughout recorded history, humans have flocked to such caverns for reasons ranging from the practical (shelter), to the spiritual (medicinal healing practices and burials) to the purely recreational—and today visitors can walk in the footsteps of these early explorers and marvel at ten million years of nature’s handiwork. Here are seven extraordinary naturally-occurring caves in Kentucky, plus two more of the man-made variety that we think are worth planning a trip for.

Mammoth Cave National Park

Any Kentucky caving list worth its salt and lime(stone) must feature this monstrous cave system in the state’s south central region. Located about a 90-minute drive south from Louisville, Mammoth Cave boasts over 412 miles of mapped caverns to date, making it the world’s longest known cave system, and the park estimates another 600 miles may still be waiting to be discovered. Named an UNESCO World Heritage site in 1981 and an International Biosphere Reserve site in 1990, Mammoth Cave is among Kentucky’s most popular attractions. In addition to cave tours and spelunking, the facility offers ziplining and tons of fossil-spotting. In fact, researchers at the park recently discovered what they called a “trove of fossil treasures” that included more than 40 shark species, along with a variety of other fossils from ice age dwellers.

“Mammoth Cave is the world's longest cave, but it also offers a look into a rich human history that dates back over 4,000 years,” explains Molly Schroer, Management Analyst for Mammoth Cave National Park. “This offers an insight into past cultures and modern societies alike, and shows how people's ongoing curiosity has led them to venture into the vast darkness to find out exactly what lies beneath their feet. I see and learn something new every time I am down there.”

Cumberland Gap National Historical Park

Estimated as somewhere between three and five million years old, the Gap Cave, as it’s known among locals, is still forming to this day, thanks to natural water erosion that is continuing to shape its karst makeup. But in more modern history, this ever-evolving system was actually a well-known feature of the historic Cumberland Mountain Pass, which was an integral Civil War landmark. Both the North and the South occupied the site through a series of skirmishes, culminating in the Union forces defeating the Confederacy in 1863. In fact, the Gap is home to "Soldiers Cave," which is believed to have been a battlefield hospital during these times.

“Gap Cave is steeped in rich history,” explains Carol Borneman, Supervisory Park Ranger for Cumberland Gap National Historical Park. “During the Civil War, soldiers from both the Union and the Confederacy explored the cave with many of them writing their names upon the cave ceiling or wall using the flames from candles. Nearly 300 soldiers' names have been recorded.” To date, roughly 14 miles of this cavern have been explored. Visitors can join a two hour, small-group tour that covers three levels of the subterranean expanse, packed with stunning formations and underground waterfalls.

Carter Caves State Resort Park

With Kentucky’s highest concentration of caves located in this county, visitors will find over 20 of them in one spot at this beloved state park. For those who love a challenge and tight spaces, the real adventure attraction here is the cave crawl, which takes visitors who pass the “squeeze test” through narrow, unlit passages and deep into the cave’s interior.

For those who are less inclined to seek such a physical thrill, visitors do have the option to take a more leisurely self-guided (and upright) tour. Those in the know rave about Cascade Cave, which features a variety of exquisite geological formations and culminates with a 30-foot underground waterfall. Other caverns—such as the easily walkable but still breathtaking X-Cave, or the historical Saltpetre Cave—combine to offer a variety of diversions within the system for all abilities and interests. Outside, there are also more than 26 miles of marked hiking trails, a nine-hole golf course and ample opportunities for canoeing, biking and horseback riding.

Lost River Cave

Visitors to the state’s south central city of Bowling Green will find a truly unique experience at Lost River Cave, a dramatic seven-mile cave system that features Kentucky’s only natural cave boat tour and culminates in a monstrous, cathedral-like cavern. Those who feel a bit more comfortable with their feet planted on terra firma can choose a guided walking tour along the river’s edge instead, and still enjoy all the cave’s many sights, thrills and chills (it’s a cool 57 degrees inside the cave system year-round). Tours offer historical commentary about this cave’s storied past, including the cave’s use by area Native American communities, early European settlers, Civil War troops, and even the notorious Jesse James.

“It’s easy to see why our community is so proud of this beautiful natural treasure,” said Rho Lansden, CEO and Supporting Donor for Lost River Caves. “Through the ages, water has chiseled through limestone, deep in the earth, to slowly create the magnificent passageways that we see today. Even after working here for 20 years, Lost River Cave still amazes me with its beauty.” In addition to the cave’s many allures, guests of this 72-acre park will find a web of above-ground trails through seven natural ecosystems, along with the Flying Squirrel Zipline (and the smaller Lightning Bug Zipline for the kids ages 3-10), plus a seasonal butterfly habitat and a robust education center packed with information.

Hidden River Cave/American Cave Museum

Tucked beneath the city of Horse Cave, Hidden River is one of the largest caves in Kentucky—at roughly 10 miles—and borders nearby Mammoth Cave. So close are these two systems, in fact, that the guides in these parts are used to a familiar refrain from guests: Does Hidden River actually connect to Mammoth? “The best answer is ‘not yet,’” says David Foster, President and CEO of the American Cave Conservation Association, American Cave Museum and Hidden River Cave. “But over the years, many similar systems have eventually connected to the big cave, so there’s reason to believe that one day, the two systems could intersect."

The Mammoth system and future interconnectivity aside, Hidden River Cave has its own rich history: once a source of drinking water for Horse Cave, it was commercialized over the first half of the 20th century resulting in pollution that ultimately led to its closure for several decades. This all changed in the late 1980s with renewed conservation efforts, particularly when the American Cave Conservation Association relocated its national headquarters to the town. This afforded the environmental protections that the cave so needed, along with the creation of a museum, educational system and a variety of volunteer conservation projects. As an attraction today, the cave features the largest single cave room in the entire Mammoth Cave region, as well as a variety of tour attractions including a hundred-foot-long swinging bridge—the world’s longest such suspension bridge inside a cave system.

Kentucky Down Under Adventure Zoo & Mammoth Onyx Cave

Considered to be among the most beautiful and accessible caves in the country, this little gem in Horse Cave, Kentucky, offers plenty of bang for your buck. Writer Pamela Selbert of The Chicago Tribune once wrote that Mother Nature had “decided to shoot the works” here. “Imagine three ‘rooms’ made of caramel-rich onyx,” she continued, “with 20-foot-high ceilings vaulted like a Gothic cathedral, colored in a spectrum of iron oxide-pigmented hues as vibrant as a lingering sunset: rose, gold, yellow and burgundy.” A stunner indeed.

Discovered in 1799, the cave first opened for public tours in 1922, and today is part of a larger Australian-themed park (hence the Down Under designation) created by Bill and Judy Austin, who have infused the attraction with a bird garden, gem mining station and a bevy of marsupials, a nod to the owners’ native Outback. “It’s one of the few places in the United States where guests can pet, feed and interact with over 30 kangaroos,” explains Brian Dale of the Kentucky Down Under Adventure Zoo & Mammoth Onyx Cave. And in contrast to many of Kentucky’s other labyrinth cave systems, Mammoth Onyx Cave is relatively petite at just one-eighth-mile in length and about 30 minutes in duration on foot. “It is a fairly gentle tour, as cave tours go, ideal for both adults and children,” Dale continues, noting that the cave is particularly suited to those who want to see a great number of formations within a short distance or short amount of time. Cave tours are included with admission to the Kentucky Down Under Adventure Zoo.

Diamond Caverns

When it was discovered in 1859, those who were first to behold the glittering calcite formations inside this cave noted that it resembled an array of diamonds. Thus, the Diamond Caverns were born in name. As Kentucky’s second-oldest cave attraction in operation today—and the fourth-oldest such touring cave in the country—Diamond boasts an array of stunning formations within each of its cathedral-like chambers. And thanks to its state-of-the-art interior lighting system, visitors can behold over a half-mile of illuminated pathway, revealing spectacular column formations, curtain or “drapery” deposits, and a rainbow of colorful calcite. With over 160 years of touring history, Diamond Caverns still has secrets in store for us all; just in 1999 as the cave system was transferred to new ownership, a massive new cavern was discovered that is still rather untouched to this day. With its adjacency to the World Heritage Site of Mammoth Cave National Park, Diamond Caverns promises many more such discoveries in the coming decades as parks staff and explorers continue to probe the honeycomb of underground tunnels. With around 350 steps, this two-level tour can be physically challenging, but the sights are more than worth the effort.

Man-Made Caverns

Mega Caverns

What once began as a limestone quarry, with over four decades of mining production in the mid-1900s, Mega Caverns is today one of the most extensive cave systems in the country, and features the largest building in the entire state. Visitors can explore roughly 100 acres of parkland featuring a variety of walking tours, an underground bike park, a subterranean aerial ropes course, and even a zipline adventure—Mega Zips—that clocks in at an adrenaline-pumping two hours in duration. If ziplining isn’t quite your speed, the complex offers a historic Tram Tour that traverses 17 miles of the cavern over the course of an hour; or set out on foot for the 1.8-mile Mega Walking Tour for a glimpse of the cavern at your own pace.

The Gorge Underground

Nestled in the Red River Gorge, the town of Slade appeals to thrill-seekers with its myriad attractions that include rock climbing, ziplining—and even an underground kayak adventure—in addition to the usual hiking, biking and camping opportunities you’ll find throughout the state. The small-group kayaking excursion offers active travelers the chance to explore the old mine up close. Those more suited to leisurely adventures can opt for the one-hour cave boat tour, which reveals hidden sights and secrets within the 100-year-old flooded mine.

If you want to hike, spelunk or simply take in the awe-inspiring sights, Kentucky’s caves and national parks have something for all outdoor adventurers. From monstrous systems with jaw-dropping formations, to leisurely family-friendly strolls, adventure is waiting just around the corner at Kentucky’s remarkable caves.

The Best Caves in Kentucky, USA: Complete List

Kentucky, USA is a hotspot for caving. Due to its unique karst geology, which is rich in porous limestone and encourages the long-term process of subterranean erosion, Kentucky is home to a remarkable variety of caves.

People have flocked to such caverns throughout history for various purposes. Besides practical (shelter) and spiritual reasons (medicinal healing practices and burials), many also came for pure recreation. Today, tourists can follow in the footsteps of these early explorers and admire ten million years of nature’s handiwork.

Here are some amazing caves that are found naturally in Kentucky.

Carter Caves State Resort Park

Crystal onyx cave, cumberland gap national historical park, diamond caverns, hidden river cave/american cave museum, lost river cave, louisville mega caverns, mammoth cave national park.

Visitors to this well-liked state park will discover more than 20 caves in one location, with this county having the highest density of caves in all of Kentucky.

The cave crawl, available to those who pass the “squeeze test,” is the area’s main adventure attraction for thrill-seekers. If you’re the type to enjoy a challenge and cramped quarters, you’ll enjoy this. One of the best parts of Kentucky caves, even when not in wild caves, is the opportunity to test your spelunking skills.

Visitors can take a more leisurely self-guided (and upright) tour if they are less willing to seek such a physical thrill.

Cascade Cave, which has a variety of beautiful geological formations and culminates in a 30-foot underground waterfall, receives high praised by those in the know.

Other caverns, including the historically significant Saltpetre Cave and the easily navigable but stunning X-Cave, work together to provide various entertainment options for people of different skill levels and interests.

More than 26 miles of clearly marked hiking paths, a nine-hole golf course, and plenty of options for kayaking, biking, and horseback riding are all available outside.

Crystal Onyx Cave, located in Cave City, Kentucky, is a mesmerizing underground wonder. Discovered in 1960 during the expansion of a quarry, the cave was opened to the public in 1990. What distinguishes Crystal Onyx Cave is its abundance of rare and delicate onyx formations, which adorn the cavern’s walls, creating a visually stunning and otherworldly environment.

This breathtaking array of colors, includes white, amber, and shades of red and brown. The translucent quality of the onyx makes the formations boast an ethereal glow, unlike anything most visitors have ever seen in person. Visitors can enjoy guided tours that teach about the geological processes that shaped these formations over millions of years.

Crystal Onyx Cave holds historical significance as well, serving as a shelter for Native Americans and early settlers hundreds of years ago. These inhabitants left evidence of their presence in the form of artifacts and historical remnants. This adds a layer of cultural richness to the cave, connecting visitors to the human history intertwined with the subterranean landscape.

The Gap Cave, as it is known locally, is thought to be between three and five million years old. However, due to natural water erosion, it is still forming today.

In more recent history, the iconic Cumberland Mountain Pass, an important Civil War monument, was noted for having an ever-evolving system.

The North and the South held control of the area through a series of conflicts until the Union armies defeated the Confederacy in 1863. In fact, “Soldiers Cave,” located in the Gap, may have served as a battlefield hospital.

Carol Borneman, Supervisory Park Ranger for Cumberland Gap National Historical Park , says “Gap Cave is steeped in rich history.”

Soldiers from the Union and the Confederacy investigated the cave during the Civil War. Many even inscribed their names on the wall or ceiling of the cave using candle flames.

The names of around 300 service members have been noted. The length of this cavern, explored thus far, stretches to about 14 kilometers.

A two-hour small-group trip is available for visitors to explore the three floors of the subterranean space. Enjoy the wonderful sights of some quite unique formations and underground waterfalls.

This is a spectacular Kentucky cave for history buffs and cavers in general, due to its massive size.

Those who first saw the glistening calcite formations inside this cave in 1859 compared them to a collection of diamonds. The Diamond Caverns in Barren County, Kentucky offer the kind of sights you wish you could see when caving.

Diamond is the fourth-oldest such touring cave in the nation and the second-oldest cave attraction still in operation in Kentucky. Each of its cathedral-like chambers is home to a variety of spectacular formations. As a result, the term “Diamond Caverns” was created.

Visitors can view nearly half a mile of lit pathways that exhibit stunning column formations, curtain or “drapery” deposits. In addition, you’ll enjoy a rainbow of colorful calcite thanks to the modern internal lighting system.

Diamond Caverns has been open to the public for more than 160 years. It’s a testament to its diversity that it still holds surprises for all of us. In 1999, just as a transfer to new ownership approached completion, they found a sizable new cavern! This new cavern is still largely unexplored today.

Diamond Caverns promises many more such discoveries in the ensuing decades. This two-level trip can be physically taxing because it has about 350 steps, but the scenery is well worth it.

Hidden River, one of the longest caves in Kentucky at around 10 miles, lurks beneath the city of Horse Cave and borders Mammoth Cave. These two systems are so closely related, that local tour guides grew accustomed to hearing the same refrain from tourists.

Aside from the Mammoth system and potential connectivity, Hidden River Cave has a rich history. It was once a source of drinking water for Horse Cave. Still, over the first half of the 20th century, commercialization led to pollution, ultimately forcing the cave’s closure for several decades.

All of this was altered by new conservation initiatives in the late 1980s, notably after the American Cave Conservation Association moved its national offices to the community.

This allowed for the environmental safeguards that the cave desperately required, as well as the establishment of a museum, educational system, and other voluntary conservation initiatives.

The largest single cave room in the entire Mammoth Cave region, as well as several tourist attractions, including a 100-foot-long swinging bridge—the longest such suspension bridge inside a cave system—are all featured in the cave as an attraction today.

Lost River Cave, a stunning seven-mile cave system that includes Kentucky’s only natural cave boat trip and ends in a vast, cathedral-like cavern, offers visitors to the state’s southernmost city of Bowling Green an exceptional experience.

A guided walking tour along the river’s bank is an alternative for those who would like to keep their feet firmly on solid ground. You can still experiencing all the sights, sounds, and chills of the cave (it’s a cool 57 degrees year-round).

Historical commentary is provided during the tours on the cave’s colorful past, which includes its use by local Native American tribes, early European settlers, Civil War soldiers, and even the notorious Jesse James.

Along with the many attractions of the cave, visitors to this 72-acre park will also discover a network of above-ground trails that wind through seven different natural ecosystems, the Flying Squirrel Zipline (and the more miniature Lightning Bug Zipline for children ages 3–10), a seasonal butterfly habitat, and an extensive information center.

The Mega Caverns in Louisville, Kentucky were once a limestone quarry. Today, this cave system houses an expansive entertainment and adventure destination, among other things. Attracting hundreds of thousands of tourists per year, the sheer size and the diverse range of fun activities are sure to delight you and your family.

Covering around 100 acres, the Mega Caverns are often described as an underground city. Guided tram tours provide the opportunity to gain insights into the cavern’s history, geology, and repurposing. Walking around inside creates a sense of awe and wonder as visitors traverse its underground passages.

More adventurous activities include zip lines and obstacle courses, suspended within the cavern’s cavernous chambers. While wild caves can be challenging on their own, these additions give you an exciting and unexpected dimension to the experience.

Perhaps more interesting is the variety of uses the environment provides to locals.

For example, utilities are 75% to 85% cheaper than building above ground. The cavern is tornado and hurricane proof so any important documents won’t get damaged, like in an expensive vault. Alcohol and chocolate are two other popular items delegated to the 58-degree underground storage room.

Learn more about the Louisville Mega Caverns here .

Mammoth Cave can be reached by car from Louisville in about 90 minutes. It features over 412 miles of documented caverns, making it the world’s longest-known cave system .

According to the park research, there may be another 600 miles of unexplored caves. This enormous cave system in the state’s south-central region must be included on any Kentucky caving list worth its salt and lime (stone).

Mammoth Cave is one of the most well-known attractions in Kentucky. It was designated an International Biosphere Reserve site in 1990 and a UNESCO World Heritage site in 1981. The site includes ziplining, tons of fossil hunting, cave excursions, and spelunking.

Recently, park experts uncovered a “trove of fossil gems”. They found more than 40 different shark species and a variety of other fossils from ice-era residents.

For history buffs, this is an exceptional place to take in some of the world’s most wonderful examples of preservation.

Just ask Molly Schroer, management analyst for Mammoth Cave National Park. She reports that Mammoth Cave offers “a view into a rich human history that spans back over 4,000 years.”

This provides insight into both historical cultures and contemporary communities. It demonstrates how human curiosity has driven humans to explore to incredible depths, fascinated by what exists beneath their feet. Every time you go down there, you end up learning something new.

There are more caves than these, of course. We recommend you make your way through this list of caves, but you might also consider some of the more casual attractions Kentucky offers.

Consider Crystal Onyx Cave , which features a very laid-back tour for the whole family. It’s conveniently located close to Mammoth Cave National Park.

But perhaps the biggest attraction of the state is the Louisville Mega Caverns, with a plethora of fun activities for the whole family. Featuring the world’s only underground zip line, guided tours, and several incredible displays, it’s a great site for just about anyone. Read more about the Louisville Mega Caverns here .

Kentucky's Mammoth Cave National Park boasts the world's longest known cave—more than 365 miles have been explored so far.

Venture Deep Underground in This Breathtaking National Park

With over 400 miles of explored caverns and passages, Kentucky's Mammoth Cave National Park has plenty to offer the adventurous visitor.

Location: Kentucky Established: July 1, 1941 Size: 52,830 acres

Under a swath of Kentucky hills and hollows is a limestone labyrinth that became the heartland of a national park . The surface of Mammoth Cave National Park encompasses about 80 square miles. No one knows how big the underside is. More than 365 miles of the five-level cave system have been mapped, and new caves are continually being discovered.

Two layers of stone underlie Mammoth's hilly woodlands. A sandstone and shale cap, as thick as 50 feet in places, acts as an umbrella over limestone ridges. The umbrella leaks at places called sinkholes, from which surface water makes its way underground, eroding the limestone into a honeycomb of caverns.

Mammoth, the world's longest known cave system, a UNESCO World Heritage site and the core area of an international biosphere reserve, still is as "grand, gloomy, and peculiar" as it was when Stephen Bishop , a young slave and early guide, described it. By a flickering lard-oil lamp he found and mapped some of Mammoth's passages. Bishop died in 1857. His grave, like his life, is part of Mammoth; it lies in the Old Guide's Cemetery near the entrance.

Most visitors see the eerie beauty of the caverns on some of the 10 miles of passages available for tours. Rangers dispense geological lore and tell tales about real and imagined happenings 200 or 300 feet down. The tours are hikes inside the Earth; uphill stretches can be hard going for some visitors. Few seem frightened; people terrified by darkness or tight spots naturally avoid caves. Rangers say they rarely have problems guiding the 390,000 men, women, and children who venture below yearly.

Mammoth does not glamorize the underworld with garish lighting. You never forget that you are deep in the Earth. And nowhere else can you get a better lesson in the totality of darkness and the miracle of light. Usually on a tour a ranger gathers everyone and, after a warning, switches off the lights. The darkness is sudden, absolute. Then the ranger lights a match and the tiny dot of light magically spreads, illuminating a circle of astonished faces.

How to Get There

Mammoth Cave , nine miles northwest of I-65, is nearly equidistant (about 85 miles) between Louisville, Kentucky, and Nashville, Tennessee. From the south, take the exit at Park City and head northwest on Ky. 255 to the park; from the north, take the exit at Cave City and head northwest on Ky. 70 to the park. Airports: Nashville, Tenn. and Louisville, Ky.

Year-round. Underground, all days are about the same; temperatures in interior passages fluctuate from the mid-50s to the low 60s. Summer brings the most people, and frequent tours are offered. Though there are fewer tours the rest of the year, they are less crowded.

• Nat Geo Expeditions

How to Visit

The tours vary greatly; pick ones to fit your time and stamina. All require you to purchase a ticket. Reservations are strongly advised in summer, on holidays, and on spring and fall weekends. For a half-day visit, you might take the Historic Tour, which combines geology with Mammoth's rich history, or the challenging Introduction to Caving Tour. If you plan to stay longer, consider the fairly strenuous four-mile Grand Avenue Tour (there are three steep hills, each nearly 90 feet high). To enjoy the caves safely and comfortably, wear shoes with nonskid soles and take a jacket. Complete your underground trips with a river trip or a walk on the River Styx Spring Trail. The least arduous cave tour (0.25 mile, 75 minutes) is the Frozen Niagara Tour. A modified version of the tour has only six steps each way (plus an optional 49) and is designed for visitors who want a short and easy trip. The toughest challenge is the five-mile, six-hour, belly-crawling Wild Cave Tour, offered daily in summer and weekends year-round. By reservation.

Mammoth Cave National Park is the world's longest known cave system, with more than 400 miles explored.

A Traveler’s Guide to Caves in Kentucky

By waitingforrain28

On July 3, 2022

In U.S. Travel

The caves in Kentucky are some of the most spectacular in the whole world, believe it or not. And with short, road-side tours as well as long, National park- scale explorations, there are options for all levels and interests. Caves have shaped the history, economy, and ecology of Kentucky, and thus they are a must for any traveler to the state who is comfortable with their depths.

Why You’ve Got to See the Caves in Kentucky

Mammoth Caves (c) ABR 2022

If you are a hiker, kayker, or just general nature-nut, the caves in Kentucky should be on your bucketlist. These exceptional underground worlds shaped the history and economy of the state of Kentucky that we know today. They teach us about the geologic nature of the land, and harbor strange and unique creatures.

I have been to caves all over the world. As of 2022, this includes caves in Arizona, Nevada, New Mexico, Arkansas, Belgium, Ireland, the Dominican Republic, Puerto Rico, and Haiti. All of them have captured my imagination, and all of them are beautiful. But none of them was as awe-inspiring as Mammoth Caves. I have never been in such a large cave system before (the longest in the world with over 400 miles mapped). And it felt massive. The tour that we went on walked for almost 2 hours, up and down stairs, and through long passage ways. And this was just one of several tour options that explore completely different parts of the cave, never crossing paths.

Outside of Mammoth, Kentucky is dotted with caves and underground rivers (some man-made). Riding on a boat through a cave is always something that I get giddy about, like a kid. And there were several opportunities to do this in Kentucky – including kayaking!

Furthermore, when you are hiking in this state, you will notice that water has shaped the land everywhere in powerful ways, suggesting the nature of the relationship between water and the geology here. Kentucky has deep gorges, sweeping arches , and rolling hills of forests with water criss-crossing its way to unknown destinations.  

Mammoth Caves National Park

As I mentioned above, Mammoth Caves National Park was one of the most exceptional caves that I have ever seen. It is also the crowning jewel of the caves in Kentucky. It is home to the world’s longest cave system, with over 400 miles of mapped cave. I would love to go back some day and spend 1-2 more days just taking other tours and hiking through the forests.

Domes and Dripstones Tour

Tours cost: $21.00 USD (2022)

When I had the opportunity to visit in 2022, my friend and I took the Domes and Dripstones tour. It seems like a great digest option for caves in Kentucky as it saw a nice slice of the cave. However, my friend was a little concerned about the difficulty of the 2 hour tour. And when I heard the warning from the rangers before we got started, I could see why.

They warned about the 500 steps we would be traversing, and the length of the trek. This really isn’t a tour for everyone. You have to be pretty physically fit for the elevation gain and speed of the walking and be open to squeezing through the cave in a few sections (although nothing too scary). That all being said, an older gentleman with a cane made it through, so it is clear that it can cater to various skill levels with some determination and strength, the tour is very fun.

On the Tour

For this tour, we started by being bused up to the entrance. From there, we followed our massive tour group down through a small door, and into the stairwell that we followed down and down into the depths. I really enjoyed this descent. The stairs weaved their way through various chasms and tunnels. Here and there, you would have to turn to pass through narrow passageways. And at times, you can look under your feet and see nothing but deep blackness.

After that, we sat down for a short lecture and then began walking through some of the more level sections of the cave. Much of it was long, tunnel-like structures formed by flowing water. But towards the end of the tour, you will be brought to a huge room full of formations and complete with the cave waterfall.

You will exit a different way than you came in, making each part of the trail unique.

Many Other Options

Although the Domes and Dripstones tour is said to take you through some of the most beautiful sections of Mammoth Cave, there are loads of other options. This includes an accessible tour with an elevator. And longer tours complete with bathrooms.

On the top side, Mammoth Cave National Park, has a large visitor center with a museum that explores the history, ecology, and geology of the cave system. And there are many trails to be enjoyed as well .

Digest de Español Pequeño

El parque nacional Mammoth Caves es el lograr de la sistema de cuevas mas largas en todo el mundo. Hay 643 kms de esta Cueva que tiene una mapa. Con el parque, hay muchas excursiones en la cueva, y todos son hermosos. Pero, yo se Domes and Dripstones. Este es perfecto para un día en el parque.

Creo que todos de los viajes es en ingles. Pregunte los rangers si hay recursos en Español.

Lost River Cave + Other Small Operator Caves

Lost River Cave (c) ABR 2022

There are many caves in Kentucky outside of Mammoth National Park. In fact, when you are driving through the central part of the state, you will see signs for different caves all over the place. Depending on the experience that you want to have, these smaller cave tour operations are also a great option for the travelers among you.

For me, I always love to ride a boat through a cave. There were a couple options that I found for this right away. The first was Lost River Cave and the Gorge Underground. Due to our route, we picked Lost River Cave. Also, it is worth noting that the Gorge Underground tour is via kayaks and through a man-made network of caverns. The Lost River Cave, on the other hand, uses motorized boats. Their tour takes you on a little float through a natural river that flows under the ground.

Some things to consider when picking a small operator cave tour: (1) location, (2) length of tour, (3) characteristics of the tour, and (4) protection of the cave system.

Lost River Cave

Lost River Cave is a historic cave park with tours, trails, and more. The tours here aren’t quite as substantial as those at Mammoth Caves National Park, and they are a little bit more expensive at $22.95 (2022). That being said, I think that the experience of these smaller operator caves is different by nature. They don’t have the resources of the national park. And in the case of Lost River Cave, they are run by a non-profit. I do like supporting smaller non-profits along with national parks when I can.

In any case, this tour has two parts – a short walk and the boat ride. The walk is through the woods of the park and stops at the historic dance floor at the mouth of the cave. Here you will learn about the history of how the cave was used and the struggle that resulted from a misunderstanding of how water flowed through the cave over time in the early days of European colonialism in the area. The history of tourism here, in conjunction with the dance floor and bar is also very cool. When you approach the cave mouth, you will feel the flow of cool air, and understand why folks in those olden days thought partying here was great.

After you have the chance to explore the story of the cave, you will hop in the boat and slip under the narrow entrance. Once inside, you will power through a short section of the cave. You will explore the beautiful formations at the front of the cave. And your guide will walk you through some of the stories connected with Lost River Cave. These include stories about charging people for magic water, stories of wanted men hiding in the cave, and the impact of highway development on cave systems.

Besides the boat element of this tour, I think it is very cool to compare the more remote Mammoth Cave system with this cave in the middle of a developed area.

Lost River Cave es un cueva con un rio y con viajes en un barco. Es muy tranquilo y interesante porque la historia de este cueva es muy largo. Para un corto escape en un rio subterráneo, este es perfecto.

A Short History of Caving in Kentucky

It might not be too much of a surprise, but caves in Kentucky have shaped many elements of the state that we know today.

In terms of Kentucky’s geology and ecology, the characteristics of the state that allow for such extensive formation of caves impacts many elements of the landscape. Water flows readily across the land and under the land and it shapes both. There are beautiful canyons and gorges in Kentucky. And many of the caves here are formed by flowing waters and decorated by dripping water. All of these things create unique environments for all kinds of plants, animals, and small creatures from insects to microbes.

In terms of history, one of the first people to thoroughly explore Kentucky’s caves after the arrival of European colonists were enslaved men including Stephen Bishop, Mat Bransford, and Nick Bransford . With just rudimentary tools, they delved into the depths of the earth and led some of the earliest tours of Mammoth.

After the civil war, exploration of caves continued in Kentucky, and in the early 1900s, folks were making a living on tours of the caves that they found. This led to intense competition and in some cases, violence. It also caused some explorers to take risks, exploring hard to reach places where they got stuck and lost their life. The most famous of these losses was Floyd Collins , who died in Sand Cave while exploring and getting trapped. You can still visit the cave where he died today at Mammoth Caves National Park.

Land Acknowledgement

The land that we now call Kentucky is the ancestral home of the Shawnee, Cherokee, Chickasaw, and Osage peoples. They have and continue to steward and shape this land for thousands of years, and it is thanks to their wisdom, knowledge, and love for their home that we can now experience this magical place.

Matador Original Series

Kentucky Has Over 130 Caves. These Are the 7 You Don’t Want to Miss.

K entucky is synonymous with a few classic all-American staples: the Kentucky Derby , fried chicken , and baseball bats. So threatening your Derby betting bookie with a Louisville Slugger while simultaneously chowing down on KFC might sound like the ultimate Kentucky experience. You would, however, be missing out on one of the most beautiful and underrated pastimes in the state: exploring the many caves in Kentucky.

Thanks to a unique topography and significant underground erosion, there are more than 130 caves in Kentucky. These caves have served a variety of purposes, from criminal shelters to burial sites and places for medicinal research. Today, many are open for visitors.

Mammoth Cave National Park is the state’s largest and most well-known cave system, with over 412 miles of mapped caverns, but there are plenty of other subterranean grottos just waiting to be explored. From the Outlaw Cave where Jesse James once hid to the surreal, glittering rock formations in Diamond Caverns, these are the must-do adventures in caves in Kentucky.

Lost River Cave: boat tours on an underground river

If cruising through a subterranean cavern on a boat is your idea of the ideal cave experience, head to Bowling Green’s Lost River Cave . The seven-mile-long cave system is home to Kentucky’s only natural cave boat tour, ending in a dramatic cathedral-like cavern. You can also take a walking tour instead along the edge of the underground river. Whether you choose to explore by land or by water, you’ll learn all about the cave’s historical use by Native Americans, European settlers, and Civil War soldiers.

There’s plenty to do above ground, too. Visitors will find a 72-acre park with a large network of hiking trails, a seasonal butterfly habitat, and an education center where you can learn more about the cave.

Hidden River Cave: cross a hanging suspension bridge

Adjacent to Mammoth Cave, Hidden River Cave is one of the largest caves in the state at around 10 miles long. It’s under the town of Hose Cave and was once a source of drinking water for the town, until its commercialization (and subsequent pollution) resulted in its decades-long closure. The cave reopened in the 1980s thanks to the American Cave Conservation Association, which implemented conservation and environmental protections and opened a museum for visitors.

Now, it’s one of the top caves in Kentucky is home to 21 types of flora and fauna, making it a global hotspot for underground biodiversity and one of the most biologically diverse cave ecosystems in the world. The cave also has the world’s longest suspension bridge inside a cave system and is the largest single cave room in the Mammoth Cave region.

Carter Caves State Resort Park: crawl through caves with a headlamp

Carter County has the highest concentration of caves in Kentucky, making it a perfect basecamp if your goal is to visit as many caves in Kentucky as possible. You’ll. find more than 20 caves in Carter Caves State Resort Park alone, including Cascade Cave (with its 30-foot waterfall), Saltpetre Cave, and X-Cave. For a true spelunking experience, sign up for a cave crawl, where you’ll explore the caves by squeezing through narrow, unlit passages. More claustrophobic visitors might want to choose a more leisurely, self-guided walking tour instead. Or stay entirely above ground, where you can take advantage of more than 26 miles of hiking and biking trails.

Diamond Caverns: a multi-level cave adventure

Photo: Khairil Azhar Junos /Shutterstock

While you shouldn’t enter Diamond Caverns expecting to see shimmering diamond-encrusted walls, it’s pretty much the next best thing. When the cave was discovered in 1859, early explorers thought the calcite formations looked like glittering diamonds, making for a truly resplendent sight. The cave is known for its cathedral-like chambers of impressive rock formations, including columns, curtain deposits, and colorful calcite. It also has a sophisticated lighting system, illuminating a half-mile of tunnels.

The cave is two levels and requires visitors to climb around 350 steps, so take that into account before adding it to your Kentucky caves list.

Outlaw Cave: see where Jesse James hid from the law

The aptly-named Outlaw Cave is infamous for its use as a shelter by notorious outlaws, the most notable of whom was Jesse James. But apart from its criminal past, the cave is known for the mist perpetually hanging in the air and colorful rock formations, including massive floor-to-ceiling columns.  To keep the cave as natural as possible, no boardwalks or stairs have been added, though it’s still wheelchair accessible. ONE OTHER THING HERE

Gap Cave: take a guided wildlife and nature tour

Photo: National Park Service

Inside Cumberland Gap National Historical Park , Gap Cave is between three and five million years old, formed by natural water erosion that continues to impact the cave’s evolution. And in that time, this Kentucky cave has developed quite the history. It was a meeting place in prehistoric Native American life and to visited by Civil War soldiers in the 1800s, more than 300 of whom etched their names in the rock. Both the Union and the Confederacy occupied the site at various times, and there’s even a smaller “Soldier’s Cave” that once served as a battlefield hospital.

Inside the cave, you’ll find stalagmites, stalactites, flowstone (a thin rock sheet created by flowing water), and soda straws (spaghetti-like hanging rock formations), as well as wildlife like cave flies, crickets, salamanders, crayfish, bats, and more. The best way to explore the 1.5-mile cave is on a guided tour, which lasts about two hours.

Let’s find your perfect match!

1. Mammoth Caves National Park

Located about 90 minutes away from Louisville by car, Mammoth Cave National Park is a must-visit attraction in Kentucky. With over 412 miles of documented caverns, it holds the title of the world’s longest-known cave system. Even more astoundingly, park research suggests there might be an additional 600 miles of unexplored passageways!

Mammoth Cave has earned significant recognition. It was designated as an International Biosphere Reserve site in 1990 and a UNESCO World Heritage site in 1981. The park also offers ziplining, kayaking and canoeing, and fossil hunting, on top of spelunking. Recently, park experts made a remarkable discovery, unearthing a wealth of fossils, including more than 40 different shark species and Ice Age species.

For history buffs, this cave system is a treasure trove of preservation. There’s evidence of human history in the area dating back 12,000 years, with the cave being in use for at least 4,000. Native tribes even used the cave to mine gypsum and related minerals as far back as 1200 B.C.

Mammoth Cave offers several levels of self-guided and guided tours through the cave system. Excursions range from wheelchair-accessible routes to wild caving tours that require climbing and crawling. They also offer lantern tours which add a historic ambiance and shine a whole different light on the cave formations. While in the park, make sure to pay the extra fee to tour the Mammoth Onyx Cave (aka Great Onyx Cave). The smaller cave boasts more formations than Mammoth Cave, has much smaller tour groups, and has a completely different feel.

2. Diamond Caverns

When Diamond Caverns were first discovered in 1859, the sight of the sparkling calcite formations inside left people awe-struck, likening them to a collection of diamonds. Located in Barren County, Kentucky, Diamond Caverns offers a caving experience like no other. As the fourth-oldest touring cave in the country, and the second-oldest cave attraction still operating in Kentucky, Diamond Caverns has been welcoming the public for more than 160 years.

It boasts cathedral-like chambers adorned with a stunning array of formations. You can explore nearly half-mile of well-lit pathways that showcase breathtaking column formations and delicate “drapery” deposits. Thanks to a modern internal lighting system, colorful calcite formations create a mesmerizing rainbow-like display.

In 1999, during a change in ownership, a sizable new cavern was found and is still largely unexplored to this day. Though it has a long history, Diamond Caverns apparently still has secrets to share. While the journey through Diamond Caverns may involve around 350 steps and can be physically demanding, the stunning scenery makes it a truly worthwhile experience.

3. Lost River Cave

Discover your ideal cave adventure at Lost River Cave in Bowling Green. This remarkable seven-mile-long cave system offers an exclusive experience with Kentucky’s only natural cave boat tour. You’ll glide through subterranean marvels on a boat trip that culminates in a breathtaking cathedral-like cavern. If boat tours aren’t your thing, a guided walking tour along the river’s bank is a fantastic alternative.

As you venture through the cave, knowledgeable guides share interesting historical commentary, delving into its rich past. From the utilization by local Native American tribes and early European settlers to its association with Civil War soldiers and the infamous Jesse James, the cave’s human history is a fascinating one. To deepen your understanding of the cave’s history and geology, make sure to stop by the exhibits in the visitor center.

Above ground, the wonders continue, a 72-acre park awaits, inviting visitors to explore a network of scenic hiking trails. Don’t miss the seasonal butterfly habitat, a delightful spectacle for nature enthusiasts. Thrill-seekers can take a ride through the skies on the Flying Squirrel Zipline, while the little ones can fly on the Lightning Bug, designed for children aged three to ten. Whether you’re a nature lover, a history buff, or a thrill seeker, Lost River Cave promises an adventure for everyone.

4. Hidden River Cave/American Cave Museum

Beneath the city of Horse Cave lies Hidden River Cave . It’s an extensive system stretching approximately ten miles, making it one of the longest caves in Kentucky. The cave’s underground rivers once served as vital sources of drinking water and hydroelectricity for Horse Cave. Unfortunately, commercialization during the first half of the 20th century led to pollution, resulting in the cave’s closure for many decades.

Fortunately, a positive turn of events occurred in the late 1980s when the American Cave Conservation Association made the decision to move its national offices to the community. This move brought about crucial conservation initiatives. As a result, environmental safeguards were put in place, ensuring the cave’s preservation for future generations.

With a new lease on life, Hidden River Cave transformed into an attraction with a remarkable array of features. Notably, the system features Sunset Dome, one of the largest freestanding cave domes in the United States, leaving visitors in awe of its vastness. You can also enjoy several fun attractions, including a 100-foot-long swinging bridge, the longest suspension bridge inside any cave system!

While on-site, pop into the American Cave Museum. Often hailed as “a little bit of the Smithsonian in rural Kentucky,” the museum contains exhibits on the history and fascinating science of America’s natural caverns. Admission to the museum is absolutely FREE for visitors of all ages! Embark on a self-guided tour, spanning two floors. Learn about karst geology, delve into the secrets of groundwater, and uncover the wonders of cave archaeology.

5. Cumberland Gap National Historical Park

Gap Cave is a local treasure estimated to be between three and five million years old and still evolving through natural water erosion. As part of the iconic Cumberland Mountain Pass, the cave served as a shelter for 300,000 settlers as they crossed the Appalachians in search of Western lands. It also played a crucial role in the Civil War, witnessing a continuous shift in control between the North and the South. Following the Union armies’ triumph over the Confederacy in 1863, “Soldiers Cave,” situated in the Gap, is believed to have served as a battlefield hospital, adding a somber layer to its rich history.

Gap Cave is not only steeped in history but also renowned for its massive size. With a length of approximately 8.7 miles, it’s an adventurer’s dream and a treasure trove for history buffs and cavers alike. Embark on a two-hour cave tour delving into the cave’s three floors of subterranean wonders. Marvel at the speleothems including cave bacon, ribbons, flowstone, and soda straws in the incredible Music Room. The cave tour is moderately strenuous, with 183 stairs to traverse. You must make a reservation at least 24 hours in advance for a guided tour.

6. Carter Caves State Resort Park

Carter Caves State Resort Park is a haven for cave enthusiasts and outdoor adventurers, with over 20 caves nestled in one location. This county boasts the highest density of caves in all of Kentucky, offering an unparalleled experience for spelunkers.

Cascade Cave is a particularly impressive gem within this treasure trove of caves, boasting a stunning array of geological formations that culminate in a breathtaking 30-foot underground waterfall. It has earned high praise from those in the know for its beauty and charm. Other notable caverns include the historically significant Saltpetre Cave and the awe-inspiring yet easily navigable X-Cave. Each cave offers unique tours suitable for people of different skill levels and interests.

Bat Cave and Saltpetre Cave offer guided wild cave tours. Pass the “squeeze test” to embark on this daring adventure, exploring tight and challenging spaces that will put your spelunking skills to the test.

No matter your interests or skill levels, this state park has something extraordinary in store for every visitor.

7. Outlaw Cave

Named fittingly, Outlaw Cave has earned its notoriety as a hideout for infamous outlaws, most notably Jesse James. However, beyond its criminal past, the cave is renowned for its ethereal charm, with a perpetual mist hanging in the air, creating an otherworldly atmosphere. The cave’s beauty is further enhanced by its vibrant rock formations, boasting colossal floor-to-ceiling columns that captivate all who venture inside.

In a commendable effort to preserve the cave’s natural allure, no boardwalks or stairs have been added to its interior. Despite this dedication to maintaining its authenticity, the cave remains accessible to all, including wheelchair users, ensuring that everyone can experience the marvels it holds. The park offers guided tours of the show cave as well as more in-depth wild cave explorations. Once you’re finished with the caves, hop on horseback and finish your day on a guided trail ride!

8. Crystal Onyx Cave (Crystal Cave)

Nature’s artistry is on full display in Crystal Onyx Cave ! This glorious cave is located just south of Cave City and is renowned for its breathtaking curtains of stalactites, majestic domes, intriguing sinkholes, and mesmerizing speleothems.

From there, a set of well-maintained stairs lead you into the enchanting depths. The trails within the cave have recently undergone renovations, ensuring a safe and enjoyable experience for all explorers.

9. Louisville Mega Cavern

The last one on our list is a bit of an oddball. The Louisville MEGA Cavern is an awesome sight to behold, but it’s not actually a natural cave. This intriguing cavern was formed in an enormous limestone quarry, where miners tirelessly extracted rock for an astounding 42 years during the mid-1900s for Louisville Crushed Stone.

In 1989, private investors recognized the potential of this hidden gem and acquired it. They saw an opportunity to develop a portion of the cavern into an environmentally-conscious, high-security commercial storage facility. Since the early 1990s, the cavern has been a hub of activity, with vast amounts of recycled materials such as concrete, brick, block, rock, and dirt being used to fill the holes, create floors, and build internal roads.

The construction efforts continue, carving out offices and storage spaces within the cavern. However, with over 4,000,000 square feet of space, there is still much to be explored and developed. Surprisingly, even though it lies underground, the Louisville MEGA Cavern is the largest building in the state of Kentucky, and it holds the distinction of being the largest recycling center in the state when measured by tonnage.

Now open to the public, the Louisville MEGA Cavern offers a one-of-a-kind experience to tour a facility that is not quite cavern, but not quite building, and both natural and completely unnatural all at the same time.

The tour is called MEGA ZIPS and presents an exhilarating 2-hour adventure! Expert tour guides lead you through unexplored areas of the man-made cavern. You can also opt for the MEGA Tram Tour if walking isn’t your vibe. Either way, you’ll explore the history of mining, geology, and recycling in this one-of-a-kind space.

Kentucky Caves Put on a Map

To give you an idea of the different locations of caves, I’ve put the entrance location of well-known caves on the map in blue. I’ve created blue zones for areas that are known to have a lot of caves or good potential.

List of Wild Caves

Wild caves are caves that aren’t managed like the tourist show caves. Generally, there’s no human infrastructure build around them, meaning they can be dangerous.  You should never go in alone .

Also, it means that bats will use them to hibernate. Therefore most of these caves are closed from September 15 – April 15. Please respect the seasonal closure. Also, please leave any cave you find bats in during this period. Disturbing their rest will harm them.

FYI: I won’t give any exact locations (roads or GPS) for these caves, as this goes against the Cavers Code of Conduct (meaning: you should try and find them yourself – that’s the sport). It will, however, give you an idea of how many caves there are and what to look for.

The reasoning for this is that cavers that are able to find these caves themselves probably know how to treat them. So it’s a kind of selection process in which the ‘worthy’ cavers gain access to these caves, and people that aren’t as serious or involved don’t. This helps to protect them.

More Info on the Caves

Mammoth cave.

Perhaps the most famous cave on the planet, Mammoth Cave is the longest cave on Earth, consisting of 400 miles (or 640 km) of passageways. It’s mainly located in Edmonson County, central Kentucky . The Mammoth system is a very stable limestone system, attracting over half a million visitors each year. It’s almost twice as long as its underwater contender, Sac Actun, in Mexico. It consists of very large chambers and long passageways and covers over nearly 53,000 acres (21,000 ha).

Louisville Mega Cavern

The Mega Cavern is actually a building, not a cavern. Situated right in the center of Louisville (at 1841 Talor Ave.), the Mega Cavern used to be a limestone mine. Nowadays you can have a tram-tour of the place, but it’s also used for mountain biking, rope courses, and once a year the holiday lights are displayed there.

Diamond Caverns

Very beautiful wet cave, just outside of Mammoth National Park. Worth the extra mile if you like to take a guided tour. Smaller groups and less crowded than its Mammoth siblings, this is a really great tip for people that like it easy. However, the caves are not accessible without a guide, so definitely not for cavers.

Colossal Cavern

Honoring its name, the Colossal Dome is the largest chamber of this cavern, which is 147 ft (or 44 m) high. The dome is amazingly symmetrical, creating an especially interesting reverb. This cavern consists of many large caverns and halls and is very impressive overall.

Eleven Jones Cave (do not enter)

Eleven Jones Cave is located in the center of Louisville, at the back of the Calvary Cemetery (it’s closed off now).  Do not enter  Eleven Jones Cave, for it has very high levels of CO2, resulting in oxygen deprivation and death. The chance of passing out within minutes is severe. With the last exploration (done in 1967), the cavers needed oxygen tanks to breathe.

I’m Rob, the owner of StartCaving. I enjoy exploring and writing about caves. I live in Ohio and like going out to Ash Cave at Hocking Hills with my family. I plan to hit up more caves across the states in the coming years but until then I will continue to write about them.
