Delving Into the Stories of Some of America’s Greatest Caves

National Caves and Karst Day Is June 6 … and Here’s Where to Celebrate

In a country that has a day for everything, of course there’s one set aside to pay tribute to caves. June 6 denotes National Caves and Karst Day, a celebration of those mysterious pits that humans have been exploring for generations … though not always with great success.

This year seems like a particularly good one to acknowledge America’s caves, considering that the story of what happened to one cave explorer has made it all the way to a Broadway stage in 2025. “Floyd Collins: The Musical” shares the story of the man who got trapped in a Kentucky cave in 1925 and created a media frenzy, and the show has been nominated for six Tony awards. Though things didn’t work out so well for Floyd, what happened to him prompted the National Park Service to take control of the country’s biggest cave. But more on that later …

Though today we’re fully focused on caves, it helps to understand what “karst” is, too. That’s the type of topography that’s created when rocks dissolve, and it results in features like natural bridges and sinkholes … and, of course, caves.

MBPR proudly represents destinations in two of the most “karst-y” places in the entire country, western Kentucky and the Shenandoah Valley of Virginia. Each location is home to a variety of caves, and we’re proud to work with three that are especially fascinating. We encourage you to visit them and learn what’s going on under the earth, then emerge to discover some incredible attributes outside the caves, too.

Shenandoah County, Virginia

These caverns are located within the Shenandoah Valley of Virginia, a region that’s incredibly rich in limestone. There are plenty of caves to explore up and down the valley, but we’re particularly fond of Shenandoah Caverns. For starters, it’s the only cave in the state of Virginia to offer elevator service, which means it provides a chance for more people to get inside a cavern and look around. The paths are very wide and most of the ceilings are quite tall. This makes it much more “user-friendly” than caves that feature lots of steps or winding paths.

Something else that sets Shenandoah Caverns apart from most other caves in this region and around the country is the fact that it was formed by both underground rivers and seismic activity. Caves are usually formed by one of those elements or the other, not by both. And a little surprise that’s probably the caverns’ most popular feature is the presence of “cave bacon,” unique formations that looks like everyone’s favorite breakfast meat.

The caverns also just added a new display on June 1. Two years ago, researchers found skulls belonging to a prehistoric animal called the Mylohyus fossilis, or long-nosed peccary (a type of wild pig), in a remote passage in the caverns. They were able to excavate the skulls, which are now being studied, but models have been created so visitors can see what sort of creatures used to live here.

The same limestone that forms the caves also makes the Shenandoah Valley an incredible agricultural region. This part of the United States was once covered by an ancient ocean, and the remains of marine life formed the limestone. The rich soil here is perfect for growing hay, apples and grapes. And you know what comes with grapes … wine! Shenandoah County is home to eight wineries. Of these, Third Hill at DeMello Winery is closest to the caverns, but the others are located anywhere from 10 to 45 minutes away.

Bowling Green, Kentucky

Lost River Cave

Lost River Cave is the only natural underground boat tour in all of Kentucky, which is a big bragging right in a state that’s home to at least 5,000 documented caves. That means that to see inside this cave, you board a boat and take a 25-minute ride through a natural wonder.

The boat is equipped for riders of all types of mobility, so even babes in arms can get their first-ever peek at the interior of a cave.

Besides the cool boat ride and the fact that Lost River runs underneath the third largest city in Kentucky, this cave is known for its famous blue hole, which gets its color from – you guessed it – all the limestone in the area. The cave also has plenty of folklore around it … some stories true, some not so much. It has served as a hunting ground for Native Americans (true), a Civil War camp for both Union and Confederate soldiers (yep), a hideout for the outlaw Jesse James (hmmm… has it?), and the area’s most unusual nightclub (fun fact).

The singers from back in the 1930s can attest to the cave’s dramatic acoustics.

The boat tour is only a portion of what your admission ticket gets you. There’s also a complete above-ground experience that shows off the beauty of the land. There’s an array of trails and a geocaching adventure, and from Memorial Day through Labor Day, the cave’s staff also operates the Charlie Miller Butterfly Habitat.

Town of Mammoth Cave

This isn’t just an example of good marketing … the cave earned its “Mammoth” name because it’s the longest cave system in the entire world. So far, more than 400 miles have been explored, and there’s no telling what lies beyond that. Back in the early 1900s, people popped in and out of this area’s caves with reckless abandon. But an accident in the winter of 1925 at a neighboring cave – a news event referred to as the “entrapment of Floyd Collins” – led to the National Park Service taking over Mammoth Cave and putting incredible safety measures into place. That set the tone for new ways of exploring Kentucky’s “Cave Country.”

These days, Mammoth offers a variety of guided tours, ranging from those that are pretty mild (you can travel in a wheelchair) to some that are kind of wild … perhaps exploring by lantern-light or squeezing through on your hands or knees. Mammoth is an incredibly popular cave, so making a plan and booking your tour early is essential, especially in the summer months. It’s important to note that these days, everyone who enters the cave comes back out again safely, so there’s no fear of someone’s adventure turning into a Broadway musical 100 years from now.

A fun part of any cave tour is experiencing a natural wonder in the dark … but the bonus here is that you don’t have to be underground at Mammoth to do that. This national park is also an official “Dark Sky” park, meaning that the absence of city light results in some incredible stargazing.

In honor of National Caves and Karst Day, make plans to get out there – and get UNDER there – and do some exploring!

Just in Time for Halloween: Going Batty for Bats

Going to Bat for … Bats!

Going batty, bat guano crazy, bats in the belfry–these are a few of the less than enduring terms applied to what may be one of nature’s most misunderstood creatures, often depicted by myths, books, and movies as being ruthless, bloodthirsty and generally not fun or cudddly at all. Well, we have to agree there’s nothing cuddly about bats. Weird looking creatures who like to sleep upside down in caves and trees, but as far as we know they’ve never driven anyone crazy or indulged in any vampire blood drinking throwdowns. Instead consider this: Bats are incredibly important to the ecosystem and by pollinating plants and eliminating pests, they save American farmers billions of dollars a year by preventing crop damage and helping eliminate the cost of pesticides.

So why not pay homage to these winged creatures during International Bat Week that runs from October 24th to, appropriately enough, October 31st better known as Halloween making it a perfect time for a bat road trip. Yes, you read that correctly.

Which brings us to Mammoth Cave National Park near Bowling Green, Kentucky

Yes, the name says it all. The cave is absolutely mammoth … the longest and largest cave system in the entire world and one of the oldest tour attractions in North America with some 426 miles have been explored and at least another 600 miles to go. In other words, as huge as it seems, less than half of the cave is what you see. Rangers are on hand for guided tours through what is one of the oldest tour attractions in North America and are experts at pointing out all the wildlife on the property. That, of course, includes bats. A total of 13 types of bats have been confirmed at this national park, with two other species reported but so far that hasn’t been confirmed.

But don’t look for all the bats in the cave. Sure some are including species that live in the cave while waiting to give birth or during their very long winter naps–a hibernation lasting from mid-October to mid-April. Other species choose to hang out (and we do mean hang) in trees, under bridges, and the eves of buildings around the park.

The federal government had declared that three of Mammoth’s bat species are either “threatened” or “endangered.” Both the Indiana bat and grey bat are considered endangered; the northern long-eared bat is threatened.

Scientists at the national park constantly monitor the health of the bat populations, and the parks hosts occasional public “Bat Nights” at which visitors are invited to watch as bats are captured from the cave, assessed and released.

Immerse yourself in all things bats by becoming a Bat Biologist during Mammoth Cave’s annual Bat Night.

Because Lost River has a body of water inside the cave, it’s prone to dampness and flooding … which doesn’t work for bats.

Occasionally a young male bat will enter the cave looking for love … but when he doesn’t find a girlfriend, he heads back out.

Marvel Cave in Branson, Missouri

Then head to Marvel Cave, the deepest cave in Missouri (383 feet below the ground at its deepest point) which today is located near the entrance to Silver Dollar City, one of the nation’s most celebrated theme parks. Interestingly, the park evolved from the cave, which was Branson’s first tourist attraction.

The Osage Indians discovered the cave around 1500 and was regularly explored starting in the late 1800s by miners searching for marble and lead. What they found instead was lots and lots of bat guano. You might be thinking that’s a load of crap but consider this. Bat guano at the time was used for both fertilizer and ammunition and for those willing to mine it, the payoff was $700 a ton or more than $20,000 in today’s dollars) per ton. Yes, back in the day, you could get rich off bat poop!

Missouri is nicknamed “The Cave State,” and that means it’s also home to lots of bats. Of the 46 species found in this country, a third – 16 – call Missouri home. Of the 16, four species live in Marvel Cave, including two types of brown bats, plus tricolor bats and endangered gray bats. But, unfortunately, because of disease, pollution, and pesticides, the bat population inside the cave is about a tenth of what it used to be. These days, there are only approximately 40,000 bats at Marvel Cave.

The best time to see them is during the last two tours of the day. During those evening tours, guests stand a good chance of seeing bats in the cave’s Mammoth Room and Cathedral Room.

Silver Dollar City loves its bats and pays homage to them at its annual Harvest Festival where pumpkins are carved to look like bats.

Bat Facts*: Gaining an Appreciation for Fascinating Flying Mammals

🦇Bats are the only mammals capable of true flight. (Take that, “flying” squirrels! You guys glide, not fly.)

🦇There are more than 1,400 bat species around the world, with 46 species found in the United States.

🦇Since bats are mammals, they give birth to live young. A baby bat is called a “pup,” and most mamas give birth to just one per pregnancy.

🦇Bats clean themselves much like cats do. They spend a lot of time grooming … so they always look good for the humans who get those rare glimpses of them!

🦇You’ve heard the term “blind as a bat.” Compared to other animals, bats do have very poor eyesight. But they more than make up for that by having incredible hearing and amazing brains.

🦇Most bats are nocturnal, so they have special adaptations that help them get around and find food in the dark. They can fly fast and track small prey using “echolocation.” This means they emit high-frequency sounds that bounce off objects. They listen for those echoes and then their brains interpret the sounds so they can figure out what the object is. This is what allows them to avoid crashing into things (and each other) while grabbing insects to munch on mid-air.

🦇If you have mosquito problems in your backyard (if you have a pool back there, for example) but are hesitant to use pesticides, consider taking the natural route and using bats to combat the pests. You can make a “bat house” to try to attract them. A bat can eat its body weight in insects in each night … and that can be up to 600 mosquitos!

🦇Climate change is making life incredibly difficult for bats. Heat waves and droughts cause overheating and starvation; wildfires destroy habitats; storms and heavy rainfall impact caves and flood bat roosts; and freezing temperatures block cave entrances or cause bats to freeze to death.

🦇A big risk for bats today is “white-nose syndrome,” a fungal disease that spread rapidly up and down the East Coast and has now moved across the country. The fungus, which appears as a white, fuzzy growth on the nose, doesn’t kill the bat. But the itching from the fungus causes bats to wake up during their hibernation – when there are no insects to eat – and results in the bat slowly starving to death. Though scientists have tried several ways to help bats build an immunity to the fungus, bat populations have plummeted in recent years.
