Travel: Rocking Hard in Kentucky

When I was a kid, I was easily distracted by cool rocks.  

Who am I kidding? I am still easily distracted by cool rocks.  But I don’t actually know very much about them.  I’m familiar with “sedimentary, metamorphic, and igneous,” but beyond that, I’m always eager to learn more.

It just so happens that one of the most geologically fascinating places in the U.S. is right next door in Kentucky.  Cave experts from around the world flock here to learn more about the geology, biology, palaeontology, and hydrology that can only be found underground.  In fact, in 2023, the Kentucky Speleological Survey confirmed that there are 5,000 officially recognized caves in the state of Kentucky alone.  The reason for this has to do with concentrations of limestone in the area, but I won’t tell you any more. 

You’ll just have to go down there and learn about it yourself.  Allow me to recommend a few stops.

Rocking Above Ground

There isn’t a lot to be found when researching Kentucky Stonehenge, but if Really Cool Rocks get your attention, you should definitely swing by.

After punching in the online address of 201 Lynn Ave, Munfordville, KY 42765, Google Maps led us to what appeared to be a lovely little Mid-Century Rural neighborhood of well-kept ranch houses.  While the serene landscape recalled lovely memories of my grandparents’ home in the 1980s, I wasn’t getting Stonehenge vibes.  Just as I started wondering if my vibes were blocked, the rocks made themselves known.

Munfordville, KY, native Chester Fryer scoured the Hatcher Valley countryside to find the largest rocks available, and with them he built Kentucky Stonehenge and its neighboring parks: Earth Mysteries, The Garden of Gethsemane, Rock Gardens, and Rock Park.  

As you look around, the signs become clear.  You’ll find the parking roundabout by following the signs and arrows.  Hop out of your car, and you’ll immediately bask in the grandeur of Kentucky Stonehenge.

It’s not to scale, of course, since Mr. Fryer was working with local materials.  It is, however, aligned to the cardinal directions and the points on a compass rose.

Take your time, linger, maybe do a little yoga in the center.  The experience is free, so breathe deeply (and check out the little fossils along the sides of some of the rocks).

The Speleological Wonders of Kentucky

The highest concentration of caves within the state of Kentucky can be found in the Cave City/Horse Cave area.  You’ve likely heard of Mammoth Cave, Kentucky’s most famous cave and one of the many National Parks I believe everyone should visit.

But it’s not the only gig in town.  You can get a list/map of some of the caves in the area on the Cave City, KY website, but there’s a better option, which I’ll get to in just a moment.

For my weekend in Kentucky, I chose Hidden River Cave (119 East Main Street, Horse Cave, KY 42749) as my destination.  The history here is amazing.  At one point, the river that flows through the cave was the main water supply for residents of the town of Horse Cave, which is built directly over the cave itself.  

There’s also plenty of biology and ecology to learn at Hidden River Cave, too.  As the town grew, the river filled with pollution.  Eventually, the stench of sulfur fumes became overpowering, and the population began finding other places to live.

With the help of the Caveland Sanitation Authority, the American Cave Conservation Association, and a grant from the Economic Development Administration, Hidden River Cave has been rehabilitated.  Underground species have returned, and the air is a comfortable 50-60F inside the cave.  The air smells like nothing more than dirt and water.

Extreme Undergrounding

No two underground experiences are the same.  Some caves have stalactite and stalagmite formations (such as our own Ohio Caverns).  Lost River Cave offers a boat tour (which I’ll be back to try).  

Hidden River Cave offers the World’s Longest Underground Swinging Bridge.  I didn’t realize that was a category until I started researching Hidden River Cave, but as soon as I saw it, I knew I had to try it.

I also wanted to see the cave’s amazing natural features.  There are 3 domes or “rooms” in the Hidden River Cave.  The first is breathtaking.  The second is massive.  The third is Sunset Dome, which is incomprehensibly large.

Thanks to our tour guide, Jack, I’m fully informed on how water, carbonic acid, and limestone reacted over millions of years to produce these enormous domes.  I’ll let him explain it to you in person, though, because he’s much better at it.  It turns out Hidden River Cave doesn’t have a script, and each tour guide is an up-and-coming expert in various areas of speleology.  Jack’s area of focus is cave survey and mapping, and my tour group learned a ton about the process of mapping a cave.  He took the time to show us a wall of maps at the American Cave Museum, which shares a building with Hidden River caves.  Admission to the museum is free, and I recommend wandering around after your cave tour to learn about all the various types of cave study.

The tour itself only takes about an hour, unless you ask your tour guide endless questions, but there are quite a few stairs involved.  My recommendation is to take as much time as you need when climbing back up the 230 stairs at the mouth of the cave.  I promise you won’t feel awkward, because you’ll get more time to take pictures and ask questions.

Other Stuff to Do 

The next time I head to Cave City, I’ll probably book more than one cave tour.  Most of them have a lot of stairs, so keep that in mind if you choose to follow my lead.

Beyond the numerous unique underground experiences, Cave City itself is a place best explored in the warmer months. Dinosaur World and JB’s Haunted Mansion & Snack Shack were sadly not open when we visited in February.  

I can, however, confirm that The Olde General Store is “the most unique store in Cave Country.”  If you’re interested in Coke bottles or geodes, I can think of no better resource, but honestly, every inch of this shop is an adventure.

Driving to Kentucky’s Cave Country takes about 4.5 hours, depending on how many distilleries and country stores you stop at on your way there.  Whether you’ve got a week to spare exploring the area or want a weekend getaway that’s truly unique, take a look at Hidden River Cave.  

Just don’t look down while you’re on the swinging bridge. (I did.)
