Since Tennessee lies quite solidly on intense bedrock – Ol’ Rocky Top, anyone? – it’s a bit difficult to get underground. Still, we’ve found a couple of places that juuuuust might get you beneath the surface. If you’re ready to take the plunge, that is.
9) Cumberland Gap National Historic Park
Bordering Kentucky, Tennessee, and Virginia, this neat national park is home to quite a few caves and was likely formed by a meteor. Plus? It's where Daniel Boone and his company came through the Appalachian Mountains.
8) Rock Island
Did you know that Twin Falls, the gorgeous mainstay of Rock Island, gushes from underground caverns? That's radically cool, if you ask us.
7) Worley's Cave
Worley's Cave has won the best natural spelunking spot in the state of Tennessee, which makes us feel like this is a pretty awesome underground spot.
6) Underground Chattanooga
Did you know that Chattanooga built its current city right on top of the old one? There are hundreds of underground pockets, basements and old piping that pockmark the underbelly of the city. How did that happen? Intense flooding. Apparently, the city has grown upwards an entire story!
5) Cumberland Caverns
Cumberland Caverns is the spot to go if you're looking for an eyeful of stalagmites or stalactites!
4) Bluegrass Underground
PBS airs the neat underground show, but did you know it became a mainstay in 2008? Cumberland Caverns is the host to this cool monthly music event.
3) The Bell Witch Cave
Maybe you don't actually want to go underground here...? But Adams, TN plays home to the Bell Witch and her cave. This is a fun tourist spot that garners visitors from all over the country - everyone in search of the root of the most terrifying haunting in the US.
2) The Lost Sea
The second largest body of water underground in the world and the absolute biggest in the United States is located in Sweetwater, Tennessee. Pretty neat, huh?
1) Ruby Falls
If you take the guided cave tour at Ruby Falls, you not only get to enjoy the underbelly of the cave world - but you can see a 145-foot underground waterfall. How crazy is that?!
