People who have gone on the mile-long guided tour of these 30-million-year-old underground caverns beneath the Great Smoky Mountains say they felt like they visited another planet.

Tuckaleechee Caverns is a family-run attraction that earned AAA’s highest rating of five stars. Though the caverns started forming about 30 millions years ago, they are still active, with new formations growing all the time.
Guided tours take you on a mile-long walk on lighted pathways through the caverns. The guides are enthusiastic and knowledgeable. The whole family will learn a lot and enjoy themselves at the same time. There are many photo opportunities along the tour, so get ready to take some great shots.
Water plays an important role in the caverns. The site used to contain inland seas. Today, an underground river runs the length of the caverns. The beautiful formations extending down from the ceiling and up from the floor are created by dripping water leaving mineral deposits behind, a slow process that can take millions of years.
One of the highlights of the tour is the spectacular Big Room, which is longer and wider than a football field. The ceiling is almost 150 feet high and contains other-worldly formations that extend all the way down to the floor. It is the largest room in a cavern or cave that is open to the public in the Eastern U.S.
At the end of the tour, you will come to a beautiful underground waterfall, the tallest one in the U.S. The waterfall drops 210 feet in two tiers. The water there is so clean that people bring bottles to take some home with them.
The caverns also play a role in national security. The bedrock there can pick up vibrations all the way on the other side of the planet. The Department of Defense has seismic sensors installed in the caverns that can detect nuclear tests around the world, as well as earthquakes and hurricanes.
After your tour, don’t miss the popular home-made fudge in the gift shop.
