Here in Tennessee, we pride ourselves on the beauty of our state. Every road you drive is going to have something uniquely beautiful and interesting, and the roads outside of Townsend in East Tennessee are no different.

The caverns are open from 10 a.m. to 5 p.m. from mid-March to mid-November. You can visit them and see what explosions and earthquakes the cave detects. They are located outside of Townsend at 825 Cavern Road.
