Did you know Tennessee has more caves than any other state in the U.S.? Be sure to visit Forbidden Caverns in Sevierville, Tennessee. Guided tours, which last about an hour, include a history of the caves — once inhabited by Cherokee Indians and more recently, moonshiners. Be sure to bring jackets, as the caves are chilly.

Tours are offered 10 a.m. to 6 p.m., Monday to Saturday.
