The Lost Sea Adventure
Guided tours descend through Craighead Caverns to an underground lake crossed by glass-bottom boat, with cave formations, anthodites, mining traces, and layered human history along the route.

Artwork inspired by Bessie Harvey
The lake is spectacular, but the cave’s story includes Cherokee use, saltpeter mining, changing water levels, and a fragile mineral environment. Installed lighting and pathways make one corridor accessible while leaving the larger cave system largely unseen.
Expect a steep paved descent and equivalent climb back; the regular tour is not wheelchair accessible. Boat operation depends on conditions, cave temperature stays cool, and peak-time waits make advance tickets and a light layer worthwhile.
