ADA Accessibility Notes

Not Handicap accessible due to the steep incline into the cave.

Stroll through an 18th century village, explore huge fascinating caverns, then float across America’s largest underground lake!

In times past deep inside a mountain near Sweetwater in East Tennessee is a remarkable body of water known as The Lost Sea. Listed by the Guinness Book of World Records as America’s largest underground lake, the Lost Sea is part of an extensive and historic cave system called Craighead Caverns.

The caverns have been known and used since the days of the Cherokee Indians. From the tiny natural opening on the side of the mountain, the cave expands into a series of huge rooms. Nearly a mile from the entrance, in a room now known as “The Council Room,” a wide range of Indian artifacts including pottery, arrowheads, weapons, and jewelry have been found, testifying to the use of the cave by the Cherokees.
