The Lost Sea Adventure

The Lost Sea Adventure is e. on SR 68, following signs to 140 Lost Sea Rd. This 4.5-acre underground lake, stocked with rainbow trout, is reached via a .75-mi. walk on sloping pathways and explored by glass-bottom boat. Rock and mineral deposits and cave flowers can be seen in Craighead Caverns. During the Civil War Confederate soldiers mined the caverns for saltpeter, a mineral used in gunpowder. Later, settlers stored food in the 58-degree-Fahrenheit cave. In the 1900s townsfolk created the Cavern Tavern, a natural party room.

Old Sweetwater Village, across from the main entrance of Lost Sea, is a re-creation of an 18th-century village. Log cabins feature a general store, a blacksmith shop, a candy shop and craftsmen demonstrating such traditional skills as glassblowing.

Guided tours are available. Picnicking is permitted. Food is available. Time: Allow 1 hour, 15 minutes minimum.
