Lost Sea Adventure, Sweetwater
(3.4/5 based on 650+ reviews on the web)
Lost Sea Adventure explores the Craighead Caverns, home to America's largest underground lake. Take the 1.2 km (0.75 mi) guided walk to see the impressive formations. Your guide will tell you about the caverns' varied history, including a period as a Cherokee meeting place, as well as a gunpowder-materials mining site for Confederate soldiers. The tour ends with a glass-bottom boat trip on the massive Lost Sea. Back above ground, explore Old Sweetwater Village, an artificial town full of old-Tennessee charm with food and souvenir stores. If you'd like to see more, take a self-guided walk along the 0.5-km (0.33 mi) forested nature trail.
