The Lost Sea is America's largest underground lake, located in beautiful Sweetwater, Tennessee. We are open every day of the year for tours (except Christmas Day).
You will love our General Store, Ice Cream Parlor, Gem Mine and Glassblower. Our cafe, the Cavern Kitchen, offers sandwiches and real pit barbeque to hungry visitors. Ample picnic facilities and a nature trail are also available.

 


The Lost Sea Nature Trail

The Lost Sea Nature Trail

This trail will take you through a cove-hardwood forest, typical of forest conditions of the Southern Appalachian Mountains around the turn of the century. The forest is made of a community of plants and animals that is considered the most diverse in the world. The trail is a 1/3 mile self-guided trail.
