Located conveniently between Knoxville and Chattanooga, Sweetwater offers a delightful blend of small-town charm and remarkable natural beauty. While the town itself boasts antique shops, local eateries, and friendly faces, it's what lies beneath the surface that truly sets it apart.

The Lost Sea: A Subterranean Marvel
The Lost Sea isn't just a lake; it's a vast cave system with a fascinating history. Originally known as Craighead Caverns, this geological wonder has been attracting visitors for centuries. The Cherokee Indians used the caves for council meetings, and Confederate soldiers mined them for saltpeter during the Civil War. But it wasn't until the early 20th century that the true extent of the underground lake was discovered.
What makes The Lost Sea so special? Its sheer size. While the visible portion of the lake covers about 4.5 acres, divers have explored even further, revealing an astonishing 13 acres of underwater passages and rooms. That's enough to earn it the title of America's Largest Underground Lake recognized by the Guinness Book of World Records.
A Unique Glass-Bottom Boat Tour
The most popular way to experience The Lost Sea is on a glass-bottom boat tour. Imagine gliding across the still, crystal-clear waters, peering down into the depths below. The tour guides are knowledgeable and engaging, sharing stories about the cave's history, geology, and the unique ecosystem that thrives within. You'll see massive rainbow trout swimming below, remnants of past research projects, and perhaps even catch a glimpse of some of the cave's other inhabitants, like bats and salamanders.
The glass-bottom boats are designed for comfort and provide excellent visibility. The tours last about an hour and are suitable for all ages. It's a truly unforgettable experience that will leave you in awe of nature's power and beauty.
