The Lost Sea Adventure, Sweetwater

4.1
#5 of 106 in Wildlife in Tennessee
The 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.

  • Steven, my guide, was very informative about the location, and overall he did a great job of answering questions and dishing out facts. Lots of humor but sadly the crowd was tough that day. Moreover, all the guides there sound wonderful after reading the survey book they have outside of the entrance. The accessible part of the cavern isn't as large as you might think, but nevertheless it's a nice place to visit with your family.
  • Their selling point is a boat ride in the cave. Beautiful cavern with a lot of history. You meander through a cavern with awesome rock formation (my favorite was the little grand canyon) then you end up at a dock with boats. The ride is a gentle trip in a boat (trolling motor). This place is truly amazing. Outside a decent set up with a General Store and a Gem mine. There's a Black Smith shop. So lots of things to see and do.
