Create an itinerary including The Lost Sea Adventure
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. PutThe Lost Sea Adventure into our Sweetwater trip itinerary maker website and find out what's close by, where to stay, and where to head next.

  • I went on 7/4/2021 and it was one of the coolest experiences of my entire life. I cannot recommend it enough!! Took about an hour and a half. It is a guided tour but you can definitely spread out and go at your own pace. The tour guide Brianne was perfect, she answered every single question I had and she made the tour fun. The boat ride was a magical experience. I will absolutely be going back!
  • Outstanding tourist trap. Worth the admission. We did two big tourist things that day and my 9 yr old said this was the best. The boat ride part is the capstone of the tour. Cool cavern tour, but the Sea is the best part for sure. The walking path is fairly wide, defined, and it is easy to follow the tour guide. But sections can be steep. Just a caution to those who may have trouble on a hike.
