The lost sea adventure would begin with a guided tour to the caverns where you would not only get to view the stunning underground lake and the cavern but would get to know more about the interesting geological development of the large cavern rooms and the unique and rare formations. The Lost Sea is a registered National Landmark and the largest underground Lake in America situated in the beautiful Sweetwater. Also, there’s the Lost Sea Nature Trail where you would pass through a beautiful cove-hardwood forest consisting of a community of animal and plants that are said to be the most diverse in the entire world. The caves are very impressive, and the formations are sure to leave you baffled.

The Lost Sea Adventure Reviews & Ratings

  • Very awesome. The cave is super large and looks much different than those in Alabama. The paths are a bit rough so don't get caught up taking pictures, look where you're going so you don't trip. If you cannot hike up to get out then don't take this tour. I feel like this info should be on the website. It's a steady incline for almost all the way back. The boat tour was amazing. It felt peaceful in a way that you don't feel often. Very quiet and the water is cold and clear. There are fish. It really was incredible. My family had a great time. I will be searching for another place that has that vibe for a long time. I'll never forget how it felt to be so far underground in a lake. The history that the tour guide tells you when you're in the boat makes it even more impressive. I'm so glad we went.

  • Husband and I had been wanting to make the trip up and I'm glad we did! It was interesting and the underground lake is amazing! There were a couple issues that detracted from the experience. 1. It was really dark! It was too dark to be able to really enjoy it. I've been to other caverns and mines and they have been better lighted. 2. Our guide went too fast. He spoke too fast and walked too fast. I like to learn when I go to places like this and he didn't really explain anything. All in all though it was really cool and I definitely recommend it.

  • Really huge caverns and great tour. I was impressed with history and knowledge of our tour guide. The walk is easy going down but coming back up be prepared. They do stop several places for everyone to catch their breath though. It's a cool 58* all year in the caves so bring a jacket or long sleeves.

  • We had a great time. Of all of the cave tours I have been on besides the one I rode in a train, this was one of the easiest to maneuver. Wide open spaces, well lit. There were some steep areas but they had resting areas. The boat ride underground is definitely a unique experience. The whole family loved it and I would definitely recommend it for any road trip entertainment.

  • Awesome caverns. So cool to experience where the Indians lived and to boat across the largest underground lake in America. The story about Devils hole is hilarious. Worth every penny. If it were the early 1900's, you could get drunk at the underground bar and you wouldn't really feel the effects until exiting the caves. Be prepared for an uphill walk that will burn those calories.
