Came here with a boy scout troop and camped the night. Fantastic experience. If your troop or group can do it I highly recommend. The tour was the wild one with several crawls. They broke it up so the non crawlers could still see the pretty stuff. Guides kept it light for the boys but took time to answer questions... More

Who would think that there would be a lake under the mountain! After finding our way through the caves,we were taken in a boat onto a part of a lake which resides under the smokey mountain.It really felt out of this world,like something out of a movie.There were fishes that they purposely put in the lake,that survive because of water...

The hubby was here 20+ yrs ago but I've never been. It's been on my list of to do's for some time. We both enjoyed it. Even if there hadn't been a lake we would have went. We enjoy cave tours. May even come back for a wild tour. Greg was pretty funny. I'd recommend him or Brian. (Brian took... More

There isn't a lot else around here so you are pretty much going there to see the Lost Sea Adventure. This was a reasonably priced attraction, I was lucky enough to get put on the next trip 5 minutes after I arrived. The guide was good, entertaining but not trying "too hard". He seemed to know what he was talking... More

The caves are beautiful and grand! The lake was pretty cool. However I do have a few problems with it. The tour is an hour-ish but it really needs to be longer because it was a lot of walking and very rushed. The guide said mostly joking facts, instead of interesting stories or facts the caves. The outside village is... More

My son is 15. I took him here during fall break. He has been caving with some friends of ours, so he was familiar with a lot of the information our tour guide was giving. His favorite part was the actual lake at the bottom of the cave. I knew it would be! He said that when he was with... More

I have taken friends and family to the lost sea and I enjoy it every time I go. It is a long walk down and especially up but the guides are terrific. On the way back up they go slow and stop at times. There are benches for resting as well. My parents who are 85 and 90 both made... More

I just got back from an overnight trip with Boy Scouts to The Lost Sea. I'm glad I went but I'm glad I will never have to go again. The trek into the cave was trecherous! 120+ steps of various sizes and depths that were both muddy and wet. There was a railing for a few steps at the beginning,... More

Took the cave tour with Savannah (sorry if I misspelled your name). What a pretty cave system and a beautiful pale blue lake/sea. Savannah gave us a great tour with lots of interesting, fun facts. The boat ride was the highlight of an interesting tour. I would definitely recommend this 'Adventure' if you are anywhere close to this area, worth... More
