The Largest Underground Lake In The U.S. Is Here In Tennessee And It’s An Unforgettable Adventure

We have a couple of record-breaking feats done right here in the volunteer state, but none are quite as impressive as The Lost Sea, which is the country’s largest underground lake, in Sweetwater, Tennessee. It is an absolutely magical place with its turquoise translucent waters, dynamic lights, and excellent rock formations. You can tour this cave year-round, and we have to say, it is definitely an unforgettable adventure.

Taking a trip to the underground Lost Sea in Sweetwater, Tennessee, is a blast for the whole family. Seeing the unique rock formations, traversing the cave, gliding over the waters of the largest underground lake in the country, and seeing the fish make this one amazing way to spend the day. The cave is open year-round, and we highly recommend taking a trip to experience it for yourself. For more information or to buy your tickets in advance, please visit The Lost Sea Adventure website.
