My name is Chris Dodge and I live right here in the great state of Tennessee. My family and I are full adventurers filled with passion to see the amazing things our state has to offer. We are avid hikers and have explored many different places in Tennessee and beyond but we are always thankful to be living in such a glorious state.
We have a couple of record-breaking feats done right here in the volunteer state, for instance, Ruby Falls. This is the tallest free-falling waterfall open to the public in the country, pretty impressive right? For today, I want to take you to another mind-blowing underground attraction. Craighead Caverns is known as The Lost Sea Adventure and this is one of the most interesting caves we have in the state — that’s saying a lot for a state with 10,000 caves. This phenomenal geological wonder 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 to Craighead Caverns 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.
