You Can Take A Boat Ride Through America’s Largest Underground Lake! (Sweetwater, Tennessee)

Thanks to Narcity for this:

Located about 45 minutes south of Knoxville, The Lost Sea is a gem that needs to be visited.

This spot is America’s largest underground lake and it’s in Sweetwater, Tennessee.

It is the 2nd largest underground lake in the world.

The water is at least 70 feet deep.

Since opening to the public in 1965, visitors can take a tour every single day of the year, with the exception of Thanksgiving and Christmas Day.

The caverns are part of a historic cave system called the Craighead Caverns.

They’ve been used for thousands of years and a plethora of Cherokee Indian artifacts have even been found throughout the caverns.

The tours start with a simple guided walk-through in the actual caverns before visitors descend 140 feet underground for the boat excursion.

The walking tour is about a quarter of a mile long and the guides will talk about the history and the geological aspects of the cave.

This lake is a crisp 58 degrees at all times.

The boat will go through various rooms of the caverns and guests will be able to see “cave flowers” and various rock formations.

There’s also a general store, an ice cream parlor, a cafe, a gem mine, and even a glassblower guests can experience during their visit.
