Exit 4 off I-24 in TN. Wilma Rudolph Blvd. to Dunbar Cave Road. Turn left and follow DC Road to the cave area and Swan Lake, which are on the left.
Turtles line up and sun on a log in Swan Lake with the cave archways in the background. While concerts used to be held in the cave area, it is now an empty walkway traveled by many. Dunbar Cave is home to a large colony of bats, and a "Bat Walk" is held each year for photographers to "hopefully" catch them in flight as they leave for their evening of hunting.
