Raccoon Mountain Caverns and Campground

"Get Underground at Raccoon Mountain Tennessee has thousands of caves and Chattanooga itself is full of them. One such is Raccoon Mountain, a family-run cavern and campground that was discovered by Leo Lambert, the same man who turned Ruby Falls into the region's most recognized tourist attraction. Raccoon Mountain is significantly more understated, located on the other side of Lookout Mountain, and hosts families in the summer. The caves are over 5 miles long and their Crystal Caverns tour will give you a taste. Their Wild Cave expeditions allow you to get down and dirty, exploring even more of the cave system. You can even arrange to stay underground overnight."
