Ruby Falls

Steve’s take

An underground waterfall inside Lookout Mountain. You take an elevator 260 feet into the earth, walk through a cave, and suddenly there's a 145-foot waterfall lit up with colored lights in a cavern the size of a cathedral. Your kids will think it's magic. Honestly, you will too. Ruby Falls is right at the I-24/I-75 junction in Chattanooga and it pairs perfectly with Rock City if you're doing the Lookout Mountain trifecta.
