We visited Ruby falls while in Chattanooga over a long weekend and really enjoyed the experience. You literally travel over 1000 feet under ground, traversing a cave system that comes out at the falls. This is not an attraction for the claustrophobic. This attraction is a guided tour with lights and various historical references along the way.
This is really the only attraction I would waste my time on at Lookout mountain. The other things are a waste of time.
