Beautiful cave tour with light show at the falls. Gorgeous view of Chattanooga from the top of the castle. We have visited many caves in TN, KY and IN and this was the most crowded and popular by far. Single file lines throughout the cave and often having to "pull over" so other groups could pass. If you don't mind large groups in tight spaces, the hour walk to the falls is worth it. My 10 year old loved it too! read more
