Tennessee is full of astonishing places to explore, but did you know that it’s also home to the tallest underground waterfall in the U.S.? Ruby Falls, located deep within Lookout Mountain in Chattanooga, is also the deepest underground cave waterfall open to the public.

The falls are accompanied by specialty lighting and music. Expect some misting from the water!

Ruby Falls: Tallest Underground Waterfall in the World

Discovered in 1928, by Leo Lambert, a chemist who loved caving, too, Ruby Falls (named after Lambert’s wife) is a two-and-a-half hour drive east from Nashville. Guided tours begin at 8 a.m. daily with a 260 feet descent in a glass-front elevator inside Lookout Mountain. Next, you’ll walk through the cavern trail to the waterfall amid rock formations. Recorded audio is in a large group format. Once you arrive at the waterfall, expect misting and music. Falling water is accompanied by special music, depending on the holiday.
