Question: Where can visitors see Tennessee’s largest underground waterfall?

Answer: A favorite destination for 96 years, Ruby Falls, outside of Chattanooga, is home to the tallest underground waterfall open to the public in the United States. Visitors can descend 260 feet by glass-front elevator into the mountain and explore the cavern trail to the tallest cave waterfall open to the public in the United States.
