how deep is ruby falls

Ruby Falls is an underground waterfall located about 1,120 feet (340 meters) beneath the surface of Lookout Mountain in Chattanooga, Tennessee.

Key Facts

This makes it one of the tallest and deepest underground waterfalls open to the public in the U.S., with the waterfall itself dropping 145 feet (44 meters) into a pool below. Visitors descend via a high-speed elevator that travels 260 feet straight down into the cave system, followed by a guided walking tour along paved paths with electric lighting.

Discovery Story

In 1928, Leo Lambert drilled into the mountain searching for a new cave entrance and stumbled upon the hidden chamber. He named the falls after his wife, Ruby, after bringing her to see it—adding a touch of romance to this natural wonder formed by millions of years of water erosion through limestone.

Visitor Experience

Tours run frequently, lasting about 1-1.5 hours, showcasing stalactites, stalagmites, and dramatic lighting at the falls. It's a hugely popular spot, though some online chatter questions if the lights make it feel artificial—yet sources confirm the falls and formations are natural.
