The Discovery of Ruby Falls

Ruby Falls was discovered by Leo Lambert, a local cave enthusiast, in 1928. While exploring Lookout Mountain for new underground passages, Lambert and his team came across a narrow tunnel that led them to an astonishing sight—a hidden waterfall cascading down a massive rock chamber. Overwhelmed by the beauty of his discovery, Lambert named the falls after his wife, Ruby, and soon after, opened the site for public exploration.

Since then, Ruby Falls has attracted millions of visitors, offering a one-of-a-kind underground adventure. The guided tours take visitors through the deep limestone caverns, showcasing stunning stalactites, stalagmites, and intricate rock formations, before revealing the breathtaking Ruby Falls in all its illuminated glory.

The Geology Behind Ruby Falls

The geological formations surrounding Ruby Falls date back millions of years. The caves were formed by the slow movement of water through limestone rock, creating an intricate maze of tunnels and chambers. The continuous flow of water carved out the caverns, leading to the formation of the stunning waterfall deep within the cave system.

As you walk through the caves, you will witness an array of stalactites hanging from the ceiling, stalagmites rising from the floor, and beautiful flowstone formations, all shaped by the natural process of mineral deposition over thousands of years. These unique geological features make Ruby Falls not just a waterfall, but also a spectacular underground wonder filled with breathtaking rock formations.

The Thrilling Underground Tour Experience

Visiting Ruby Falls is more than just seeing a waterfall—it’s a full-fledged adventure that begins the moment you step into the elevator that descends 260 feet underground. Once inside the cave, a guided tour takes visitors through narrow passageways and vast rock chambers, where they can marvel at natural rock formations, mysterious cave pools, and ancient fossils embedded in the limestone walls.

As you journey deeper into the cavern, anticipation builds until you reach the grand reveal—Ruby Falls itself. The sight of water cascading from 145 feet above, illuminated by colorful lights, creates a surreal and breathtaking moment. The echoing sound of the falling water inside the cave adds to the magical experience, making it one of the most memorable highlights of the tour.
