Geology Tour

Explore the cavern trail to the thundering underground waterfall on an immersive Geology Tour, where the story of the cave comes to life. Led by a senior-level guide, guests learn how Ruby Falls Cave was formed, uncover the science behind its most fascinating formations, and discover how the cave has slowly changed over thousands of years.

Along the way, spot fossils preserved in limestone, learn what influences how water dissolves limestone, and see how countless years of chemical reactions create formations in a stunning variety of sizes, shapes, and hues. The tour includes extra time at the waterfall, offering a closer look at the towering, water-sculpted limestone walls that frame this natural wonder.
