Natural Bridge Caverns

Go 211 feet underground to see the deepest part of the largest caverns in Texas. Natural Bridge Caverns -- located near New Braunfels, TX -- continues to be an active and growing cavern system, with water flows causing the underground formations to retain their waxy luster. Visitors can take several different types of guided tours, including the Bracken Bat Flight Tour for an up-close view of the Bracken Cave, home to the world’s largest bat colony.
