Located just south of New Braunfels, TX and about an hour away from Austin, TX, Natural Bridge Caverns is Texas' largest underground attraction. Make it a day trip for the whole family with activities for everyone to participate in! 

Go down depths to 180 feet and experience cave rooms the size of football fields. For above ground activities don't miss out on climbing the Watch Tower Challenge or visiting The Sluice at Mining Company and Rock Shop.
