5Q: What is the difference between the Discovery Tour and the Hidden Passages Tour?
A: Both tours are similar in duration and walking distance. Both tours are also approx. the same depth (180 feet). The Discovery Tour is our original tour where you will see large formations and several large cavern rooms including the largest cavern room in Texas. The Hidden Passages Tour offers a closer view of smaller more delicate and unusual formations. The Hidden Passages Tour also utilizes a state-of-the-art lighting system which uses both light and darkness to dramatically present the cavern to guests. Finally, the Hidden Passages Tour has a "Total Darkness" demonstration as part of the experience.
6Q: It’s raining. Is Natural Bridge Caverns open?
A: Yes. Tours continue even if it rains. Please call before coming out if there are unusually hazardous weather conditions such as heavy thunderstorms or icy roads.
