Natural Bridge Caverns

26495 Natural Bridge Caverns Road

History and Discovery

In March of 1960, Orion Knox Jr., Preston Knodell, Al Brandt and Joe Cantu, four college students from St. Mary's University in San Antonio, obtained permission to explore the area that is now Natural Bridge Caverns. The students were convinced that large underground passages existed under the amazing 60-foot limestone bridge. On their fourth expedition, Orion felt a cool draft from a rubble-filled crawlway. Such air currents often indicate the presence of additional rooms or passages.

The explorers made their way carefully climbing and crawling through two miles of vast cavern passage. After making this amazing discovery, they returned to the surface to tell the landowners. The discoverers knew immediately what an astonishing find they had made and the land owners decided to develop the first 1/2 mile, the most spectacular part of the caverns, for the enjoyment of guests from around the world. That first 1/2 mile is now the Discovery Tour. Natural Bridge Caverns Discovery Tour was developed with two main goals in mind: preservation of the cavern environment and comfort of its guests. The result is one of the world premier show caverns, and one of the most popular attractions in Texas.

If you have the time, I would absolutely recommend checking out. The cave systems are massive and very beautiful. The pathways are easy enough to traverse so bringing children shouldn't be an issue. There are a couple of tours to take. The more adventurous may want to take the adventure tour, if I remember correctly. You get to go into the smaller tunnels in the caves. The gift shops are good sized and have great souvenirs to take home.

Beautiful cave! Our tour guide was very knowledgeable. Active duty military members may enter for free on the discovery tour. The caves are not cold. They're very humid and wet so wear non slip shoes. I would not advise bringing children who are not expert walkers. Some of the tour is up and down steep pathways (and slippery). Tour was about 60 min.

Another unusual cavern in Texas--characterized by startling groups of slender stalagmites. Visually stunning, plus I felt safer because they had put down a non - skid surface. The grounds are fun as well, with a zip line and climbing challenge. The natural bridge is interesting, but upstaged by the cave beneath!

Definitely worth a visit. Very interesting formations. It's pretty hot and humid in the caverns. I would recommend going as early as possible to avoid crowds. The hidden passages tour is very good. The discovery tour was also good but more crowded.

Very expensive but fun. About a 30 minute cave tour and you go 180' deep. Very good tour guides that are very nice. After you are done, they have a concession stand with food and sweets. There are 2 gift shops with cool souvenirs. There is a restaurant too with great options like hot dogs, sausage on a stick, fudge, and more. There is a great walk around plaza with a zip line and a physical activity adventure.
