Go deep into the depths of the Natural Bridge Caverns to cool off from the Texas sun and summer heat. You can take a 75-minute tour down 180 feet below ground to see stalagmites, flow stones, chandeliers, stalactites, soda straws and more. This adventure will be filled with energy, education and exciting experiences. You don’t have to be an avid caver to experience Natural Bridge; the cavern tour is appropriate for all ages. Though even if you are, it’s always a fun memory for everyone who tries it.
In March of 1960, Orion Knox Jr., Preston Knodell, Al Brandt and Joe Cantu – four students from St. Mary’s University in San Antonio – received permission to explore the area of Natural Bridge Caverns. Convinced that there were large, underground passageways underneath the 60-foot limestone bridge, they went on four expeditions. On that fourth trip, they finally got lucky.
The four explorers climbed and crawled through roughly two miles of cavern passages. After their exhilarating discovery and adventure, they climbed and crawled their way back to the surface to inform the landowners of their incredible find. The landowners developed the first half-mile into a passageway for guests from around the world to explore. This half of a mile is arguably the most remarkable section of the caverns.
Now, you can explore the depths for yourself. Find all of the formations from centuries ago, some of which are still growing. Make sure you bring your camera to capture these moments and sights forever!
Natural Bridge Caverns is the largest cavern in San Antonio. It is also one of the largest in the state of Texas.
While you’re on the Natural Bridge Caverns property, try out the Canopy Challenge and zipline. You can also choose to venture further into the cavern, into some darker areas.
