Everything is bigger in Texas, including the caverns. See the Natural Bridge Caverns, the largest of its kind in the Lone Star State, near San Antonio on a guided walking tour. An experienced and informative guide leads your group through this National Natural Landmark, revealing the science and history behind the magical underground rock formations along the way.

The 75-minute tour takes visitors 180 feet (55 m) underground to discover cavernous hallways and rooms highlighted by otherworldly stone structures that were only discovered in 1960. Throughout the nearly mile-long (1 km) walk, youll see fried-egg speleothems that seem to drip from the ceiling.

After the subterranean tour, partake in some of the above-ground activities (own expense) on the grounds. Soar above Texas Hill Country on one of two ziplines; race through the AMAZEn Ranch Roundup; or test your stamina on a circuit of ropes, planks, and stairways on the Canopy Explorer Course.

  • Really enjoyed the walking tour. It's easier going down than coming up :

  • Very good

  • Interesting but not great. Found the walk testing as we had to descend 180 feet into the caverns and then climb a path and steps back up the 180 feet which I found to come close to my limit. This information should be published on the booking site as you can not cancel after booking the tour. It is only included in the information sent together with your booking confirmation. Too late!!!

  • This tour was amazing!

  • Easy to walk through.

  • Well this is interesting Tour however, I highly recommend to be somewhat fit or younger age. It is wet inside ground and hand rail,the humanity high and dark cave so need to watch steps, walking has narrow space while entering. One needs to be careful because it is 180 feet below, the most difficult part is the steep walkway to get out. I had trouble trying to catch my breath and my spouse could not make it out, he needed help. I liked the Tour and was upset that there is no easy way out for those who need it!

  • It was what I expected. The guides were knowledgeable and friendly. The price was reasonable. I would do it again, just for the beauty of the caverns

  • Great tour.
