Down and Dirty Adventure!

Feed your appetite for exploration and adventure with Natural Bridge Caverns Adventure Tours!
These unique wild cave expeditions take you to areas in the cave not seen on our regular tour and give you the chance to learn what it’s like to really explore caves. We have two distinct tours – and even a full day for adventure if you’re up for it. Come on down for a naturally fun and physically demanding experience right off interstate 35, between San Antonio and New Braunfels, Texas.




St. Mary's Adventure Tour

NEW Tour! The St. Mary’s Adventure Tour is a unique caving expedition through a beautiful wild cave area of the Discovery Cavern. Sections of these passages include rare formations including black calcite, stunning calcite box work, and even formations that ring like a bell. You’ll learn to use some professional rope techniques used by cavers for traversing, ascending, and descending within the cave just like a real member of our expedition team.

Plan on 2-3 hours from start to finish.

$129.99 per person.

Discovery Adventure Tour

The Discovery Adventure Tour recreates part of the experience of original explorers in the early 1960s. Our experienced staff guides you through a wild cave trip where you will climb, hike, and explore caverns full of natural beauty in the making for thousands of years. Walk through the standard Discovery Tour before going off trail where there is no commercial lighting, paved paths or handrails, but plenty of raw adventure.

Plan on 3.5-4 hours from start to finish.

$169.99 per person.

Underground adventure at its finest!

These are not your typical cavern walking tours, but an exploration of natural beauty in the deepest recesses of the earth.

Face the challenge. Stop, drop, crawl, climb and slide through these exciting excursions.

Don't forget to add this tour to your list of popular things to do in Texas.

Both tours are muddy adventures.

You’ll get down and dirty in both tours, but there are some differences between the two.

The NEW St. Mary’s Adventure Tour is a more technical tour with no crawling, more climbing, and takes 2-3 hours.

The Discovery Adventure Tour is a more physically demanding, involves muddy and tight crawlways and takes 3.5-4 hours.

You’ll see the difference between the developed caves and the serene, untouched beauty of their natural state.

Be brave, be strong, and strike out on an adventure you won't soon forget with Natural Bridge Caverns Adventure Tour.
