What are the highlights of the Natural Bridge Caverns?

Your first trip to the Natural Bridge Caverns should start with the Discovery Tour. This hour-long tour takes you past awe-inspiring rock formations such as towering stalactites, flowstones, and soda straws. For a more in-depth view of the cave’s most delicate formations, opt for the 70-minute Hidden Passages Tour which finishes with the lights being turned off and you being plunged into total darkness. Finally, for the adventure junkies there's the 3-hour Adventure Tour where you repel, hike, and squeeze through the wilder parts of the caverns just like the first explorers.

Above ground, try your hand at vanquishing the 50-plus obstacles on the Twisted Trails adventure course, pan for gold at the Mining Company, or find your way through the massive 5,000-sq-ft outdoor maze. Once you’ve built up an appetite, grab a snack or guilty pleasure at Big Daddy’s Sweets, Treats and Brew, or opt for something more filling at the Cavern Café.

A brief history of the Natural Bridge Caverns

Convinced that a large network of underground caverns existed underneath the 60-ft bridge, 4 college students from St. Mary's University in San Antonio obtained permission to explore the area in the spring of 1960. Their first 3 attempts came up empty, but on the 4th, a powerful draft of air attracted the group through a rubble-filled crawlway, revealing miles of underground rooms and passages.

The group immediately knew the significance of what they found, promptly telling the landowners what astonishing natural features lay beneath their land. Eventually, a half-mile walkway was developed in the most spectacular part of the caverns – the Discovery tour route – and it has been accessible for the enjoyment of the general public ever since.

Good to know about the Natural Bridge Caverns

The Natural Bridge Caverns is in the beautiful countryside around 30 minutes northeast of San Antonio. As the attractions are underground, this is a great family activity on a rainy day. Ample free parking is available, so renting a car or using a ride-sharing service is the most convenient way to the caverns. Make sure to buy your tickets in advance. For the best deals, visit midweek to enjoy 20% off the standard weekend charge.

Food and sweets are available onsite, so there’s no need to bring your own. However, make sure to save space for San Antonio’s famous Tex-Mex for dinner. If you’re visiting in the spring, make sure to stop by the Bracken Cave Preserve on the way out to witness thousands of Mexican bats take to the sky.
