Longhorn Cavern State Park near San Antonio

What are the highlights of Longhorn Cavern State Park?

All visits to Longhorn Cavern State Park must start with either the Walking or Wild Cave Tours of the namesake Longhorn Cavern. To protect the fragile environment, access to the cavern is only possible on one of these guided tours.

The 90-minute Walking Tour follows an ancient underground riverbed and room after room of incredible geological marvels. After descending 130 ft below ground, you can explore the sparkling Hall of Diamonds and rugged Gunpowder Room.

Alternatively, the 3-hour Wild Cave Tour is a more primitive experience. You crawl and wriggle through undeveloped caverns, getting dirty and wet, but which is a lot of fun throughout the journey. You even receive a free Wild Cave Tour Finisher T-shirt to commemorate your achievement. Finish your adventure with an open-air walk along the above-ground nature trail or with soft-serve ice cream at the onsite deli-snack bar.

A brief history of Longhorn Cavern State Park

To appreciate the unique history of this state park, you must understand its natural and cultural-historical influences. Crafted by numerous underground lakes that dissolved and eroded rocks over millions of years, the park is an example of the powerful results of slow-moving water cutting deep into the limestone. The result is an array of wonderful stalagmite rock formations, gaping sinkholes, sparkling crystals, and bizarre rock carvings only nature could've created.

Longhorn Cavern’s cultural history rivals its natural one thanks to its legendary reputation in local folklore. The cavern has had many unique lives before becoming a tourist attraction of Texas. It served as the council meeting room of local Comanche tribes, a hideout of famous Wild West outlaw Sam Bass, and the site of a raunchy prohibition-era speakeasy.

During the 1930s, the Civilian Conservation Corps went to work with picks and axes for 8 years to excavate the rock, eventually resulting in the accessible cave we have today.
