About Longhorn Cavern State Park

Longhorn Cavern State Park near Burnet features an underground cave system formed by an ancient riverbed, where visitors descend 52 stone steps into a constant 68-degree environment.

Additional attractions include gemstone mining in a sluice where visitors uncover natural treasures, crack-your-own geode experiences revealing crystals formed over thousands of years, and a blacklight tour using specialized flashlights to reveal hidden cave features. The park also operates a gift shop with in-house designed apparel, a snack bar serving pizza and ice cream, and scenic walking trails above ground. The site suits families, school groups, and adventure seekers of varying fitness levels. Visitors can explore the historic CCC buildings and picnic areas surrounding the cavern.
