Longhorn Cavern State Park is a scenic park in the rugged Hill Country. The state park opened on Thanksgiving Day in 1932 and was dedicated as a natural landmark in 1971. In 1934, the Civilian Conservation Corps formally developed the underground river-formed limestone cavern, mapping passageways, installing more than two miles of lighting, and making improvements to increase public access. In the park itself, an observation tower, one prototype tourist cabin, and cavern entrance compound stairway were also erected, all of cut stone quarried from nearby ranches. Today, the park features historical and nature study, including guided tours of the cavern.
