Longhorn Cavern State Park is a scenic park in the rugged Hill Country. It was dedicated as a state park in 1932, was opened in 1938, and was dedicated as a natural landmark in 1971. In 1934, the Civilian Conservation Corps developedd the underground river-formed limestone cavern, mapping passageways, installing more than two miles of lighting, and making improvements to allow 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 on the park. Today, the park features historical and nature study, including guided tours of the cavern.
