The CCC cleared Longhorn Cavern and built the road into the hill

Longhorn Cavern was not ready-made as a visitor stop. In the 1930s, Civilian Conservation Corps crews cleared tons of river debris from the cave. Above ground, they built stairs, stone walls, park buildings, and the winding approach through the hills.

That work still frames the trip. The grounds are free to enter, but the cavern interior is seen on a paid guided tour. Tour times and prices come from the park's concession operator.

This is a day-use park at 6211 Park Road 4 S. There is no campground, and the grounds close on December 25. Inks Lake State Park is the nearby overnight option.

The nicest part of the story is visible before the cave tour starts: the road, stonework, and steps turn a hole in the limestone into a 1930s public-works landscape.
