Longhorn Cavern State Park
Burnet, TX
A river-carved cave used by Comanche people and later as a speakeasy, with a CCC-built stone visitor center from the 1930s. Guided walking tours take about 90 minutes; the cave stays around 20 °C all year.
Longhorn Cavern State Park is a 645-acre (about 260 ha) state park in the Texas Hill Country between Burnet and Marble Falls, whose main attraction is a cave. It formed as seeping water dissolved Ellenburger limestone, which was deposited about 500 million years ago in a shallow sea. Access is via Park Road 4, which runs about 6 miles from US 281 to the park entrance.
According to tradition, the Comanche held councils in the largest chamber, the Indian Council Room. In the 1920s, D. G. Sherrard ran the cave during Prohibition as a dance hall and restaurant. The state acquired the land in 1932, and the park opened in 1938. From 1934 to 1942 the Civilian Conservation Corps worked in the cave with about 200 men, hauling out soil and rock, lighting more than 2 miles and using much of the excavated material to build Park Road 4.
For road-trippers: the cave stays at a constant 68 °F (20 °C). The main tour takes just under 1.5 hours, covers about 1.25 miles and begins with 52 steps down; there is also a three-hour Wild Cave tour. The tour details date from 2004; check current tours in advance.
