Longhorn Cavern State Park
Fodor's choice
Formed over thousands of years from water cutting and dissolving limestone bedrock, Longhorn Caverns are a fantastic exhibit of Texas natural history. With a history of Comanche tribes seeking refuge in the caves and calcite-crystal beds, the caverns are a perfect destination for families interested in how the limestone caverns in the Hill Country were formed. Be sure to wear rubber-sole shoes; it gets slippery down there.
