More than 3,000 caves are scattered throughout Texas, including many that are wild or undeveloped. But for experiences everyone can enjoy, the best options are Texas's popular "show" caves: Natural Bridge Caverns, Longhorn Cavern, Inner Space Cavern, Cascade Caverns, Caverns of Sonora, Wonder World Park, and Cave without a Name.
