You step off the sun-warmed parking lot and into shade; the limestone slope dips beneath your feet as guides call groups to the visitor center. The descent begins—126 steps that ferry you away from the Texas Hill Country’s scrub live oak and into a steady, cool 66°F. Lighted walkways thread through vaulted rooms, and formations reach toward you like slow-moving sculptures: soda straws, drapery, rimstone dams and columns that took millennia to arrive.
