How to choose
Choose Hancock Springs for a close, seasonal swim; Longhorn Cavern for a park-centered guided tour with several formats; and Inner Space for a standard show-cave outing in Georgetown. None is interchangeable, and each has its own accessibility, season, and ticket rules.
Colorado Bend also has concessionaire-run wild cave tours, but its Discovery Tour was unavailable during research because vultures were nesting at the entrance. Do not promise that specific tour without checking cbcaves.com.
