Self-Guided Cave Tours
Entry into the cavern is by way of two different self-guided routes—the Big Room Route and the Natural Entrance Route. The Natural Entrance Route is a steep, 1.25 mile, 750 foot descent down switchbacks into the cave. This entrance is not wheelchair accessible. The Big Room Route allows for wheelchairs in the areas that are not steep ascents/descents (certain inaccessible areas have pinch points). Tickets are sold at the visitor center each day, except Thanksgiving, Christmas and New Year's Day. Entrance fee tickets are good for three days, but do not include guided or other special tours. Summer hours are in effect from Memorial Day through Labor Day.
Sept - May ~ Big Room Hours (for entry): 8:30 a.m. to 3:30 p.m.
