Pierce County Discovery Area

Crystal Cave


Discovered in 1881, Crystal Cave opened to the public in 1942, with some 4000 visitors showing up on opening weekend. Crystal Cave is Wisconsin’s longest, with about 4600 feet of passages. Located on the northern edge of the Driftless Area, Crystal Cave lies within dolomite (containing calcium and magnesium carbonate) and features iron ore, flint, and quartz crystals. Exhibits underground and on the property outside educate about geologic periods, as well as the fossils and bats of Crystal Cave. There is an 18 hole educational dinosaur minigolf course and gem panning. Ecology efforts extend to the surface, where a seven-acre field near the property entrance has been developed as a pollinator prairie in partnership with the Wisconsin DNR and U.S. Fish and Wildlife Service. Four electric vehicle charging stations available. Adventurous visitors can make reservations to take a three-hour wild cave trip through South Portal Cave.
