Laurel Caverns is a large sandstone cave located 50 miles south of Pittsburgh. This is the largest cave in Pennsylvania where most of the passage ceilings are between 10- and 20-feet high to as high as 50-feet with an average width of over 12 feet! Situated beneath a 435-acre geological preserve at the top of Chestnut Ridge means all water entering the cave is pristine. Preservation and maintaining the cave is funded by cave admissions, program admissions, and their gift shop. Laurel Caverns also entertains the largest natural bat hibernaculum in Pennsylvania and is closed November through April during the primary months of the bat hibernation season. May through October the cave is usually devoid of bats.
