The State College area has a number of caves that you can visit, and Indian Caverns should be on your "must see" list. The tour is about an hour and the guide is very informative about the history of the cave (some of which is very funny) and the geology of the cave. Even if you might have been to other caves in the area Indian Caverns is worth seeing because no two caves are alike. We will be back in the fall with a Boy Scout Troop when we will sleepover in the cave and the boys will also work on merit badges offered by the staff. Where else can you have an outing like that!
