Skyline Caverns is the largest and only developed cavern in Warren County and one of only a few places on earth where delicate and unique formations known as Anthodites are on display. Every year between eighty and one hundred thousand wide-eyed tourists visit the caverns. They are guided through, many for the first time underground, by a staff of knowledgeable and well-trained guides. Many school groups consider Skyline Caverns to be a very educational destination.
