Diamond Caverns is located in Park City, Ky, near Mammoth Cave. But Mammoth Cave is not the only cave worth visiting. Diamond Caverns is a very beautiful cave that has a very long history. The tour was an hour long and well worth the ticket price. Our guide explained the history of the cave to us and answered all of our questions. When we visited the cave was very wet and drippy which is a good thing because that means the cave is still alive and growing. We had a great time and I would highly recommend this tour.
