What a beautiful cave, truly wonderful! This is a great place to take kids and see Earth's inner beauty. The climb to the cave is a hike, but worth it. The cave is very clean and easy to navigate the well lit paths. Tour guide was very knowledgeable and friendly. After visiting the cave there is a miniature golf course, a nature walk, a gift shop, and a place to eat. To get to this location is a bit of a hike and in the middle of nowhere, but relatively close to Allentown PA. Overall, this is a small cave, but really great to check out if you are in the Allentown/Bethlehem PA area.
