Good family outing
Worth the trip, Very cool part of Earth.
Its not spectacular, but it is cool especially if you like science and you want to do something different. It's quaint and has a local vibe to it if you are into that. Its family owned and operated. The cost is very fair. It think $8 per person fo the tour. It's not far from Bethlehem, its in Hellertown, but I'm sure Google maps could give you the specifics.
I stopped here with my gf a few months ago. I think it was around $20- $30 for both of us. The tour of the cave is around a half hour. It's nothing spectacular, but it's something different to check out once.
What time is last tour for the day
