I've been here a few times on field trips, and this place is pretty neat, though it's not that impressive if you've been to larger caves other places. It's pretty out of the way, and generally the only people that go are schools and church groups. They have a tour which takes you around the place and points out interesting rock formations. It is however, basically nothing more than a giant hole in the ground, so if you're not into spelunking, give it a pass. Can be educational for kids though.
