  • This was a fun stop to make in the way to our destination. The gift shop is extensive and they sell interesting things. The outdoor picnic area is available for use and it is clean. The tour was interesting enough, I liked the history. It seemed a bit restricted from the majority of the cave though. I am still waiting for my card to be credited back from a transaction that was supposed to be refunded so hopefully that goes through soon.
  • Very interesting attraction that you should check out. It's an hour tour and it goes pretty deep but it's fun and educational with the help of a tour guide. Also some decent prices and selection at the gift shop.
