Easy destination to find with our rental car and my google map app on my i phone. Very nice buildings and gift shop. Guide was very nice and knew her stuff. The cave was very hot even though the temp was only 70 the humidity made it feel like 85. I had to bail on the tour very quickly as I am claustrophobic, however my husband and friends enjoyed the tour very much while I waited outside. Incredible these were only discovered in the early sixties.
