After 14 years of living in Arizona, I finally visit Kartchner Caverns. Located in the South near Benson. This is a living cave system and is still changing and growing. The Big Room closed on April 15 for the Summer (so the cave bats can give birth) so I decided to go on April 13. I also took the Rotunda and Throne Rooms tour. With 98% humidity, my skin was moist. Unfortunately you can't take a camera inside so no cool pictures of stalactites or stalagmites. Excellent journey and I highly recommend it.
