This was one of our favorite campsites. The star gazing was some of the best ever, and because of the valley's alignment, you get a fantastic view of both sunset and sunrise. The cost of access is almost ludicrously low, and we were more than happy to spring for a sled and some wax at the gift shop and spend a few hours careening down the dunes.
We were enchanted by the Historic Tour. This was one of our top experiences with our heroes in khaki. The history of the cave, from military asset to World Heritage site, is incredible. We just came to see "a hole in the ground", and came back out adventurers.
