This is a BLM (Bureau of Land Management) site. The visitor centre has a large shop and the help desk is very helpful. He suggested that we stop off at Calico I & Calico II, then at Sandstone Quarry take the Calico Tanks walk which was a medium grade walk over a lot of rocks and there were a few places that you had to scramble on your hands (4 km) – we could see Las Vegas in the distance at the end. The campground is a kilometre away from the park and it’s very basic, very open and when we were there, very windy. Not a nice place to be during the day – wind or no wind.
The road to see the sights is a one way loop, so you can't change your mind and go back to a trail you may have missed.
