No...we spent one night there last May...very quiet, two pull through sites that are isolated from the main area...great for stargazing and night sky photography, short, easy hike takes you past the hundreds of petroglyphs

No, it's first come first served. Most sites are for tents/vans. Only two are suitable for travel trailers and bigger. They both have water/elec hookups. If there are no suitable sites available, they let you park overnight on the far side of the visitor center (at least the hosts did when the visitor center was open). I highly recommended this place. Say hi to Rocky, the tame road runner who lives in the campground.There is a dispersed area somewhere further up the road too. I didn't drive up there, so I don't know what the access is like.

When we were there it was first come first served, self register
