My wife and I planned a return to Joshua Tree earlier this year and booked at this campground. We did not know the campground, and were surprised when we learned that it is basically "outside" the park, since it in the very north part of the park, and to get to the main sites in the park, you must depart the campground, drive 5 miles to the main road, drive to the Joshua Tree entrance and then re-enter the park, which is a little disappointing.
The park itself is a nice desert park, and the big plus here is running water. There are some trails here, but we were too tired to try them after doing some other hikes. We had campsite 23, which on the map looks like it is toward the edge of the camp. We had expected some noise / quiet benefits from that location, but unfortunately, on Friday night, it seemed that there were about 5+ tents of drunken millenials just across the way, who yelled, played music and debated the merits of Jack Johnson until about 1 in the morning. I can't imagine that anyone within 100 yards of these people got a decent night sleep, and there was no evidence of Park Rangers trying to keep these people civil. I told my wife that I could not do another night, but she convinced me to do some hiking on Saturday and come back and then decide if we pack up. When we returned to the site, all the millenials had packed up and left, and although I could see from the reservation board that they booked 2 nights, I guess they could not deal with the cold and left, thankfully.
Our sleep on the second night is how I remember camping to be. Mostly quiet, you hear people even very late, but there are few and not obnoxious, and seemed to show some respect for those sleeping.
Would I stay here again? Yes, but I am definitely going to have earplugs, and I am going to ask the Rangers when I see them on their policy on late night noise.
