We stayed in group campground G01, which is the one closest to the road. It was spacious and offered 2 sheltered picnic areas and 2 fire pits, and was a short jaunt (crossing the next campground) to the restrooms (which had flush toilets!). It was a definite bonus to have running water as well! G01 is situated in a way that tents can be spread out and as communal or as secluded as you'd like (not counting the road). The campground is close to hiking and the Twin Palms Oasis loop is nearby as well! Be aware that this campground is NOT near the large rock formations in J.Tree but it is very convenient for large groups :)
