We stayed at the group site near hamburger rock
We had a group site reservation though Rec.gov but do not use their longitude and latitude for your gps. If you do it will take you onto an Atv trail that looks like a road and is not clearly marked and very dangerous. However that actual campsite was awesome. There was no one for miles and our large group loved that. There is no water in the area and the ony shade was the shelter so it was hot. Its in a canyon area and gave the children alot of area to run and climb.
