Have camped here a couple of times. Usually after discovering that GV campground is full. Lot of room for whatever you have. Tent/RV/trailer. The stars are intense, milky way horizon to horizon! Very quiet. More access points down Goblin Valley Rd.
This is a cool wilderness area. It is state land in between BLM land. This is an area between the Temple Mt. Campground East and the Temple Mt Campground a few miles NW. We reconned up and down Temple Mt rd. and the campgrounds. The dispersed camping seemed to be the best option for us. The two CG's in the area do have pit toilets but that seems to be the only plus. The East CG is super open and seemed like a staging area. The other CG had some ruins but was also open with no cover. We found a little space on the northeast side of the road back in a canyon that was nice. Only bad thing were the gnats. Last part of May and early part of June apparently is a bad time for gnats in the Utah desert.
There are quite a few spots on either side of the road that are kind of established with fire rings made from rock that people have put together. You can scramble over the rocks and hike through the washes. Some attractions near by are the pictograph panel, Temple Mt. ,Wild Horse Window, and Goblin Valley SP. There are also antelope in the area. This is a good place to stage out of if you can't get a spot in the Goblin Valley CG. Remember there is no trash bins so pack it in and pack it out. Bury your poop.
