Goblin Valley State Park (about 30 miles from I-70, south at exit 149)
Note from user Travelingman: Goblin Valley is a wondrous park but it is pretty much in the middle of nowhere. If all of their campsites are full when you arrive, which happened to me, there is an alternative.
There is a large dispersed BLM camping area on Temple Mountain Road just past Goblin Valley Road. You can see it clearly on a map with satellite view. Quite a few RVs were there. I don’t recall there being anything other than a dirt parking lot but it will do if you’re self contained.
Of course, other people were simply setting up camp by themselves in the desert, but my wife didn’t feel safe without others camping nearby.
