It is $45 per night to camp at goblin Valley State Park and the free spots to the west of the park are so much better and they are free! We found a great spot with a little hidden canyon that our son put his tent in. We went in the middle of October and it was 40° at night and 75° during the day so we were pretty cold at night but pretty hot during the day. We have a Toyota sienna minivan with front wheel drive and the dirt roads to the campsites were totally passable for us, just go slow
