We were trying to find a place to sleep for the night and this worked, but the road was in really rough shape. We had to take it very slowly so it took about an hour to find an established site. We didn't make it all the way to the arch because that "road" was mostly giant rocks and we were renting our campervan. We drove past that turn and found a spot at 10:30pm. We woke up to the most amazing views! What a beautiful area, I wish we'd had more time to explore!
