.. says the sign when entering the final road to the campground. But we were lucky, no rain before and got in without any issues towing small teardrop trailer. Upper area is flat with grass. A bit exposed to the wind but we were able to set up the trailer to protect it from the gusts of wind. The plateau is pretty large, especially when empty. Our Neighbour’s took the prime spot with a view to the Devils Tower. We enjoyed the place for a night nevertheless, especially when lots of other camp places are still closed for the season.
