Halfway between Kingman and Bullhead City, on the western side of the pass, is this BLM land that will knock your socks off!  Many places to pull over for a night or for a week or two along the road. No services, no water, no toilets, just beautiful open desert with quintessential AZ mountains. Closest towns with supplies are Kingman and Bullhead City, about 20-30 minutes from each.
