One of the few remaining 4x4 trails in the region to access the Price River, Coleman Wash is a moderate drive along a private ranch road and through a rocky canyon. The trail branches off of Grassy Flats, adding an excellent addition to a rather mundane trail. There are a couple of "flexy" washouts in the wash, and large rocks require high-ground clearance and durable tires. Work is being done at a diversion dam for a canal system. The trail conditions may change, and it is impassable in wet conditions. No camping was found along the river or in the canyon.
