Cibola Road crosses the Army's Yuma Proving Ground between Highway 95 and the Ehrenberg Cibola Road. Before starting the road, call the Proving Ground at 928 328-2047 for permission to enter. There is signage on the road's eastern end with information about entering the probing ground. The western end does not have signage. The Proving Ground may refer to the road as Cibola Lakes. Permission is granted unless there is a test in the area involving explosives. Do not leave the roadway as the area has not been fully cleared of unexploded ordinance. Thus, there is no camping on the trail.
On the eastern end, the road is wide and well-graded. Midway through, the trail becomes sandy and rough as it follows Mojave Wash through the Trigo Mountains. 4WD is recommended due to the deep sand.
