Tinajas Altas Pass Trail Professional Review and Guide
"The original El Camino del Diablo had two possible exits that could be taken, depending on the availability of water and the stamina of the traveler. The rugged west route over Tinajas Altas Pass and the waterless Davis Plain to Yuma is described here. For the well-prepared desert four-wheel driver, this western route combined with the main route over to Ajo is possibly the best, most scenic, and most remote of the trails that follow sections of the original El Camino del Diablo. Combining the two routes will almost certainly require a second night’s camp and a third day on the trail as well as additional fuel.
Although the length is similar to the skipped portion of the main route, the rougher and sandier trail surface is slower going and will use more fuel. Special Attractions: Old Fortuna Mine; Varied trail winding in the Gila Mountains; Panoramic views over the Barry M. Goldwater Air Force Range. High-clearance 4WDs are preferred, but any high-clearance vehicle is acceptable. Expect a rough road surface; mud and sand are possible but will be easily passable. You may encounter rocks up to 6 inches in diameter, a loose road surface, and shelf roads, though these will be wide enough for passing or will have adequate pull-offs."
