El Camino del Diablo (The Road of the Devil) is a rough, unpaved route crossing the Barry M. Goldwater Range in southwestern Arizona. Beginning in 1849, between 400 and 2,000 people died of thirst along the trail, making the Camino the deadliest immigrant trail in North America. Today's visitors travel through natural landscapes with scenery ranging from the desert mountain ranges of the Gila and Tinajas Altas Mountains, to the low desert and sand dunes of the Yuma
and Lechuguilla Deserts. A US Marine Corps permit is required for entry, available from the Marine Corps Air Station, Yuma, Range Management Department. The byway continues through the Cabeza Prieta National Wildlife Refuge. A permit from the US Fish and Wildlife Service is required to travel on the refuge. There are no services, water or facilities along this route. Four-wheel drive is recommended on all routes on the Barry M. Goldwater Range. Please call to inquire about road conditions.
