Arizona has its fair share of dangerous roads, but none quite compare to El Camino del Diablo. This middle-of-nowhere road in the vast, remote Sonoran Desert dates back at least 1,000 years — and claimed the lives of hundreds, if not thousands, during its heyday.

Way down south near the border with Mexico, this 250-mile road traverses some of the driest, most remote landscape in all of Arizona. Named “El Camino del Diablo,” or “The Devil’s Highway,” the treacherous thoroughfare has claimed up to 2,000 lives due to dehydration, heat stroke, sunburn, and hyperthermia.

Native Americans began traveling along the road at least 1,000 years ago. Between the 16th and 19th centuries, it was used by conquistadores, explorers, missionaries, settlers, miners, and cartographers.

The original route began in what is now the Mexican state of Sonora. It continued north into Yuma Crossing, a point from which travelers could cross the Colorado Desert into the Spanish colonies of California.

Most of the graves lie in the final 30 miles of the road. Summer temperatures can reach up to 120 degrees Fahrenheit, a level of heat that demands two gallons of water for each person just to ensure survival.

Today, the highway has largely disappeared south of the Mexico-U.S. border. The current route begins just southwest of Ajo, between Organ Pipe Cactus National Monument and Cabeza Prieta National Wildlife Refuge.

At this point, travelers will encounter a fork in the road. A shortcut leads through the Barry M. Goldwater Air Force Range, while a longer route – which parallels the original highway more closely – culminates in the unincorporated community of Fortuna Foothills, Arizona.

A permit from the Cabeza Prieta National Wildlife Refuge office in Ajo is required to traverse the Devil’s Highway.
