El Camino del Diablo

The bones scattered along El Camino del Diablo tell the real story of this 200-mile desert crossing through Arizona’s Sonoran wasteland. Spanish conquistadors named it “The Devil’s Highway” for good reason—this ancient route from Yuma to Tucson has claimed more lives than any other trail in North America. Today’s overlanders still find century-old grave markers and remnants of failed crossings, reminders that the desert doesn’t care about your schedule or your ego.

This extreme-rated overland route demands a high-clearance 4WD with comprehensive recovery gear, spare parts, and enough water for four people for a week—even if you’re traveling solo. The 200-mile stretch crosses deep sand washes, rocky bajadas, and stretches where a breakdown means a potential rescue situation. You’ll need permits from the U.S. Fish and Wildlife Service to cross Cabeza Prieta National Wildlife Refuge, and cell service doesn’t exist for the entire route. The trail gains 1,800 feet elevation to a maximum of 2,400 feet, but it’s the soft sand and remote location that kills rigs, not the climbs. Plan three to five days minimum, and carry recovery boards, extra fuel, and a satellite communicator—this isn’t negotiable.

November through March offers the only survivable window for attempting El Camino del Diablo, when daytime temperatures drop below the lethal range. Even then, you’ll encounter historic sites like Tinajas Altas, where ancient water holes saved some travelers and became graveyards for others. The trail passes through Organ Pipe Cactus National Monument’s backcountry, where dispersed camping is allowed but water sources remain scarce and unreliable. Every major wash crossing and navigation point has claimed vehicles—GPS and paper maps are mandatory, as are multiple forms of communication equipment.

You don’t run El Camino del Diablo for Instagram photos or weekend thrills. This trail strips away pretense and tests every system in your rig and your preparedness as an overlander. Success means experiencing one of North America’s most remote and historically significant desert crossings while understanding why it earned its deadly reputation. Failure means joining the long list of those who underestimated the Sonoran Desert’s ability to humble anyone who enters unprepared.
