El Camino del Diablo
Death's highway through the Sonoran—no cell, no mercy.
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.

Frequently asked questions
Can a stock Tacoma or 4Runner handle El Camino del Diablo?
Only if it's a true high-clearance 4WD with a locking differential and you're running aired-down tires — stock street pressure in deep Sonoran sand will bury you. A lift helps but isn't mandatory; recovery gear (traction boards, hi-lift, snatch block, tow strap) is non-negotiable on a 200-mile route with zero rescue infrastructure.
When does the trail actually close, and what happens if you go in summer?
The trail isn't formally gated shut, but the Cabeza Prieta NWR permit system strongly discourages travel outside November through March. Summer temps regularly hit 115°F+, shade doesn't exist, and people die out here — this isn't hyperbole, the route is littered with historical grave markers for a reason.
What permits do you need and how far in advance should you get them?
You need a free permit from Cabeza Prieta National Wildlife Refuge (fws.gov/refuge/cabeza-prieta) plus a signed Military Hold Harmless Agreement because the route crosses the Barry M. Goldwater Air Force Range. Get both before you leave — rangers do check, and you cannot obtain them trailside.
What's the hardest section and what makes it brutal?
The deep sand stretches west of Tule Well are where most rigs get stuck — long, loose, washboard-broken sand with no firm base and no bailout. Plan for slow, grinding mileage (think 10-15 mph), constant throttle management, and the psychological grind of knowing a breakdown here means a very long wait for help that may not come quickly.
How much water and fuel do you actually need for this route?
Carry a minimum of 5 gallons of water per person for the full run — there is zero reliable water on route and temperatures can spike even in winter. Fuel range is critical: the route is roughly 200 miles point-to-point with no gas stops, so carry enough jerry cans to cover your rig's consumption in low-gear sand driving, which drinks fuel fast.
