El Camino del Diablo is the clearest case in Arizona. It needs a permit for every adult, four-wheel drive with high clearance, two spare tires, two gallons of water per person per day, and it crosses an active military range and 93 percent wilderness with no services and no cell reception for 72 miles.
Toroweap is the second. Permits must be bought at least five days ahead and cannot be issued on site, mud driving is prohibited, and the road is 61 miles of sharp rock. Commercial guiding on federal land needs its own permit, so ask whether a guide holds one.
A guide earns the fee in the places where the map runs out of detail. They know which wash flooded last week, which gate is locked, where the fuel is, and how long the hard section really takes with a group.
A guided trip usually brings
01Route knowledge and current conditions
02Permits and access already arranged
03Recovery skill and equipment
04A pace that suits the group
05The history and natural history of the place
How to choose a guide
Ask the questions a land manager would.
01Ask whether they hold the permits and insurance required to operate commercially on the land they use.
02Ask about group size and the minimum vehicle requirements.
03Ask what is included: meals, camping gear, communications, a support vehicle.
04Ask about first-aid training and the plan for emergencies.
What to tell a guide
Honesty about experience makes for a better trip.
01Your vehicle and what has been done to it
02Your experience off pavement
03Who is coming, including children and dogs
04Your dates, and what you most want to see
Questions people ask
Do I need a guide?
Not for most travel. A guide earns the fee on routes that are remote, technical or hard to get permits for, and on first trips where you would rather learn than guess.
Can I join a guided trip in my own vehicle?
That is how most overland guiding works. The guide leads in their vehicle, you drive yours, and the trip sets minimum requirements for the vehicles that come.
How high is Arizona?
From Yuma at 141 feet to Humphreys Peak at 12,633.
Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.
