Summers are dry statewide. NOAA calls the southern deserts some of the nation’s hottest and driest areas
When a guide is the right call
The case is strongest where the road is committing or the consequences are slow. Titus Canyon is one way from east to west, so once you start there is no turning back, and the Park Service recommends not driving the Mojave Road alone and traveling in a group of two or more four-wheel drives on rough remote roads.
A guide is also worth it for timing. The desert and the Sierra swap seasons, several roads are day use only, and a local knows which of the five hundred miles of Anza-Borrego dirt suits the vehicle you actually brought.
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 California?
From Brawley at -113 feet to Mount Whitney at 14,494.
Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.
