Safford to Santa Monica: Desert Drives & Coast Views

This route crosses the Gila River near Safford, then climbs through the Pinaleño Mountains before descending into the Sonoran Desert. The drive covers 570 miles and takes about 9 hours without stops.

The journey ends at the Santa Monica Pier, where Route 66's western terminus marker stands. Along the way, you'll traverse three distinct climate zones: arid highlands, low desert, and coastal Mediterranean.

Fuel economy is critical. Gas prices drop about $0.50 per gallon in Arizona versus California, so fill up before crossing the border. Expect 4-5 fuel stops for a typical sedan.

Cell service is spotty between Safford and Phoenix on US-70 and US-60. Download offline maps before departure. Restrooms are available at most gas stations, but few are open 24 hours.

• Route: US-70 to US-60, I-10 to CA-60, I-10 to CA-1
• Toll roads: None on this route
• Major cities: Phoenix, Indio, Riverside, Los Angeles
• Weather: Monsoon thunderstorms possible July-September; coastal fog in the morning

Road surface quality is good on interstates, but sections of US-60 east of Phoenix are two-lane with limited shoulders. In California, expect heavy traffic from Riverside to Santa Monica during weekday rush hours.

South of Safford, the Pinaleño Mountains (also known as Mount Graham) reach 10,720 feet, supporting alpine forests that contrast sharply with the desert below. The area is a biodiversity hotspot with several endemic species.

As you descend into the Sonoran Desert, saguaro cacti dominate, particularly around Picacho Peak. The desert blooms with wildflowers in March, but summer temperatures exceed 110°F, making dawn driving essential.

Beyond the botanical appeal, the landscape shifts to the Colorado Desert near Indio, where date palms line the coachella valley. The San Andreas Fault runs parallel to I-10 for miles, visible as a linear valley.

Local commerce along the route includes the Safford farmers' market on Saturdays (call ahead for seasonal hours). Phoenix's historic downtown offers art galleries and Indigenous cultural centers, while Indio's date shakes are a regional specialty.

In the San Gabriel Mountains near Los Angeles, the route passes near the San Antonio Winery, founded in 1917 and still operating. This area also hosts the annual LA County Fair in spring.

Desert driving demands hydration: carry 1 gallon per person. The average driver on this route should stop every 2 hours or 100 miles; recommended rest areas include the Copper Mountain Rest Area (mile 213), the Hassayampa Rest Area (mile 174), and the Indio Rest Area (mile 97).

For families, the Arizona Science Center in Phoenix offers hands-on exhibits. The Living Desert Zoo in Palm Springs is a pet-friendly stop (on-leash) with a giraffe feeding area. Santa Monica Pier has a solar-powered Ferris wheel and an aquarium.

Fatigue signs include lane drifting and yawning. Consider an overnight rest in Phoenix, where hotels average $120/night and have 24-hour check-in.

Road quality on I-10 is excellent except the pavement around the San Bernardino Mountains, which has expansion joints that vibrate the steering wheel. In the Coachella Valley, crosswinds can exceed 40 mph during windy season (March-April), so secure roof cargo.

Hidden off-route gems: the Sonny Bono Salton Sea National Wildlife Refuge (exit 95) offers birdwatching from late fall to early spring, and the ghost town of Calico near Barstow is 30 minutes north of I-15 (not on the main route).

For unique local culture, visit the Safford Underground Railroad site (only a historical marker) or the Meteor Crater near Winslow (80 miles north of I-40, off-route). These are best visited on a longer itinerary.
