Blanding to Santa Monica Road Trip Guide: Epic Southwest Drive

This route traverses over 700 miles of dramatic elevation change—from Blanding, Utah at 6,100 feet to Santa Monica at sea level. You'll descend through the Colorado Plateau, cross the Mojave Desert, and reach the Pacific Coast. The driving time is roughly 11–12 hours without stops, but the journey deserves several days.

A little-known fact: the stretch from Blanding to Hanksville (UT-95) passes through the Glen Canyon National Recreation Area, where the Colorado River carved canyons that predate the Grand Canyon. This road was constructed in the 1960s as part of the Lake Powell access infrastructure.

This guide is structured to help you navigate every aspect of the trip. For more on finding unique stops, see how to find the best stops and hidden gems between cities.

Infrastructure Safety & Road Quality

I-70 and I-15 are in good condition, but remote stretches (especially between Salina and St. George) have long intervals between services. Watch for wildlife: deer, elk, and even bighorn sheep in canyon areas. In the Mojave, strong crosswinds can affect high-profile vehicles.

• Carry emergency water (1 gallon per person) and a spare tire.
• Cell coverage: Verizon works best; AT&T and T-Mobile have dead zones near the Utah-Nevada border.
• Law enforcement: Strict speed limits (80 mph max on I-15 in parts of Utah).

Family and Child Suitability

Entertainment stops include the Moab Giants dinosaur park (life-sized replicas) and the Las Vegas Discovery Children's Museum. Natural arches and rock formations appeal to children who like climbing (with supervision). Rest stops often have playgrounds.

• Moab: Children's art classes at Moab Arts Center.
• St. George: St. George Children's Museum.
• Los Angeles: Santa Monica Pier aquarium.
• Consider audiobooks or travel games for the long drive.

Pet-Friendly Framework

Most motels along the interstates accept pets (Super 8, Motel 6). National parks generally allow dogs on paved roads and in campgrounds, but not on trails. Rest areas have designated pet relief areas, though few have fully fenced runs.

• Accommodations: Best Western in Blanding and Moab are pet-friendly.
• Veterinary: Emergency clinics in Moab, St. George, and Las Vegas.
• Hydration: Always have a collapsible bowl and extra water for your pet.

Fatigue Management & Rest Zones

Drive no more than 4 hours without a 15-minute break. Ideal rest stops: Cove Fort rest area (historical site on I-70), Baker, NV (home of the World's Tallest Thermometer), and the Victorville rest stop (clean with shade). If drowsy, pull into a designated rest area or truck stop—never the shoulder.

• Rest stops with amenities: Scipio (clean restrooms), Beaver (tourist info), St. George (gas and food).
• Sleep options: Blanding: Prospector Inn; Beaver: Best Western; Barstow: Days Inn.
• Per mile: The average cost of lodging is ~$100/night for budget chains.

Beyond these practicalities, remember that the journey between Blanding, UT and Santa Monica, CA is as rewarding as the destination. The question of is it worth driving is answered by the profound transitions in landscape and culture. For a deeper dive into planning, refer to our guide on how to find the best stops and hidden gems between cities.

Start on UT-95 west from Blanding, then merge onto US-191 north toward Moab. From Moab, take I-70 west through the San Rafael Swell. Near Salina, switch to I-15 south toward Las Vegas. Finally, I-15 south becomes I-10 west into Santa Monica. The highways are well-maintained, but cell service is spotty in remote areas.

Fuel and Route Economics

• Fuel stops: Blanding (last cheap gas for a while), Moab, Salina, Beaver, St. George, Las Vegas. Prices increase in remote areas—fill up in larger towns.
• Cost: At 25 mpg and $3.50/gal, fuel cost around $100 one-way. Consider an electric vehicle only if you plan charging at Moab, Salina, St. George, and Las Vegas.
• Time-saving: Avoid unnecessary deviation by sticking to interstates; but consider a detour via Zion National Park (adds 1 hour).

Climatic Conditions & Route Aesthetics

Blanding in summer averages 90°F, while Mojave heat can exceed 110°F. Snow is possible early spring or late fall on higher passes (I-70 near Salina). Coastal fog near Santa Monica in June can reduce visibility. Best times: May, September, and October for moderate temperatures and clear skies.

• Spring: Wildflowers in Utah deserts, but potential rain in Mojave.
• Summer: Prepare with extra water and air conditioning check. Many attractions run on limited hours due to heat.
• Winter: I-70 may close briefly due to snow. Check weather before leaving.

Culinary Infrastructure

Southwest cuisine dominates: Navajo tacos, green chile stew, and fry bread in Utah. In Las Vegas, endless buffets and gourmet options. California leg features fresh produce stands in Coachella Valley and coastal seafood. Recommended: Moab's Jailhouse Cafe (budget) or Hell's Backbone Grill in Boulder (upscale).

• Breakfast: Home Plate in Blanding (pancakes and eggs).
• Lunch: Eklecticafe in Moab (smoothies and wraps).
• Dinner: In-N-Out in Barstow (California staple).

Natural Landscapes & Attractions

From Blanding, the route passes by Natural Bridges National Monument (detour 20 mins) with massive stone spans. Further west, the San Rafael Swell offers unique geology—a 60-mile anticline visible from I-70. Near the Nevada border, Valley of Fire State Park displays red sandstone formations. The final leg into Los Angeles crosses the San Gabriel Mountains, with views of the Pacific on a clear day.

• Blanding to Moab: Comb Ridge, a 90-mile sandstone monocline.
• Moab to Salina: I-70 through the Book Cliffs and Green River.
• Salina to Las Vegas: Cedar City views of Hurricane Fault.
• Las Vegas to Santa Monica: San Bernardino Mountains and Cajon Pass.

UNESCO World Heritage Sites

While not directly on the route, Mesa Verde National Park (1 hour from Blanding) is a UNESCO site with Ancestral Puebloan cliff dwellings. Also, the Grand Canyon's South Rim is a 3-hour detour south of Page. For the purist, the route's cultural landscape includes outlying Puebloan sites like Hovenweep National Monument.

• Mesa Verde: Visit from Cortez; open year-round.
• Grand Canyon: If time allows, take a day trip from Flagstaff.
• Local commerce: In Moab, small galleries sell Native American pottery and modern art.

Local Commerce & Culture

Moab's economy thrives on tourism. Blanding sees less traffic, but the Edge of Cedars State Park Museum showcases local artifacts. Salina is a agricultural hub, known for its turkey processing. St. George offers Mormon pioneer history. Las Vegas needs no introduction. Santa Monica's Third Street Promenade is a pedestrian mall with street performers.

• Blanding: The Dinosaur Museum, small but educational.
• Moab: Slickrock Bike Trail and Colorado River rafting.
• Salina: The Old Santa Fe Railroad depot.
• Santa Monica: Pier and Palisades Park.

Hidden Off-Route Spots

Just south of I-70 near Green River, the Crystal Geyser is an artificial cold-water geyser. Near Hanksville, the Mars-like terrain of Factory Butte offers surreal photo ops. In Nevada, the ghost town of Rhyolite (near Beatty) is a worthwhile 20-minute detour with preserved ruins.

• Goblin Valley State Park: Full of hoodoos; 20 min off I-70.
• Weepah Spring: Rock art near Moapa Valley.
• Zzyzx: A desert research station on I-15.
