Moab to Claremont: Epic Road Trip Guide Through Utah & California

Moab, Utah sits at 4,000 feet elevation, while Claremont, California rests at 1,168 feet. The 650-mile drive descends through red rock canyons, crosses the Colorado River, and traverses the Mojave Desert. One of the most striking geological features along this route is the San Rafael Swell, a massive 80-mile-long anticline visible from Interstate 70.

I-15 through Nevada has long straight stretches conducive to driver fatigue. Use rest areas every 2 hours. The Salt Flats Rest Area (mile 300) has clean facilities. Between Las Vegas and Barstow, the Baker Rest Area includes a 24-hour restaurant. For families, the Mesquite Museum (Mesquite, NV) features dinosaur exhibits. The Clark County Heritage Museum (Henderson, NV) has historic buildings. Pet-friendly stops: Valley of Fire State Park (pet-friendly trails) and the Mojave National Preserve (leashed pets allowed).

• Fatigue management: Set cruise control at 75 mph. Avoid driving between 2-5 PM on summer afternoons when heat peaks.
• Child-friendly: The Las Vegas Natural History Museum and the Springs Preserve. In Barstow, the California Route 66 Museum.
• Pet relief: Rest areas on I-15 have designated pet areas, but some are unshaded. Best: Baker Rest Area (shade, grass).

Leaving Moab, you'll pass through Arches National Park's edge and the Colorado River gorge. US-191 offers views of red rock buttes and the La Sal Mountains. At Green River, the landscape shifts to gray-green shale badlands. I-70 crosses the San Rafael Swell, a 80-mile anticline with exposed Jurassic sandstone. Near Salina, you intersect I-15 amid volcanic black cinders and juniper forests. The descent into Cedar City reveals the Hurricane Cliffs, a Pine Valley laccolith. Approaching St. George, red sandstone reappears. Crossing into Nevada, the terrain becomes vast Mojave Desert—Joshua trees and creosote scrub dominate. Las Vegas oasis contrasts starkly. The final stretch through the Cajon Pass drops into the San Gabriel Valley, with Mount San Antonio (10,064 ft) rising to the north.

Local commerce along the route: Hoover Dam (Boulder City) offers tours. In Jean, Nevada, the world's largest Chevron sign. In Barstow, the Route 66 Mother Road Museum. In Claremont, the Claremont Packing House is a historic citrus packing facility turned food hall.

The primary route from Moab to Claremont follows US-191 south to I-70 west, then I-15 south through Nevada to California. Total driving time without stops is about 11 hours. Fuel is readily available every 50-80 miles, but prices spike in remote areas. Expect gas to cost $0.20-$0.50 more per gallon in places like Green River and Salina compared to Las Vegas.
