Cedar City to Manhattan Beach Road Trip: Epic Desert to Coast Journey

This 600-mile journey from Cedar City, Utah, to Manhattan Beach, California, traverses three distinct states, crossing the Great Basin, the Mojave Desert, and the Los Angeles Basin. The route primarily follows I-15 South and I-10 West, a corridor that links high desert plains to coastal urbanity.

A little-known fact: Cedar City sits at 5,840 feet elevation, while Manhattan Beach is at 66 feet. Over the drive, you descend more than a mile in altitude, crossing the mighty San Andreas Fault near Cajon Pass. The stark contrast between Utah’s red rock and California’s palm-lined beaches defines this journey.

The backbone of this trip is Interstate 15 from Cedar City to Barstow, then Interstate 10 into Los Angeles. Exit 0 in Manhattan Beach is a 23-mile stretch on the 105 Freeway.

• Fuel Stops: Key fuel-up points include St. George, UT; Mesquite, NV; Las Vegas, NV; and Barstow, CA. Expect prices to rise near the coast.
• Tolls: No tolls on I-15 or I-10 except for express lanes near downtown LA (optional).
• Coordinate Milestones: 37.6775° N, 113.0611° W (Cedar City) to 33.8867° N, 118.4108° W (Manhattan Beach).

An average fuel economy of 25 mpg means roughly 24 gallons of gas for the 600-mile trip. At $4.00/gallon, you’ll spend about $96 on fuel. For an EV, plan charging stops in St. George, Las Vegas, and Barstow.

• Route Economics: Gas is cheapest in Utah (often $3.50/gal) and priciest in California ($5.00+/gal). Fill up before crossing the state line.
• Rest Stops: Official rest areas near Littlefield, AZ (milepost 8 on I-15) and Baker, CA (I-15). Open 24/7 with picnic tables.

From cedar forests to Joshua trees, the scenery transforms dramatically. Near Cedar City, the red rock of Kolob Canyons (part of Zion National Park) is visible from the highway. As you approach Las Vegas, the Mojave Desert opens up, filled with creosote bushes and yucca.

• UNESCO World Heritage Sites: Zion National Park (about 1 hour detour) is a UNESCO site. Also, nearby Grand Canyon (South Rim, 3 hours detour) is a must-see.
• Hidden Off-Route Gems: Valley of Fire State Park, NV (east of I-15, exit 75) features red sandstone formations. Calico Ghost Town near Barstow offers a preserved mining town.

Local commerce thrives along the route. In St. George, visit the historic downtown for Utah souvenirs. In Barstow, sample date shakes from China Ranch Date Farm. As you near Los Angeles, strip malls give way to taco trucks.
