Moab to Hermosa Beach Road Trip Guide

The 750-mile journey from Moab, Utah to Hermosa Beach, California traverses the Colorado Plateau, passes the Great Basin, and ends at the Pacific Coast. A little-known fact: the stretch of I-15 through the Virgin River Gorge near the Utah/Arizona border is one of the most expensive interstate segments ever built per mile due to the rugged terrain. Estimated driving time is 11 hours without stops, but plan for 2-3 days to explore.

This guide covers everything from fuel economics to family-friendly stops. Use the how to find the best stops and hidden gems between cities resource to customize your trip.

Road safety considerations: Deer and livestock crossing on rural highways (especially at dusk), sudden crosswinds on I-70 near the Sevier River, and frequent dust storms in the Mojave. In winter, I-15 can close due to snow at Cajon Pass (elevation 4,800 ft). Carry chains from October to April.

• Fatigue management: Take breaks every 2 hours or 150 miles. Use rest areas: Green River (mile 145), Meadow (mile 48 of I-15), Baker (mile 226 of I-15).
• Family suitability: Stop at the Kolob Canyons Visitor Center (free, kid-friendly films) and the Las Vegas Natural History Museum (dinosaur exhibits).
• Pet-friendly framework: Most national parks allow leashed dogs on paved trails. Off-leash areas at Snow Canyon's Red Mountain Trail (open area) and Hermosa Beach's dog beach (south of pier).

Hidden off-route spots: Valley of Fire State Park (1 hour north of Las Vegas, $10 entry) offers red sandstone trails with ancient petroglyphs. Near Barstow, the Calico Ghost Town (old mining town, fee $8) has fun gold panning. For a quiet coastal escape before Hermosa Beach, visit Bolsa Chica Ecological Reserve in Huntington Beach (free, boardwalk over wetlands).

Culinary infrastructure: From Moab's famous Moab Brewery (gourmet pub food) to St. George's Pizza Factory (family-friendly), to Las Vegas' myriad buffets (try Bacchanal at Caesars, $70/person). For budget bites, the Del Taco on I-15 in Baker is a reliable cheap option. In Hermosa Beach, grab fish tacos at Baja Sharkeez on the pier.

Local culture along the route: The annual Moab Folk Festival (September) and the St. George Art Festival (October) showcase regional talent. In Las Vegas, the Neon Museum exhibits historic signs. Hermosa Beach's farmers market (Fridays) features local produce and crafts.

The drive showcases dramatic transitions: from red rock arches near Moab to the black lava fields of Cinder Cones Natural Area, then the green valleys of Utah's Dixie and finally the coastal sage scrub of Southern California. Each region offers distinct natural attractions and local commerce opportunities.

• Natural Bridges National Monument (detour 20 mi south of Blanding): Ancient sandstone bridges and Dark Sky Park.
• Goblin Valley State Park (near Hanksville): Hoodoos and mushroom-shaped rock formations; $20 entry fee.
• Cedar Breaks National Monument (near I-15, Cedar City): Alpine cirque of vibrant hoodoos; elevation 10,000 ft.
• Snow Canyon State Park (St. George): Hiking among red and white sandstone; pet-friendly trails.
• Mojave National Preserve (near Baker, CA): Joshua trees, sand dunes, and abandoned Kelso Depot.

UNESCO World Heritage Sites: The route passes no UNESCO site directly, but a 2-hour detour from Salina leads to Capitol Reef National Park (not UNESCO) or a 3-hour detour from St. George to Grand Canyon National Park (World Heritage). Alternatively, from Barstow, a 4-hour detour takes you to Yosemite National Park (World Heritage). For this trip, the most accessible UNESCO site is the Grand Canyon via US-89A from Fredonia, AZ (adds 2 hours each way).

Local commerce thrives in small towns like Springdale (near Zion, but off route) and along the main streets of St. George and Las Vegas. Look for farm stands selling Utah peaches near Brigham City (in season) and Silver State gifts in Nevada. The outlet mall in Primm, NV at the California border offers tax-free shopping.

The route primarily follows US-191 south from Moab to I-70 west, then I-15 south through Utah and Nevada into California, ending on CA-1 and CA-91. Road quality is excellent on interstates, but watch for construction near Las Vegas and through Cajon Pass. Fuel stations are plentiful every 30–50 miles on main highways, but sparse in remote stretches like between Green River and Salina.

• US-191: 2 lanes, speed limit 65 mph, scenic but winding through canyons.
• I-70: 4 lanes across Utah high desert, high winds possible near Cove Fort.
• I-15: 4–6 lanes through Utah and Nevada, heavy traffic in Las Vegas metro area.
• CA-91: 6–8 lanes, notorious for rush hour congestion near Long Beach.

Fuel prices vary significantly. In Moab, expect $4.00–$4.50/gal. Drop to $3.50 in St. George, spike in remote Nevada towns (up to $5.00), then lower again in California's inland areas ($4.00–$4.50). Consider filling up in Utah's larger towns.

1. Moab: Chevron and Marathon stations on Main Street.
2. Green River: Limited options; fill up before leaving Moab.
3. Salina: Multiple stations near I-70 exits.
4. St. George: Abundant, cheapest along I-15 corridor.
5. Las Vegas: Gas can be cheaper off-strip; avoid stations near The Strip.
6. Barstow: Costco and other discount fuel available.
