Claremont to Orderville Road Trip: Ultimate Guide

Claremont, CA sits at the base of the San Gabriel Mountains. Orderville, UT lies near the heart of Zion Country. The 450-mile route via I-15 N crosses from coastal sage into high desert and then red rock canyons.

Historical fact: The Old Spanish Trail once passed near this corridor, linking Santa Fe to Los Angeles. Modern travelers can trace a similar path along the Mojave.

The drive typically takes 6.5 hours without stops. Plan for 8-10 hours to enjoy attractions.

Fuel stations are plentiful along I-15 but sparse in the Mojave stretch between Barstow and Primm. Fill up in Barstow or Victorville.

Gas prices decrease in Nevada due to lower taxes. Las Vegas has many stations.

• Claremont to Las Vegas: ~$50-$70 in fuel (sedan).
• Las Vegas to Orderville: ~$30-$40.
• Total round-trip fuel cost: $160-$220.

Tolls: No tolls on I-15. Avoid US-95 in California (no tolls, but slower).

I-15 is well-maintained with wide shoulders. Watch for wind gusts near the Mojave wind farms. Summer heat can cause overheating; check coolant.

Rest areas every 50-70 miles. Notable: Barstow Rest Area, Primm Rest Area with gas and food.

• Family stops: Las Vegas has the Discovery Children's Museum. Mesquite has a water park.
• Pet-friendly: Most rest areas have pet areas. Hotels in St. George accept pets.
• Hidden off-route: The ghost town of Calico near Barstow is a 20-min detour.

Fatigue management: The long straight sections near Baker can induce drowsiness. Stop every 2 hours. The stretch from Las Vegas to St. George has more curves to keep alert.

Leaving Claremont, the San Gabriel Mountains dominate the rearview. Soon, the landscape flattens into the Mojave Desert. Joshua trees appear near Kramer Junction.

Between Baker and Primm, the terrain is stark salt flats. The temperature often exceeds 100°F in summer. At the Nevada border, the stark desert gives way to the Virgin River Gorge in Arizona/Utah.

Near Orderville, red rock cliffs of the Grand Staircase-Escalante National Monument surround the town.

• Mojave National Preserve: Side trip to Kelso Dunes.
• Valley of Fire State Park: 1 hour detour from I-15 near Overton.
• Zion National Park: 30 miles from Orderville.

Local commerce: In Orderville, find handmade crafts at the Frontier Homestead. In Las Vegas, sample buffets. Between stops, small towns like Mesquite have outlet shopping.
