Las Vegas to Moab Road Trip Guide: Ultimate Desert Journey

Completed in 1910, the Arrowhead Trail was one of the first auto routes connecting Las Vegas and Moab, but today's I-15 and US-190 corridor offers a far smoother ride. The route spans 420 miles, crossing the Mojave Desert, the Virgin River Gorge, and the Colorado Plateau, with a dramatic elevation gain from 2,000 feet in Las Vegas to over 4,000 feet in Moab.

Drivers navigate through two states, passing near several national parks and monuments. The how to find the best stops and hidden gems between cities approach transforms this transit into a curated adventure.

From Las Vegas, take I-15 north for 120 miles to St. George, Utah. Continue on US-190 east through Hurricane, Virgin, and Mount Carmel Junction, then connect to US-89 and US-160 toward Moab. The final 30 miles follow US-191 into town.

• Fuel stations cluster around St. George (mile 120) and Green River (mile 340), with a 50-mile gap between Scenic (no gas) and Kane Springs (limited hours).
• Restrooms available at the Virgin River Gorge rest area (mile 100) and Valley of Fire State Park (mile 60).
• Electric charging stations exist in St. George and Moab; plan for Level 2 charging at hotels.

The road condition is generally excellent, with maintained asphalt throughout. Winter storms can close the Virgin River Gorge or cause ice on higher elevations. Always check weather alerts before departure.

I-15 has a 70 mph speed limit with frequent patrols. US-190 narrows to two lanes with 55 mph limits; passing opportunities are limited. Wildlife (mule deer, bighorn sheep) frequently cross near dusk. Keep emergency supplies: water, snacks, blankets.

• For families: stop at St. George's Children's Museum or the Dinosaur Discovery Site in Moab.
• Pet-friendly: many hotels in Moab accept pets, and the Moab Bark Park off US-191.
• Rest zones: the Virgin River Gorge rest area (mile 100) and the scenic overlook near Moab (mile 410) provide safe breaks.

Fatigue management requires a break every 2 hours. The small town of Hurricane offers a quirky diner (The Wagon Wheel) and a park. For longer rest, consider spending a night in St. George or Blanding. The drive's monotony is broken by dramatic landscape shifts: from stark desert to red rock canyons and pine forests near Grand Staircase-Escalante.

The route passes two UNESCO World Heritage Sites: Grand Canyon National Park (via South Rim detour, 80 miles off-route) and Mesa Verde National Park (50 miles east of Moab). While the direct drive doesn't include these, the landscapes rival their grandeur. Valley of Fire State Park offers petrified logs and red sandstone formations, while Snow Canyon State Park near St. George features lava tubes and volcanic craters.

• Valley of Fire: 40 miles northeast of Las Vegas, entry $10/vehicle.
• Snow Canyon: 10 miles northwest of St. George, hiking trails for all levels.
• Red Cliffs National Conservation Area: 15 miles northeast of St. George, home to the threatened Mojave desert tortoise.

Local commerce thrives on tourism and mining. St. George's historic downtown sells handcrafted turquoise jewelry, while Moab's Main Street overflows with outdoor gear shops and galleries. Hidden off-route spots include the ghost town of Sego (off UT-24) and the petroglyphs at Wolfe Ranch near Arches.
