Moab to Buffalo Road Trip: Ultimate Guide

The drive from Moab, UT to Buffalo, WY covers approximately 650 miles of dramatic transitions from red rock canyons to high plains. A little-known fact: this route roughly follows the Old Spanish Trail, a historic trade route connecting Santa Fe to Los Angeles, with segments overlapping modern US-191 and I-80. The journey takes about 10–11 hours of pure driving time, but expect at least two full days to savor the landscapes.

From Moab's red rock arches east to the high deserts of Wyoming, the scenery shifts dramatically. Within an hour north of Moab, you'll encounter the Book Cliffs, a 1,000-foot escarpment stretching for hundreds of miles. Near Vernal, Dinosaur National Monument offers both fossil quarries and stunning canyon views. As you cross into Wyoming, the landscape flattens into the Great Divide Basin where you can stand on the Continental Divide multiple times along I-80.

Local commerce along the route reflects the region's ranching and mining heritage. In Rock Springs, the annual International Mother's Day Festival celebrates the town's diverse immigrant history. Rawlins boasts the Wyoming Frontier Prison Museum. Buffalo's Main Street is lined with historic saloons and the Occidental Hotel, where Butch Cassidy once stayed. For souvenirs, look for local turquoise jewelry and bison jerky. The phrase how to find the best stops and hidden gems between cities applies perfectly here—detours like the Flaming Gorge National Recreation Area (just 15 miles north of Vernal) are worth the extra time.

UNESCO World Heritage Sites: Dinosaur National Monument is not UNESCO but is a National Monument; however, nearby Mesa Verde (2 hours south of Moab) is UNESCO. The route itself does not pass through any UNESCO sites directly, but the area is rich in cultural history.

The primary highways are US-191 north from Moab to I-80 near Rock Springs, then I-80 east to Rawlins, and US-287 north to Buffalo. Fuel stations are sparse between Moab and Vernal (about 100 miles without services) and again between Rawlins and Buffalo. Plan to fill up in Moab, Vernal, Rock Springs, Rawlins, and before heading north from Rawlins.

• Moab to Vernal: 145 miles, no major towns. Fill up in Moab.
• Vernal to Rock Springs: 190 miles, services in Green River (exit 89).
• Rock Springs to Rawlins: 120 miles, stations at Wamsutter (exit 174) and Creston (exit 178).
• Rawlins to Buffalo: 195 miles, gas available at Muddy Gap (junction 287) and in Kaycee (last stop before Buffalo).

Average fuel economy matters: a 20-mpg vehicle uses about 33 gallons for the trip. Current prices vary from $3.50 in Utah to $3.80 in Wyoming. Budget about $115–$125 for fuel.

Road quality is generally good on US-191 and I-80, but watch for livestock on open-range sections, especially after Rawlins on US-287. Winter driving can be treacherous with snow and ice; summer brings high winds and occasional dust storms. The speed limit is 70–80 mph on interstates, 65 on two-lane highways. Always carry an emergency kit with water, blankets, and a flashlight.

Family-friendly stops: The Field House of Natural History in Vernal (dinosaur fossils), the Flaming Gorge Dam Visitor Center, and the Wyoming Dinosaur Center in Thermopolis (a detour but very kid-friendly). For pet breaks, rest areas along I-80 have designated pet areas. The best rest stops for dogs include the Little America rest area (mile 123) and the Rawlins rest area (mile 215). Always keep pets leashed and clean up after them.

Fatigue management: Plan for breaks every 2 hours or 100 miles. Notable rest zones: Green River Rest Area (mile 89 eastbound) has picnic tables and shade; Wamsutter Rest Area (mile 174) is basic but clean. For a proper stretch, get off at exit 168 (Creston) where there's a diner and gas station. Using this guide will help you find additional unwinding spots.

Hidden off-route spots: The White Mountain Petroglyphs near Rock Springs (take I-80 exit 104) offer ancient rock art with a short hike. The Killpecker Sand Dunes east of Rock Springs are the largest active dune system in North America—accessible via dirt roads. Near Buffalo, the Tie Hack Reservoir trail provides a peaceful walk through pine forests.
