Richfield to Pinedale: Epic Road Trip Guide

The route from Richfield, UT to Pinedale, WY spans 340 miles through the high desert and Rocky Mountains, a journey that climbs from 5,300 feet to over 7,000 feet. It traverses the historic Pony Express trail, following US-89 and US-189, passing the Sevier River and the Wasatch Range.

This drive offers a mix of national forests, fossil beds, and alpine lakes, with a population density thinning to fewer than 1 person per square mile in parts of Wyoming. The entire trip takes about 5.5 hours of pure driving, but plan for 7-8 hours to savor the sights.

Roads are well-maintained but winding in mountain sections; watch for deer and elk, especially at dusk. The average annual traffic fatality rate is 1.5 per 100 million vehicle miles, lower than the national average.

For families, the Wyoming Dinosaur Center in Thermopolis (990.7 miles off route) is a detour, but closer, the Bear River State Park near Evanston has a wildlife viewing area.

Pets are welcome at most outdoor stops; keep them leashed in national forests. The Muddy Creek trailhead offers a pet-friendly path.

• Rest zones every 30 miles on I-80, but none on US-189.
• Plan a break every 2 hours; the Sevier River Rest Area is a scenic spot.

Fatigue management is crucial: the monotonous interstate can lull you, so pull into the Evanston Coal Mine Viewpoint for a novelty break. Locals recommend the 7+2 rule: drive 7 hours, sleep 2, rather than pushing through.

Major highways are US-89 north to I-80 east, then US-189 north into Wyoming. Fuel stops are sparse beyond Evanston, so fill up when you can. Gas prices in Utah average $3.50/gallon, while Wyoming often runs $0.20 cheaper, making it economical to top off in Evanston.

• Restrooms available at most exits, but limited between exits 24-61 on I-80.
• Cell service is unreliable in mountain passes; download offline maps.
• No tolls on this route, unlike parts of I-80.

Bridger-Teton National Forest, a UNESCO Biosphere Reserve, covers much of the northern leg, offering free dispersed camping. For a plush stop, the Pinedale KOA (307-367-2222) provides full hookups.

Weather can turn quickly: expect snow as late as June at high elevations, and dry, dusty conditions in summer. Always carry chains.

The scenery transitions from red rock canyons to pine forests. In Wyoming, the Green River Valley opens into the Wind River Range, a dramatic contrast to the desert. Fossil Butte National Monument preserves 50-million-year-old fish fossils, a must-see for geology buffs.

Local commerce thrives on ranching: look for roadside stands selling sage honey and wool products. In Pinedale, the Museum of the Mountain Man recounts fur trade history, and the Wind River Brewing Company offers a local tasting room.

Hidden off-route gems include the Grizzly Peak overlook and the town of Kemmerer, home to the JCPenney Mother Store. These spots are accessible via county roads but require a high-clearance vehicle.
