Jackson to Hanksville: Utah's Ultimate Road Trip Guide

This 360-mile journey begins at 6,237 feet in Jackson Hole, Wyoming, and ends at 4,300 feet in Hanksville, Utah, crossing three mountain passes and the Continental Divide twice. Interstate 80 and US-191 form the main spine, but the true character lies in the backways.

The route traverses the Bridger-Teton National Forest, then drops onto the high desert of the Green River Basin before climbing again into the Uinta Mountains. It's a drive that shifts from alpine meadows to red rock canyons in just six hours.

You'll pass through towns like Pinedale, Rock Springs, and Vernal, each offering a distinct slice of Western life. The final stretch into Hanksville skirts the edge of the San Rafael Swell, a vast geological uplift.

Fuel is available in all major towns along the route, but the longest stretch without services is between Vernal and Hanksville (82 miles). Plan accordingly, especially in extreme heat or cold. Gas stations in small towns like Duchesne or Myton may close early.

Road quality is generally excellent: US-191 and US-40 are well-maintained, paved highways. However, between Vernal and Hanksville, the road narrows and winds through canyons. Watch for loose gravel on shoulders and occasional cattle crossings.

• Cell service is spotty after leaving Rock Springs and again east of Vernal. Download offline maps.
• The route uses two highways: US-191 from Jackson to Rock Springs, then US-40 from Rock Springs to Vernal, and finally UT-24 to Hanksville.
• Estimated driving time without stops is about 6 hours, but plan for 8-10 with sightseeing.
• Is it worth driving Jackson, WY to Hanksville, UT? Absolutely, for the stark contrast in landscapes and access to national parks.

Winter conditions can be severe from November through April. Carrying chains is recommended between Jackson and Pinedale. Summer thunderstorms bring sudden downpours and flash floods in washes, especially after passing Vernal. Always check weather forecasts.

For families, the best stops include the Wyoming State Museum in Rock Springs (free, interactive exhibits) and Dinosaur National Monument (quarry wall with fossils). The stretch from Vernal to Hanksville has few services, so pack snacks and water.

Fatigue management: Plan to stop every two hours. Rest areas are available at the Green River rest stop (mile 140) and near Duchesne (mile 220). Consider an overnight in Vernal to break the drive. The Lazy Dog Campground is pet-friendly.

• Pet-Friendly: Most national forest lands allow dogs on leash. Dinosaur National Monument permits pets in developed areas only.
• Culinary: In Pinedale, the Wind River Brewing Company serves excellent burgers. Rock Springs has authentic Basque cuisine at the Silver Sage.
• Infrastructure: Roads are in good condition but narrow in canyons. Wildlife (deer, pronghorn) crossing zones are common; drive at dawn/dusk with caution.
• Best stops Jackson, WY to Hanksville, UT: Pinedale's Museum of the Mountain Men, Fossil Butte National Monument (just west of Kemmerer), and the petrified wood displays in Jensen.

The first quarter of the drive takes you through the Bridger-Teton National Forest, with views of the Wind River Range. As you descend into Pinedale, the mountains give way to rolling sagebrush plains. The Green River appears near Rock Springs, a ribbon of green in the desert.

Rock Springs is a coal-mining town with a historic downtown. Stop at the Bunning Park for a quick stretch. The route then climbs into the Uinta Mountains, crossing the Continental Divide at 7,870 feet. This area is dotted with alpine lakes and aspen groves.

Beyond Vernal, the topography shifts dramatically. You enter the Uinta Basin, an arid region of badlands and buttes. The final leg on UT-24 passes the northern edge of the San Rafael Swell, a 30-mile-wide dome of sedimentary rock. This is a prime area for fossil hunting and photography.

• Natural Landscapes: Wind River Range, Uinta Mountains, San Rafael Swell
• UNESCO Sites: None directly on route, but Dinosaur National Monument (near Vernal) is part of the World Heritage listing for its fossil quarries.
• Local Commerce: Pinedale offers fly-fishing gear and cowboy gear. Duchesne sells local honey and craft jerky.
• Hidden Gems: The town of Myton has a vintage gas station serving excellent milkshakes. Look for the turnoff to Fantasy Canyon, a small area of eroded hoodoos.
