Thermopolis to Dubois: Wyoming's Wild Beauty

The drive from Thermopolis to Dubois covers 113 miles of US-20, climbing from the Bighorn Basin at an elevation of 4,620 feet to the Wind River Mountains at 6,977 feet. The route crosses the Wind River Canyon, a spectacular gorge carved by the Wind River through the Owl Creek Mountains. This canyon, with its towering limestone walls and abundant bighorn sheep, is geologically significant, featuring rock formations from the Precambrian era to the Paleozoic era.

The highway follows the history of the Oregon Trail, which passed through this region in the mid-19th century. Pioneers faced similar challenges of steep grades and extreme weather. Today, the route is fully paved and accessible year-round, though winter conditions can be harsh.

When planning your trip, consider the total driving time: approximately 2 hours without stops. However, with the many how to find the best stops and hidden gems between cities, you'll want to allocate a full day to explore.

Road safety is paramount. The winding canyon roads demand attention, especially for trailers and large RVs. The highway has no shoulders in many areas, so pullouts are provided at scenic points. In winter, black ice is a hazard, especially in shaded areas.

For families, the route is suitable for children, with several educational stops. Hot Springs State Park offers a boardwalk through the mineral terraces and a bathhouse. In Dubois, the Sheep Center is interactive and kid-friendly. The drive itself can be a highlight if you play a game of spotting bighorn sheep (you'll see them!)

Fatigue management is crucial; take breaks at the rest areas. There is a rest area at the south end of Wind River Canyon (mile 30) with picnic tables. Another at Boysen State Park (mile 5) has restrooms and a boat launch. Plan to stop every 45 minutes to avoid drowsiness.

Pet-friendly: Dogs are welcome at Hot Springs State Park (on a leash) and most roadside pullouts. Bring fresh water, as the summer sun can heat the car. In Dubois, the National Bighorn Sheep Interpretive Center allows service animals only, so plan accordingly.

Culinary options are limited; pack a lunch or picnic. There are no restaurants inside the canyon. In Thermopolis and Dubois, you'll find diners and cafes serving hearty Wyoming fare, but they may close early in the off-season.

Fuel availability is sparse; fill up in Thermopolis or Dubois, as the only station in between is at the small community of Hamilton (around mile 70). The route has no tolls, and road conditions are generally good, maintained year-round by the Wyoming Department of Transportation. In winter, chains may be required during snowstorms; check 511wyoming.com for updates.

The most famous attraction is Hot Springs State Park in Thermopolis, home to the world's largest mineral hot spring. Visitors can soak in the free state bathhouse. The park features a suspension bridge over the Bighorn River and terraced mineral formations.

As you drive, you'll pass through the Wind River Canyon, a designated National Scenic Byway. The canyon's cliffs reveal billion-year-old granite, and you might spot wildlife like bighorn sheep and golden eagles. At the north end, a scenic overlook offers a panoramic view of the canyon and the river below.

Beyond the canyon, the landscape opens into rolling sagebrush plains and volcanic hills. Near mile 85, you'll encounter the geological wonder of the Ramshorn, a looming peak that marks the beginning of the Wind River mountains.

In Dubois, local commerce is driven by tourism and ranching. The town hosts the National Bighorn Sheep Interpretive Center, where you can learn about the region's sheep population. Along the way, a handful of small ranches sell local produce and crafts; look for roadside stands near the town of Hamilton.

In terms of UNESCO World Heritage Sites, the region is not designated as such, but Yellowstone National Park, about 70 miles from Dubois, is a UNESCO site worth a detour if you have time.
