Thermopolis to Alpine: Wyoming's Scenic Drive

The drive from Thermopolis to Alpine, WY, spans over 200 miles of diverse Wyoming terrain, starting in the Bighorn Basin and climbing into the Rocky Mountains. You'll traverse the Wind River Canyon, a narrow gorge carved by the Wind River, where the rock layers reveal 3 billion years of geological history. This route is not just a commute; it's a journey through ancient landscapes and pioneer history.

US-20/26 are two-lane highways with 65 mph speed limits, but curves and wildlife crossings require caution. In winter, Togwotee Pass can be treacherous, so carry tire chains and emergency gear. The Wyoming Highway Patrol patrols regularly, but cell coverage is sparse in the canyon and mountain areas.

For families, the Wind River Canyon offers easy pull-offs for picnicking, but the most engaging stop is the Wyoming Dinosaur Center in Thermopolis, which features real fossils. Pet-friendly rest stops include the Dubois Park and the rest area at Moran Junction, both with shade and water. Plan to stop every two hours; Dubois and Moran Junction are ideal. Watch for fatigue on the long, straight stretches.

Hidden gems include the drive up the gravel road to Brooks Lake, 10 miles north of Dubois, offering serene views. Also, just south of Alpine, the Snake River Canyon is a scenic detour where you might spot osprey.

US-20 and US-26 form the backbone of this trip, merging near Dubois and later joining US-191. Fuel is available in Thermopolis, Dubois, and Alpine, with the longest stretch without services spanning about 70 miles between Dubois and Moran Junction. Expect to pay around $3.50 per gallon for regular gas, which is on par with national averages.

Bridge construction on US-26 east of Moran Junction sometimes causes delays of 15-30 minutes during summer. Chains may be required in winter on Togwotee Pass, which reaches 9,659 feet. There are no toll roads on this route, and all highways are well-marked.

The Wind River Canyon serves as a dramatic introduction to the trip, with its steep walls and the Wind River paralleling the road. Further north, the Absaroka Range looms to the west. At Dubois, the National Bighorn Sheep Center offers insights into the local herd. The route also skirts the southern edge of Yellowstone National Park, but the park’s main attractions are a detour.

Dubois and Bondurant are small ranching towns where local commerce includes rustic diners and outfitters. Dubois features the Cowboy Cafe, known for its hearty breakfasts, while Bondurant has a general store. The area is rich in Western heritage, with the Wind River Indian Reservation nearby, where visitors can learn about the Eastern Shoshone and Northern Arapaho tribes.
