Green River to Choteau: Epic Wyoming-Montana Drive

At Green River, Wyoming, the Continental Divide flirts with the highway, and the Green River itself, a Colorado River tributary, cuts through the sagebrush. This drive to Choteau, Montana, skirts the Wind River Range and the Absaroka-Beartooth Wilderness, climbing to elevations over 8,000 feet near Togwotee Pass

Fuel and Route Economics

Fuel prices vary, with Wyoming typically cheaper than Montana. Gas stations are sparse on stretches like US-191 between Rock Springs and Pinedale; fill up at Green River (several options) and plan to stop in Pinedale (about 80 miles) and Dubois (about 70 miles later).

• Gas prices: ~$3.50/gal (WY) vs ~$3.80/gal (MT) as of 2024.
• No tolls on this route.
• Cell service is patchy, especially in national forests; download offline maps.

Weather and Climate

Mountain passes can see snow even in June, and afternoon thunderstorms are common in summer. Average July high: 80°F in Green River, 75°F in Choteau; winter temps can drop below -20°F.

Infrastructure Safety & Road Quality

US-191 is two-lane and twisty, with wildlife (elk, moose) grazing near the road at dawn/dusk. US-89 to Choteau is in good condition, but gravel roads turn slick. Be prepared for delays due to road work in summer.

Family and Pet-Friendly Framework

Kids will love the National Museum of Wildlife Art (Jackson, detour) and the Green River Rendezvous (July). Pets are welcome at most roadside rest areas but not inside visitor centers. Pick up dog-friendly trails at Flaming Gorge (near Green River) or Pine Creek near Choteau.

Fatigue Management & Rest Zones

Drive 2-3 hours max between breaks. Designated rest areas: Pinedale, Dubois, and after Thermopolis. Plan for a 10-minute nap if drowsy. Consider overnighting in Dubois or Buffalo, WY.

Hidden Off-Route Spots

Just off US-191, the Petroglyph Canyon (Legend Rock) near Thermopolis has ancient carvings. In Montana, the Pine Butte Preserve offers undisturbed prairie.

Natural Landscapes and Attractions

The route rivals Yellowstone for scenery without the crowds. Highlights include the Wind River Canyon (Turner's Corners to Thermopolis), the Buffalo Bill Center of the West in Cody (off-route detour), and the Shoshone National Forest's East Entrance. In Montana, the Beartooth Highway (closed in winter) is a side trip to Red Lodge.

UNESCO World Heritage Sites and Culture

Within a short detour, you can visit the breathtaking Tetons (Yellowstone is a UNESCO World Heritage Site). Local commerce in small towns like Dubois (Wind River Wild Horse Sanctuary) and Choteau (Old Trail Museum) reflects frontier history. Rodeos in summer at Dubois and Choteau offer authentic local color.

Culinary Infrastructure

Dining is limited but solid: try the Sinks Canyon Cafe in Lander, the Wrangler Cafe in Dubois, and the Big Sky Bakery in Choteau. For a picnic, stock up at groceries in Pinedale (Wind River Trading Company) or Choteau.
