Butte to Riverton Road Trip Guide: Scenic Drive Through Wyoming & Montana

The 400-mile drive from Butte, Montana to Riverton, Wyoming follows a corridor rich in mining lore, dinosaur fossils, and sweeping high desert landscapes. Notably, the road crosses the Continental Divide twice—once at Pipestone Pass (elevation 6,368 feet) and again near South Pass City, Wyoming. This route is not an interstate but a mix of US highways (I-90, US-287, US-26, and US-20) that offers a slower, more intimate encounter with the American West.

Driving time is roughly 6.5 hours without stops, but the real value lies in taking a full day or two to explore. The question how to find the best stops and hidden gems between cities is answered here by venturing off the main drag into state parks, historic towns, and fossil sites.

This guide provides detailed information on the best stops Butte, MT to Riverton, WY, helping you decide how long to drive Butte, MT to Riverton, WY based on your interests and whether is it worth driving Butte, MT to Riverton, WY for the scenery and attractions. We’ll cover road conditions, dining, and kid-friendly activities to ensure a memorable journey.

UNESCO World Heritage Sites

While no UNESCO sites lie directly on this route, you can detour to Yellowstone National Park (a World Heritage Site) via US-287 and US-20 through West Yellowstone. Alternatively, visit the Franklin D. Roosevelt Lake area in Idaho, but that’s far off route.

Hidden Off-Route Spots

• Red Rock Lakes National Wildlife Refuge: About 20 miles west of Lima, MT, this remote refuge is home to trumpeter swans and offers serene hiking.
• South Pass City State Historic Site: A well-preserved ghost town from the gold rush era, just 30 miles south of Lander on WY-28. Gold was discovered here in 1867.
• Wind River Canyon: The spectacular gorge between Shoshoni and Thermopolis features towering cliffs and a Native American fish weir. Pull over at the scenic overlooks.

Local Commerce & Culture

Dillon, Montana is a ranching and agriculture hub. Visit the Beaverhead County Museum. Dubois, Wyoming is a gateway to the Wind River Range and home to the National Bighorn Sheep Interpretive Center. Lander, Wyoming is a rock climbing mecca with a vibrant downtown. The Wind River Indian Reservation (Eastern Shoshone and Northern Arapaho) offers cultural sites like the Sacajawea Cemetery and the Fort Washakie Museum. Note that some areas may require permits for photography.

Road Surface and Conditions

The route from Butte to Riverton is primarily paved and well-maintained. However, sections of US-287 and US-26 in Wyoming can be narrow and winding, especially through the Wind River Canyon. Snow and ice are possible from October through April, and fog can reduce visibility in river valleys.

• I-90 from Butte to Whitehall is a divided highway.
• US-287 south of I-90 becomes a two-lane road with frequent passing lanes.
• Wind River Canyon (between Shoshoni and Thermopolis) has sharp curves and a 55 mph speed limit; watch for wildlife.

Fuel and Route Economics

Gas stations are sparse on long stretches; the distance between Dillon and Dubois is about 130 miles with limited services. Plan your fuel stops accordingly. As of early 2025, gas prices are similar between Montana and Wyoming (around $3.50/gallon).

• Last reliable gas before Dubois is in Lander or on US-26 at Fort Washakie.
• In Montana, fill up in Butte or Dillon; in Wyoming, fill up before crossing the Wind River Reservation.

Climatic Conditions & Route Aesthetics

Summer (June-August) is peak season with daytime temperatures 70-85°F and frequent afternoon thunderstorms. Spring and fall are cooler (40-65°F) with vibrant wildflowers or golden aspens. Winter brings snow and biting cold (10-30°F), but blue skies accentuate snow-capped peaks. The best months for clear photography are September and October.

Infrastructure Safety & Road Quality

The roads are generally safe, but rural sections lack shoulders and lighting. In winter, check road conditions on MDT and WYDOT sites. Carry snow chains. Cell service is spotty, especially in the mountains and on the reservation. Download offline maps.

• Emergency services: Rapid response in towns (Butte, Dillon, Lander, Riverton) but response times in remote areas can exceed 30 minutes.
• Wildlife crossings: Deer, elk, and bighorn sheep at dawn/dusk; reduce speed near water sources.

Family and Child Suitability

This route is highly suitable for families. Kids will love the Wyoming Dinosaur Center in Thermopolis (100+ miles east of Riverton, but worth a detour). The center has real dig sites and over 30 mounted skeletons. Also, the Hot Springs State Park in Thermopolis offers free public baths. In Dubois, the Tie Hack Historical Park features a reconstructed lumber camp. For animal lovers, the National Bighorn Sheep Center in Dubois has live exhibits.

Pet-Friendly Framework

Most National Forests and Bureau of Land Management areas allow dogs on leashes. The Wind River Indian Reservation requires pets to be leashed and cleaned up after. Many motels in Butte, Lander, and Riverton are pet-friendly (e.g., La Quinta, Super 8). Carry water for your pet, as opportunities to refill are limited between towns.

Fatigue Management & Rest Zones

Long stretches of two-lane highway can be monotonous. Plan stops every 2 hours or 100 miles.

• Rest areas: There is a rest area near Twin Bridges on I-90, and another near the Wyoming border on US-287. In Wyoming, rest stops are located at Jeffery City (WY-220) and near Shoshoni.
• Alternative breaks: Stretch your legs at the Beaverhead Rock State Park viewpoint (MT) or the Wind River Canyon scenic pullouts.

Culinary Infrastructure

For a small-town dining experience, stop in Dillon at The Beanery Coffee House & Café for excellent sandwiches and baked goods. Dubois offers The Cowboy Café for hearty breakfasts. In Lander, Gannett Grill serves local beef burgers and microbrews. For a taste of Wyoming’s famous beef, Meadowlark Restaurant in Riverton is a local favorite. Avoid chain fast food; seek out family-run diners for the best value.
