Jamestown to Buffalo Road Trip: Plains to Bighorns

The road from Jamestown, ND to Buffalo, WY spans approximately 370 miles along Interstate 94 and Interstate 90, with a driving time of about 5.5 hours without stops. This route traces the gradual transition from the flat glacial plains of the Red River Valley to the rolling prairies of Montana and the dramatic foothills of the Bighorn Mountains.

A little-known fact: the stretch of I-94 in western North Dakota follows the old Yankton Trail, a 19th-century stagecoach route linking the Missouri River to the Montana goldfields. Today, the highway passes within sight of the Killdeer Mountains, an ancient plateau that rises unexpectedly from the prairie—a geologically significant outlier of the Rocky Mountains.

This guide covers everything from fuel economics to hidden off-route spots, helping you find the best stops and hidden gems between cities.

Safety on this route is generally high, but the long, straight stretches of interstate can induce highway hypnosis—a dangerous lull in attention. Combat fatigue by planning a stop every two hours.

Notable pet-friendly stops include the Glendive KOA (mile 340) with a dog park and the Buffalo RV Park (mile 370) with fenced runs. Always carry water and waste bags, as the prairie summer heat can be intense.

Climatic conditions vary dramatically. Summer temperatures range from 70°F (21°C) to 100°F (38°C), with afternoon thunderstorms common. Winter brings snow, ice, and whiteout conditions; check ND Roads and MT 511 apps for closures.

Culinary infrastructure is dominated by classic American diners and fast food. Local specialties include knoephla soup (a creamy potato-dumpling soup) at the Kroll's Diner in Bismarck, and buffalo burgers at the Lonesome Dove Cafe in Buffalo. For a quicker bite, try the Runza chain (a yeast bun filled with beef, cabbage, and onions) with outlets in Bismarck and Dickinson.

The journey begins in the flat, fertile plains of the Red River Valley, where fields of wheat and soybeans stretch to the horizon. As you head west near Bismarck, the terrain subtly rises into the Coteau du Missouri, a glacial drift prairie dotted with pothole lakes and wetlands. By Dickinson, the landscape opens into the Little Missouri Badlands—eroded buttes and canyons that form the western edge of Teddy Roosevelt National Park.

This route uses I-94 west from Jamestown through Bismarck and Dickinson, then merges onto I-94 west at the Montana border, continuing to I-90 west near Billings, and finally US-87 south to Buffalo. The entire drive is on well-maintained interstate highways except for the final 50 miles on US-87, a two-lane highway through the Bighorn Mountains.

Key refueling points: Bismarck, ND (mile 160), Dickinson, ND (mile 260), Glendive, MT (mile 340), and Miles City, MT (mile 420). Plan to fill up when below half tank, especially between Dickinson and Glendive where stations are 60-80 miles apart.
