Dickinson to Dillon: Road Trip Guide

The route from Dickinson, ND to Dillon, MT spans roughly 640 miles along I-94 and I-90, passing through the Missouri River Valley and the Rockies. This drive typically takes 9–10 hours without stops, but plan for at least 11 with breaks.

The most direct path follows I-94 west to Billings, then I-90 south to Dillon. Along the way, fuel prices and elevation changes affect your fuel economy; crossing the Continental Divide at Homestake Pass (elevation 6,329 feet) adds scenic but demanding terrain.

You'll cross the Missouri River near Glendive, MT, where the badlands offer stark, eroded rock formations. Further west, the Rocky Mountains appear near Bozeman, with the Tobacco Root Mountains visible as you approach Dillon.

Local commerce thrives in small towns like Miles City, known for its Western heritage and the Range Riders Museum. In Dillon, the historic Beaverhead County Courthouse anchors the downtown, with locally-owned shops along Montana Street.

• UNESCO Sites: none directly on route, but nearby (Yellowstone NP)
• Climate: arid, with hot summers (90°F) and cold winters (-10°F)
• Culinary: classic steakhouses and diners in every town
