Butte to Watford City: Road Trip Through Montana & Dakota

The drive from Butte, Montana to Watford City, North Dakota covers 380 miles along I-94 and US-85, taking roughly 6.5 hours without stops. This stretch crosses the Continental Divide twice, passes through the historic mining town of Butte, and ends near the rugged badlands of the Little Missouri River. The route is a study in contrasts: from the copper-laced hills of Montana to the oil-boom towns of North Dakota.

One little-known fact: Butte’s Berkeley Pit, a mile-wide former open-pit copper mine, is now a toxic lake that actually kills migrating geese. It’s a sobering reminder of the region’s industrial past. As you drive east, you’ll see the landscape transform from conifer forests to rolling prairies, then to the lunar-like badlands of the Theodore Roosevelt National Park area. This guide covers everything from fuel economics to hidden off-route gems.

The drive begins in Butte, surrounded by the Highland Mountains, then climbs over the Continental Divide at Homestake Pass (elevation 6,329 ft). Shortly after, you drop into the Gallatin Valley and pass near Bozeman, gateway to Yellowstone. The landscape here is wide-open ranchland with the Bridger Mountains to the east.

• Big Timber: Home to natural hot springs and the Crazy Mountains

Near Billings, the land flattens into the high plains. But the real spectacle is the badlands of Theodore Roosevelt National Park, just south of Watford City. The park’s North Unit offers dramatic vistas, petrified forests, and bison herds. Entry fee is $30 per vehicle. For hidden off-route spots, consider the Painted Canyon Overlook on I-94 east of Belfield — a stunning roadside viewpoint.

Commerce shifts from Montana’s outdoor recreation economy to North Dakota’s oil industry. Watford City has boomed with hotels, fast food, and service stations. Local shops sell Western gear and Native American crafts. For a unique stop, visit the Makoshika State Park near Glendive, which features dinosaur fossils and a scenic drive.

Fuel stations are plentiful along I-94 but sparse on US-85 after Belfield. Plan to fill up in Butte, Bozeman, and Billings. Diesel is widely available. The best fuel prices are often at Costco in Billings or small-town stations like in Glendive. Expect to pay around $3.50 per gallon (2024 average).
