Stanley to Dickinson: Idaho to North Dakota Road Trip

Driving from Stanley, Idaho (elevation 6,260 ft) to Dickinson, North Dakota (elevation 2,450 ft) is a 900-mile journey through the heart of the American West. The route includes Idaho's rugged Sawtooth Range, Montana's rolling plains, and the badlands of North Dakota.

You'll traverse three states, cross the Continental Divide at 7,037 feet, and pass through tiny towns that seem frozen in time. This is not a quick hop; plan for at least 15 hours of pure driving time.

Starting from Stanley, the Sawtooth National Recreation Area offers towering granite peaks (10,000+ ft), alpine lakes, and abundant wildlife. Nearby is Craters of the Moon National Monument, a vast lava field with 25 volcanic cones, designated a UNESCO World Heritage site in 2024.

As you cross into Montana, the landscape softens into ranchland. In Livingston, visit the historical railroad depot (built in 1902) and grab a bison burger at a local diner. Further east, Little Bighorn Battlefield National Monument marks the 1876 battle; the visitor center has exhibits on the Lakota and Cheyenne perspective.

In Dickinson, the Dakota Dinosaur Museum houses a Triceratops skull discovered locally. The nearby Badlands offer unique geological formations (layered clay and sandstone). Local commerce thrives on oil, agriculture, and tourism; you'll see ranches selling beef jerky and handmade quilts along the highways.

For gourmet stops, seek out huckleberry treats in Idaho, and bison steaks in Montana. How to find the best stops and hidden gems between cities helps you locate farm stands and local museums.

Road quality is generally good: I-90 is well-maintained with 8-inch concrete in Montana. Winter driving is hazardous from October to April; carry tire chains and emergency supplies. Summer thunderstorms can produce hail, but the rest is clear.

For families, Yellowstone National Park is a 3-hour detour from Billings, offering geysers and wildlife. Animal warnings are frequent: watch for deer and elk at dawn/dusk, especially near rivers.

To combat fatigue, take breaks every 2 hours at rest areas like the one at mile 465 (west of Billings). For pets, most motels along I-90 accept dogs; there are designated pet areas at rest stops.

Hidden gems: stop at the tiny town of Roundup, MT (pop. 1,700) for its annual Bucking Horse Sale (June), or at Theodore Roosevelt National Park's south unit (35 miles from Dickinson) for scenic drives without crowds.

Most of the route follows Interstate 90 and US-12, with a scenic stretch on ID-75 through the Sawtooth Valley. Fuel costs average $4.20 per gallon; budget approximately $90 for a mid-size sedan based on 25 MPG. The most isolated stretch is between Butte, MT and Billings, MT where services are sparse for 120 miles.

• Remote stretches: plan fuel stops in Arco, ID (260 miles from Stanley) and Hardin, MT (90 miles from Billings).
• Diesel availability is good at interstate exits, but in rural sections, stations may close early.
• Cell coverage drops on US-12 between Lolo, MT and Missoula; download offline maps.
• The speed limit is 80 mph on I-90 in Montana, 70 mph in Idaho and North Dakota.
