Wallace to Dickinson: Plains, Peaks, and Prairie

The drive from Wallace, Idaho to Dickinson, North Dakota begins in a town that once billed itself as the 'Silver Capital of the World'—a claim rooted in the 1880s mining rush that left over 100 miles of underground tunnels beneath the streets. As you head east on I-90, you'll leave the Bitterroot Mountains and cross the Continental Divide at Homestake Pass (elevation 6,329 feet), then descend into the high plains and eventually the Badlands of the Dakotas. This route spans roughly 1,030 miles and typically takes about 15 hours and 30 minutes of pure driving, not counting stops.

If you're wondering is it worth driving Wallace, ID to Dickinson, ND, the answer depends on your appetite for dramatic geological transitions—from steep, forested canyons to rolling wheat fields and moon-like badlands. The journey crosses two time zones (Mountain to Central), and you'll pass through parts of Montana's famous 'Big Sky' country, where the sky seems to take up half the world. Below is a quick reference for the itinerary.

Stick to I-90 east from Wallace through Montana, then take US-85 north at Belfield, ND to reach Dickinson. The interstate is well-maintained, with speed limits of 80 mph in Montana and 75 mph in North Dakota. For the question how long to drive Wallace, ID to Dickinson, ND, plan on 15.5 hours of driving, but budget at least two days to enjoy the sights. The route is entirely within the Mountain and Central time zones, so set your clock back one hour when crossing the Montana/North Dakota border near Wibaux.

Fuel costs vary, but as of 2025, expect to pay around $3.50 per gallon in Montana and $3.20 in North Dakota. Budget roughly $150–$200 for gas alone for an average SUV. There are ample fuel stops along I-90 every 30–50 miles, but once you leave the interstate for US-85, stations become sparse—fill up in Belfield before heading north. Roadside assistance is available through AAA, but cell coverage is spotty in rural stretches; consider downloading offline maps.

The route offers a stunning array of natural landscapes. Starting in Wallace, you're surrounded by the Coeur d'Alene National Forest, with pine-covered slopes and the scenic Nine Mile Creek canyon. As you head east, the mountains give way to the vast Montana prairie, where you'll see the massive Pompeys Pillar—a 150-foot sandstone butte bearing the signature of William Clark (of Lewis and Clark) from 1806, now a National Historic Landmark. Further east, in North Dakota, Theodore Roosevelt National Park (South Unit) features the badlands—eroded clay and sandstone formations in shades of tan, red, and gray, with free-roaming bison and wild horses.

For things to do between Wallace, ID and Dickinson, ND, consider a detour to the Little Bighorn Battlefield National Monument (30 miles south of I-90 near Crow Agency, MT), where you can walk the battlefield and learn about Custer's Last Stand. Another gem is the Moss Mansion in Billings, a 1903 red sandstone house listed on the National Register of Historic Places. In Dickinson, the Dickinson Museum Center offers a glimpse into the region's ranching and Native American history.

Local commerce along the way includes small-town cafes and farm stands. In Montana, you'll find huckleberry treats—try a huckleberry milkshake at a diner in Butte or Drummond. In North Dakota, look for chokecherry jam and local honey at roadside markets. For a break, visit the town of Medora, ND, just south of the park, which offers chuckwagon dinners and a nightly musical, 'Medora!'

The route is generally safe, but winter driving from November to March can bring snow and ice, especially over Homestake Pass and in North Dakota. Check forecasts and carry chains. The road quality is excellent, with wide shoulders and clear signage. For families, there are several engaging stops: Pompeys Pillar has a hands-on visitor center with a mosaic of Lewis and Clark artifacts. The Theodore Roosevelt National Park offers junior ranger programs for kids. Restrooms are available at gas stations and rest areas; the Montana rest areas often have interpretive panels about local history.

Fatigue management is crucial on this long drive. Use the 'Stop, Walk, Refresh' method: every two hours, stop at a rest area or small town, stretch, and grab a coffee. Notable safe rest stops include the Bozeman Rest Area (mile 313) with scenic views, and the Glendive Rest Area (east of Miles City) with clean facilities. For overnight stays, Billings offers a range of hotels from budget to luxury; consider the historic Northern Hotel downtown. If you're traveling with pets, most hotels along I-90 are pet-friendly, and there are plenty of grassy areas for breaks. National parks allow leashed pets on roads and in parking lots but not on trails.

Hidden off-route spots include the ghost town of Garnet, MT (southeast of Missoula) with preserved 1890s buildings, and the Makoshika State Park near Glendive, MT, featuring dinosaur fossils and scenic overlooks. For a quiet picnic, take the exit at Terry, MT, and stop at the Fallon Interpretive Park, which has a replica of a Mandan earth lodge.
