The most efficient route follows US-20 east from Ketchum to I-15 near Idaho Falls, then north on I-15 to Dillon, Montana. From there, I-90 east to Billings, then I-94 northeast to Dickinson. Road conditions are generally excellent, with well-maintained interstates and state highways. However, remote stretches in Idaho and Montana have limited services.

• Fuel stops: Plan fuel stops every 150-200 miles; reliable stations exist in Arco, ID; Dillon, MT; Forsyth, MT; and Glendive, MT. Some stations in between may have limited hours.
• Rest areas: Scattered along interstates but sparse on US-20. Notable rest stops: Craters of the Moon Rest Area (ID), Interstate 15 Rest Area near Dell (MT), and I-94 Rest Area near Beach (ND).
• Accommodations: Midpoints include Idaho Falls (many hotels), Dillon (motels), Billings (full-service hotels), and Glendive (budget lodges).

Mobile coverage is spotty in rural areas, especially through the Idaho-Montana border. Download offline maps and carry a paper map. Winter travel requires snow tires and emergency kits, as mountain passes can be treacherous.

This journey showcases an array of natural wonders. From the jagged Sawtooth Range near Ketchum to the surreal lava flows of Craters of the Moon, the landscape shifts dramatically. The best stops Ketchum, ID to Dickinson, ND include the Craters of the Moon National Monument (Arco, ID), where you can hike through volcanic terrain.

Further east, the Montana plains offer expansive vistas and the Yellowstone River Valley. Near Billings, the Pictograph Cave State Park reveals ancient rock art. In North Dakota, the badlands near Theodore Roosevelt National Park (north of Dickinson) feature colorful sedimentary layers and abundant wildlife, including bison and prairie dogs.

Local commerce along the route includes small-town businesses: in Arco, the Pickle's Place serves hearty meals; in Dillon, the Patagonia store offers outdoor gear; and in Glendive, the Frontier Gateway Museum showcases local history. For authentic souvenirs, stop at roadside stands selling huckleberry products in Idaho and Native American crafts in Montana.

Safety along this route is generally high, but drivers should be wary of wildlife, especially deer and elk at dawn/dusk. Speed limits on interstates are 75-80 mph, but reduce in construction zones. The road quality is good, but sections of US-20 in Idaho can be narrow and winding.

For families, kid-friendly stops include the Idaho Falls Zoo at Tautphaus Park, the Museum of the Rockies in Bozeman (a short detour), and the Dickinson Museum Center with its dinosaur exhibits. The things to do between Ketchum, ID and Dickinson, ND for children are abundant.

Fatigue management is crucial given the long drives between cities. Plan to stop every 2 hours. Designated rest zones: the Craters of the Moon picnic area, the Clark Canyon Reservoir near Dillon, and the rest areas along I-94. Pets are welcome at most rest stops and outdoor attractions; keep them leashed. Many hotels in Idaho Falls and Billings are pet-friendly.

Hidden off-route gems include the ghost town of Bannack, Montana (detour south of Dillon), and the Makoshika State Park near Glendive, ND, with stunning badlands and fossil sites. These require a few extra hours but reward with solitude and beauty.
