Bonners Ferry to Evanston Road Trip: Scenic 582-Mile Guide

This road trip begins in the northern Idaho panhandle at Bonners Ferry, historically a Kootenai tribe gathering place and an 1880s railroad town. The 582-mile route ends in Evanston, Wyoming, once a Union Pacific railroad division point and now a gateway to the Uinta Mountains. Most drivers take about 10 hours of pure driving time, but plan for 2–3 days to absorb the landscapes.

The journey crosses the Continental Divide twice, follows portions of the Lewis and Clark National Historic Trail, and passes through parts of the Greater Yellowstone Ecosystem. You'll experience a dramatic shift from moist cedar forests to high desert sagebrush.

The route primarily follows US-95 south to I-90 east, then I-15 south to US-30 east. Road conditions are generally good, but expect mountain passes like Lookout Pass and Monida Pass to be slick in winter. Cell service is sporadic in rural Montana and Wyoming; download offline maps.

• Major fuel stops: Coeur d'Alene (ID), Missoula (MT), Bozeman (MT), Idaho Falls (ID).
• Gas prices vary by ~$0.50 per gallon; fill up in larger towns for better rates.
• Rest areas are spaced about every 50–70 miles on interstates; some on US-95 are sparse.

No tolls are on this route. All interstates have 80 mph speed limits in Montana and Wyoming, but weather often forces slower speeds. For real-time traffic and road closures, call 511.

Natural highlights include the Selkirk and Bitterroot mountains, the sagebrush steppe of the Snake River Plain, and the volcanic formations near Idaho Falls. The route passes just south of Yellowstone National Park, though not directly through it. The UNESCO World Heritage Site of Yellowstone is a worthwhile detour, adding about 2 hours, but the main route itself offers no UNESCO sites.

Local commerce along the way reflects ranch culture and outdoor recreation. Farm stands appear seasonally in Montana, and small towns like Ashton, Idaho, are known for their potato farms. In Evanston, check out the historic downtown railroad depot. For off-route gems, consider a short drive to the lava flow fields at Craters of the Moon National Monument (about 20 miles off I-15 near Arco).

Winter driving requires chains in some passes; summer brings thunderstorm hail. Wildlife crossings are frequent (elk, mule deer) at dawn and dusk. Be extra cautious between Drummond and Garrison, Montana, where animals often cross.

Family-friendly stops include the Grizzly & Wolf Discovery Center in West Yellowstone, the Museum of the Rockies in Bozeman, and the Teton County Fair in Driggs (June to August). Many restaurants have high chairs and kids' menus at major towns.

For pets, most national forest trails allow dogs on leashes; many hotels are pet-friendly, but always confirm. Plan rest stops every 2 hours: good pullouts exist at scenic overlooks like the Clark Fork River viewpoint near Missoula.
