Salmon to Bonners Ferry: Idaho's Scenic Drive Guide

Leaving Salmon at milepost 0 on US-93, the road shadows the Salmon River, which carves the second-deepest gorge in North America before turning north. The drive to Bonners Ferry stretches 263 miles, a route that climbs three mountain passes and crosses the Continental Divide at Lost Trail Pass (elevation 7,014 ft).

This is a journey through the heart of Idaho's wild country, where the pavement is a thin ribbon through vast forests and ranchlands. The question is not whether to drive it—the landscapes are compelling—but how to make the most of the 4.5 to 5.5 hours of driving, depending on stops and conditions.

For the most direct route, stick with US-93 north from Salmon, which passes through Lost Trail Pass Montana, then connects to I-90 east to Missoula, and finally US-95 north to Bonners Ferry. This is the route the 263-mile figure is based on, a scenic blend of river canyons, mountain passes, and broad valleys. For those who prefer a more direct path, consider the US-93 to US-12/US-95 route via Lolo Pass, which trims about 30 miles but adds an hour in mountain driving.

The landscape evolves dramatically: from the arid sagebrush of Salmon Valley to dense pine forests and alpine meadows, then to the glacial lakes and cedar groves of the Selkirk Mountains. This is a drive that rewards careful planning, not just for the destination but for the journey itself.

Fuel and Economics

Fuel prices are generally higher in smaller towns like Salmon (about $0.20-0.30 more per gallon than in Missoula or Coeur d'Alene). Plan to fill up in Hamilton (MT) or Missoula for the best rates. As of 2024, expect to pay around $3.50–$4.00 per gallon in Idaho, with variations by region.

• Gas stations are scarce between Salmon and Lost Trail Pass—last chance in North Fork (37 miles north of Salmon).
• After the pass, stations appear in Sula and Hamilton, MT.
• On the final leg from Missoula to Bonners Ferry, stations are frequent in larger towns like Thompson Falls and Sandpoint.

Road Quality and Safety

US-93 is a two-lane highway with sections of passing lanes, especially on grades. Portions of the route, particularly from Salmon to Lost Trail Pass, are winding and steep, with guardrails and occasional rockfall signs. Winter travel demands snow tires or chains; the pass closes rarely but conditions can be hazardous.

Road construction is common in summer; check Idaho 511 for updates. The speed limit is 55-65 mph, lower on curves. Cell service is intermittent between Salmon and Missoula, and between Sandpoint and Bonners Ferry; download maps before departure.

Family and Pet-Friendly Considerations

This route is family-friendly with rest areas at Lost Trail Pass and near Thompson Falls, which include picnic tables and restrooms. Many roadside stops are pet-friendly, but keep dogs leashed due to wildlife like elk and bears.

For children, the Bitterroot Valley offers the Missoula Carousel for Kids (in Missoula) and the Historical Museum at Fort Missoula, both educational. In Sandpoint, the Pend Oreille Bay Trail is a flat, stroller-friendly walk.

Fatigue Management and Rest Zones

Driving for over five hours requires breaks. The route has several designated rest areas: at Lost Trail Pass (mile 0), near Sula (mile 30), and at the Idaho-Montana border. Rest facilities are available at the Travel Information Center in Missoula (open 24/7).

Coffee stops for rejuvenation include the Roost Coffee House in Hamilton and the Monarch Coffee in Sandpoint. For a safe place to nap, rest areas are adequate; motels in Hamilton, Missoula, and Sandpoint offer day rates if needed.

Hidden Off-Route Spots

Just east of US-93 in Montana, the Blodgett Canyon trailhead (22 miles south of Hamilton) offers stunning granite cliffs and a 4-mile hike. North of Thompson Falls, the Thompson Falls State Park is a short detour for views of the falls.

Another gem is the Kootenai National Forest, which can be accessed from the route; the Yaak River Valley, though a longer detour, rewards with pristine wilderness. For a historical touch, the Mission Mountains appear near St. Ignatius, site of a historic mission founded in 1854.

Natural Attractions

The route offers access to several natural wonders. Lost Trail Pass is a historic route used by Lewis and Clark; a small interpretive sign marks the site. In Montana, the Bitterroot Valley is a birdwatcher's paradise, with the Lee Metcalf National Wildlife Refuge near Stevensville.

North of Missoula, the National Bison Range (now the bison range) east of the route near Moiese is a must-see for wildlife. Further north, Cabinet Gorge and Lake Pend Oreille are notable for their scenic beauty, with Cabinet Gorge offering a dam and viewpoints.

Cultural and Commercial Stops

Small towns pepper the route: Hamilton, MT (pop. 4,400) is known for its historic downtown and Daly Mansion. Thompson Falls, ID, offers a brief riverside break. Sandpoint is the largest town near the end, with a vibrant arts scene and local breweries.

Local commerce leans on ranching and logging; you'll see roadside stands selling huckleberries in season (July-August) and cherry orchards south of Bonners Ferry. In Bonners Ferry, the Kootenai County Farmers Market operates on Saturdays.
