Jackson WY to Bonners Ferry ID: Scenic Road Trip Guide

Spanning approximately 600 miles, the drive from Jackson, WY to Bonners Ferry, ID via US-26, US-20, I-15, and US-95 typically takes 10 to 12 hours of pure driving time—excluding stops. This corridor traverses the Snake River Plain, the Caribou-Targhee National Forest, and the Bitterroot Range, offering a transect of the northern Rocky Mountains. The highway crosses the Continental Divide at Teton Pass (8,431 ft) and again near Monida Pass (6,820 ft), a historical route used by the Oregon Trail. A peculiar local quirk: in Idaho, the speed limit on rural two-lane highways is 70 mph, but sections through Yellowstone National Park are limited to 45 mph due to wildlife crossings. The route's variable elevation and remote stretches demand careful planning.

Fuel stations are sparse between towns, especially after leaving Jackson. The longest gap is from Dubois, ID to Salmon, ID (about 80 miles with limited services). Carry a full tank and emergency supplies. Gas prices in Idaho are typically $0.10-$0.20 cheaper per gallon than in Wyoming.

• Vehicle: A high-clearance vehicle is recommended for side roads. Snow tires or chains are required in winter (Oct–April).
• Navigation: Cell service is intermittent, especially in the Centennial Mountains and the Salmon River Valley. Download offline maps.
• Accommodations: Hotels in Idaho Falls and Missoula are abundant; book ahead in summer. In smaller towns, motels and B&Bs suffice.

Road quality is generally good: I-15 is well-maintained concrete. US-20 and US-95 are asphalt with occasional frost heaves. Construction delays occur in summer—check Idaho 511. The route passes through several time zone changes: Jackson is Mountain Time; most of Idaho is Mountain, but Bonners Ferry is Pacific Time. Adjust your schedule accordingly.

As you head north on I-15, the landscape transitions to sagebrush steppe near Dubois, then to pine forests of the Caribou-Targhee. The Beaverhead Mountains are visible to the west. Near Dillon, MT, the Big Hole River is a blue-ribbon trout stream. The town of Wise River offers rustic lodging. Continuing through the Bitterroot Valley, the Sapphire and Bitterroot ranges frame the highway. The Lee Metcalf National Wildlife Refuge near Stevensville is a birding hotspot.

Note: The sale of alcohol is restricted in some counties on Sundays; buy your Idaho wine in Coeur d'Alene.

Wildlife collisions are a risk, especially at dawn and dusk. Elk, moose, and deer are common on US-20 near Henrys Lake and on US-95 near Sandpoint. Drive with high beams when safe, and watch for reflective eyes. In winter, black ice forms on shaded curves of Teton Pass. Carry a winter survival kit: blanket, shovel, sand, and extra food.

For off-leash areas, the Bundy Dog Park in Missoula is fully fenced. Avoid leaving pets in hot cars at scenic stops.

Hidden off-route spots: For a thermal soak, drive 10 miles north of Lava Hot Springs (exit 47 on I-15) to the Portneuf River. The natural hot pools are free and uncrowded.
