Jackson to Salmon: Ultimate Road Trip Guide

One subtle but telling detail from this route: the Continental Divide crosses US Highway 26/287 near Togwotee Pass at 9,658 feet. As you drive from Jackson, WY to Salmon, ID, you'll cross the Divide twice – once on this pass and again on US-20 near Monida Pass. This geological spine divides watersheds, meaning your journey begins in the Snake River drainage and ends in the Salmon River basin.

The drive covers approximately 200 miles, taking around 4.5 hours without stops. However, the allure of the Teton and Beaverhead mountain ranges, plus the wildlife-rich corridors of the Greater Yellowstone Ecosystem, makes it far longer if you pause for experiences. The route weaves through Wyoming's national forests and Idaho's high desert, a dramatic transition in ecosystems.

Fuel and Route Economics

Gas stations are sparse, especially after Dubois (WY) until Lima (MT) – a 90-mile stretch. Fill up in Jackson or at the Sinclair station in Dubois. In Idaho, fuel is available in Leadore and Salmon, but no stations between Monida Pass and Leadore (60 miles).

• Jackson (WY): Multiple stations, premium gas available.
• Dubois (WY): Sinclair and a local station; last stop before the high passes.
• Lima (MT): After leaving Wyoming, this is the only option until Leadore.
• Leadore (ID): Small station; limited hours.
• Salmon (ID): Full-service town with several stations.

Climatic Conditions & Route Aesthetics

The route passes through three distinct climate zones: Jackson's intermountain valley (cool summers, snowy winters), the high alpine of Togwotee Pass (subalpine, short growing season), and the semiarid sagebrush steppe of eastern Idaho. Summer afternoon thunderstorms are common; winter travel is hazardous.

• June-September: Prime window. Daytime highs 70-80°F, nights 40-50°F.
• October-May: Snow possible, passes may close. Carry chains.
• Seasonal closures: Togwotee Pass (US-26/287) occasionally closes for avalanches. Check WYDOT.
