Spokane to Buffalo: Epic Road Trip Across the Inland Northwest

The journey from Spokane, WA to Buffalo, WY spans approximately 500 miles along I-90 east and US-87 north.

The drive takes about 8 hours without stops, but plan for a full day to explore.

The route offers diverse landscapes: arid sagebrush steppe, dense pine forests, and rolling grasslands. Key highways include I-90 from Spokane to Sheridan, WY, then US-87 north to Buffalo. Driving time is roughly 8.5 hours, but with stops it can extend to 12 hours. For tips on how to find the best stops and hidden gems between cities, check that guide.
