Pullman to Buffalo: Scenic Road Trip Guide

This route crosses the Rockies on Interstate 90, connecting the Palouse's rolling wheat fields to buffalo country. The drive spans roughly 850 miles, but the real distance is felt in the changing ecosystems—from arid steppe to alpine forests.

After crossing the Continental Divide, the landscape transforms into high desert. Buffalo sits at the foot of the Bighorn Mountains. Stop at Little Bighorn Battlefield, a National Monument, to learn about the 1876 battle.

In Cody, WY, the Buffalo Bill Center of the West offers five museums. Smaller towns like Ten Sleep feature local ranching culture.

Long stretches between towns make planning essential. Take breaks every 2 hours; designated rest areas are spaced 30-60 miles apart on I-90. For families, the Yellowstone Wildlife Sanctuary in Red Lodge, MT, is a quick detour.

• Pet-friendly motels are common in larger cities; call ahead.
• Carry water and snacks for remote sections.
• Watch for wildlife at dawn/dusk.

Drive from Pullman on WA-270 to US-195, then join I-90 east through Spokane, Coeur d'Alene, and Missoula. Continue via I-90 to Buffalo, WY. The interstate is well-maintained, with regular rest areas and 24/7 fuel stops at major towns.

• Fuel prices drop west of Billings, MT; fill up there.
• Mountain passes (Lookout Pass, Homestake Pass) may close in winter; check conditions.
• Speed limits: 70-80 mph on open road.
