Buffalo WY to Kellogg ID Road Trip Guide | Wayro

The route from Buffalo, Wyoming to Kellogg, Idaho spans roughly 700 miles along I-90 and I-94, crossing the Powder River Basin, the Bighorn Mountains, and the Rocky Mountain front. The drive typically takes 11–12 hours without stops, but the landscape shifts dramatically from high plains to alpine forests.

At the Wyoming-Montana border, you'll pass through the site of the Battle of the Little Bighorn (Custer's Last Stand), a pivotal moment in U.S. history. This route follows part of the old Bozeman Trail, a key supply route for miners during the Montana gold rush.

Fuel stations are plentiful along I-90, but become sparse in stretches like between Sheridan, WY and Billings, MT. Gas prices are generally lower in Wyoming than in Idaho, so it's economical to fill up before crossing into Montana. Bring water and snacks, as services can be limited in remote areas.

• Major towns on route: Sheridan, WY; Billings, MT; Bozeman, MT; Butte, MT; Missoula, MT.
• Scenic alternative: US-12 over Lolo Pass, which offers breathtaking views but fewer services.
• Road quality is good, but watch for wildlife, especially deer and elk at dawn and dusk.

The drive takes you past the Bighorn Mountains, the Absaroka Range, and the Bitterroot Valley. In Montana, you'll cross the Continental Divide at Homestake Pass. Hidden gems like the Pictograph Caves State Park near Billings offer ancient rock art.

Most of the route crosses lands of the Crow and Northern Cheyenne tribes. For a deep historical insight, visit the Little Bighorn Battlefield National Monument. Local commerce emphasizes cowboy culture and mining heritage. In Buffalo, WY, the Occidental Hotel is a living museum of Western history.

Highway patrols are common on I-90, but speed limits vary from 70-80 mph. In winter, roads can be icy, so check conditions and carry chains if you're traveling off-season. Rest areas are spaced roughly 50 miles apart; use them to combat monotony.

For families, the Museum of the Rockies in Bozeman features dinosaur exhibits that fascinate kids. Many hotels in the region are pet-friendly, but confirm beforehand. Plan to stop every two hours to stretch and rotate drivers if possible. For an in-depth approach to planning your stops, check this guide on finding hidden gems.
