Buffalo to La Grande: Route Guide with Hidden Gems

Heading west from Buffalo, Wyoming (elev. 4,640 ft), you'll cross the Bighorn Mountains via U.S. Route 16, pass through the high desert of the Powder River Basin, then climb into the Black Hills of Wyoming before descending into the Grande Ronde Valley in Oregon. This 370-mile drive typically takes 6-7 hours without stops, but the journey's rewards are many—from the geologic spectacle of Devils Tower to the lush vistas of the Wallowa Mountains. Whether you ask 'how long to drive Buffalo, WY to La Grande, OR' or 'is it worth driving Buffalo, WY to La Grande, OR,' the answer lies in the diverse landscapes and small-town charm that make the American West so memorable.

Fuel economy varies with elevation changes: expect to spend roughly $45–$65 on gas for a typical sedan, but costs can be higher in small towns like Buffalo or Baker City, so fill up at larger hubs like Gillette or Bozeman (though Bozeman is off-route). On a budget? Combine fuel stops with meals to save time. Use an app like GasBuddy to find the cheapest prices along I-25 and I-90.

• Best stops Buffalo, WY to La Grande, OR: Devils Tower National Monument, Little Bighorn Battlefield, Craters of the Moon, and the Oregon Trail Interpretive Center.
• Interstate exits are well-marked; most rest areas have picnic tables and clean restrooms.
• The route is entirely paved and suitable for any vehicle, including RVs.
• Towing? Be cautious on US-16 over Powder River Pass (9,666 ft) – steep grades.

From Wyoming's shortgrass prairies to Oregon's alpine meadows, you'll traverse four distinct ecoregions. The centerpiece is Devils Tower—the first U.S. National Monument (est. 1906)—a 1,267-ft igneous intrusion that rises abruptly from the plains, sacred to over 20 Native American tribes. Further west, the Bighorn Mountains offer rugged granite peaks and alpine lakes, while the Black Hills of South Dakota (a short detour north) are forested and ancient. As you near La Grande, the Blue Mountains of Oregon present volcanic basalt cliffs and ponderosa pine forests.

For local flavor, stop at the historic Occidental Hotel in Buffalo (built 1880, once hosted Butch Cassidy), or the Spoke & Word bookstore in Gillette, housed in an old railroad depot. Along US-16, the tiny town of Ten Sleep (pop. 260) is named after a Native American interpretative marker meaning 'ten sleeps' to a nearby summer camp. Do not miss the Sullivans' family-owned Meadowlark Café in Buffalo for homemade pies; it's a local institution.

Modern interstates are well-maintained, but on two-lane sections, watch for wandering wildlife—deer and elk are common at dawn and dusk. In winter, chains may be required on US-16 and I-84; carry a winter emergency kit. For families, consider the free interactive exhibits at the Buffalo Historical Center, or the dinosaur quarries near Thermopolis (a 2-hour detour). Pets are welcome at most rest areas and outdoor attractions, but keep them leashed and check for dog-friendly patios at restaurants.

To avoid fatigue, plan stops every 2 hours at towns like Gillette (mile 140), Moorcroft (mile 170), and Baker City (mile 320). The latter two have fast-food options and shade. If you need a quick nap, pull off at rest areas—they are monitored and patrolled. For a hidden gem, drive a 20-mile detour to the ghost town of Kirwin, located in the Meeteetse area, accessible via a rough dirt road; it's high-clearance recommended.
