Road Trip Guide: Spearfish SD to Lander WY

Spearfish, SD and Lander, WY sit 280 miles apart along a route that ascends from the Great Plains into the Rocky Mountains. The drive typically takes 4.5 hours without stops, but the real value lies in the journey itself. This guide covers everything from Natural Landscapes to fuel costs, ensuring you don't miss what matters.

US-14 and I-90 West form the backbone of the trip. You'll cross the Wyoming border near Sundance, then follow US-16 through Buffalo and Ten Sleep. The landscape transitions from Black Hills pine forests to high desert Badlands, then to the Wind River Range's granite peaks.

The route passes through the Bear Lodge Mountains, part of the Black Hills, where you'll see Devils Tower—the first UNESCO World Heritage Site in the U.S., designated in 1906. The tower is a 1,267-foot laccolith, a volcanic intrusion that never erupted. Nearby, the town of Hulett offers rustic cabins and a small museum.

Further west, the Bighorn Mountains rise dramatically, with Cloud Peak Wilderness offering alpine lakes and hiking. The Ten Sleep area is named for the Native American counting system; the canyon cliffs are a climbing paradise. Local commerce thrives in Buffalo, where you can visit the Occidental Hotel, a restored 1880s landmark.

For a stunning detour, turn left onto WY-32 at Ucross to reach the Ucross Foundation, an artist retreat. The nearby town of Clearmont is a true time capsule with a working grain elevator.

Fuel stations cluster every 50-70 miles along I-90 and US-16. Gas prices in Wyoming average 10-15 cents per gallon lower than in South Dakota. Budget around $45 for a full tank in a standard sedan.

• Open 24/7 truck stops in Sundance and Gillette.
• Ten Sleep's only fuel station closes by 8 PM; fill up earlier.
• US-16's Teton Pass is closed in winter; check conditions.

Road quality is generally good, but watch for frost heaves near Buffalo and loose gravel on secondary roads. Cell service drops between Buffalo and Ten Sleep; download offline maps.

Winter storms can dump snow unexpectedly as late as May. The route's highest point is Granite Pass (9,033 feet) on US-14, which is sometimes closed. Always carry tire chains and extra water.

• Designated rest areas at Gillette and Buffalo offer picnic tables and clean restrooms.
• For families, the Bozeman Trail Museum in Buffalo has interactive exhibits.
• Pet owners: Most motels along I-90 allow dogs, but check ahead for size limits.
• Fatigue: Run by the numbers, but stop every 2 hours; the high altitude can cause fatigue.

Hidden gem: the Castle Gardens Petroglyph Site, 45 minutes south of Ten Sleep, features hundreds of ancient carvings. It's a short walk from the parking lot and a perfect stretch point.

For a meal, try the Cowfish in Buffalo, known for its bison burgers, or the Lander Bar, a historic 1912 saloon. For coffee, don't miss the Wind River Roasters in Lander.
