Spokane to Pinedale Road Trip: Scenic Drive through Idaho & Wyoming

Did you know that the drive from Spokane, WA to Pinedale, WY crosses the Continental Divide twice? This route, primarily via I-90 east then US-287 south, covers roughly 700 miles and takes about 11-12 hours of pure driving time. It passes through the rugged Bitterroot Range and the high plains of Wyoming, offering a mix of mountain vistas and sagebrush deserts.

Because the route spans three states and multiple time zones (Pacific to Mountain), careful planning is essential. The how to find the best stops and hidden gems between cities approach ensures you don't miss the unexpected, like the ghost town of Burke, ID or the free hot springs near Lava Hot Springs.

The most efficient route is I-90 east from Spokane to Butte, MT, then I-15 south to Idaho Falls, ID, and finally US-26/US-189 east to Pinedale, WY. An alternative scenic route is US-12 through Lolo Pass, which adds time but offers stunning views.

Key highways: I-90 (WA/MT), I-15 (MT/ID), US-26/US-189 (ID/WY). Road quality is generally excellent, but winter conditions can be harsh, especially over Lookout Pass (MT) and Teton Pass (WY).

• Total distance: ~700 miles
• Pure driving time: 11-12 hours
• Best with 2 overnight stops
• Fuel stations: frequent along interstates, sparse on US-189 in Wyoming

Fuel stops: Major towns include Coeur d'Alene (ID), Missoula (MT), Butte (MT), Idaho Falls (ID). In Wyoming, fuel up in Jackson or Pinedale; stations are 50+ miles apart after Jackson.

Consider a fuel strategy: fill up when you hit half a tank, especially after Butte and before entering Wyoming. Diesel is available at most truck stops.

The route transitions from the pine forests of eastern Washington to the craggy Bitterroot Mountains. Lookout Pass at the MT/ID border offers a dramatic ascent. Once in Montana, the landscape opens into vast valleys with glimpses of the Anaconda Range.

In Idaho, the Snake River Plain stretches south of Idaho Falls, a volcanic landscape dotted with lava fields. Approaching Wyoming, the Wind River Range appears on the horizon, culminating in the Gros Ventre Wilderness near Pinedale.

• Key landscapes: Coeur d'Alene Lake, Bitterroot Range, Big Hole Valley, Craters of the Moon (detour), Wind River Range
• Hidden gems: Berkeley Pit (Butte, MT), Lava Hot Springs (ID), Sinks Canyon State Park (WY)

Local commerce along the route reflects the region's history. Butte's historic uptown district features old mining saloons and the World Museum of Mining. In Idaho Falls, the farmer's market (summer Saturdays) showcases local produce and crafts.

Near Pinedale, the Museum of the Mountain Man details fur trade history. The Green River Brew Depot in town serves locally roasted coffee and craft beer.

Safety is paramount. Watch for wildlife, especially deer and elk at dawn/dusk. In winter, chains may be required over passes. Always carry emergency gear: blanket, food, water, flashlight.

Road quality: I-90 and I-15 are well-maintained. US-189 in Wyoming has some narrow sections and frost heaves. Cell service is spotty in mountain stretches.

• Rest zones: Rest areas every 30-50 miles on interstates. In Idaho, rest stops are basic but clean.
• Fatigue management: Plan to stop every 2-3 hours. Good stops for a break include the Lookout Pass Ski Area (summer hiking) and the St. Regis Travel Plaza (MT) with a casino.

Family and child suitability: Kid-friendly stops include the Wolf Education and Research Center (Winchester, ID), and the Idaho Falls Zoo at Tautphaus Park. The drive itself offers plenty of window-gazing scenery, but pack entertainment for long stretches.

Pet-friendly framework: Most motels along the route accept pets (e.g., Super 8, La Quinta). National forests allow leashed hiking. Butte's Dog Park is a good run area. Always carry water and shade.
