Ouray to Pocatello: Epic Mountain Road Trip Guide

The Million Dollar Highway (US 550) north of Ouray was carved in the 1880s by Otto Mears, a toll road builder known as the 'Pathfinder of the San Juan.' This route from Ouray, CO to Pocatello, ID spans about 560 miles and typically takes 9-10 hours of driving time without stops. The road crosses the Continental Divide at Red Mountain Pass (11,018 ft) and descends through the Colorado Plateau, Utah's Wasatch Range, and finally the volcanic plains of Idaho. A must-read is how to find the best stops and hidden gems between cities for maximizing your journey.

Is it worth driving Ouray, CO to Pocatello, ID? Yes, if you enjoy diverse landscapes, but plan for fatigue on long desert stretches. Key rest areas: Green River Welcome Center (milepost 150 on I-70) and Brigham City rest area (I-15).

• Pet-friendly: Many motels in Moab and Salt Lake City accept pets; rest stops have designated pet areas.
• Child-friendly: The Living Planet Aquarium in Salt Lake City is a great break, and the Lava Hot Springs in Idaho (off I-15) offer family pools.
• Hidden off-route spot: Goblin Valley State Park (50 miles south of I-70) — a landscape of mushroom-shaped hoodoos with few tourists.
• Fatigue management: Alternate drivers every 2 hours or stop at scenic viewpoints like the one at Red Mountain Pass (milepost 85 on US 550).

This drive transitions from jagged alpine peaks (San Juans) to red rock canyons (Utah) and finally sagebrush steppe (Idaho). The contrast is stark: one moment you're above treeline, the next you're in a high desert. In Moab, Arches National Park boasts over 2,000 natural stone arches; less crowded is Dead Horse Point State Park with views of the Colorado River gorge.

• Culinary highlights: farm-to-table in Moab (e.g., The Peace Tree Juice Cafe), Basque cuisine in Salt Lake City (e.g., The Basque Market), and classic Idaho potato dishes in Pocatello (e.g., The North End Cafe).
• UNESCO World Heritage Sites: None directly on route, but nearby Mesa Verde National Park (2h detour from Durango) is a designated site.

Fuel stations are sparse between Ouray and Moab—gas up in Montrose (20 miles north) before tackling the mountains. After Moab, I-70 and I-15 corridors offer frequent services. Expect higher fuel prices in remote Colorado towns (up to $0.50 more per gallon than in Utah valley cities).

• Road surface: mostly paved and well-maintained, but US 550 has sharp curves and no guardrails in sections. Watch for rockfall.
• Best driving windows: May through October; winter requires chains on US 550.
• No toll roads on this route.
