Ouray to Stanley: Ultimate Road Trip Guide through Colorado and Idaho

The drive from Ouray, Colorado to Stanley, Idaho is a 570-mile epic that traverses the spine of the Rocky Mountains. Known as the "Switzerland of America," Ouray sits at 7,792 feet, a historic mining town surrounded by 13,000-foot peaks. Your destination, Stanley, Idaho, is a tiny gateway to the Sawtooth Wilderness, nestled at 6,260 feet along the Salmon River.

One specific local driving quirk: you'll cross the Continental Divide twice—once at Molas Pass (10,910 ft) and again at Indiana Pass on the Million Dollar Highway. The Million Dollar Highway (US-550) between Ouray and Silverton is a thrilling 23-mile ribbon of asphalt with sheer drop-offs and no guardrails. This stretch demands full attention and slow speeds.

You might ask is it worth driving Ouray, CO to Stanley, ID—absolutely, this is one of the most diverse and breathtaking routes in the American West.
