Ouray to Riverton Drive: Epic Colorado-Wyoming Road Trip Guide

The 295-mile drive from Ouray, Colorado to Riverton, Wyoming, traverses the Million Dollar Highway and the sagebrush steppes of the Great Divide Basin. This route, primarily US-550 and US-191, climbs over Red Mountain Pass (11,018 ft) before descending into the high desert. The journey takes approximately 5.5 hours of pure driving, but plan for 7-10 hours to explore.

Historical marker: The Ouray area was home to the Ute tribe, and the town was founded as a silver mining camp in 1875. The Million Dollar Highway (US-550) was originally a narrow-gauge railroad route. Today, it's a twisty, unpaved shoulder road that demands attention.
