Cody WY to Ouray CO Road Trip Guide: High Plains to San Juans

The drive from Cody, Wyoming to Ouray, Colorado spans 540 miles across the spine of the Rocky Mountains. This route, largely on US-20, US-26, US-191, and US-550, crosses the Continental Divide twice.

A quirky fact: near Thermopolis, WY, the highway passes within 200 feet of the world's largest mineral hot spring—a steaming 127°F pool that you can smell before you see. The drive typically takes 9–10 hours without stops, but most travelers stretch it to two days.

Understanding how to find the best stops and hidden gems between cities transforms this journey from a mere transit into a Western odyssey.
