Boulder to Dubois Road Trip Guide: Epic Rockies Drive

The route from Boulder, CO to Dubois, WY follows US-287 and US-26, a 440-mile journey through Colorado's Front Range and Wyoming's Wind River Country. A little-known fact: near Rawlins, WY, you cross the Continental Divide at 7,000 feet, where water flows to both the Atlantic and Pacific. This drive typically takes 7-8 hours without stops, but you'll want to allocate a full day to explore. Is it worth driving Boulder to Dubois?

• US-287 from Rawlins north: pristine asphalt, low traffic, but no services for 80 miles.
