Aspen to Rock Springs Road Trip: Scenic Drive Guide

Driving from Aspen, Colorado to Rock Springs, Wyoming covers 340 miles and takes approximately 5.5 hours without stops. The route traces the edge of the Rocky Mountains via Highway 82, I-70, and US-191, crossing the Continental Divide at 9,000 feet. Did you know? The town of Rock Springs was once a key stop on the Union Pacific Railroad, and its name comes from a nearby spring used by pioneers.
