Glenwood Springs to Rock Springs Road Trip Guide

The drive from Glenwood Springs, Colorado (elevation 5,761 ft) to Rock Springs, Wyoming (elevation 6,271 ft) covers 226 miles along I-70 and US-191, a route that follows the old Lincoln Highway and crosses the Continental Divide at Rabbit Ears Pass (9,426 ft). A little-known fact: this corridor parallels the historic Union Pacific rail line, and near Point of Rocks, Wyoming, you'll pass the remnants of a Pony Express station dating to 1861. Most travelers underestimate the sheer variety of ecosystems – from hot springs and river valleys to alpine meadows and high desert badlands – packed into a mere 3.5-hour drive without stops.
