The Guanella Pass Scenic Byway is a 22 mile paved stretch of road that runs between U.S. Highway 285 and Georgetown, CO. Guanella Pass Road will take you to an altitude of 11,669 feet or approximately 3,566 meters above sea level. The pass is closed during the winter months, but you’ll find your share of wonderful views during the late-Spring, Summer, and Fall. Be prepared for varying weather conditions. While it may be shorts weather at lower altitude, you may find the temperatures a bit brisk at these higher altitudes. Plus, be sure to pack lots of sunscreen as you can get sun burned very quickly at high altitude as well.
