Discover more about Guanella Pass

Guanella Pass is more than just a road; it's a journey through the heart of the Colorado Rockies. This scenic byway, a paved 22-mile stretch, follows an old wagon trail used by miners in the 1860s, linking the historic towns of Georgetown and Grant. The pass was named in 1953 after Byron Guanella, a road supervisor and commissioner in Clear Creek County for nearly 50 years. As you ascend, the landscape transforms from lush forests of lodgepole pine, spruce, and fir to the unique alpine tundra, where hardy vegetation thrives in harsh conditions. Wildlife is abundant, with opportunities to spot bighorn sheep, mule deer, and various bird species. The pass is particularly stunning in the fall when the aspen trees display their vibrant autumn colors. Guanella Pass offers a variety of recreational activities. Hiking trails abound, with options for all skill levels, including access to Mount Bierstadt, a popular fourteener. Camping is available at designated campgrounds and dispersed sites, allowing you to immerse yourself in the natural beauty. In winter, the road is closed to vehicular traffic beyond certain points, transforming it into a haven for snowshoeing and cross-country skiing. The pass also provides a glimpse into Colorado's mining history. Georgetown and Silver Plume, located near the northern end of the pass, are well-preserved Victorian towns that boomed during the silver rush. Visitors can explore historic sites, ride the Georgetown Loop Railroad, and learn about the challenges and triumphs of the early miners.
