    Tips

    May 5, 2025

    Starting from the historic mining town of Georgetown, the Guanella Pass climb offers you a spectacular journey through dense forests opening into breathtaking high-alpine tundra with views of towering peaks like Mount Bierstadt. You'll ascend approximately 10.5-11 miles, gaining over 3,100ft to reach the lofty 11,669ft summit. Be prepared for a challenging profile: after a steep initial section of 6-7% on average, the gradient eases through the middle before a very tough final 2.3 miles featuring steep switchbacks averaging over 7% with ramps hitting 10-12% or more, made significantly harder by the extreme altitude. The pass is seasonally closed so be sure to check before attempting this climb.
