Colorado in the fall is synonymous with the aspen tree. Colorado's ubiquitous Populus tremuloides (quaking aspen) is a beauty in all seasons, but it is the brilliant yellow (and less commonly) orange & red hues that make this the showstopper of Colorado fall. But the aspen tree is far from the only game in town when it comes to fall color. Colorado's multiple species of cottonwoods turn bright yellow, while urban hardwood trees resemble the spectacle put on farther east in the country. Ash trees and box elders add to the show, while various species of willow pop yellow colors along creek beds statewide. Most hikes are inspired by the recently published guide, Colorado's Best Hikes for Fall Colors by Matt Enquist from the Colorado Mountain Club Press. Observed over three years of writing, Enquist notes, the last week of September and the first week of October have provided reliably beautiful tree color. We will warm-up for the trip with a few hikes in the Front Range near Denver and Breckenridge, providing time and opportunity to acclimatize to the high elevation. We then climb higher in central mountains near Aspen in the middle of large wilderness areas that should be replete in the splendor of Colorado's fall colors.
