Each fall, tourists and locals, alike, flock to the mountains in Colorado to see the changing aspen leaves. The days see less hours of sunlight as the autumnal equinox approaches mid-September, making the aspen leaves change due to the decrease in photosynthetic activity. Other factors like precipitation levels, the tree’s stand health, and temperatures throughout Colorado affect foliage colors in the fall. Typically, the best time to catch the colorful display in Colorado is mid-September through early October.
Try taking a road trip through Colorado for the best chance to see a variety of autumn leaf color, including yellow, orange, and red aspen leaves. The best time to take this road trip would be late September for peak viewing times throughout Colorado, assuming the weather will be dry and sunny with cool, but frost-free nights.
Author’s Note: The timing of the color change in foliage varies each year. Click here for the outlook for aspen leaves changing in 2021. When leaf-peeping, be sure to safely pull of a road using a public route and designated pull-offs. Follow the Leave No Trace principles when adventuring in Colorado. Never pick leaves off the aspen.
