Fall in Colorado 2025: When & Where to See the Best Fall Colors

Fall is the only time of year when Mother Nature transforms the entire landscape so dramatically—and what a sight it is! Across the state of Colorado, vibrant hues of gold, amber, and crimson replace summer’s emerald greens, drawing locals and visitors alike outdoors. Whether you’re looking for alpine views, glowing aspens, or scenic drives, fall colors in Colorado are something you have to experience at least once.

Why Do Leaves Change Color in the Fall?

Shorter days and dropping temperatures trigger the change in leaf color. As sunlight decreases, trees produce less chlorophyll, the compound responsible for green leaves. As chlorophyll fades, natural pigments like carotenoids and anthocyanins become visible, revealing beautiful shades of yellow, orange, and deep red. The sugar content in leaves can also intensify red and purple tones.

When Will Colorado’s Leaves Change in 2025?

Leaf peepers can expect another stunning fall season in Colorado. According to past trends and projections from SmokyMountains.com, Colorado’s fall colors will likely begin to turn in mid-to-late September, with peak foliage lasting into the third week of October.

• High elevations (above 9,000 feet) could see color changes by mid-September.

• Lower elevations, like Denver and the Front Range, will peak around early to mid-October.

• Expect northern ranges (like the Mosquito and Tenmile) to change first, with southern ranges (such as the San Juans) peaking later in October.
