Aspen start turning in late August at higher elevations and the golden leaves work their way down to lower elevations in October.
The peak of the fall color gold rush in this Rocky Region is usually in late September.
Daylight and elevation set the timing of the color season. Rain, snow, cold and wind affect the intensity of color.
Bear Lake Road, the Peak to Peak National Scenic Byway, the Cache la Poudre National Scenic Byway and the Colorado River Headwaters National Scenic Byway are favorite drives for fall color.
The Little Horseshoe Park area is a hidden treasure in Rocky Mountain National Park. It is not a heavily traveled area, although trails run into the large meadow from Horseshoe Park and Deer Ridge Junction. It is a great place to view both bugling elk and changing aspen in the fall months.
