Beginning in late August each year, the aspens in the highest parts of Rocky Mountain National Park embark on their annual transition of 'quaking'; a term use to describe the leave's behavior in the breeze and unique color changing process from green to brilliant golden yellows, oranges and reds.

If you have yet to visit the park during the fall, you must add it to your to-do list! The hues painting the mountainside change with each passing day until mid to late September, accompanied by the elk's rutting season and migration down from the high country. Tourists, photographers and nearly everyone else believes the park is in it's prime during this time of year, though there are certain spots that are recommended above others if you're chasing colors....

Hidden Valley

Far from hidden, this popular spot is a favorite among wildlife enthusiasts as a place where elk gather in large numbers, backdropped by fiery colors. There are numerous viewing spots along US 34 on the SE facing hillsides. Have your cameras ready! Elk show up with little warning and you may miss the ideal opportunity if you're not prepared...

Glacier Gorge Trail

All the way up to Alberta Falls on Glacier Gorge Trail, you'll be snapping pictures and looking on in awe; this hike is a beautiful one. Aspens line the path and fallen leaves float along the creek, welcoming you with a flurry of color.

Bear Lake Road

This road runs parallel to the Glacier Creek and is worth the time it may take to travel all the way to the end. You'll begin at Moraine Park and will want to pull off the road any chance you get because every turn will offer a new and interesting view! If you'd prefer to hike or relax at an overlook, there are many opportunities along the way for that as well.

Twin Sisters

Because the trail head is located just outside of the park's boundary (approximately 6 miles from Estes Park), this hike is a favorite for those who prefer a more secluded experience. If you've brought your camera along, be sure to get an early start to the day for the best lighting. 

Fairview Curve

About 10,000 feet up on Trail Ridge Road you'll find the Fair Curve and spectacular views of the Mummy Range up to the north. You will have driven through the Kawuneeche Valley to reach this spot, so you can now appreciate the valley's color from above! 

Kawuneeche Valley

Argued by some as the most beautiful place in the park to photograph, you'll drive through 10 miles of Kawuneeche Valley along Trail Ridge Road between Grand Lake and the Timber Lake trail head. Give yourself ample time for stops on this route because it tends to be more lovely than one expects.
