When is the Best Time to See Fall Colors in Estes Park in 2026?
If you’re planning a fall trip to Estes Park, Colorado, mid-September through early October is generally the best window for seeing fall colors, with peak color around Estes Park often occurring in the second half of September.
If we had to pick a time to come…
There isn’t one guaranteed “peak week.” Aspen leaves change according to elevation, temperatures, moisture, and other weather conditions, so timing varies from year to year. Higher elevations in Rocky Mountain National Park typically begin changing first, followed by the lower elevations around Estes Park.
That makes September 15 through September 30 an excellent window to plan an Estes Park fall getaway if colorful aspens are a priority.
And there’s a bonus: September is also elk rut season, making fall one of the most memorable times of year to visit Estes Park and Rocky Mountain National Park.
Where Are the Best Fall Colors in Estes Park?
You don’t have to look far. Golden aspens can be found throughout Estes Park and Rocky Mountain National Park, but some areas are particularly beautiful during September.
Here are a few of our favorite ways to experience fall colors:
Drive Trail Ridge Road in Rocky Mountain National Park
One of the most spectacular fall drives near Estes Park is Trail Ridge Road.
The 48-mile road crosses Rocky Mountain National Park between Estes Park and Grand Lake and reaches an elevation of 12,183 feet. Along the way, you’ll travel from forests and colorful aspen groves into the alpine tundra above tree line.
Because of the dramatic elevation change, Trail Ridge Road also provides an opportunity to see several different stages of fall during the same drive.
Important: Weather changes quickly at these elevations, and an early-season snowstorm can temporarily close portions of Trail Ridge Road. The road typically closes for the winter sometime in October, depending on conditions. Always check current Rocky Mountain National Park road conditions before setting out.
Other Scenic Fall Drives Near Estes Park
Two other excellent drives for fall foliage are:
Old Fall River Road – This historic one-way gravel road climbs through forests and mountain scenery toward Fall River Pass and the Alpine Visitor Center. It’s a wonderful choice for a slower-paced fall drive, but seasonal and weather-related closures are possible.
Peak to Peak Scenic Byway – For a longer excursion outside the park, head south from Estes Park toward Allenspark and Nederland. The route passes mountain peaks, historic communities and beautiful stands of golden aspens.
Best Fall Hikes Near Estes Park
Want to experience the aspens on foot? September’s cooler temperatures make it an excellent month for hiking in Rocky Mountain National Park.
Gem Lake
Distance: About 3.4 miles round trip
Trailhead: Lumpy Ridge
Difficulty: Moderate
The hike to Gem Lake combines rock formations, mountain views and colorful fall vegetation. Along the way you’ll get excellent views overlooking Estes Park and toward Longs Peak.
Because Lumpy Ridge is part of Rocky Mountain National Park, remember that timed-entry requirements may apply during certain hours in September.
Bierstadt Lake
Distance: Distance varies depending on starting point
Difficulty: Moderate
Bierstadt Lake is particularly beautiful in fall, when golden aspens contrast with views of the Continental Divide.
You can reach Bierstadt Lake from the Bierstadt Lake Trailhead or from the Bear Lake area. If you’re entering the Bear Lake Road Corridor during reservation hours, you’ll need the appropriate Timed Entry + Bear Lake Road reservation.
The Pool
Distance: About 3.4 miles round trip
Trailhead: Fern Lake Trailhead
Difficulty: Moderate
The hike to The Pool follows the Big Thompson River through a mix of forest and aspen. It’s a great choice for visitors looking for a relatively short fall hike with plenty of classic Rocky Mountain scenery.
When Should I Visit Estes Park for Fall Colors in 2026?
If fall foliage is the main reason for your trip, we recommend planning for mid- to late September, particularly September 15–30.
Come earlier in that window and you may find the best color at higher elevations. Come later and the color may be more pronounced around Estes Park and at lower elevations.
Of course, Mother Nature gets the final say!
The good news is that there’s much more to an Estes Park fall vacation than leaves! September also brings crisp mountain mornings, comfortable hiking temperatures, abundant wildlife and the unmistakable sounds of bull elk bugling during the annual rut.
Our advice: Give yourself several days in Estes Park, explore different elevations, and don’t try to predict one perfect “peak” day. Fall in the Rockies changes quickly—and that’s part of what makes it so spectacular.
