The leaves are turning. The temps are cooling down. You’re in top shape from a summer of action. It’s time to enjoy the most brilliant season in the Colorado mountains.

Summer is slipping away, but don’t despair. Hillsides alight in fiery red, burnt orange, and glimmering gold up the “wow-factor” of already incredible Colorado adventures. Welcome the cooling temps and the shorter days by exploring our favorite spots so you can get the most out of this pumpkin-apple-flannel-filled season.

PEDAL THE ASPENS

No spot shows off fall colors and delivers world-class singletrack better than Crested Butte’s Kebler Pass. Two outstanding trails, Kebler Wagon Trail #606 and Dyke Trail #838, roll through one of the state’s largest aspen stands. It may be just a little over five miles long, but the Dyke Trail delivers all the action a mountain biker can handle. Or you can rack up some gravel-grinder miles and explore the 30-mile Kebler Pass Road (CO 12), a sweet mellow gravel route that tops out at 10,000 feet along its picturesque journey from CB to Highway 133 near Paonia Dam (it also makes for a stunning, chill scenic drive). Either way, you will find yourself in the midst of those aspens.

Closer to Denver, the 30-plus miles of challenging riding on the Colorado Trail from Kenosha Pass to Breckenridge has it all: lung-busting climbs, giggle-inducing descents, techy rock sections and fast flowy miles. Add in panoramic views, a high point of 12,000 feet on Georgia Pass, and stands of radiant aspens, and it makes for a classic, must-do autumn ride.  

BAG PEAKS

Summer weekends on a fourteener can feel more like a trip to the mall than the wild. But come fall, you can find more solitude, peace, and quiet on even the most popular peaks. Before early season snows come, tackle the East Slopes route on Snowmass, a 23-mile journey that gains 5,700 feet and rambles through miles of stellar, brilliantly colored aspens.  Sleep serenely under the stars at Snowmass Lake before making a push for the top, which includes a solid section of fun Class 3 scrambling to reach the 14,092-foot summit.  Another autumn favorite is Mount Holy Cross, the Sawatch Range’s northernmost fourteener. The 11-mile roundtrip via the North Ridge route to the 14,005-foot summit climbs through tranquil forest and offers stunning views of massive walls of flawless granite, the Gore Range and hillsides enveloped in seas of amber, crimson and orange. 

WATCH WILDLIFE

With fall comes mating and migration—and the ideal time to spy many of Colorado’s wild inhabitants. From the mountains to the plains, stunning colors and sweeping vistas also make this time of year perfect for unforgettable memories and capturing unique photos. In wildlife-rich Rocky Mountain National Park (rmnp.org), the elk rut, or mating season, peaks from mid-September to mid-October. During this time, more than 3,200 resident elk dominate the park and town. Hear bulls bugle, watch them lock antlers and vie for female attention, and enjoy watching dozens (or even hundreds) of these majestic creatures congregate together in meadows fringed with remarkable mountain scenery and radiant fall colors. Don’t miss Elk Fest (September 29-30), a free celebration complete with bugling contests and elk-inspired exhibits, arts and crafts and activities; visitestespark.com/events-calendar/special-events/elk-fest/

EMBRACE THE SEASON

No fall is complete without a foray into some of the season’s most beloved customs. Actively partake in the harvest with a stop at one of the state’s countless apple-picking spots. At the 100-year old Ya Ya Farm and Orchard (yayafarmandorchard.com) in Longmont you can pick a bag of apples, press your own cider, feed farm animals, and enjoy a hay ride. At Hotchkiss’s Delicious Orchards (bigbs.com), which is also home to Big B’s cider-makers, you can stock up on apples in the shadow of Mount Lamborn, sip a cold hard cider in the taproom, and bring home other fresh veggies and fruits from the garden.

Experience the scarier side of the season by exploring the state’s plethora haunted spots. Take a night spirit tour and learn about the “active” phenomena and spirit folklore surrounding the 100+ year-old Stanley Hotel (stanleyhotel.com), the famed setting for the interior shots (including those creepy twins and the furries in The Shining), in Estes Park. Or, check out the Molly Brown House (mollybrown.org) in Denver. Visitors and staff alike report seeing ghosts roam the house, while others often smell pipe smoke, which was a habit of JJ, Molly Brown’s husband 

There’s not shortage of festivals celebrating autumn in Colorado. Chief among them Mountain Harvest Festival in Paonia (mountainharvestfestival.org), September 27-30. The annual celebration of local music, art, farms, food and spirits is organized by the nonprofit organization Mountain Harvest Creative and highlights the music of the North Fork Valley, local arts and crafts and fun activities like the Great Chili Cookoff, Grape Stomp, Farm Tours and Saturday Sundown Swing. At Applefest in Cedaredge (cedaredgchamber.com), October 6-7, you can pick your favorite fruit and enjoy the music. Denver’s Oktoberfest (thedenveroktoberfest.com) puts a Colorado turn on the classic Bavarian beer weekend. And if you appreciate drawl and tall tales, turn your reins to the Durango Cowboy Poetry Gathering (durangocowboypoetrygathering.org), October 4-7. The four-day celebration of cowboy culture that includes performances by dozens of cowboy poets, storytellers and musicians, western art displays and a boot-stomping parade.
