Aspen's Two Peak Spectacles: Late September's Golden Aspen Foliage & January's Winter X Games

While Aspen is appealing year-round, two specific weeks on the calendar transform the entire Roaring Fork Valley into an memorable spectacle: the Autumn Gold Leaf Peak in the second half of September, and the Winter X Games at Buttermilk Mountain every January.

1. Peak Golden Autumn Foliage in Aspen: 'September 18 to October 4'

Unlike New England (where maples turn in mid-October), Aspen sits at 2,400 to 3,600 metres elevation, meaning its millions of white-barked quaking aspen trees reach peak 24-karat gold during the final two weeks of September (typically 18 September to 2 October). Because an entire hillside of aspens is a single genetic clone connected by one root system, whole mountainsides glow in unison against cobalt-blue skies and the first dusting of white snow on the 14,000-foot peaks. Here are the 4 Best Golden Foliage Drives & Walks in Aspen:

1. Maroon Creek Road & The Crater Lake Trail: book your shuttle or e-bike months ahead for late September.
2. Castle Creek Road to Ashcroft Ghost Town & Pine Creek: 12 miles of continuous golden tunnels with no shuttle permit required.
3. Owl Creek Road & Brush Creek Road (Between Aspen Airport & Snowmass Village): a 10-minute rolling country drive beneath interlocking golden canopies framing Mount Daly.
4. Independence Pass (Highway 82 East) & Driving the 'West Elk Loop' over Kebler Pass (Home to the Largest Living Aspen Clone on Earth).

2. Late January at Buttermilk Mountain: The 'Winter X Games' & December's 'Wintersköl'

• Winter X Games Aspen (Held Late January at Buttermilk Mountain): for over 20 years, Buttermilk has been the home of ESPN's Winter X Games, where Olympic champions compete in the 22-foot SuperPipe, Big Air and Slopestyle. Check current ticket tiers on the official site; daytime skiing on Buttermilk's main trails remains open to regular skiers right beside the X Games venue, and free RFTA shuttle buses run continuously between Rubey Park downtown and the base of the SuperPipe.
• Mid-December or January, 'Wintersköl' (Aspen's Annual 'Toast to Winter' Since 1951): features giant snow sculptures on the downtown pedestrian mall, a soup contest, a torchlight descent down Ajax and fireworks over Aspen Mountain.
