Wintersköl (Mid-January). Aspen's tongue-in-cheek 'toast to winter' — parade, fireworks, and canyon-wide festivities.
X Games Aspen (Late January). Free-to-attend action sports and concerts at Buttermilk — one of the biggest events of the winter.
Ski & ride season (four mountains) (Late Nov – mid Apr). Aspen Mountain, Highlands, Buttermilk, and Snowmass on one pass — from mellow groomers to legendary steeps.
Food & Wine Classic (Mid-June). The country's premier food-and-wine festival — tastings, seminars, and celebrity chefs.
Aspen Music Festival & School (Late June – Aug). Eight weeks of world-class classical performances across town, many free.
Golden aspens (Mid-to-late September). The hillsides turn brilliant gold — peak leaf-peeping on Independence Pass and around the Maroon Bells.
