OK, the top winter activity here is pretty much a given: the pursuit of powder, and lots of it. The Aspen Skiing Company runs the area’s four resorts – Snowmass, best all-around choice, with the most terrain and vertical; Aspen, intermediate/expert; the Highlands, expert; and Buttermilk, beginner/terrain parks – which are spread out through the valley and connected by free shuttles.

Both Aspen and Snowmass are also open in summer (lift ticket $22; mid-June to September) for hiking, mountain biking, concerts and activities.
