Aspen Skiing Company
Lonely Planet review
OK, the top winter activity is pretty much a given: snow riding, and lots of it. The Aspen Skiing Company operates the area's four ski resorts. Aspen (or Ajax) is an athlete's mountain, offering more than 3000ft of steep vertical drop. Aspen Highlands has outstanding extreme skiing and breathtaking views. Buttermilk Mountain provides gentle slopes for beginners and intermediate skiers. Snowmass offers mixed terrain and boasts the longest vertical drop in the USA (4400ft).
