The first of the four (Aspen Highlands, Snowmass, Buttermilk and Aspen Mountain) Aspen Mountain is the older sibling to the family of Aspen resorts, so show some respect! It’s easy to fall in love with this resort. It’s smaller, more intimate, easier to get to know and basically an all around good time. The people at AM do their part to make sure their superb ski area doesn’t go to their heads. They make an effort of keeping true to their roots, and skiers and riders of this mountain get the feel of an old-school ski area with all the modern amenities.
