Aspen Snowmass's summit reaches 12,510 feet, dropping 4,393 vertical feet to a base at 8,117 feet across 98 runs spread over 3,342 acres near Aspen, Colorado. Terrain splits 48 per cent intermediate, 30 per cent expert, 17 per cent advanced and 5 per cent beginner. Average annual snowfall runs to roughly 230 inches. The resort carries Ikon Pass and Mountain Collective affiliation. Twenty lifts, including ten quad chairs and one six-person chair, serve the mountain alongside one double chair, two gondolas, four surface lifts and two t-bars.

Snowmass is the largest of the four mountains within the Aspen Skiing Company portfolio by a considerable margin, and its scale and terrain variety have made it a genuine family and destination-skiing counterpart to the more specialised Aspen Mountain and Highlands. Its considerable 4,393-foot vertical drop ranks among the largest of any American ski resort.

The Aspen Skiing Company, founded in 1946 by Friedl Pfeifer, Walter Paepcke and their partners, opened Snowmass, then known as the Snowmass-at-Aspen Ski Area, in 1967, more than two decades after the company's original Aspen Mountain operation. This later development gave the company a considerably larger, more varied fourth mountain to complement its original downtown-adjacent terrain.

Aspen Skiing Company ownership has remained with the Crown family of Illinois since the mid-1980s, following the company's 1977 sale to Twentieth Century Fox. Snowmass continues to anchor the broader Aspen Skiing Company portfolio as its largest and most family-oriented mountain. Adult daily tickets run from 189 to 259 US dollars.
