Buttermilk

Of the four mountains covered by a single Aspen Snowmass lift ticket, Buttermilk carries the reputation as the place most local skiers learned first. Art Pfister developed the ski area in 1958 on a shoulder of land in Pitkin County roughly halfway between the town of Aspen and Snowmass Village, and Aspen Skiing Company has run it ever since as the accessible counterpart to Aspen Mountain’s steep in-town runs and Aspen Highlands’ hike-to bowls. The mountain divides into three distinct zones: West Buttermilk, gentle terrain built for first-timers; Main Buttermilk, the bulk of the cruising runs; and Tiehack, the one section with real pitch and moguls.

From a base at roughly 2,402 meters to a top near 3,012 meters, Buttermilk covers 610 meters of vertical across eight lifts — four chairlifts, a drag lift, a rope tow, and two magic carpets — serving 50 runs and nearly 41 kilometers of trail. The terrain mix tilts toward easier skiing: about 10 kilometers of green terrain and another 4 of novice-rated trail sit alongside 15 kilometers of blue and 11 of black, a split that backs up the mountain’s long-standing name as one of the better places in North America to learn. The Hideout, a dedicated children’s learning center for skiers as young as two and a half, reinforces that reputation, as does Fort Frog, a play area built into the base terrain.

Buttermilk’s other identity runs in the opposite direction. It hosts X Games Aspen, drawing close to 100 of the world’s top freestyle and snowboard athletes to terrain parks built for slopestyle and superpipe competition, nothing beginner about that side of the mountain. Getting there is straightforward: Aspen-Pitkin County Airport sits about 3.5 kilometers away, with Eagle County Regional roughly 50 kilometers off as a backup and Gunnison-Crested Butte Regional about 73 kilometers out. Front Range cities like Lakewood, Boulder, and Arvada sit around 165 kilometers away, a drive of three hours or more over mountain passes, which keeps Buttermilk’s crowd weighted toward destination skiers flying into Aspen rather than day-trippers from Denver.

Broken into exact categories, Buttermilk’s 40.88 kilometers of trail splits into 15.14 km intermediate (about 37% of the mountain), 11.44 km advanced (28%), 10.09 km easy (25%), and 4.21 km novice (10%), a mix that keeps genuine cruising terrain available without eliminating the pitch on Tiehack entirely. The eight-lift network itself skews toward lower-capacity machines built for a learning-focused hill rather than high-volume advanced skiing: four chairlifts anchor the mountain, backed by two magic carpets serving the Hideout and West Buttermilk beginner zones, plus a single drag lift and one rope tow. Lift access here isn’t sold separately from the rest of Aspen Snowmass — season passes and most day tickets bundle across all four mountains — reinforcing Buttermilk’s role as the complementary, beginner-oriented piece of a system built primarily around Aspen Mountain’s steeper in-town runs.

Ranked against its three Aspen Snowmass siblings, Buttermilk’s 610-meter vertical sits well below Aspen Mountain’s steeper descent and Snowmass’s much larger figure, consistent with its role as the entry-level mountain in the shared lift-ticket system. Its 50 runs average out to about 820 meters apiece across the 40.88 total kilometers, a middling length among Colorado resorts of this size. The 2,402-meter base elevation alone sits higher than the summit of many eastern US ski areas, a reminder that Rocky Mountain base villages often start where lower-elevation regions’ mountains end.
