During winter, people downhill ski and snowboard at the challenging but historically relaxed Alpental Ski Area (part of The Summit at Snoqualmie ski resort). Recent additions by Booth Creek Holdings have added gas fire pits, heated sidewalks and other human comforts. While most of the mountain is skiable by intermediate and advanced skiers, the cliff areas are the roughest skiing terrain in the state, and must only be attempted by very experienced skiers. The expert run International is well-known among Puget Sound area skiers and snowboarders, and has been affectionately nicknamed "Nash." The ski area is served by four chair lifts and a magic carpet on the west side of the valley beneath Denny Mountain. People backcountry ski, snowshoe and ice climb in Alpental Valley using the upper parking lots, traditionally known as lots 3 and 4, as a starting point.
