Big Sky Resort in Montana offers you three mountains graced by over 400 inches of annual snowfall to delight skiers and snowboarders. Our signature Lone Peak rises to a lofty 11,166 feet with European-style expert terrain accessed by the Lone Peak Tram. Andesite Mountain has some of the resort's most notable intermediate trails, some comfortable south-facing beginner trails, several expert tree runs and a giant half-pipe and terrain park with rail slides. Flat Iron Mountain is on the eastern shoulder of Andesite and offers even more variety.
