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. Big Sky has a total of 3,812 expansive acres, 4,350 jaw-dropping vertical feet and over 150 named trails. Our reputation for short or non-existent lift lines makes this truly a place all your own. We hope you'll experience it for yourself this winter. Now with the option of the Lone Peak Pass, the combined total with Moonlight is 5,512 acres!
