We publish a trail map only once we have checked it against the resort's own file, and we do not yet have a verified map for Mammoth Mountain. Most resorts release the new season's map between October and December, so this page will fill in as winter approaches. In the meantime, Mammoth Mountain has 150 trails and 28 lifts, running from 7,949ft to 11,053ft.
