Mammoth has 3500 acres of trails, covered in 400 inches of snow, bathed by 300 days of sunshine and that’s just the mountain in an average year. 11,053-foot Mammoth Mountain dominates the Eastern Sierra skyline and the minds and hearts of its die-hard skiers and riders. Yes Mammoth is big. And there’s more to Mammoth winter than one mountain: cross country skiing and snowmobiling over acres of pure white; uncrowded powder days at June Mountain; dinner at Lakefront Restaurant. It's all part of the Mammoth experience.
