Skiing & SnowboardingTwo mountains, 3,400-vertical feet, more than 2,000 acres of terrain and the highest per-hour, per-skier lift capacity anywhere on earth. Translation: Sun Valley is crowdless skiing and riding at its best. It’s the home light, fluffy powder, as well as the largest automated fleet of snow making machines in the United States. Steep bump runs are as common as perfectly manicured blues. Families love the themed Adventure Trails. And at the Dollar Mountain Progression Park, the sky is filled with twisting, flipping, crashing beginners, intermediates and pros.
