Much of this resort's appeal relies on its meticulous grooming of modest fall-line faces free of traffic. When the wind howls atop nearby Echo Summit, Sierra's front side becomes a catcher's mitt for powdery snow. Riders can enjoy "The Gauntlet," a terrain park containing tabletops, gap jumps and more. The parks aren't restricted to just one area, they span the entire mountain. Five terrain parks and a 485-foot half pipe attract a sometimes rowdy young crowd, but there's plenty of snow and elbow room to go around at the 2000-acre resort, which averages 560 inches of snowfall annually.
