If there's anything more embarrassing than face-planting off a rail in front of a full chairlift, we don't want to make that mistake, either. The truth is, the intimidation factor cannot be overstated when it comes to terrain parks, and so we fully appreciate the lengths to which Keystone Resort keeps going to help riders and skiers get better the right, and easy, way. Enter A51, the name for the resort's six terrain parks in one sixty-acre area, with lines that lead from beginner to expert, all served from one dedicated lift. With 116 features and more on the way, the park offers extra-small, small and medium features — a variety of pipe sizes, along with boxes, barriers, rails, ramps, tubes, tables, jibs and jumps — plus a staggering selection of big ones, with each skill level smoothly transitioning to the next. Start extra-small on Easy Street, then head to I-70 and the Alley, with their slightly larger features. By the time you hit the hardest area, Main Street, you'll be ready to go pro.
