The Summit County resort is 100 percent open, including the East Wall. Snow has been great this year, with 63 inches of snow in February, 20 inches more than last season. Arapahoe Basin is expected to stay open into mid-June, depending on the snow conditions. The best thing about A-Basin in the springtime is the "Beach," which sits alongside the slopes in the base area parking lot. People come prepared with lawn chairs, BBQs, food, and fun for super spring skiing and riding in the Rockies.
