NOTE: For years the high alpine bowls at Keystone have loomed above the lifts, accessible only to those willing to hike to the top. That has changed with the Bergman Express, Keystone’s high-speed six-passenger chairlift, unlocks the sweeping faces and glades of Bergman Bowl, more than 550 acres of above-tree line terrain for intermediates and experts alike.
