Integrated kiosk and website Fortress has a remarkable range of terrain to accommodate all levels of skiers... making us a huge hit with families. The casual and relaxed ski area offers wide-open cruising, serious bumps, larch gladed areas and natural half-pipes popular with snowboarders. Our high base area, 2040m (6,692 ft), receives a dazzling 630cm (21 ft) of dry powder a year.
