Whistler Blackcomb in Canada has a larger ski area and dozens of European ski regions appear to have more ski pistes than Vail, but comparison is difficult as Europe's areas measure ski runs by their length, North American by area.
Vail Resort is entering "phase two of its grooming initiative" which means it will manicure thirty percent more terrain each night. It is adding nine new grooming machines for this winter in order to achieve this ambitious target. On average the resort will groom 1,300 to 1,600 acres oper night--a larger area than most U.S. ski resorts offer in total. \
