You might consider going to Gressoney which is one valley west of Alagna, but is connected via lifts to Alagna as well as to Champoluc (next valley west of Gressoney). The area is not as snow sure as some, but Gressoney starts from a higher base than Alagna and you can get to the snow by staying high. There's a ton of pisted, lift served skiing across the Monterosaski area. If the conditions are favorable, there are unlimited off piste options. Check in with Carlo Cugnetto in Gressoney, www.guidemonterosa.com
. They can do a variety of off piste combinations of lift served, touring and or/heli-ski. Carlo's family runs a very nice hotel at the bottom of the lifts in Gressoney which makes for a great base to work from. They do a great one or two day trip to Zermatt and back using helicopters and lifts, all off piste. A bit out of the way and very uncrowded; Gressoney gives you access to some amazing terrain and huge verticals.
