The Monterosa Ski is an Italian ski resort, at the foot of Monte Rosa the second tallest mountain in the Alps, which links three valleys, located largely in the Aosta Valley and the remainder in Piedmont.

Much of the area consists of easy and intermediate skiing, but the area around the Passo dei Salati and especially the steep slopes in Alagna Valsesia are a major and very famous destination for freeride skiers and snow-boarders.

The area takes its name from the huge and spectacular Monte Rosa massif as the heads of its three constituent valleys are located within this group.

One can reach Frachey (Ayas), then Alagna Valsesia and back within the same day using only the lifts.

They operatate a diverse range of ski lifts: funicular, funifor (Funifor Pianalunga - Passo dei Salati), cable car, ski lift, treadmill and chairlift (two-seater, three-seater, fixed-grip quad chairlift or automatic) are the different types of plants lifts that make up the district.
