There are approximately 180 km of ski slopes (almost all equipped with snow-making), from the most simple to the more technical (19 blue runs, 41 red runs and 6 black runs, including, in Gressoney-Saint-Jean, the most difficult of the whole Aosta Valley), and 38 lifts that start at a minimum altitude of 1212 m above sea level (Alagna) and reach up to 3275 m s.l.m. at Indren Peak.
