The end of the summer season is marked in Valle d'Aosta with a traditional occasion dear to the locals: la désarpa. After a long summer spent in the mountain pastures at high altitude, at the foot of the highest peaks in Europe, the cows come home to graze at the bottom of the valley.

Désarpa day traditionally coincides with the feast of St. Michael, so each year, on the 29 September, the moving of cattle represents an important moment in the life of breeders, as well as a day of celebration to share with everyone.
