More than 250 cows come from neighbouring villages or from further afield (Isère in particular) to summer in this mountain pasture. Here, different races co-exist: Montbéliarde, Charolais, Limousine, Tarentaise… These are cows that do not produce milk and instead are bred for heifers, breeding or meat cows. They arrive at the bottom of the valley, then climb at altitude as the grass grows, before gradually descending again. They are watched over by a herdsman, who will occupy different alpine chalets according to the progression of the herd.
