This long hike between forests and barns offers an unbeatable view of the valley and the Pic du Midi d'Ossau. The “ports” of Castet and Aste are transit areas. With their pastures and barns, they provide a place for the herds to stay before the great transhumance to the summer pastures or the descent to the valley for the winter.
