At the church square, follow the Evançon torrent and turn left onto Rue de l'Ostrion, which gradually climbs. Do not take the Mascognaz waterfall on the left, but continue on the path straight ahead.
Pass by the small chapel overlooking the village of Champoluc and the Ayas Valley. You will reach the village of Mascognaz, an authentic and beautiful Walser village. Continue towards Col de Palasina. (Do not take the path on your left that passes through the hamlet of Chavannes and Lake Perrin) butstay on the path towards Praz-Sec, still heading for Col de Palasina at an altitude of 2,661 metres. The climb is now over. A gentle descent will take you to the wild Bataille lakes and then to the Arp refuge at 2,400 metres.
