Discover a magical and wild place by following a technical path ... In the heart of the Passy nature reserve, Lac de Pormenaz, with the Fiz mountains as a backdrop, is a must-see summer hike for mountain lovers.
From Plaine-Joux, go up through the resort by the track to reach Barmus, the Ayères des Pierrières then the Souay chalets where you will turn left. Engulf yourself towards the torrent (short descent) and go up via the Chorde to Lac de Pormenaz. Go around the lake to admire the reflection of Fiz or walk along it on the left to join the descent path of Argentières.
Once back at the Souay chalets, continue down the track to reach the Châtelet d'Ayères refuge. Pass over Lac Vert to reach the starting point.
