Route details
Route description
Reach the splendid Lac d'Anterne in the heart of the Passy Nature Reserve via several emblematic locations: Ayères des Pierrières, Col d'Anterne, Moëde Anterne and Chatêlet d'Ayères refuges, Lac Vert, etc.
This hike is long but relatively accessible. The effort will be more than compensated by the beauty of the places you pass through.
From Passy Plaine-Joux, take the path that goes up towards Barmus and continue along the track towards Ayères des Pierrières.
Reach the Col d'Anterne and descend to the lake of the same name in a breathtaking natural setting.
Retrace your steps to reach the Moëde Anterne refuge and the Argentières (some tricky passages).
Continue your descent towards the Chalets du Souay, Ayères du Milieu, the Châtelet d'Ayères refuge, before arriving at the heights of Lac Vert, another natural wonder on the route.
Then return to Passy Plaine-Joux to complete the route.
Please note: Mountain lakes are fragile ecosystems. It is best not to swim in them. The addition of organic or chemical matter (sunscreen, buoys, etc.) profoundly alters their functioning.
The Passy nature reserve is a protected and regulated area. Dogs, even on a leash, are prohibited, as well as motor vehicle traffic, fires and overflight, including drones. The bivouac is tolerated from 19 p.m. to 9 a.m.
