Description

A magnificent hike on the Pormenaz massif, allowing you to discover all its natural and scenic riches. From the heights of Servoz, not far from Chamonix, reach the Lac de Pormenaz site along this itinerary designed for good walkers.

Straddling the Sixt-Passy and Aiguilles Rouges national nature reserves, the Pormenaz massif is home to a varied natural heritage. This itinerary invites you to discover all its diversity.
The loop begins at the Tête de la Fontaine, above the Gorges de la Diosaz (a natural area of ecological, faunistic and floristic interest) marking its boundary with the Massif des Aiguilles Rouges. The trail leads to the Pormenaz mountain pastures and then to the Chalets de Chavanne Neuve.
You'll then pass beneath the Pointe Noire de Pormenaz, the massif's highest peak at 2323 m, which you can contemplate on your walk.
Then discover Lac de Pormenaz, nestled in the hollow of this peak, in a superb landscape setting with an exceptional panorama of the Rochers des Fiz.
On your descent, you'll follow the course of the Souay torrent, past the alpine chalets of the same name, to reach the hamlet of Le Mont.

Sixt-Fer-à-Cheval / Passy Nature Reserve

Sixt-Fer-à-Cheval/Passy Nature Reserve, the biggest nature reserve in Haute-Savoie, covers a vast region and boasts two impressive glacier cirques (Fer à Cheval and Les Fonts), both bursting with spectacular waterfalls.Sixt-Fer-à-Cheval/Passy Nature Reserve, the biggest nature reserve in Haute-Savoie, is an exclusively limestone universe featuring a wide variety of forms sculpted by erosion: fissures, grooves, etc. It covers 9,000 hectares across different mountain levels: sub-alpine, alpine and nival, from the banks of the Giffre at 900 metres up to the top of Buet culminating at over 3,000 metres. This range of elevations and the diversity of terrains (wet zones, mixed forests, cliffs, grassy areas, etc., offer contrasting habitats that are richly populated with a wide variety of wildlife species. From the forests to the highest peaks, approximately 800 plant species have been recorded in the nature reserve, including 28 different orchids! Sixt forest is dominated by beech and spruce, but only the most compatible plants can be found in the mountain pastures. Because the habitat changes with the altitude, there is a huge diversity of animal species: deer, wild boar, marmot, mountain hare, etc.. Wild animals thrive in the tranquillity of the nature reserve: ibex, bearded vulture, rock ptarmigan and royal eagle.
