Passy

Réserve Naturelle Nationale de Passy

Facing the Mont-Blanc massif, the Passy Nature Reserve dominates the Arve valley.
A real gem of nature, it connects the Sixt-Fer-à-Cheval and Aiguilles Rouges Reserves.
Area: 1800 ha
Altitude: 1300 to 2900 m
The Passy Nature Reserve sums up the mountain history of Haute-Savoie:
– the natural environments: the young cliffs of Fiz dominating the sheep hills of old Pormenaz, the formidable thrust of the Alps opposing their siliceous and limestone nature. From this mineralogical contrast was born the diversity of environments (lawns, moors, wetlands) and alpine species (ibex, eagles, etc.)
– wildlife: chamois, ibex, eagle, marmot, grouse, rock ptarmigan, bearded vulture…
– the flora: 530 species have been listed including the Saint-Bruno lily, the martagon lily and even the acaule campion…
– flies and biodiversity: hoverflies, a type of fly, are excellent indicators for scientists. Clearing operations in Pormenaz make it possible to assess biodiversity.
