Passy National Nature Reserve

Local nameRéserve naturelle de Sixt-Passy

The Passy National Nature Reserve is a nature reserve located on the face of the Aiguilles Rouges and Mont Blanc mountain ranges, in the middle of the Arve valley, in the Haute-Savoie metropolitan department of France.

The 1,717 hectares have been protected since 1980; the reserve assures a continuous link of protected areas between the Sixt-Passy National Nature Reserve and the Aiguilles Rouges National Nature Reserve.

The natural history of the reserve mirrors that of the surrounding mountains. The young rock cliffs of the Fiz mountain range dominate the former Pormenaz mountain range. The tectonic activity of the Alps continues to bring the Fiz rock cliffs closer to the silicious rocks of the Pormenaz.
