Passy National Nature Reserve

The reserve spreads across 1,717 hectares between the Aiguilles Rouges and Mont Blanc mountain ranges, featuring calcareous cliffs and diverse geological formations.

Established in December 1980, this protected area connects the Sixt-Passy National Nature Reserve with the Aiguilles Rouges National Nature Reserve in Haute-Savoie.

Local shepherds maintain traditional Alpine farming practices by grazing their cattle and sheep in the high-altitude pastures during summer months.

Visitors can access multiple marked trails throughout the reserve, offering opportunities for wildlife observation, hiking, and nature photography in different difficulty levels.

The vertical walls of Fiz cliffs rise 600 meters high, displaying 90 million years of geological history between ancient oceans and Alpine formation.
