Réserve naturelle nationale de Chastreix-Sancy

The Chastreix-Sancy reserve occupies a large mountain territory that crosses several municipalities and brings together high peaks, deep valleys, and thick forest zones. The landscape bears the marks of ancient glaciers in its rock formations and slopes, while the different elevations support distinct communities of plants and animals.

Initial protection measures for the area began in 1977, and it later became an official national reserve through formal designation in 2007. This gradual development reflects decades of commitment by conservation-minded people to secure and protect this mountain landscape.

The reserve draws its name from the two prominent peaks that define the landscape, which have long held meaning for the communities living in the surrounding valleys. Visitors often encounter rangers and local naturalists who share their observations and passion for this mountain environment with anyone curious enough to listen.

Multiple marked trails allow visitors to explore the reserve on foot, with some routes connecting to the longer GR 30 hiking path. Sturdy footwear and weather-appropriate clothing are essential since mountain conditions can change rapidly throughout the day.

Alpine marmots and mouflons, wild sheep from Mediterranean regions, have been brought back to live in the reserve after being absent for a long time. This reintroduction work demonstrates how conservation efforts can restore animals to places where they once roamed naturally.
