Walking

You will find yourself at the bottom of the ancient lake of Chirens which, after the ice melted around 15 years ago, was filled with sediment and peat to become a marsh. Beautiful views over the ancient glacial valley of the Val d'Ainan.

These marshes today extend over 380 hectares between the foothills of Chartreuse and Lake Paladru.
Wet meadows, reed beds, pastures, cereal fields and afforestation ... It is a mosaic of environments with great floristic diversity. A rich variety of plants flourish on the site such as Orchids and species specific to wetlands such as willows or reeds. The path of the Dragonflies developed by the Department offers the discovery.
