The first ecological swimming lake in France, in a breathtaking panorama, facing Mont Blanc... Enjoy water free of any chemicals to refresh yourself during your mountain holidays in Haute-Savoie!
Over 10,000 aquatic plants ensure impeccable water quality in the 2,900 m³ swimming area. To allow the plants to thrive and maintain optimal water quality, the number of swimmers allowed is limited per day. Reservations are strongly recommended during peak season. The biotope lake is not heated. The water temperature depends on the weather and generally varies between 18 and 25 degrees Celsius. A gently sloping access point makes it ideal for children.
