The first ecological body of water open to swimming in France, in a breathtaking panorama, facing Mont-Blanc... Rather than chlorinated swimming pool water, natural water taken from the drinking water network is warmed by the sun's rays up to 26°C.

More than 10 aquatic plants ensure impeccable water quality in the 000m² of swimming areas. Heated naturally by the sun's rays, the water temperature varies between 1900°C and 19°C, thanks to a tarpaulin stretched at the bottom of the swimming pool, with gently sloping access ideal for children. The lake is located in the center of the village in an alpine landscape preserved from any “concrete” architecture. The lake is bordered by a wooden solarium and a grassy beach and a restaurant bar.

To allow the plants to carry out their work in good conditions and have optimum water quality, the number of daily entries to the water body is limited to 800. Reservations strongly recommended.
