A quarter of an hour from Chambéry on the motorway, Lac d’Aiguebelette lies at the foot of the Épine mountain. It is a lake of glacial origin, known for its calm water: boats with combustion engines are banned, and rowers from all over the world come to train on its marked-out courses.
Unusually, the lake is private. It belongs to EDF (the French electricity company) and to a family, and the Communauté de communes du Lac d’Aiguebelette (CCLA, the local group of municipalities) manages it for the public. Almost the whole lake is a regional nature reserve. You swim from equipped beaches, which charge an entry fee in summer, and taking out your own boat requires a boating permit.
