Take a moment to admire this magnificent stretch of water. At 33 hectares, it is the third largest lake in the department after Geneva and Annecy. Maximum depth : 19m. Length: 1320m. Width: 235 m .

Fishing : as with all other mountain lakes, fishing commences on the first Saturday in April. Numerous species live in the lake, including Omble Chevalier, Truite Fario or Arc-en-Ciel and Vairon.

Activities : in winter, the lake is frozen in a coat of ice, in places a metre thick. Ice-diving is one of the attractions; you can also practise cross-country skiing on prepared tracks, for which there is no charge.
