Geography
editSituation
editWith a surface area of 5.45 km2 (2.10 sq mi) it is one of the largest natural lakes of France.[3][4] It is the fourth-largest natural lake in the Auvergne-Rhône-Alpes region, after Lake Geneva (although partly in Switzerland), Lake Annecy and the Lac du Bourget. It has a maximum depth of 71 metres (233 ft). It is part of the Avant-Pays savoyard, formerly known as the Petit-Bugey.
It is noted for its blue-green colour and seven hot water springs. The communities of Aiguebelette-le-Lac, Lépin-le-Lac, Saint-Alban-de-Montbel, Novalaise and Nances border the lake, while the Chaîne de l'Épine ridge lies to the east with its high point at Mont Grêle (1,425 metres or 4,675 ft), south-southeast of the lake.
At the southern end there are two islands, La Petite Île and La Grande Île, the latter of which has a chapel, the Chapelle Saint-Vincent, administratively part of the commune of Lépin-le-Lac.
Transport
editThe lake is served by the railway line from Saint-André-le-Gaz to Chambéry; the section between Lépin-le-Lac-La Bauche station (southwest) and Aiguebelette-le-Lac station (southeast) offers panoramic views on the lake.
The A43 autoroute is north of the lake.

Recreation
editThe Chaîne de l'Épine ridge is crossed by hiking trails; paragliders launch from there during the summer.
Motorboats are not allowed on the lake to preserve the silence and wildlife along the lake. There are noted views of the lake from the church at Saint-Alban-de-Montbel and the mountain ridges.
