Lake Annecy, in the Haute-Savoie region of France, is fed by mountain springs and known for its clean water. At its north end, Annecy has a medieval old town with canals and bridges. The 13th-century Château de Menthon-Saint-Bernard perches above the lakeside village of Menthon-Saint-Bernard. The town of Saint-Jorioz has a popular beach. There are trails around the shore and pleasure boats dot the lake in summer.
