In Sainte-Agathe-des-Monts, this lake is the pride of joy of locals, with its more than 13km of public and private beaches. This lovely expanse of lake area, with natural sources and forming an approximate "H" shape can reach depths of 25m. Admire it from Parc Lagny, at the foot of the main road, or take a boat trip on the waters and get a glimpse of the fine houses bordering it: they have welcomed the likes of Jackie Kennedy, Queen Elizabeth II and multi-millionaire Lorne McGibbon.
