Etang de La Hardouinais
Located on the edge of the eponymous forest (privately owned), the Hardouinais pond, an artificial reservoir covering some 50 hectares, was originally created to supply water to the small pond located downstream on the Meu river, which was to provide the water needed to drive the bellows of the Hardouinais blast furnace.
Water sports on the lake in summer.
