Located to the south-east of the Bois de Vincennes, Lac de Gravelle is the smallest of the four lakes in the area. Its area is around one hectare. Formerly supplied by the Marne, today the water is brought back from the Seine thanks to a hydraulic system provided by the pumping plant of the Austerlitz bridge. This preserved natural site is in fact completely artificial. But no less charming!
