A surprising space in the middle of the forest of Fontainebleau, the sands of Cul de Chien originated 30 million years ago. At the time there was a warm ocean here that deposited quartz in its depths. Time doing its work, it disintegrated into sand, forming this beach in the middle of the woods. In addition to the surprising environment, the sands of Cul de Chien represent a mythical place in the history of climbing in Fontainebleau.
