Quite nice here 😉 At least for a little picnic and break, as the coastal path is quite challenging.

Ruins of a historic mill that was fed by the Ru de Matignon. The mill is not only a popular hiking destination, but can also be easily incorporated into a mountain bike tour. The trails along the Ru de Matignon or from La Forge are absolutely worthwhile.

At high tide it is the end of the headland, at low tide you can walk further to the next island.

This river mill owes its name to the fact that for a long time it was the closest mill to the sea. In the Middle Ages, the Lord of Matignon had a "grain mill" built on this site. The population was obliged to have their grain milled there and to pay a fee to the miller. It was supplied with water by a reservoir, now filled, located on a stream that flows into the bay of La Fresnaye at the place called Port-au-Moulin. Upstream, another river mill had been built, the Clos mill, at the place called La Vallée. Downstream, a tidal mill with a dike and seawater dam, the Roche Noire mill, was built in 1869. A windmill, the La Vigne mill, located in Bellevue, took over during droughts. There were therefore four mills in this area. During the Revolution, the Mer mill was auctioned off as national property. Around 1850, René-Marie Durand, a miller, became the owner of this mill. His eldest son had the Roche Noire mill built; his sons and grandchildren also became millers. The mills ceased operations around 1925.
