Head down to Port Blanc by foot or bicycle, and you come to an exceptional site where numerous islands run along the horizon, with the Archipel des Sept Iles for backdrop.
Along the coast pass by the Rocher du Voleur ("thief's rock") and come upon the Rocher de la Sentinelle ("sentinel's rock") where two statues keep watch: St Tugdal and Our-Lady-of-the-Sea.
Walk up a few stone steps to reach Notre Dame de Port Blanc, a half-buried chapel classified a historic monument since 1936.
After the nautical centre you can invade the Ile aux Femmes ("women's island"), easily reached at low tide.
You can go bathing or tan on the white sand beach; at low tide go crabbing or collect a few cockles or clams.
This coastline, called the Côte d'Ajoncs, begins at Port Blanc. It has been home to artists and novelists, including Anatole Le Braz who wrote of Breton legends and traditions.
The Anse de Pellinec, the Anse de Gouermel and the Moulin à Marée are also sites not to be missed.
