The Pink Granite Coast of Côtes-d"Armor in Brittany, France, is a unique site in the world. It extends over ten kilometres through the municipalities of Trébeurden, Trégastel and Perros-Guirec. Formed almost 300 million years ago, this granite rock slowly cooled from a magma chamber, enriched by external minerals. Unlike other similar coasts, such as in Corsica or China, this one is characterised by blocks of rock stacked or forming structures with soft, rounded angles, shaped by erosion.
