An island on the coast of Trébeurden, only accessible at low tide (take care!). The northern part is formed by the "granite rose" (pink granit) of Ploumanac'h, and the southern part by sedimentary rocks of unknown age. These are varves, with a well developed layer structure. Near the contact, the felsic layers of the varves underwent contact metamorphosis, resulting in the forming of cordierite, andalousite and sillimanite.
