Vigie at the tip of the island Maïre in the Riou archipelago, Calanques National Park in Marseille. The two islets of the Pharillons are a high place for diving. It is a rare image because its angle of view is particular. Indeed, the photograph was taken from the island itself, on its south face, at the end of a path that has not been used for a long time because today, landing is prohibited on the island, in order to preserve the local flora and fauna. I had the chance to accompany the teams of the Calanques sur Maïre national park during several scientific follow-ups. Here is a special moment, because a mass is approaching the lookout: it is the mist that comes from the sea and which will soon immerse the island in a whitish and opaque mystery.
