If you have already visited Marseille, you may have already spotted the Riou archipelago, which is visible from the Marseille coast. Covering 160 hectares, the Riou archipelago consists of four large main islands and many islets, all uninhabited: Riou island (in French, l'Ile de Riou), Jarre island, Jarron island, Calseraigne island, Maïre island and Moyade island. All these islands belong to the Conservatoire du littoral since 1993 and have been part of the Calanques National Park since 2012. The Riou archipelago is the only uninhabited archipelago on the French mainland coast, but it is the only archipelago on the French coast where nature is preserved in its "purest" version. Unlike the Frioul Islands, there is no shuttle bus that can take you to the archipelago: the only way to reach Riou island and the Riou archipelago is hiring a boat in Marseille. During your holidays in Marseille and its surroundings, come and spend a day in the heart of this protected archipelago that is known for its exceptional biodiversity!
Riou island
Riou island, also known as "the island of birds" and which is about 2 kilometres long and 500 metres wide, is the largest and most important island in the Riou archipelago. It is also the only island in the archipelago where it is possible to land, while access to the other islands is forbidden. The island is formed by high cliffs of white limestone in the south part and sandy beaches and pebbles in the north. The island is a true paradise for nature lovers who can discover exceptional fauna and flora: the island hosts more than 320 species, 18 of which are protected. Since the island has been under protection for many years, you may meet many species of birds (the seagull, also named the seagull of Marseille - the shearwater, a rarer species that only reproduces on the island of Riou and on the slope of Ibiza - and hawks) but also the wild rabbit and the ocellated lizard. Once back on board your sailboat or catamaran, go and discover the numerous coves bathed in turquoise waters! If you are looking for a dream mooring, we recommend that you stop at the Anse de Monasterio!
