Around fifteen kilometres off the south coast of Finistère, the Glénan archipelago unfurls its islands, islets and reefs in the heart of a lagoon with a tropical feel. Crystal-clear water, white sand, dazzling light… Made up of nine main islets and a multitude of reefs, the archipelago stretches around a central lagoon sheltered from the winds. The most emblematic islands include :
Saint-Nicolas: The tourist heart of the archipelago, this is where you disembark for a stroll along the beaches, following the signposted paths.
Penfret: Formerly inhabited, it now houses a nautical centre and semaphore.
Drénec: Wild and peaceful, a popular spot for nature lovers.
Bananec, Guiriden, Cigogne, Loch: So many islands with evocative names, each with its own character.
The archipelago is classified as a Natura 2000 area, reflecting its great ecological wealth. It is home to many species of plants and animals, both on land and at sea.
And if you’re lucky, you may even catch a glimpse of grey seals, dolphins and even the basking shark, a peaceful giant threatened with extinction at national level. Discover our other protected natural areas!
Megalithic remains attest to the presence of man since the Neolithic period. For centuries, the trading activity of the ports in South Finistère attracted a great deal of interest. The Glénans were the ideal hideout for pirates from England and the Netherlands. During the 19th century, fishing boomed, with the construction of fish dryers and shellfish tanks. The construction of a soda factory on Le Loc’h at the end of the 19th century marked the industrial history of the Glénan. The seaweed collected nearby was burnt to make soda ash, which was then sold to industries on the mainland.
A paradise… with no permanent inhabitants.
Today, no-one lives there, but many people do come… And yet many human activities take place there. Every year since 1947, the Glénans sailing school has been a veritable institution, welcoming many trainees to the islands. For sea bass, pollack and mackerel fishermen, the Glénans is a fantastic playground.
The archipelago is home to one of Europe’s largest maerl beds.
Crystal-clear water, white sand, dazzling light… This picture-postcard setting, which has earned the site the appellation “Breton Caribbean”, owes its beauty to the clear granite seabed and the presence of maerl, an extremely calcareous red algae that contributes to the purity of the waters and gives the fouesnantais sand its “ultra bright” whiteness as it decomposes.
