Iroise Sea Natural Marine Park Adventures

Established in 2007, the Iroise Sea Natural Marine Park covers approximately 3,550 square kilometers of sea and coastal habitats along the western tip of Brittany, including the islands of Ouessant, Molène, and Sein. It stretches from the rugged coastline out into the Atlantic, where the meeting of the English Channel and the Bay of Biscay generates some of the strongest marine currents and waves in Europe, shaping a unique and dynamic ecosystem. This area is a hotspot for biodiversity, supporting numerous species of seabirds, marine mammals such as seals and dolphins, and a vast array of fish and invertebrates. The marine park balances conservation with human use, regulating fishing to protect sensitive habitats while promoting sustainable tourism. Visitors are drawn to sailing, diving, kayaking, and birdwatching opportunities, all enhanced by the park’s natural beauty and cultural significance, including historic lighthouses and traditional fishing villages. The marine park also acts as a research hub, monitoring ocean health and contributing valuable scientific data. Its combination of rich marine life, dramatic seascapes, and strong local maritime traditions offers a compelling destination for nature lovers and outdoor adventurers alike.
