Iroise National Nature Reserve

Thanks to a national park protected by the authorities, the Iroise Sea has become a refuge for many species of animals. One of the main advantages of the Iroise Sea is its ecological purity. A unique flora and fauna can be observed here, including various species of fish, dolphins and chelonians. It is important in terms of biodiversity as it contains diverse habitats of over 300 species of seaweed, large colonies of sea birds and populations of basking shark (Cetorhinus maximus) and grey seal (Halichoerus grypus).
