Plaiaundi
The Plaiaundi Ecology Park is a 24 -hectare coastal wetland lying where the Bidasoa River meets the sea in the Bay of Biscay. This is in the Basque country of northern Spain, close to the border with France. It is near Irun and Hondarribia in Gipuzkoa, Spain, and Hendaia in France. The confluence of the sea and river have made it one of the most important sites for migratory birds in Europe, with up to 175 species seen visiting the park each year. It is a natural flora and fauna reserve. The park contains three lagoons, two of which are tidal, and a beach.
