Aiguamolls de l'Empordà Natural Park Nature · Castelló d'Empúries, Alt Empordà, Girona The second most important wetland in Catalonia, with ponds, lagoons and fields where more than 300 bird species winter, nest or stop over. The park covers an area of approximately 4,722.7 hectares, of which about 824 are integral nature reserve, and is spread across several municipalities of the Alt Empordà, headed by Castelló d'Empúries, which holds 57.4% of the protected area. It was declared a natural site in 1983 and reclassified as a natural park in 1985; part of the river Fluvià, including the island of Caramany, is a partial reserve for the otter. More than 80% of the land is privately owned, and between its two sectors lies Empuriabrava, Europe's largest residential marina, with 30 km of navigable canals.
