It is located on the walkway that runs along the left bank of the Cávado river, from the D. Luís Filipe bridge to very close to the river mouth.
Inserted in the North Coast Natural Park, this place in the Cávado estuary is characterized by the uniqueness of its reeds and Atlantic salty meadows. Its ecological relevance is based on the nutrient loads brought into the estuarine waters that constantly flood it and the high biological productivity indexes of its marshes and mudflats uncovered at low tide, so favorable for the occurrence of avifauna.
Located in an important migratory corridor for birds, this wetland is, therefore, a habitual stopping place or wintering destination for many species that find here a mild climate and a diversity of wide natural habitats that guarantee their sustenance and the necessary conditions for rest and protection. Here proliferate mainly waterfowl species, such as herons, ducks and cormorants, or waders such as sandpipers and ruddy turnstones that occupy this margin.
