Oriented from south to north and formed by the mouth of the river Mero, takes its name from the parish of the same name, in Culleredo. It is shallow, with silty and sandy bottoms, and in some corners it is covered by patches of marshes where many water birds come to rest at high tide.
And, the beach of Santa Crisitina, where you can discover, on the way to this beach, large plovers, cormorants, egrets or black-footed terns. Watch out for groups of seagulls at low tide to detect a herring. From the beach itself, looking out over the estuary, it is easy to discover in winter common black-necked grebes, loons, moose and sometimes black-necked grebes, as long as the sea is not too rough!
