Two estuaries with hundreds of birds
During fall migration many species stop at both estuaries and delight the discerning bird watcher. The stretch of coast between them provides even more interesting observations. The Ría de Ribadeo, shared with neighbouring Asturias, is a fantastic perpendicular entry to the coast the goes inland until the Eo river estuary, while the Ría de Foz is smaller, albeit more open.
Noteworthy there are the large tracts of intertidal mud flats that feed a large number and variety of birds, as they are home to Zoostera, a sea plant reminiscent of grass which is extraordinarily rich. Between the two estuaries there is a very jagged coastline where beaches and cliffs alternate in continuous succession. The most famous of these beaches is undoubtedly that of As Catedrais. This is a fine section for watching migrating and wintering birds.
