The Ribadeo estuary forms a natural link between Galician territory and the neighbouring lands of Asturias on the opposite bank. On this deep estuary, formed by the river Eo, the main town is Ribadeo.

The town's stately appearance can be seen from the nearby summit of mount Santa Cruz, where a popular pilgrimage is held every first Sunday in August and which has been declared to be of tourist interest because it is a celebration of traditional local cuisine and music.

The Marquis of Sargadelos was the modern promoter of this city whose most outstanding building is the modernist Galician country house of the Moreno brothers. From the port of Porcillán, which is of Roman origin, it is a pleasant walk to the lighthouse of Pancha island, situated on the mouth of the estuary, passing the ruins of the castle of San Damián. On your return, there is nothing more gratifying than to delight at the seafood taken straight from the estuary, such as cockles, clams and oysters, which, along with salmon, trout and eels from the Eo, are the star ingredients of the local cuisine. Not forgetting the delicious sweets made by the nuns at the convent of Santa Clara.

It is also a good idea to spare some time for As Catedrais, one of the most beautiful stretches of sand on the Galician coastline. Its rocks, which form natural arches resembling a cathedral, create a magical landscape which changes with the tides, the high point of a walk facing the open sea.
