The Ribadeo estuary retains an aspect of estuary, with high margins modeled at its base by the tide and the waves that break vividly in the Quebrantas and Pancha Island. To the west, in a small concavity, the typical fishing port of Rinlo is housed. From Ribadeo to the estuary of Foz, the abrasion platform of San Miguel de Reinante and Barreiros extends, a flat coastline of rich crops lying in the sea in arches of beaches such as the one supported by Promontoiro and Corveira points.
