Sheltered from the ocean by the Cíes islands, Vigo's estuary opens to the north at cape Home and to the south at cape Silleiro. This is an estuary of treasures, because here, in the marvellous inlet of San Simón, there are dozens of sunken galleons loaded with gold form the Americas. Also, the estuary is home to some of Galicia's best beaches: Barra and Nerga in Cangas, Samil and O Vao in Vigo, Playa América in Nigrán... And the one that by many is considered to be the best beach in the world: the Rodas beach in the Cíes islands.
