The La Ría de la Rabía lagoon and the beach of Oyambre make up one of the most wonderful and best preserve spots throughout the coast. It is protected from the sea by a big sandy area. It has a diverse flora, thick woods of alders, hazels and willows. This spot has also an extraordinary population of birds, seventeen species in all, who get shelter there during the winter.
