The Ría del Eo, also known as the Ribadeo estuary, is a 10-kilometre-long coastal inlet that serves as the natural border between Asturias and Galicia.
Part of the Río Eo, Oscos y Terras de Burón Biosphere Reserve, this estuary is one of the most important wetlands in Spain.
Surrounded by rocky cliffs reminiscent of the Norwegian fjords, it is a unique destination for nature lovers and birdwatchers.
To feel like we are walking among giants and feel the size of an ant, there is no need to travel to Norway and sail through its fjords. Scattered across Spanish territory, we can find equally impressive enclaves, places whose dimensions remind us how small we are in the face of the immensity of the world. One of these fascinating places extends to the north of the peninsula, facing the Cantabrian Sea, and serves as a natural border between Galicia and Asturias. The Ría del Eo stretches for 10 kilometres inland and is part of the Río Eo, Oscos y Terras de Burón Biosphere Reserve, one of the 7 Biosphere Reserves in Asturias.

A NORWEGIAN-STYLE ENCLAVE IN THE CANTABRIAN
Between the towns of Ribadeo in Galicia and Castropol in Asturias, the Ría del Eo is one of the most spectacular natural corners of the northern Iberian Peninsula. Extending proudly before the wild waters of the Cantabrian Sea, it presents a deep breach where the river and sea waters meet and separate Asturias from Galicia. This scar in the terrain extends for approximately 16 kilometres. What the two sections of the estuary have in common is that, along its entire route, it is bordered by rocky cliffs and mountain slopes, reminiscent of the imposing fjords of Norway. Here, nature reaches its maximum splendour, mixing the strength of the Eo river waters, the river valleys created over millions of years, and the magnificent beaches scattered along its estuary.
