A Mariña is one of the best-defined regions of Galicia. It encompasses the entire coast of Lugo between the Ribadeo estuary and the Barqueiro estuary, as well as several inland municipalities in the valleys of the Landro, Ouro, Masma, and Eo rivers. The eastern and central coastline is characterized by the so-called “Cantabrian Rasa”, a fairly straight coast where the Ribadeo and Foz estuaries open up. From San Cibrao, in the municipality of Xove, the coast becomes more rugged, with hidden beaches and higher cliffs, where the Viveiro and Barqueiro estuaries open up at the border with the province of Lugo.
Inland, which is less populated, many of the mountains exceed 800 meters in the Xistral, Cadramón, Lourenzá, and Pousadoiro mountain ranges. Highlands where pastures are abundant and where cattle are often seen roaming freely. In fact, at the beginning of summer, several “curros” take place in this region, a festival held to gather or bring down free-roaming cattle from the mountains, especially horses and cows, to wooden or stone enclosures where they are gathered to be cleaned and marked.
This mix of sea, valleys, and mountains makes the region home to natural areas of great interest, with various levels of protection or designation: two Biosphere Reserves (Terras do Miño and Río Eo, Oscos, and Terras de Burón), two natural monuments (Catedrais beach and the souto of da Retorta), and those that are part of the Natura 2000 Network, both coastal and inland: Landro river, Monte Maior or Ouro river, the Foz-Masma estuary, the Eo river or the Carballido forest.
