Betanzos-Mandeo

Betanzos-Mandeo is a protected natural area in Galicia, Spain, covering the valleys of the Mandeo and Mendo rivers across several municipalities in the province of A Coruña, including Paderne. Designated as a Special Zone of Conservation (ZEC) under the Natura 2000 network, it safeguards one of the best-preserved stretches of riparian forest and wetland in the Rías Altas region.

What defines the Betanzos-Mandeo area?

At its core are the Mandeo and Mendo rivers, which cut through narrow valleys before opening into wetlands near the mouth of the Ría de Betanzos. Along their banks, native riparian forests of alder, willow and ash have survived largely intact, typical of the Atlantic and Cantabrian coast of the Iberian Peninsula. These gallery forests, together with the marsh vegetation found downstream, are what give the area its ecological significance.

Why is this river system so ecologically important?

The Mandeo is known for its clean waters and rich biodiversity. Species living in the river include Atlantic salmon, brown trout, and lamprey — a species considered endangered and highly sensitive to water quality and free-flowing river conditions. Their presence makes the Mandeo valley one of the more important ecological corridors in northwestern Spain, linking inland mountain areas with the Atlantic coast.

How does Betanzos-Mandeo fit into the wider conservation landscape?

The area is not an isolated reserve. In May 2013, UNESCO incorporated it into a much larger territory recognized as the "As Mariñas Coruñesas e Terras do Mandeo" Biosphere Reserve, spanning over 116,000 hectares across numerous municipalities in the A Coruña province. The Special Zone of Conservation itself covers around 1,020 hectares, stretching across the municipalities of Aranga, Bergondo, Betanzos, Coirós, Irixoa, Miño, Paderne and Oza-Cesuras.

What should visitors know before exploring it?

The area is popular with hikers and nature enthusiasts, with trails running alongside the rivers that allow close-up views of the riparian forest without disturbing the most sensitive habitats. Its proximity to the historic town of Betanzos, with its medieval old town and the well-known Ría de Betanzos, makes it easy to combine a visit here with cultural sightseeing in the region.
