Landro River Nature · Viveiro, Mariña Occidental, Lugo The Landro river rises at 800 metres above sea level on the slopes of the Gistral, in the parish of Viveiro belonging to the municipality of Muras, and runs some 37 kilometres in a south-north direction until it flows into the Viveiro ria, between Covas beach and the port of Celeiro, where it forms a small wetland. Along its course, which forms the boundary between the municipalities of Muras and Orol before entering that of Viveiro, it receives numerous tributaries, among them the Besteburiz, Balsadas, Grandal, Boimente and Loureiro rivers. Declared a Special Area of Conservation of the Natura 2000 Network, this short river, which crosses the valle del Naseiro, is home to species such as salmon, common trout and eel, along with notable riverbank vegetation.
