La Triguera Nature · Laviana, Nalón, Asturias Image of Laviana, not of the place itself. At 1,291 metres it is one of the main heights in the municipality, in the eastern, limestone half where the greatest altitudes are concentrated. From its ridge you look down on the narrow floodplain where the Nalón reaches its widest, at Pola de Laviana. Photo: Alter.ego (CC BY-SA 3.0) What to see and do in Laviana
