Retriñón Peak Nature · Sobrescobio, Nalón, Asturias Image of Sobrescobio, not of the place itself. At 1,862 metres it is the greatest height in the municipality and heads the Mermeya range, which drops from its summit down to the Tanes dam. Along that same line come El Moroma, La Frayá, Riegos and La Mezquita. Photo: Jordi Ballesta Castro (CC BY-SA 3.0 es) What to see and do in Sobrescobio
