Seco Peak Nature · O Carballiño, Carballiño, Ourense Image of O Carballiño, not of the place itself. At 908 metres it is the greatest height of the concello, on the ridge of the Serra da Madanela and right at the point where the districts of O Carballiño, O Irixo and Piñor meet, between the basins of the Arenteiro and the Avia. Nearby rise the Pico da Peniza and the Pena Cobertoira. Photo: mcxurxo (CC BY 2.0) What to see and do in O Carballiño
