Urdiñeira Peak Nature · O Riós, Verín, Ourense Image of O Riós, not of the place itself. At 1,148 metres it is the highest point of a concello covered for the most part by oak groves, chestnut woods and pine woods; next comes Castelo da Pena, at 941 metres, above the valleys of the Mente and the Arzoá.
