Trail of el Oro de Ibias Activity · Ibias, Narcea, Asturias Image of Ibias, not of the place itself. A trail waymarked as the PR-AS 306 which sets out from San Antolín and takes in the channels, cuttings and spoil heaps of the Roman gold mines of the Ibias valley, passing through hamlets such as Cecos and Villamayor among vineyards and heaths.
