Valley of O Rosal Nature · O Rosal, Baixo Miño, Pontevedra Image of O Rosal, not of the place itself. A valley opening onto the Miño, closed to the west by the Serra da Groba and fertilised by the river's sediments, where terraced vineyards sustain the white wines of the O Rosal subzone within the Rías Baixas designation of origin.
