No one better than the portuguese author Miguel Torga to describe the unique beauty of this region:

"The sublimated Doiro .The prodigy of a landscape that ceases to be, due to its immeasurability. It is not a panorama that the eyes behold: it's an excess of nature. Terraces that are the pace of titan men climbing the slopes, volumes, colors and modulations that no sculptor, painter or musician can translate; dilated horizons beyond the plausible thresholds of vision".
