A Site of Spanish Geological Interest of International Relevance (also defined as Geosite), the granite of O Pindo stands in the way of the last kilometres of the Xallas River, which in its course, to overcome the difference in height of 155 metres, traces a profile that ends in a waterfall of 40 metres. On the bed of this spectacular waterfall, large pias and kettles were carved. The Xallas flows through a valley at an altitude of 280-320 metres, on relatively soft schists and, at about 200 metres from the sea,
Its mouth is still 120 meters high, “jumping” directly over the sea. This spectacular phenomenon seems to be unique not only in Spain but in all of Europe.
