Mountain range of o Suído en Beariz Nature · Beariz, Carballiño, Ourense Image of Beariz, not of the place itself. The serra do Suído forms the border between Pontevedra and Ourense: on the Ourense side it extends across the municipalities of Avión and Beariz, where the river Avia rises, and on the Pontevedra side across A Lama, Fornelos de Montes and Covelo. Metamorphic rocks predominate, especially Hercynian granite, with gentle forms and flat areas on the peaks; in Beariz it reaches its highest points at Marcofán, at 940 metres. Its acidic, damp soils also give rise to the rivers Tea, Oitavén and Verdugo flowing westward, which descend in rapids and waterfalls. Halfway up the slopes there survive woods of carballos, cerquiños, bidueiros and acebos; higher up there are pastures, scrubland and gorse (toxo), and the dry-stone chozos that shepherds used for centuries to shelter livestock in summer still survive. It is one of the rainiest areas in Galicia. Photo: Kandedo (CC BY-SA 4.0) What to see and do in Beariz
