Waterfall of o Cenza Nature · Vilariño de Conso, Viana, Ourense Image of Vilariño de Conso, not of the place itself. The fervenza do Cenza is a natural waterfall on the río Cenza, a tributary of the Bibei, as it passes through the parish of Castiñeira, in the concello of Vilariño de Conso. A stepped waterfall of nearly a hundred metres of drop, it is considered the highest indirect fall in all of Galicia; a wooden walkway leads to a viewpoint at its head. Its flow has been affected by a quarry located nearby. Photo: Estevoaei (CC BY-SA 4.0) What to see and do in Vilariño de Conso
