This short route passes through monte Castrove which is located between the municipalities of Meis and Poio. There are two important medieval monasteries: the Benedictine monastery of San Xoán de Poio and the Cistercian monastery of Santa María de Armenteira. 

Leaving from the vicinity of Pereiro de Abaixo, we take a path that enters the forest and which will take us first to regato de Fentoso, where we cross a recently built wooden bridge to continue upstream along the left bank of the river. We will cross a couple more wooden footbridges before reaching the most outstanding point of this route, the A Freixa Alta Waterfall, which ends this route with a waterfall of approximately 10 m.
