The Feitos river has its source in the Monte de S. Gonçalo (the highest elevation in the municipality of Barcelos). The steep descent of the rock formations and the collision of water over time have formed waterfalls and lagoons that are true strongholds of nature. The Enxate lagoons located in the parish of Vila Cova are an example of a truly natural space, carved into a cliff at the foot of the hills of S. Gonçalo and S. Mamede.
