In its left bank, at Goães, it has as its tributary the river Mau, who rises in the neighboring parish with the same name and with which it shares a border. Its flow is gentle, which characterizes it as a Ribeiro.
Situated on the slopes of the Oural, Goães is thus abundant in water, which is one of its greatest natural richnesses alongside the greenery and panoramic views of great beauty.
It is crossed by the E.N. 308, that connects to the heart of the municipality, linking with the E.N.201, towards the municipalities of Ponte de Lima (approximately 10 Km), Braga (about 15 Km) and Viana do Castelo ( 20 Km ). Within 1 km is the access to the A3 Motorway, Oporto being roughly 80 km away and the border with Spain another 70 kms.
