O Rego dos Muíños or of Roncadoiro is the reason why this route is worth it. They are 3 kilometers along which we can listen not only to the sea sound but also to the river noise, a stream with small waterfalls and amazing spots where we can stop and enjoy.
Along the route, we can see the remains of several windmills that are in its riverbank. 24 buildings which show us how important this river was for the inhabitants of Canduas and Borneiro.
When getting to Borneiro, we have to go across the road and we can see the route to the Castro A Cibda.
