Turn right past the Casa do Diogo (on your left, rooms available) and through Arão. There is not much to the town.
Soon you will pass over the railway, and into the city limits of Valença. Turn right to follow the road (it is in a poor state for cars but suitable for pilgrims), turning right at the first roundabout and left at the junction shortly after. You are now walking due north towards Spain and directly into Valença.
