After passing the Quinta da Boa Viagem, take the first road on your right. The next arrow is low on the curb and has you turn left and you will soon find yourself on a country road flanked by forests on both sides. Were the forest ends the road you have been following takes a sharp bend to the left, but the camino turns to the right to follow a narrow track.
When the track emerges it will turn right along the Rua do Louvado and then keep to your left to walk along the cobbled path with stone walls on either side. When the road opens up again there are several roads to choose from, and the one you want is the second from the right. It will take you uphill slowly but steadily until it reaches a fork in the road, at which point the camino takes a turn to the left and downhill, again between two walls.
A short distance on it take the first road on the right. The arrows in these parts are well defined and the camino will eventually emerge in Carreço. A bridge over the railway will appear on your left and it marks your arrival.
