Coming into town along the road is OK, but once you get there you will find that the arrows have been removed. Turn left after the church; the camino rejoins the trail in 20m and the country track resumes.
It is pleasant walking along these trails. When you emerge onto the main road, there is a sign on your left indicating Ansião and another on your right indicating Loagoa da Ameixieria.
The center of Ansião is still 1.3km away, turn left to get there, but read carefully the notes about what to do next.
