This one-way route is easier if you begin at the Castro de Viladonga Archaeological Museum. Take advantage of this opportunity to visit
one of the most important sites in Galicia’s castro culture. From here, the route descends, offering a spectacular panoramic view of the A Terra Chá district. A forest of birch and alder trees gradually covers you as you walk towards Lugar de Monelos.

Here you will find an amazing architectural complex made up of a manor house, Pazo de Fontexón, attached house and mill. The last
two structures have been exquisitely restored. And don’t miss San Xoán de Azúmara Church, just a few metres off the trail.

Continue along the course of the Azúmara River until you come to the former arsenic mine. According to locals, in the 1940s, mining this toxic metal gave an important boost to the local economy. In addition to the mouth of the mine, a long, deep channel which carried water to the mine is still visible, parallel to the trail.

Following the relaxed descent of the river, you will come to the end of the trail, the recreation area at the entrance to the village of Castro de Rei.
