This semi-circular trail must be combined with the PR-G 139 in order to return to the starting point, for a total distance of 14.3 km.

From Lugar de Vilardíaz, the trail descends along the Rodil River valley. The path offers fabulous views, skirting the mountain to Beltrán Bridge, an age-old walkway connecting Vilarxubín and Vilardíaz which has been refurbished to allow hikers to cross. In the deepest part of the valley, chestnut trees provide welcome shade, making the climb up to the village of Vilarxubín more pleasant. In this charming spot, you will find an “hórreo” (raised granary), a common sight in this area.

When you re-enter the forest, you will see a number of “corripas”, small circular or square stone structures used to store and organize chestnuts, a product which was a staple of the local economy and diet.

As you continue along the trail, you will pass very close to Lugar de Vilarín do Castelo and then head back down to the river. Before the river, you can make a short trek off the trail to visit the “seimeira” (waterfall) at Parada. Continuing along the main route, you will come to Castro do Castelo, a pre-Roman fortified settlement situated on an unassailable spot between two rivers.
