The first section of the route is shared with PR-G 81 and 82. It begins in the car park at the crossroads between the new and old highways from A Trabada to As Rodrigas. At this point, there is a panel with a map of the two routes.

At the entrance to the fraga (forest), there is a refuge hut with explanations about the surrounding plant life.

The route climbs up alongside the Vilapercide stream to its source. Crossing from bank to bank by wooden footbridges, we can appreciate the typical dark, humid riverside forest. Identification plaques occasionally help to recognize the different tree species.

In As Liñeiras, the two paths separate and the PR-G 81 enters into the upper part of the autochthonous forest where Galician carballos (oak trees) are most common. The way down to the starting point is easy going.
