The path is linear and runs from A Ponte to Sestil Alto. The route begins in the plaza of the church of Santa María Madalena. You should not leave A Ponte without visiting the ZEC Pena Trevinca Visitor Centre or the Casa dos Vaqueiros, which has pre-Roman carvings in the stone of its exterior walls.

After crossing the Pontón de Pena Pausa, the route continues along a path between walls, towards the Pontón das Olgas. Before arriving there, the route ascends towards the Meladas river valley where it will briefly share its route with PR-G 198.1. Once separated from this variant and after crossing a wooden footbridge over the Meladas river, the ascent begins on the crest of Sestil Alto. From above, you can enjoy magnificent views over the glacial valley of the Xares River.

The route ends between the summit of Sestil Alto and A Valigota, where it connects to the PR-G 198. From there, you can access the summit of Pena Trevinca in just 1.8 km. You can return the way you came or via any of the connected routes.
