The Eo river runs alongisde this route for almost half of its journey. The riverbed is characterised by the great biodiversity that surrounds it. The quality of its natural environment means that it is included in the Biosphere Reserve "O Río Eo, Oscos e Terras de Burón".

Starting from the well-kept river beach of O Chao de Pousadoiro, the path runs through riparian forests next to the Eo river and visits the mills distributed along its route. Its natural environment and flat land make this a pleasant route that reaches the recreational area of A Retorta.

After a short stretch of asphalt, the trail leaves the valley floor and begins a zigzagging ascent towards the stony and magnificent viewpoint of Pena Millares, with exceptional views of the Pena Armada and Meira mountain ranges, as well as of the Eo river valley.

Before it ends in Barcia, the path passes through the village of Sadrarín, where examples of traditional architecture can still be seen, particularly in its typical granaries.
