The route starts about 400 metres from the town of O Chao de Pousadoiro, next to the LU-751 road. It runs parallel to the Eo river, between fields and forest.

After a kilometre, the trail ascends and crosses the road. It then passes near the village of San Xurxo de Piquín, where you will find a beautiful church. Following a wide forest path, you will reach the turning leading to the Fervenza de Pena dos Portelos waterfall. Along the access route, you will pass through Fraga da Pena dos Portelos, a native forest with oak and chestnut trees that are centuries old.

The final access to the Survial do Couso stream is equipped with stairs and handrails. Here, the water falls more than fifteen metres down a dark and humid slate ravine, which is covered in ferns and deciduous trees.

To return to the main route, simply go back the way you came. The trail then continues its climb between coniferous and eucalyptus plantations until it reaches the LU-751 road at the height of Chao dos Campos, a place very close to the Miradoiro do Xurxo.
