This pathway is remarkable for the beauty of the banks of the River Sor. It starts after passing the town of O Morgallón, at the crossroads of a large esplanade. It continues along a local highway until the bridge that crosses the river at Monte de Ínsua de Baixo. From here, it heads up-river to Ponte Ulló.

A now-abandoned electric power station, an old seat-bridge which, thanks to a pulley, crossed the river, and a beautiful mill, are some of the things to be seen along the route.

Ponte Ulló Dam is a major fish reserve. After crossing the isthmus that separates the two sections of river, we take the path back alongside the course of the water hemmed in between vertical banks. When we get back to Monte Ínsua and after crossing the bridge, a pathway on the right bank of the river leads to another "chair bridge".
