The beginning of this route, on coming to Cachón dam, runs for almost 2 km by a hydraulic canal that was
built in the mid-20th century to divert the river water and produce energy that supplied the tin mines of Sierra
After completing the canal stretch in La Bomba, at the meander of the River Arnoia known as Coto de Seoane,
there is a sharp climb up westwards. We then come back to the river to see the remains of the Chancela Mills
on the other bank from the route. In the village of O Viso we can visit the small chapel of As Angustias before
going up a narrow path between walls and reaching the higher lands of the Sierra del Seixival, and the end of
the route at the Sanctuary of Nosa Señora do Val.
A Baroque building on the ancient Pilgrims’ Road
to Santiago coming from Porto and Celanova. Our
attention is drawn to the remains of the unfinished
Renaissance courtyard, where the cemetery lies. From
the sanctuary we can go back to Escudeiros along a
three-kilometer trail heading eastwards.
