Circular path that begins and ends in O Campo da Feira de Bembibre. From this point, the route runs along the right-hand bank of the Dubra river to Insua de Santa Mariña de San Román, from which it returns to the beginning. On its way, there is a turn towards the Rego do Portonabo riverbed, a tributary of the Dubra, which forms a waterfall in two sections, adding about 10 meters of uneven passage.

The tour alternates fishing paths and trails, as well as agricultural farmland and meadows with forest areas. Among the latter, the route goes through repopulation areas and other native areas with holly, cork oak, laurel, oak and chestnut trees.

About two kilometres from the start, you will find the isolated chapel of San Xoán Bautista, a surprising find in this uninhabited area within the mountains of the San Martiño Coucieiro parish. Built in the 17th century, it is believed to be standing on the remains of a primitive mediaeval temple. Once abandoned and in ruins, it was restored in the first decade of the 21st century to recover the numerous pilgrimage routes around it. Nearby is the source of Augas Virxes, considered to be miracle waters.
