We begin the route in San Martín de Oscos where we can see the parish church, with a Latin cross plan, large porticoed space and inscription of 1828. To the right of the facade we observe one of the most characteristic hórreos of the Oscos with a mixed roof (slate and straw), which corresponds to the primitive models. In front of the church we have the mansion of the Guzmanes, an old manor house of the XVIII century, which preserves in the portico of its main entrance a coat of arms carved in stone. We cross the bridge that crosses the San Martín river to begin the ascent to Mount Marón, entering a small forest of birch and oak trees, which make our walk even more pleasant.
Already at the top of the summit (897 m) we can see most of the council of San Martin, as well as other neighboring: Santa Eulalia, Illano, Grandas de Salime, Pesoz and A Fonsagrada. After delighting ourselves with this view of distant horizons we descend through a pine forest, meeting the access road to Ascuita. After 1.25 km we reach this small village, once very busy because it was on the road between San Martín and Santa Eulalia. We return to the main road and head towards Vilarín de Trasmonte, passing by the hermitage of Santa Engracia. Currently this route is connected with a section of the Las Minas route, exactly with the one that leads to the Carmina Mine. At a given moment, the signage will warn the hiker of this circumstance. The return to San Martín will be by road.
This route starts at the Nature Interpretation Center, in the center of Santa Eulalia de Oscos.
The route is made up of two circular sections starting and ending in the center of Villanueva. The longer one, about 12 km, coincides in part with the forest route.
The route begins in the upper part of the village of Bres through a wide dirt road that leads to the Guxo mill, in excellent condition and also has in its vicinity a mini power plant.
Esta ruta circular recorre buena parte del valle del río Cabreira, combinando caminos de montaña en la ida y de fondo de valle en la vuelta. Se inicia junto al hotel La Rectoral, tomando el camino que asciende entre el arbolado hacia la Sierra de Eiroá. Sin llegar a alcanzar su cumbre nos desviamos hacia el pueblo de Piñeiro, para llegar a él en suave descenso y disfrutar de su arquitectura tradicional y cabazos alzados al cielo.
The itinerary begins next to the chapel of Salgueiras, located on the AS-27 road, 6 kilometers from Villanueva. Throughout the tour we must observe the environment around us: the houses, their attached buildings, orchards, meadows, farm implements, forests, to understand the way of life of the locals.
Its fourteen kilometers allow us to enjoy the water and its use for centuries in the rural environment. From the lower part of Taramundi we take a road that leads us to Mazonovo, where we can visit the Museum of Mills.
