Not to be missed: The main access route to Os Ancares starts from the town of Becerreá and goes to Liber, where there are three possible
routes by secondary and local roads. Towards the north, following the course of the river Navia, we reach A Proba, the
capital of the municipality of Navia of Suarna. The town has an extensive cultural and artistic heritage represented by the
picturesque design of the medieval castle and the one-arched Roman bridge built in slate. But outstanding also are the
twenty five castros which still exist, like those of Cantón and Cabanela, united by a 300 metre corridor; four burial mounds;
the high settlements that were old summer residences in high areas like Bismor or Tesón; "cortíns" or "alvarizas" around
beehives to protect them from bears and pallozas (ancient circular dwellings).
The second route going south from Liber takes us to Degrada, either via the municipal capital of Cervantes in San Román,
or via Doiras and its castle, impregnable because of the strength of its stone construction and its location on a hill above
the river, and of difficult access. The privately owned castle is also famous in literature because of the legend of the womanhind,
daughter of a poor man who was bewitched by a Moor (a recurring character in Galician popular mythology) and
The youth hostel of OS Ancares and the Interpretation Centre are in Degrada. From here starts the route on foot, of
medium-high difficulty, which leads to the Campa de Tres Bispos (1,795 m). However, the most used route continues up
the winding road to the village of O Piornedo. A visit to the pallozas is a must. These are ancient circular dwellings which
were inhabited until the 20th century. Some are open to the public as museums of the past, well-guarded in the family
memory of their owners.
