The great Biosphere Reserve of the Cantabrian mountain range extends from Os Ancares to the Picos de
Europa. The Lugo Os Ancares form its western border, full of diversity, magical by nature.
The humans who were able to settle in this difficult territory also moulded it and conserved its patrimony.
Even now the visitor can open the doors of some pallozas. Nestling below the straw roof which gives them
their name, these strange dwellings give us an insight into life in ancient times.
The mountain is coloured in infinite tones of green at the different altitudes. Os Ancares is surprising, not
for high altitudes but because of the steep drops. From the boxed-in valleys standing at less than 300
metres they rise to almost 2,000 metres in just a few kilometres. The rivers on the Galician slope are the
Navia, Rao and Ser; and the main peaks are Mustallar and Tres Bispos.
