Onís, hidden in the heart of the Picos de Europa is a destination to discover. It is nature in its purest state, from the valley of the Güeña river to the peaks of the Cornión massif, and it is the millenary culture of its shepherds and Gamonéu cheese.
The Valley and our Villages
Onís is a high altitude municipality. Here the relief only relaxes in the valley of the river Güeña, which runs through the municipality from east to west, receiving its tributaries on its journey to the river Sella.
We are a mountain territory, to the south we are escorted by the great peaks of the western massif of the Picos de Europa and to the north by the Sierra del Hibeu, in the foothills of the Sierra del Cuera.
