  • Located in the southwest of Asturias, between the boroughs of Ibias and Cangas del Narcea.

  • Plant life

    Another of the fascinating secrets of Muniellos is its wide variety of mostly edible mushrooms and fungi, with more than four hundred species scattered throughout the forest. Plants make the most of any winter sunshine to release their intensely coloured fruits. Almost four hundred different species, some of which are included in the catalogue of Endangered Species of Flora of Asturias.


    Muniellos Forest constitutes an important reference for animal lovers in Asturias in terms of its wildlife. A plentiful, varied and elusive wildlife that hides in the forest's nooks and crannies, fleeing from the presence of humans. The Cantabrian brown bear is the most representative animal in the reserve, where it finds suitable conditions for its growth and survival. The wolf inhabits the mountainside, with stable breeding areas and the presence of family groups, feeding on other animals that inhabit the area like wild boar and deer. It is possible to see the fur shed by foxes in autumn, the season when the squirrels, jays and capercaillie substitute their spring diet for the abundant fruits that fill the forest: blueberries, blackberries, hazelnuts and acorns.

Truly unspoilt nature in the largest oak forest in Spain, Muniellos Forest Nature Reserve.

It comprises Mount Muniellos and Mount La Viliella (Cangas del Narcea) and Mount Valdebois (Ibias). The largest oak forest in Spain, and one of the best preserved in Europe, is home to truly unspoilt nature, reborn each season with amazing examples of its adaptation to the environment. Ever changing, it is a clear example in all seasons of the natural paradise that is Asturias. Different species of oak with canopies of up to six metres in diameter, beech and birch woods continuously dotted with holly and yew are the perennial autumn kings of Muniellos.

This fantastic forest, brimming with legends and Asturian mythology, sits on a Paleozoic substrate some 500 million years old. Here can be seen ancient glacial cirques and crushed quartzite scree. Testimony to the glacial origin of Muniellos are the small lakes on La Candanosa Peak, four pools of enigmatic beauty, hidden among valleys, trails and peaks. The climb up to these lakes, known as La Peña, Grande, Fonda and La Isla, comprises one of the most interesting trails for hikers.

The River Muniellos or River Tablizas, a tributary of the River Narcea, runs through the forest, collecting the waters of numerous streams that rush down its hillsides. The climate is typically mountainous with high levels of rainfall, around 1,800 litres per square metre, and temperatures of 10ºC at mid-mountain and below 6ºC in the region of the peaks. Snow is common during the cold season, remaining through most of the winter at higher altitudes.

To preserve its exceptional state, visits are restricted to groups of twenty people a day and must be booked in advance on the official website of the Government of the Principality of Asturias:
