This Natural Park and Biosphere Reserve represents one of the great forest treasures of the Cantabrian Mountains. Its valleys and mountains are covered by extensive beech and oak forests, including the Muniellos oak forest—considered one of the best-preserved in Europe—and the Monasterio de Hermo beech forest, the largest in Asturias. The geological formations, with some of the oldest rocks on the peninsula, give the landscape a unique character. The Park is located in a section of the mountain range dominated by siliceous rocks, giving rise to ridges with blunt profiles and quartzite outcrops, where large scree and dark rock scree are formed, adding a rugged and spectacular character to the surroundings.
It is a key area for the conservation of the brown bear and the Cantabrian capercaillie, as well as home to a remarkable diversity of flora and fauna, with endemic species of particular interest such as the long-tailed salamander and the Seoane viper. The area favors a diversity of habitats, and thus, while Atlantic flora predominates in Fuentes del Narcea, certain Mediterranean influences can already be seen in Degaña and Ibias. Given the predominance of forests, it is an ideal space for forest birdwatchers, with species such as the black woodpecker, which is relatively abundant and easy to spot, and the common bullfinch. On walks through the beech and oak groves, it is not difficult to find traces of roe deer, wild boar, and even bears and wolves. Furthermore, its biodiversity also includes a rich community of insects and invertebrates, including the impressive stag beetle, visible in June and July, and the delicate Rosalia alpina, a cerambycid beetle with beautiful blue hues. Interpreted trails, wildlife observation, and autumn landscape photography offer authentic experiences in close contact with a well-preserved environment.
Added to this is a rich rural culture, with isolated villages, folk architecture, and traditional crafts such as woodworking (the Cunqueira tradition), still alive in the area. Among the most characteristic elements of this architecture are the hórreos (granaries) with stone pegoyos (feet), oak plank structures, and slate roofs, reflecting the adaptation to the environment and the construction wisdom of past generations. An ideal place to reconnect with nature in its purest and most peaceful form.
The best times to visit the Fuentes del Narcea, Degaña, and Ibias Natural Park and Biosphere Reserve are from spring to autumn, when this area displays all its scenic and biological splendor. In spring, roadsides, meadows, and hillsides are filled with color with the flowering of wild plants, the heaths bloom, and the trees begin to shed their leaves, while amphibians such as the long-tailed salamander and reptiles like the green-and-black lizard and the Seoane viper become visible with the rise in temperatures. Summer allows for comfortable walks along the routes that cross the higher areas, such as the brañas, or the trails nestled between mountains, enjoying the lush forest. Autumn, for its part, turns this area into one of the most desirable destinations for landscape photography: the beech trees turn chestnut, the rowan trees turn reddish, the birch trees yellow, and the oak trees mutate into ochre, orange, and gold tones, which shine with particular intensity under the grazing light of the autumn sun.
Furthermore, late summer and early fall are the best times to try to spot the brown bear from strategically designated viewing points, always accompanied by specialized guides who guarantee a respectful experience for the species and its habitat.
In the Fuentes del Narcea, Degaña, and Ibias Natural Park and Biosphere Reserve, you can engage in a variety of activities related to the discovery of nature, the landscape, and the traditional culture of western Asturias. Interpretive routes guided by local companies allow you to explore this territory at a leisurely pace, combining the enjoyment of the environment with an insight into its ecological and human values. One of the main attractions is a visit to the Muniellos Forest, a forest jewel of the Cantabrian Mountains, access to which is limited to small groups to preserve its extremely high ecological value. Furthermore, this area stands out for its inhabitants' commitment to preserving its heritage, restoring traditional trades, and passing on ancestral customs that enrich the visitor experience and strengthen the connection with the rural environment.
Wildlife observation is another major attraction, with real possibilities of detecting signs of the presence or sightings of large mammals such as the brown bear, the Iberian wolf, and various wild ungulates. In spring and autumn, it is also possible to identify rare amphibians, such as the long-tailed salamander, and enjoy landscape photography, especially during the forest's seasonal changes. The area also offers the opportunity to discover unique ethnographic elements, such as cortines, talameiros, hórreos, and mills, and immerse yourself in an authentic rural culture represented in isolated villages and the Cunqueira tradition, linked to the artisanal work of wood.
The Fuentes del Narcea, Degaña, and Ibias Natural Park offers numerous points of interest that allow you to discover its scenic, forest, and cultural riches. One of the most emblematic sites is Muniellos, with its primeval oak forest. Access is strictly regulated to preserve this unique ecosystem. Thus, daily entry is limited to a maximum of 20 to 40 people, who must reserve in advance. Entrance to the Muniellos Integral Reserve is from Las Tablizas. Oubacho, meanwhile, is home to both the viewpoint, which offers breathtaking panoramic views of the oak forest, and the Muniellos Interpretation Center, where visitors can better understand the ecological and historical value of this area.
In the municipality of Cangas del Narcea, the area surrounding Monasterio de Hermo is home to the largest and one of the best-preserved beech forests in Asturias. The Leitariegos road—which follows the route of the old Camino Real, a historic communication route between the mountain passes of western Asturias and the Meseta—allows you to explore a landscape of great cultural and natural richness. At the bottom of the valley, traditional vineyards give way, as you ascend, to high-altitude meadows and villages such as Brañas d'Arriba, from where you can enjoy one of the most beautiful views of Cuetu d'Arbas, one of the highest peaks in the western Cantabrian Sea. This mountain bears the traces of the last ice age on its slopes, witness to the region's geological past. Sheltered by the Cuetu River lies the Arbas lagoon, of glacial origin, whose shores are home to a remarkable biodiversity of amphibians such as the alpine newt, the Iberian newt, the palmate newt, and the common frog, which find a privileged habitat here.
In the municipality of Ibias, notable sites include the Furacón viewpoint in Sisterna, which offers exceptional panoramic views of the surrounding area. Finally, in Degaña, the Corza viewpoint, on the forest road from Valdeprado to Trabáu, is worth a stop. It offers one of the most authentic and wild landscapes in western Asturias.
