  • Mount Peloño is located in the southeastern part of Asturias, very near to the province of León. It falls entirely within the borough of Ponga. The Nature Reserve occupies a total area of 1,507 hectares, mostly belonging to the villages of San Juan, Casielles, San Ignacio and Viego.

  • Plant life

    The area occupied by woodland is very nearly the estimated total area of the reserve. However, this woodland is interspersed with small, deforested areas of grassland and pasture or covered by different types of shrub. The deciduous forest is the most representative element of the Peloño landscape. Coverage by beech trees has reduced the amount of light reaching the undergrowth, imposing severe competition for other species such as small populations of oak. In the high mountains, common juniper thickets abound, with bearberry on the limestone crags and heather and bilberry in areas of siliceous subsoil.


    All the elements that make up the rich wildlife of the eastern-central mountains are represented in this area. Bears have been sighted in Peloño Forest and the surrounding area, where the eastern population of the Cantabrian Mountains sets the limit to the area they range to the west. Significant populations of chamois are also found here, as well as plenty of wolves. The existence of relatively extensive forested areas favours the presence of capercaillie, with particularly interesting populations on Mount Peloño. There are a large number of species of other kinds of birds, as well as of reptiles and amphibians, favoured by the conservation of their habitats.

Peloño Forest Nature Reserve is one of the most emblematic forests in Asturias.

It offers a unique palette of colours in the autumn on account of its lush forest of native species.

Its boundaries basically delimit the catchment area of Canalina Stream, with a maximum elevation at Pileñes Crag (2,012 m) and a minimum elevation of 900 m at the gorge leading to the confluence of this stream with the River Mojizo. The ground is characterized by the overlap of two lithologic units, one massive, resistant unit made up of quartzite and mountain limestone and another consisting of shale-like materials. Their combination gives rise to thrust faults that are repeated throughout the sector and, as in the rest of the Cantabrian Mountain Range, traces of glacier landforming can be seen in its cirques and small moraines.

Though small in extension, every corner holds a surprise, such as the Majada de Arcenorio high meadow, with its chapel devoted to the Virgin Mary and the impressive Ten Crag.
