Casteñedón
A chestnut grove near the village of Riellu containing several hundred-year-old specimens, surrounded by various myths and legends.
The chestnut is a vital tree in the area; its fruit, the chestnut, was a staple food in the past and remains a key ingredient in numerous typical dishes of these valleys.
It is a very robust, deciduous tree that can reach up to 30 metres in height. Its bark is ashen or brownish, and deeply fissured. It has large leaves, from 10 to 25 cm, with a lanceolate shape and a coarsely serrated edge.
Its fruit is the prized chestnut, which develops inside a prickly burr containing 1 to 3 chestnuts.
It is a tree that grows on cool, loose and deep soils, in a moderately humid climate without severe droughts or winter frosts, which is why it thrives best in these forests.
In autumn, its leaves turn a bright yellow colour, lending a beautiful hue to these mountains, and together with a multitude of burrs, they cover the ground at many points along the Nature Trail.
