Natural Park of the Fuentes del Narcea, Degaña and Ibias.
Path: Mines of Gold of the Corralín
The route of the Mines of Gold takes us by Sisterna, that is in the council of Ibias. In its landscape they emphasize chestnuts, that are plantations realized by the man with aims of aprovechamiento, of the wood or of the fruit. In most cases, the castañedo occupies a band close to the meadows, that is, the lower and lower slopes of the slopes and therefore more easily exploitable.
In the vicinity of towns and villages, it is common to find cabornos, old trees of large size and hollow trunk that were peeled to increase fruit production, while the rest of the plantation was used for logging.
The auriferous wealth of the zone was intensely exploited during the Roman domination. The cuts are still visible in the landscape of the area, as in the surroundings of the Corralín, of which a popular saying is said: «Corralín, golden bowl, you throw a stone and a treasure appears

In the  Mountain of the Picos de Europa  and especially in its foothills, there is one of those paradises to enjoy enormously «The Garganta del Río Casaño, or Casañu, is a path on the margin of a very crystalline and capricious river of forms that passes through esculti , majadas, foces and castañeos and crossing it by singular bridges.There we will see the old caves to keep the cattle and ancestral hen houses or circular stone cochineras.
