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.
