Shelter - Refugio de Bucierca
From Santander, take the Cantábrica-Meseta A-67 motorway where Torrelavega becomes the A-8 motorway of the Bay of Biscay and exit 244, take the CA-135 to the town of Cabezon de la Sal where the AC takes off. -180 Saja where in 2.5 km there is a forest track, which is the beginning of the route.
The crossing between the towns of Saja and Tudanca is described, whose route is part of the Saja-Besaya Reserve trail, GR-71.
Saja and Tudanca are in the valleys of the river basins of the Saja and Nansa rivers, which, in more or less parallel lines, are separated by a mountainous mountain range that divides the waters. It's about moving from the Saja Valley to the Nansa Valley.
Cabezón de la Sal to the Port of Palombera, specifically two kilometers after the village of Saja on the right is the forest road that we must take. At this point we find a sign indicating the route. At the same point we parked the car.
We started to walk along a wide track in which the circulation of vehicles is prohibited. The road is slightly ascending and is gaining height. The track crosses a forest of beech trees. During the ascent we find some secondary path that we do not have to pay attention to, but all we have to do is follow the main trail until we reach the Bucierca refuge.
The shelter is extended to shelter the cattle, and that at one end is used as a refuge with a couple of bunk beds (3 mattresses), table and stove / fireplace.
