Shelter - Cabeza Líjar
It is located at the top of Cabeza Líjar, under the circular viewpoint at the top.
It is a bunker of the civil war reconverted to lookout and refuge.
As a refuge, it may be good to avoid wind and rain, but it has no door. A few years ago I had a hard plastic door-like plate, but now (Dec-2012) it is not there and snow enters the shelter.
