Shelter - Collado de San Martín
The refuge of Collado de San Martín is located at the border crossing of Belagua, a point of union between France and Isaba.
It is a refuge that consists of two parts, one of them closed. The open part consists of a single compartment with a small chimney, a broken window and a metal door.
From here, there are mythical routes such as the ascent to Anie peak or Arlas.
