Very beautiful circular route, recommended on clear days. It can be done both ways.
Once we leave the center of Sodupe, we head to the Iorgi neighborhood, to access the Grazal through an unusual path, which will take us fully into the Grazal biotope.
Starting at kilometer 5, and after passing the fence, we will see our goal: the summit of the Eretza, which we will gradually approach and gain height until we reach the refuge.
Once we have passed the refuge, and are on the track, we take an unusual variant, through a path that is not very busy and owns a great slope overlooking the field to the top: 887 m with unbeatable views of its famous firewall.
Once here, we will go back to start the descent through the path and the forest to the firewall and continue descending on its way out along a technical path with unevenness that will require a great deal of technique and concentration to avoid unnecessary scares on the way to the Saratxo neighborhood.
From here, we will go down the track to La Quadra to reach the Kadagua route and return enjoying the stretch to the starting point.
