The starting point for this activity will normally be from the Cabrones refuge, although it can also be done from the Vega de Urriellu refuge.

The meeting point will be at Vega de Urriellu shelter, and the timetable will depend on the place of overnight stay, the guide will give prior notice when booking the activity.
If the overnight stay is in the Urriellu shelter, we will make the approach very early in the morning to the corona del raso and from there to the Horcada Arenera by the spectacular path where we can see an incredible sunrise with the Cantabrian Sea as a backdrop and the spectacular Urriellu behind us.

After reaching the Horcada Arenera, we will descend a few meters and after passing some Jous and climb a few meters we will reach the Bivouacs in the pass that separates the impressive Jou Negro from the Jou de Cerredo. (Up to this point about 2 hours walking from Urriellu). At this point we will get ready with the material and start walking on short rope under the Torre La Brouche and over the perpetual snow of the Jou Negro to access the north steps that give access to the Noth Spur (30 minutes approximately).

After successive relatively easy climbs and some rope lengths, we will reach the north shoulder where the most vertical and excellent rock climbing begins. In four pitches of climbing of maximum enjoyment we will reach the end of the route under a large orange overhang, from where in short rope we will access the summit by means of some easy climbs.

Once at the summit, after taking pictures and having a snack, we will begin the short rope descent by the normal route until we reach the Bivouacs. (approximately 1 hour from the summit). From this point we only have to undo the same path to the Vega de Urriellu (about 2 hours).
