Barranco d’Os Cochás + Mascún Inferior

The approach to Barranco d’Os Cochás starts from the Rodellar parking, taking 2 hours and 15 minutes. The path involves an uphill walk past the houses of Cheto, crossing Barranc de la Virgen, and traversing a scree slope before descending off-path to the canyon bed. This route is often combined with Mascún Inferior, making for a long day.

R5 is a 20m rappel with a jump. Anchors are generally stainless steel parabolts and chemical bolts. The canyon is rated v4-a1-III, requiring a full wetsuit and 2x45m ropes. It is a dry canyon, but water conditions should be checked for Mascún Inferior. There are no escape routes mentioned for this combination. The descent of Os Cochás takes about 2.5 hours, with an additional 1.5 hours for Mascún Inferior. The return walk to Rodellar is 1.5 hours. The total route covers 14.37 km with a 674m vertical drop.
