From Portilla del Crampón (see route) descend lightly to the NW (towards Portilla de los Cobardes) crossing a narrow gravel field. Start on a little arête dividing the two couloirs at both sides of Cuerno.
This little peak of 2.538 m is situated SouthWest of Almanzor over Canales Oscuras. Offers a great view to the South Side of Almanzor. At its foot a plaque recalls a death happened on Cuerno. Find the most logic route on the rocks of the face, easy and clear climb above a series of little projections and ledges.
Its climb don´t require rope by this route. In Summer this is a short and easy climb above rocky blocks, meanwhile in Winter needs some care because the rocks use to be covered by ice or snow.
