The Alhorí springs appear during the climb, they spring up at the foot of the cliffs, in the peat bogs or come out from between the stones on the path. The route goes over the steps carved during the glacial modelling process that designed the current reliefs of the Sierra Nevada mountains and reaches the isolated glacial cirque of the Ventisquero del Carbón, where the highest sources of the Alhorí are. It is amazing to find a trickle of water and green bushes in such a desolate and solitary place of pure rock. The path has stone milestones and continues clearly to the right of the spring towards the bottom of the cirque, there is still a good steep slope to the summit of the Picón.
