We went up from "la Granja de San Ildefonso" to Alto de los Neveros. From Alto de los Neveros we went down to Puerto de los NEveros and then, by Risco de los Claveles up to Peñalara. Going down we went up Hermana Mayor. From Hermana Mayor we went down to Zabala hut, and then, going along Peñalara lakes to Puerto de los Neveros. Then we went back to la Granja, after about 9 hours.
In my opinion much more interesting than from Cotos.
