In the final stretch of the ascent, milestones appear in several places and the best option is to find the optimal path according to the moment, the mountain conditions and personal taste. The geodesic vertex is visible long before you arrive, it is placed on a tower of rocks and the views are extraordinary, practically covering the entire Central System, from the Sierra de Guadarrama to the peaks of Las Batuecas and the distant Sierra de Gata. Below the channels that form the sources of Corneja and Adaja and a little further on is the valley of the highest Alberche, when it is not yet a river in the páramos of San Martín de la Vega del Alberche.
