This great mountain range located at the southeast of Santiago, is a mountain range that divides the valley of Santiago with the Andean Cajón del Maipo. The trail runs along the edge of this pre mountain range giving us great views of the Andes, the coast range and the great city of Santiago (at night is incredible). On the way you reach the summit of Cerro Provincia, Cerro Tambor and Cerro San Ramón. With more than 2,500 meters of elevation gain, this crossing is only for true lovers of the Bigmountainbike. An experience only for experts.
