This classic Cordillera Blanca route is the most popular trek in northern Peru. We offer this trek on a custom or private basis. Traversing a challenging 5-day route, you enjoy one of the Peruvian Andes most spectacular experiences. We include 2 acclimation day hikes before you set off on the main route. This allows your body to slowly, properly adjust to the altitude. All around you, the mountain summits reach heights exceeding 6,000 meters. Close by you are beautiful turquoise lakes, native queñual forests, and the golden bunches of ichu grass of the high Andes moorlands. We cross the Punta Union Pass (4,750m) and the Llanganuco Pass (4,765m), enjoying the views of the most famous peaks in the Cordillera Blanca.
