A classic four-day trek through the Cordillera Blanca, in the Huascarán National Park, from the Llanganuco lakes to the Santa Cruz valley.
From Huaraz, the route runs along the Callejón de Huaylas with views of Huascarán (6,768 m), Peru's highest mountain, and climbs the Portachuelo de Llanganuco (4,767 m), between the Chinancocha (3,850 m) and Orconcocha (3,870 m) lakes. The trek crosses the Huaripampa ravine and the Punta Unión pass (4,750 m), with views of Chacraraju, Taulliraju and Artesonraju, and reaches the Alpamayo (5,947 m) base camp by Lake Arhuaycocha (4,450 m). The descent follows the Santa Cruz ravine to Cashapampa (2,900 m) to return to Huaraz. All three nights are spent camping.
