The Andes of Northern Peru are composed of three perfectly distinct mountain ranges: The western, central chain and the eastern chain

Western Chain: The chain is the highest, is called the Cordillera Huayhuash, northern Pasco Knot, its highest peak is the Yerupaja, the tuco node splits, forming the Cordillera Negra to the west and the Cordillera Blanca to the east.

The black mountain range has a lower altitude and lack of snow. Has been eroded by the Santa River in the Canyon of Pato. There he has built the power plant of the same name, whose energy has been used in Chimbote, Trujillo and cities in the Callejon de Huaylas.

The Cordillera Blanca is the largest in the country, not only to form an extensive area covered by glaciers and perpetual snows and persistent, but also exhibit the highest peaks of Peru. Among the main highlights: The Huascaran and Alpamayo Huandoy, the world's most beautiful peak.

The Cordillera Blanca is the most extensive tropical ice-covered mountain range in the world and has the major ice concentration in Perú. The Rio Santa runs through the Callejon de Huaylas in the direction from north to south between the villages of Ticapampa, Recuay, Huaraz, Carhuaz, Yungar, Caraz. This whole area is judged to be the capital of adventure (Trekking and Climbing)

The Cordillera Blanca has five of the most spectacular peaks above 6,000 m in the Peruvian Andes. The highest peak (Nevado Huascarán) rises to an elevation of 6,768 m. A total of 722 individual glaciers are recognized in the Cordillera Blanca.
