The Cordillera Blanca (Spanish for "White Range") is a mountain range in the Ancash Region of Peru. Part of the larger Andes range, it includes 33 major peaks over 5,500 metres (18,040 ft) high in an area 21 kilometres (13 mi) wide and 180 kilometres (112 mi) long.
The 5,947 m (19,511 ft) Alpamayo mountain was declared "World's Most Beautiful Mountain" by an international survey led by former climber Tonni Hiebler in May 1966 in Münich.
Snow melt from the Cordillera Blanca has provided Peru with its year-round water supplies, while 80% of Peru's power comes from hydroelectricity. The area of permanent ice pack shrank by about a third between the 1970s and 2006.
There are sixteen 6000m peaks in the Cordillera Blanca with a 400m topographic prominence, and a further seventeen peaks over 5500m. Huascaran Sur, the highest peak, has two commonly quoted heights - 6746m from the Peruvian IGM map, and 6768 from the OEAV survey map.

The estimated number of glaciers is 260 glaciers of the Cordillera Blanca are very important to life in the valley of the Callejón de Huaylas. They provide water for the irrigation of the puna grasslands and keep the main Santa river drought free year round. They also support the hydroelectric powerstation of Cañón del Pato and form many attractive lagoons. All are over 4000m above sea level, 185 on the western slopes and 75 on the eastern.
As with all Andean glaciers, the Cordillera Blanca has witnessed a major retreat of its during the 20th century due to global climate change. Studies have shown a retreat of over 15% since the 1970s. Some glaciers, such as the Broggi Glacier, have disappeared altogether, with many experts warning that all of the glaciers may be gone within the coming decades.
Other famous lakes include the two Llankanuku Lakes: the green-turquoise Chinanqucha (female lake) and Urqunqucha (male lake) in the Llankanuku valley. Located in the quenoa forests at the foot of Huáscarán, they are reachable via a 25 km gravel road off the Callejón de Huaylas highway near the re-built town of Yungay.
Hot Springs 
There are twenty-two principal hot springs in the Callejón de Huaylas, of which the 2073m above sea level Monterrey stands out for its swimming pools and individual and family ponds. Bathing in its 49 °C sodium chloride laced water is prescribed for such health conditions as rheumatism, anxiety, and palsy.
