Cordillera Blanca, Mountain range in Ancash department, Peru.
Cordillera Blanca is a mountain range in the Andes of Ancash containing more than 700 glaciers and numerous peaks exceeding 6,000 meters. The massif extends across 200 kilometers and holds one of the world's largest concentrations of tropical glaciers.
The first successful climb of Huascarán occurred in 1932, marking the start of modern mountaineering in the region. This expedition opened the range to international climbers and established it as a major destination for alpinists.
The mountain range holds deep spiritual meaning for local communities, who perform rituals and ceremonies in honor of the peaks. These practices remain an active part of daily life and shape how people relate to the landscape around them.
The best time to visit is from May to September, when conditions are most favorable for hiking and climbing expeditions. Access is typically through the city of Huaraz, which serves as the main base for mountain activities.
The range acts as a continental divide, with rivers flowing toward both the Pacific and Atlantic Oceans. This geographic feature connects two major ocean basins and makes the mountains a rare hydrological crossroads.
