Pastoruri Glacier
Ancash
Pastoruri Glacier is a cirque glacier located in the southern Cordillera Blanca of the Peruvian Andes, within the Ancash region. It spans approximately 8 square kilometers and stretches about 4 kilometers in length, perched at an elevation of around 5,250 meters above sea level. Characterized by steep, cliff-like edges and heavily crevassed terrain, it is one of the few remaining glaciers in tropical South America. The glacier has been rapidly retreating over recent decades, losing significant ice mass and surface area due to climate change. Despite this, it remains a popular destination for tourists, snowboarders, and ice climbers attracted by its unique high-altitude environment. Efforts to slow its melting include experimental insulating techniques using sawdust layers, which have shown some local success but cannot halt the overall retreat. The glacier is part of the Huascarán National Park, a UNESCO World Heritage site, highlighting its environmental and cultural importance. Visitors can also engage in educational tours focused on climate change impacts, making Pastoruri not only a natural wonder but also a center for environmental awareness.

Tip: The best time to visit Pastoruri Glacier is during the dry season (April to November) when weather conditions are more stable. Visitors should prepare for high altitude and cold temperatures. It is recommended to book guided tours in advance, especially for ice climbing or snowboarding activities. Informational talks about climate change impacts on the glacier are often offered by park specialists. Although the glacier's retreat has led to some access restrictions in the past, current tourist circuits like “The Climate Change Route” provide safe and informative experiences. Discounts may be available for students and groups through the national park services.
Interesting facts
- •Pastoruri Glacier is one of the few glaciers located in tropical South America.
- •It has lost over 20% of its surface area in the past three decades due to climate change.
- •Local glaciologist Benjamin Morales Arnao pioneered an insulating method using sawdust to reduce ice melting.

History
Pastoruri Glacier has historically been a prominent ice mass in the Cordillera Blanca, originating from elevations above 5,200 meters.
Over the last 30 to 35 years, it has lost approximately 22% of its surface area and 15.5% of its ice mass, reflecting rapid glacial retreat due to rising temperatures.
In 1985, the glacier became part of the Huascarán National Park, designated a UNESCO World Heritage site.
Since 2007, visitor access was temporarily suspended due to adverse climatic conditions and safety concerns but resumed in 2011 with new tourist circuits emphasizing environmental education.
Local glaciologists have experimented with insulating the glacier with sawdust to slow melting, achieving some localized ice preservation.
