Pastoruri Glacier

Glacier

Pastoruri Glacier is a high-altitude cirque glacier in the Ancash region of Peru, visited for its near-tropical ice, short high-Andean hikes and easy-access glacier scenery. Travelers come for panoramic mountain views, snow activities and to see a rapidly retreating tropical glacier.

Pastoruri Glacier essentials

Address: Huascarán National Park, Ancash region, Peru

Pastoruri sits in the southern Cordillera Blanca of the Peruvian Andes at roughly 5,250 metres above sea level and is an example of a tropical cirque glacier with steep, cliff-like edges and heavily crevassed ice. It is one of the few remaining glaciers in the tropical Americas and lies within the protected landscape of Huascarán National Park.

Historically the glacier covered about 8 square kilometres and reached roughly 4 kilometres in length; scientific monitoring shows rapid retreat, with a reported loss of about 22% of its area and 15.5% of ice mass over the last 30-35 years. Local conservation experiments - such as insulating ice with sawdust - have had limited, small-scale effects, and park scientists describe the feature as diminishing toward disappearance.

Visiting Pastoruri is straightforward for day-trippers based in the nearby Andean towns: the site often has soft snow and is popular with snowboarders and ice climbers in season, while non-technical visitors usually stay on marked approaches to view the snout and surrounding peaks. Conditions can be cold, windy and crevassed, so acclimatization, caution and respect for park rules are important when planning a visit.

  • Glacial snout and crevasses: The glacier’s steep snout and visible crevassed ice are the main attraction and illustrate the glacier’s cirque morphology and ongoing retreat.
  • Cordillera Blanca panoramas: High-elevation viewpoints offer wide views of surrounding snow peaks, ridges and the high-Andean landscape of Huascarán National Park.
  • Snow and ice activities: Short guided snow hikes, basic ice climbing and seasonal snowboarding are possible here with appropriate equipment and local guides.
  • Alpine plants and wildlife: The approach passes puna grassland and high-Andean flora, with opportunities to see hardy mountain plants and birdlife adapted to the cold.
  • Lessons on glacial retreat: Interpretive information and local guides can explain the glacier’s rapid shrinkage and small-scale conservation experiments carried out in the area.

When to Go

Best Time to Visit Pastoruri Glacier#

Clear, dry weather gives the most reliable access and views; heavy precipitation and fresh snow in the wet season can make approaches more difficult.

Dry season (best)
May - September · -9°C - 7°C (16°F - 45°F)
This period has the lowest precipitation and the clearest skies, making road access and visibility to the glacier more reliable for day trips.
Wet season (cloudier, snowier)
November - April · -6°C - 8°C (21°F - 46°F)
Rain and snowfall are more frequent, especially December to March, producing deeper snow cover and potentially trickier access or road closures.
Shoulder months
October and April · -6°C - 8°C (21°F - 46°F)
Transitional months can offer a balance between improving weather and fewer visitors, but conditions vary year to year so check forecasts locally.

Getting There & Around

How to Get to Pastoruri Glacier#

The usual base for visiting Pastoruri is Huaraz, the Andean hub for Cordillera Blanca treks; most visitors travel to Huaraz then arrange a day trip or tour to the glacier. The nearest major international airport is Jorge Chávez International Airport in Lima, from which road transfers or long-distance buses run to Huaraz.

From Huaraz the glacier is reached by road into the high Cordillera Blanca; expect a full-day excursion from Huaraz and a mountain-road approach with a short walk from the parking area to the glacier viewpoint. Local tour operators, shared minibuses and private transfers cover the last stretch - check current road and park conditions locally before you go.

Tips for Visiting Pastoruri Glacier#

  • Spend at least one full day in Huaraz or nearby to acclimatize before ascending to the glacier altitude.
  • Dress in warm layers, bring windproof outerwear, high-SPF sunscreen and sunglasses for strong high-altitude sun and snow glare.
  • Do not attempt to walk onto heavily crevassed ice without a qualified guide, rope and appropriate equipment.
  • Check current park access rules and weather locally, as conditions and permitted activities can change with the season.
  • Respect the fragile high-Andean environment and follow Leave No Trace principles when visiting the glacier and surrounding trails.
