A two-day, high-altitude trek to Quelccaya — the world’s largest tropical glacier — offering stark glacial scenery, high puna terrain, and close-up views of ice that climate scientists study for centuries of data. Best attempted in the dry season with prior acclimatization.
More ways to explore the area's outdoor wonders
You step from the van into thin air and a bowl of white opens ahead — the Quelccaya Ice Cap pressing a hard, bright edge against the high Andean sky. Dusty puna grass gives way to rocky moraines; wind scrubs the landscape and the glacier seems to move in silence, an ancient current of ice daring you to approach.
Difficulty

Duration
2 days (approx. 48 hours)
Fitness Level
High level of cardiovascular fitness and prior high-altitude trekking experience recommended; be prepared for sustained steep sections and heavy breathing above 4,500 m.
Wildlife
History
Quelccaya has been studied for decades; ice cores recovered here provide one of the longest tropical climate records and show rapid modern retreat as temperatures rise.
Conservation
The ice cap is retreating due to climate change; visitors should minimize footprint by camping on durable surfaces, packing out waste, and following local guide protocols.

Acclimatize in Cusco for 48–72 hours
Spend at least two nights in Cusco or the Sacred Valley before starting to reduce risk of altitude sickness.
Hydrate and eat frequently
Drink small amounts often and include salty snacks to help maintain electrolyte balance at altitude.
Sturdy boots and gaiters
Expect rocky moraines and loose scree; ankle-supporting boots and gaiters keep feet protected and dry.
Layer for rapid weather shifts
Sun is strong by day and nights drop below freezing—use a breathable base layer, insulating mid-layer, and windproof shell.
Insulated sleeping bag (-10°C rating)
Nights on the puna are very cold; a warm sleeping bag is essential for comfort and safety.
winter
High-ankle, waterproof trekking boots
Support and waterproofing reduce fatigue on rocky, variable terrain and during wet spells.
Trekking poles
Poles improve balance on moraine and reduce strain on knees at altitude.
High-SPF sun protection (sunglasses and sunscreen)
Clear skies and high elevation increase UV exposure—protect skin and eyes.
