A full-day trek from Cusco to the vivid blue Humantay Lagoon beneath the Salkantay massif. Expect steep switchbacks, thin air, and glacier-fed views—ideal for acclimatized hikers who want a high-altitude lake experience without multi-day camping.
More ways to explore the area's outdoor wonders
The road climbs out of Cusco before sunrise and the air thins until the peaks begin to assert themselves: slabs of granite, wind-scoured moraine, and a fringe of snow that flashes like metal. By Soraypampa the bus stops and the trail pulls you upward—an hour and a half of switchbacks, puna grass, and the occasional gust that seems to push you toward the glacial bowl where Humantay Lagoon sits, bright and impossible against the sky.

Acclimatize before you go
Spend 24–48 hours in Cusco doing light activity to help reduce altitude sickness risk; stay hydrated and avoid heavy meals the night before.
Start early
Morning departures avoid afternoon storms and give the best light on the lagoon; crowds are smaller at first light.
Bring cash for facilities
Restrooms and small vendors at Soraypampa often accept cash only; carry small bills for snacks or tips.
Use trekking poles
Poles reduce strain on knees during steep climbs and descents and help conserve energy at altitude.
Sturdy hiking boots
Support and traction on rocky, sometimes muddy trail surfaces.
Warm insulating layers
Temperatures drop fast at the lagoon—fleece and a windproof shell are useful.
winter
Sun protection (hat & sunscreen)
High-altitude sun is intense; sunburn and glare are real hazards.
summer
Trekking poles
Improve balance and reduce effort on steep sections and loose scree.
