Before sunrise a fleet of minibuses threads down the mountain road from Cusco, and by first light the air at Soraypampa is thin and sharp. The trail climbs quickly—stone steps and packed earth switchbacking through puna grass—then opens to a bowl where the Humantay lagoon reveals itself: a slice of glacier-fed turquoise cupped beneath the serrated face of Humantay glacier.

Wildlife
History
Humantay sits along traditional Andean travel corridors below the Salkantay massif; local Quechua communities have long regarded nearby peaks as apus (sacred mountains).
Conservation
The high-altitude wetlands and fragile shoreline are sensitive—stick to trails, avoid single-use plastics, and use local guides who follow Leave No Trace principles.

Acclimatize before you go
Spend 24–48 hours in Cusco to reduce altitude sickness risk—take it slow and hydrate before the hike.
Layer for fast-changing weather
Temperatures swing dramatically; pack a breathable shell, warm mid-layer, and windproof outer layer.
Wear sturdy footwear
Expect loose scree and steep stone steps—supportive hiking boots with good grip make the ascent safer.
Respect the fragile shorelines
Stay on established switchbacks and avoid trampling the marshy areas around the lagoon to protect the ecosystem.
Water bottle or hydration system (2–3L)
High altitude increases dehydration; carry sufficient water and electrolytes.
Sturdy hiking boots
Provide ankle support and traction on rocky, uneven trail surfaces.
Insulating mid-layer and windproof shell
Protects against cold winds and rapidly changing mountain weather.
Trekking poles
Help with balance on steep ascents and reduce strain on knees during descent.
