You leave Cusco before dawn, the city lights shrinking as the van threads down into the Apurímac valley. By midmorning the road levels out at Soraypampa and Salkantay’s snow-capped flank fills the windscreen — a hulking presence that seems to breathe cold air across the trail. The hike to Humantay is short but sharp: a steep ascent over puna grass and loose stones, then suddenly the trail opens onto a bowl of turquoise water carved by glacial melt.
Difficulty
moderate
Duration
9–10 hours
Fitness Level
Good aerobic fitness for a steady, steep 1 hour 40 minute ascent at high altitude; ability to walk on uneven trail for several hours is required.
Wildlife
History
Humantay and nearby Salkantay are part of the Andean Apu tradition; local Quechua communities consider these glaciers sacred and have long held rituals here.
Conservation
The high‑altitude puna is ecologically fragile; stick to trails, avoid trampling vegetation and pack out all trash to limit erosion and disturbance.
Reserve your spot on the Humantay Lagoon Full Day today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Acclimatize first
Spend 24–48 hours in Cusco to reduce altitude sickness risk — hydrate well and avoid heavy exertion the first day.
Use trekking poles
Poles ease the steep ascent and help on loose, precipitous dirt roads and rocky trail sections.
Dress in layers
Sun and wind alternate quickly at 4,200 m — a breathable base, insulating midlayer and windproof shell keep you comfortable.
Carry cash
Small vendors in Mollepata or near Soraypampa may accept only cash for snacks or tips.
Sturdy hiking boots
Support and traction on loose, rocky trail and muddy sections after snowmelt.
Insulating layer & wind shell
High‑altitude winds and sun require quick temperature control.
2–3 liters water and electrolyte mix
Hydration helps mitigate altitude effects and sustain energy on the climb.
Trekking poles
Reduce knee strain on the descent and stabilize on steep or uneven terrain.
