Operated by Peru Andes Top · Soraypampa, Cusco Region
A pre-dawn van eases out of Cusco and the Andes press close—rock faces, distant glaciers and the slow light along the Apurímac valley. By Soraypampa you step out into thin, cold air; the trail climbs quickly through puna grass and rock, and the lake appears as a shock of blue above the switchbacks, a suspended pool fed by the glacier tongues of Nevado Humantay.
moderate.
6–12 hours (door-to-door, depends on pickup and stop times).
Moderately fit: able to hike on steep, uneven ground at altitude for several hours
The uphill distance is roughly 2–3 km one way with 300–400 m of elevation gain; plan 1–2 hours each way depending on fitness and acclimatization.
Possibly—at 4,200 m some people experience headaches or nausea; acclimatize in Cusco, hydrate, and descend if symptoms worsen.
Physically capable children and fit older adults can do the hike, but it’s slow and steep; consult a guide and consider oxygen support if needed.
The dry season (May–September) offers the most stable weather and clearer views; the wet months (Nov–Mar) can be muddy and cloudy.
Local Quechua communities consider high peaks like Humantay sacred (apus); the area sits within routes historically used for seasonal grazing and pilgrimage.
The lake and surrounding puna are fragile—stick to established trails, pack out all waste, and respect local offerings to minimize impact.
