A brisk, high-altitude day hike from Cusco leads to Laguna Humantay, a vivid turquoise glacial lake beneath Salkantay. This full-day outing combines a cultural coca ritual, dramatic mountain views, and a moderate but steep 3 km ascent.
More ways to explore the area's outdoor wonders
The trail opens under a slate-blue dawn as a convoy leaves Cusco, the city lights shrinking behind you and the Andes rising ahead. By the time the bus spills hikers into Mollepata, the air has thinned and the road climbs into a landscape of wind-sculpted puna and serrated peaks. The final walk from Soraypampa pushes past low shrubs and rocky switchbacks until a bright bowl of turquoise water appears at 4,200 m — Humantay Lake, fed by the glacier of the Humantay massif.

Acclimatize before you go
Spend 24–48 hours in Cusco to reduce altitude sickness risk; ascend slowly and hydrate well.
Start early for better light
Departing at dawn improves weather odds and gives clearer views and calmer winds at the lake.
Consider a horse for the steepest sections
Local horses are available on-site for a fee and can help if you struggle with the climb at altitude.
Respect local rituals and environment
Observe the coca-leaf ritual and avoid leaving trash; trails and sacred sites are culturally sensitive.
Layered insulating jacket
Light down or synthetic layers protect against cold mornings and windy exposure at the lake.
Sturdy hiking boots
Support and traction for rocky, uneven trail and occasional muddy sections.
Water bottle or hydration bladder (2+ liters)
High-altitude exertion increases dehydration; carry ample water and electrolytes.
Sun protection (hat, sunglasses, sunscreen)
High UV at altitude makes sun protection essential even on cool days.
