A pre-dawn transfer from Cusco leads to a steep 1–1.5 hour ascent to a glacial turquoise lake beneath Salkantay. This one-day high-altitude hike rewards effort with vivid views and cultural context tied to Inca reverence for the apus.
More ways to explore the area's outdoor wonders
You leave Cusco before dawn, the city lights shrinking as the bus threads down into the Apurímac valley. Mountain air sharpens with altitude; by Soraypampa (≈3,900 m) the sky is thin and bright. The trail climbs steep, rocky switchbacks through puna grass and stunted shrubs, the snow-capped mass of Salkantay watching like an old guardian. Humantay Lake appears suddenly — a bowl of glacial turquoise cupped beneath serrated ridgelines — and the climb’s effort falls away against that colour and space.

History
Humantay and Salkantay are part of landscapes long held as sacred by local Quechua communities; mountains (apus) were central to Inca ritual and local cosmology.
Conservation
The alpine lake sits in a fragile glacial environment—stick to paths, pack out waste, and avoid disturbing water sources to protect meltwater and vegetation.

Acclimatize before you go
Spend 24–48 hours in Cusco doing light activity to reduce acute altitude effects; headaches and breathlessness are common without acclimation.
Start early to avoid crowds and weather
Tours leave around 3:30–4:00 a.m.; arriving at Soraypampa before mid-morning gives clearer skies and quieter views at the lake.
Carry 1–2 liters of water and electrolytes
Thin air at 4,200 m increases dehydration—sip regularly and bring salty snacks to maintain energy on the steep climb.
Wear grippy footwear and bring trekking poles
The trail is steep and rocky; poles ease the descent and boots reduce ankle-rolling on uneven switchbacks.
Sturdy hiking boots
Support and traction on steep, rocky ascending and descending trails.
Insulating layers and windproof shell
Temperatures swing quickly at altitude—layer to trap heat and block wind.
Sunglasses and SPF lip/sunscreen
High-altitude UV is intense even on cool days; protect skin and eyes.
summer
Daypack with 1–2 L water and snacks
Hydration and calories are critical for steady effort and altitude tolerance.
