A brisk, high-altitude day hike from Cusco that rewards steady breathing and firm boots with a striking turquoise lagoon below snowy peaks. Expect a steep 1–2 hour climb, glacier-fed water, and a full-day return to the city.
More ways to explore the area's outdoor wonders
Before sunrise the road uncoils from Cusco and the Andes open like a switchbacked map—dusty villages, terraced hills, and finally the thin-air plain at Soraypampa (3,850 m). From that high meadow a sharp band of rock and moraine gives way to an unexpected bowl of turquoise: Humantay Lagoon, fed by glacier melt from the Salkantay massif. The water looks foreign at this altitude, a vivid bank of color daring you closer.
Difficulty
moderate
Duration
6 hours
Fitness Level
Moderate cardiovascular fitness; ability to hike uphill at high altitude for 1–2 hours is recommended. Acclimatization is important.
Wildlife
History
The lake sits in a glacial basin beneath Salkantay, a peak long revered in Quechua tradition; nearby routes follow pre-Columbian and Inca-era corridors used for trade and pastoralism.
Conservation
Fragile alpine soils are vulnerable to erosion—stick to established paths, avoid trampling high-altitude vegetation, and pack out all waste.

Acclimatize before hiking
Spend 24–48 hours in Cusco to reduce risk of altitude sickness—stay hydrated and avoid alcohol the night before.
Start early
Departing around dawn reduces exposure to afternoon weather and gives you clearer views at the lake.
Layer for wind and cold
Temperatures can swing quickly; bring a windproof outer layer and an insulated mid-layer for the lake viewpoint.
Watch footing on scree
The final approach includes loose gravel—use trekking poles if you need extra stability and descend carefully.
Sturdy hiking boots
Good traction and ankle support help on steep, rocky and occasionally loose sections.
Warm layers + windproof jacket
Cold, wind and sun can alternate quickly at elevation—insulation and a shell are essential.
Sun protection (hat, SPF, sunglasses)
High UV at altitude makes sun protection critical even on cool days.
Trekking poles
Optional but helpful for steadying descents on scree and reducing knee stress.
