A high‑altitude day hike from Cusco to the brilliant turquoise Humantay Lagoon with sweeping views of Salkantay. Expect a steep 2‑hour ascent to 4,180 m, strong sun, and rewarding alpine scenery—best after 48 hours of acclimatization.
More ways to explore the area's outdoor wonders
You climb out of the vehicle into thin, bright air at Soraypampa (≈3,900 m) and the first thing that hits you is the wind—cold, insistent, pushing at your jacket as if testing your resolve. The trail rises quickly into open high‑Andean slopes; after about two hours of steady ascent you crest a final switchback and the lagoon unrolls below, a sharp turquoise disk cupped by the glaciated shoulders of Humantay and the greater Salkantay massif.

Acclimatize First
Spend at least 48 hours in Cusco before attempting the hike to reduce risk of altitude sickness.
Use Trekking Poles
Poles reduce knee strain on the descent and help with balance on loose scree sections.
Sun and Wind Protection
High altitude means intense UV and fast temperature swings—bring sunscreen, sunglasses and a windbreaker.
Start Early
Leave Cusco by 5:00 a.m. to avoid afternoon storms and to get the best light on the lagoon for photos.
Sturdy hiking boots
Support and traction for steep, rocky and occasionally loose terrain.
Trekking poles
Improve balance on ascent/descent and reduce impact on knees.
Layered clothing and windbreaker
Quick temperature shifts require insulation plus a waterproof/windproof shell.
Water (2–3L) and high‑energy snacks
Hydration and fuel are crucial to cope with altitude and physical exertion.
