Leave early from Cusco for a full-day ascent to Humantay Lake, a glacial turquoise basin beneath snow-capped peaks. This moderate high-altitude hike offers dramatic scenery, cultural context, and practical access for travelers acclimated to the Andes.
More ways to explore the area's outdoor wonders
Dawn in Cusco feels like a held breath: vans slip into the dark and the Andes loom larger with every kilometer. By mid-morning you arrive at Soraypampa, a high plain where wind carves clear lines across the grass, and the trail angles upward toward a bowl of water that looks almost unreal. The hike to Humantay Lake climbs through thin air and rocky switchbacks, revealing the glacier-polished face of nearby peaks and a mirror-blue lake that seems to have been poured into the valley.

Acclimate in Cusco
Spend 24–48 hours in Cusco before the hike to reduce altitude sickness risk and move slowly on the trail.
Hydrate and snack
Bring 1.5–2 liters of water and high-energy snacks—altitude increases sweat and exertion even in cool weather.
Protect from sun and wind
High-altitude sun is intense—use sunscreen, sunglasses, and a windproof outer layer for the lake-side exposure.
Consider a horse for the ascent
Local mule rentals can shorten the climb; confirm availability in advance and check animal welfare practices.
Layered clothing (base, insulating, windproof)
Temperature swings are large at 4,200 m—layers keep you comfortable from dawn chill to midday sun.
Sunscreen and UV sunglasses
High-altitude UV exposure is intense; protect skin and eyes during the exposed summit sections.
Sturdy hiking shoes or trail runners
Trails include rocky, sometimes slippery sections where ankle support and grip matter.
Hydration system and electrolyte snacks
Carry 1.5–2 L water and quick calories to maintain energy on the climb.
