A high-altitude full-day trek from Cusco to Laguna Humantay that rewards a steady climb with a vivid turquoise glacial lake and dramatic Salkantay views. Expect long drives, thin air and quick-changing weather; acclimatization and layers are essential.
More ways to explore the area's outdoor wonders
You step out before dawn in Cusco and the van threads uphill, townsblinking away as Andean air sharpens. Three hours later the road delivers you to Soraypampa at about 3,800 m; the trail yawns into a high pampa with wind that seems to measure your lungs. The climb is steady—two hours of switchbacks and stony steps—until the lake reveals itself in an impossible turquoise bowl beneath the glaciated flanks of Humantay.

Acclimatize in Cusco first
Spend 24–48 hours in Cusco before the trek to reduce altitude sickness risk—stay hydrated and rest the day before departure.
Start early for better light
Departing at 5AM means cooler trails and crisper photos; afternoon clouds often roll in during the wet season.
Sturdy footwear and poles
Trail is rocky and can be slippery on descent—ankle-supporting boots and hiking poles make the return much easier.
Pack for temperature swings
Carry a warm insulated layer and waterproof shell; temperatures at 3,800–4,200 m swing dramatically between sun and shade.
Insulated jacket (down or synthetic)
Cold temperatures at the lake and on the ridge make a warm layer essential for rest stops and photos.
Sturdy hiking boots
Support and grip on rocky, uneven trails reduce ankle strain during ascent and descent.
Hydration system (2L+)
High-altitude exertion requires regular fluid intake; bring water and electrolyte options.
Sun protection (hat, sunglasses, SPF)
Thin high-altitude sun increases UV exposure—bring a broad-brim hat and high-SPF sunscreen.
