An early start and steady legs reward hikers with a quiet hour at Humantay Lagoon—an emerald alpine bowl beneath the Salkantay peaks. This high-altitude day hike is short but demanding; acclimatize, layer up, and plan for dramatic glacier-and-lake scenery.
More ways to explore the area's outdoor wonders
Dawn breaks over the jagged rim of the Salkantay massif and the air sharpens against your face as you climb toward Humantay Lagoon. The trail climbs from the high puna through windswept grass and patches of ichu, opening suddenly onto a bowl of turquoise water cradled beneath a glacier-tipped peak. The lake holds the colors of the sky and the pace of the mountain—both indifferent and commanding.

Acclimatize first
Spend 48–72 hours in Cusco or a similar altitude before this hike to reduce risk of altitude sickness.
Start very early
Arrive at the trailhead before sunrise to avoid crowds and to catch calmer wind and better light at the lake.
Footwear and poles
Sturdy hiking boots and trekking poles help on steep, loose sections and on rocky descent.
Hydration and snacks
Carry at least 1–2 liters and high-energy snacks—altitude increases fluid needs and effort makes you hungrier.
Hiking boots
Support and traction on steep, rocky and sometimes wet trail sections.
Trekking poles
Reduce strain on knees during ascent and descent and improve balance on scree.
Layered clothing + wind shell
Temperatures swing quickly—insulating mid-layer and windproof shell are critical.
Water and electrolytes
Altitude increases dehydration risk; carry at least 1–2 liters and electrolyte tablets.
