You arrive before dawn, the van cutting through Andean night toward a rim of gray mountains. At Soraypampa the air is thin and sharp; lamps click off and a column of hikers sets off uphill. The trail climbs through puna grass and stone cairns, the slope steady and honest, until an emerald mirror appears: Humantay Lagoon, ringed by glacial moraine and watched over by the snow-capped hum of Humantay peak.

Acclimate first
Spend 48 hours in Cusco or at similar elevation before the hike to reduce altitude sickness risk.
Start early
Begin before sunrise from Soraypampa to avoid afternoon cloud build-up and crowded viewpoints.
Use trekking poles
Poles reduce load on knees during the steep ascent and descent and improve balance on rocky sections.
Respect sacred sites
Do not disturb offerings or leave litter; local communities maintain spiritual ties to the lake and peaks.
Layered windproof jacket
Wind and sun are common at altitude; breathable layers protect against rapid temperature shifts.
Sturdy hiking boots
Support and traction are important on loose scree and rocky steps during ascent and return.
Trekking poles
Help with balance and reduce knee strain on the steep, uneven trail.
Water and electrolyte mix (1–2 L)
Hydration aids acclimatization and keeps energy steady in thin air.
