A thin morning light strips the valley as minibuses rattle out of Cusco before dawn, and by the time the village roofs shrink behind you the road has climbed into the high puna. The trailhead at Soraypampa opens onto a steep, clear track that rises through talus and high grass toward a bowl of glacier-fed water — Humantay Lake — framed by the fluted face of Humantay and the hulking mass of Salkantay.

Acclimatize before you go
Spend 1–2 days in Cusco at moderate activity to reduce altitude sickness risk; ascend slowly and avoid alcohol the night before.

High UV and sudden wind demand sunscreen, sunglasses, and a windproof shell even on cool mornings.
Sturdy hiking boots
Provide ankle support and traction on rocky, uneven trail surfaces.
Insulating layers and windproof shell
Temperature and wind change quickly above 4,000 m; layers let you manage sweat and cold.

Water bottle or hydration bladder (1–2 L)
Adequate hydration is critical at altitude and during the uphill sections.
summer
Trekking poles
Help with balance on steep or loose sections and reduce strain on knees during descent.
