A pre-dawn van eases out of Cusco and the Andes press close—rock faces, distant glaciers and the slow light along the Apurímac valley. By Soraypampa you step out into thin, cold air; the trail climbs quickly through puna grass and rock, and the lake appears as a shock of blue above the switchbacks, a suspended pool fed by the glacier tongues of Nevado Humantay.

Acclimatize first
Spend 24–48 hours in Cusco or similar altitude before the hike to lower your risk of AMS; go slowly on the climb.
Hydrate and eat carbs
Drink frequently and eat light, high-energy snacks; dehydration worsens altitude symptoms.
Carry wind and rain protection
Weather shifts fast—bring a windbreaker and waterproof layer even on sunny mornings.
Use trekking poles
Poles reduce strain on knees on the descent and help maintain a steady pace uphill.
Waterproof windbreaker
Blocks wind and light rain at high elevations and retains core warmth.
Sturdy hiking boots
Support and traction on rocky, sometimes muddy trails up to 4,200 m.
Insulating layer & hat
Temperatures drop quickly at the lake; a warm mid-layer and hat are useful.
1–2 L water reservoir
Hydration is essential at altitude—bring more than you think you’ll need.
