A cool, thin air greets hikers before dawn as the minivan climbs out of Cusco and into the steep, green folds of the Apurímac valley. By the time you reach Soraypampa a wind-scoured plain opens, and the trail steals uphill toward a bright turquoise bowl pinned beneath the glacier-streaked face of Humantay Mountain.

History
The Salkantay massif has long been part of Andean ritual geography; local Quechua communities hold the mountains as sacred apus and maintain traditional farming practices in nearby valleys.
Conservation
The high‑altitude wetlands and glacial systems are sensitive to climate change; stick to trails, pack out waste and support local operators who use sustainable transport and fair labor.

Acclimatize first
Spend 1–2 days in Cusco before the hike to reduce altitude effects; take it slow on the ascent and sip small amounts of water frequently.
Layer for changeable weather
Bring a warm insulating layer plus a waterproof shell—the summit breeze can feel frigid even on a sunny day.
Use trekking poles
Poles reduce strain on knees during the steep final ascent and descent and help with balance on loose scree.
Protect from sun
High‑altitude UV is strong—wear a broad‑brim hat, sunglasses and SPF 30+ sunscreen.
Sturdy hiking boots
Good ankle support and tread for rocky, uneven trail sections.
Insulating jacket (down or synthetic)
Warmth for the summit and windy conditions at 4,200 m.
Water reservoir or 1.5 L water bottle
Hydration is critical at altitude; sip small amounts frequently.
Sun protection (hat, sunglasses, sunscreen)
Protects against strong UV and glare off rock and water.
