An early fog thins as the van winds up from Cusco and the Andes open into high grasslands. By the time you step out at Soraypampa (≈3,900 m) the air tastes thin and cold; the trail climbs steadily, the slopes turning from puna grass to rocky switchbacks. Ahead, Salkantay’s glaciated ridgeline watches over a bowl that holds Humantay’s impossible turquoise—the water so bright it seems to push light back into the sky.

Acclimatize before you go
Spend at least 48 hours in Cusco or similar altitude to reduce altitude sickness risk; ascend slowly and hydrate.
Layer for rapid weather shifts
Temperatures swing fast above 3,900 m—pack base, insulating, and waterproof layers to stay comfortable.
Protect against strong sun
UV is intense at high elevation—use SPF 50+, sunglasses, and a brimmed hat even on cloudy days.
Pace the uphill
Keep a steady, conversational pace and use trekking poles to reduce strain on knees on descent.
Layered clothing (base, fleece, shell)
Quick-dry base, warm mid-layer, and waterproof shell handle wide temperature and weather swings.
Sturdy hiking boots
Support and traction on rocky, sometimes muddy Andean trails reduces slip risk.
Water bottle or hydration bladder (2L+)
Hydration is critical at high altitude—carry enough water and sip regularly.
Trekking poles
Assist balance on steep, uneven terrain and reduce knee strain on descent.
