Travelers leave Cusco before dawn for a long day of road and trail to a glacier-fed turquoise lake beneath Salkantay. The Humantay lagoon is short but steep to reach; altitude planning and layered gear make the difference between suffering and savoring the views.
More ways to explore the area's outdoor wonders
A pre-dawn van leaves Cusco while the city’s lights still wink; the road climbs into the high valleys and the air thins with each kilometer. By the time you step onto the dusty Soraypampa trailhead the world has shifted—tall, wind-scoured ridges cut the sky and distant snowfields glint. The Humantay lagoon appears like a polished shard of turquoise framed by the white shoulders of Humantay and the Salkantay massif.

Acclimatize in Cusco first
Spend at least 48 hours in Cusco or a similar altitude before the trek to reduce the risk of altitude sickness.
Hydrate and protect from sun
Bring 2–3 liters of water and high-SPF sunscreen—UV is strong above 4,000 m and dehydration accelerates altitude effects.
Use trekking poles for the ascent
Poles reduce strain on knees and help maintain a steady rhythm on steep, rocky pitches—especially when the trail is wet or snowy.
Know the altitude warning signs
If you get severe headache, nausea, dizziness or shortness of breath, descend and seek help—oxygen and medical support are limited on the trail.
Sturdy hiking boots
Support and traction on rocky, uneven high‑altitude trails matter more than light sneakers.
Insulating shell (windproof/waterproof)
Mornings and afternoons are cold and windy; a packable shell keeps you comfortable during stops.
Trekking poles
Poles aid balance and reduce effort on the steep ascent and descent.
Sunglasses and sunscreen
High UV at 4,000+ m can cause sunburn and snow glare—even on cloudy days.
