You arrive before dawn, the van humming through puna grasslands as peaks darken into silhouette. By the time the convoy slows at the trailhead above Mollepata or Soraypampa, the air is thin and cold; the mountain seems to hold its breath. The hike climbs on a steep, rocky switchback toward a bowl of brilliant blue — Laguna Humantay — framed by the glacial shoulder of the Humantay massif.

Acclimatize First
Spend 24–48 hours in Cusco to reduce altitude sickness risk; move slowly on the ascent and carry coca tea if you use it.
Hydration & Snacks
Bring 1–2 liters of water and high-energy snacks; the sun and altitude dehydrate faster than you expect.
Sun & Wind Protection
At 4,200+ m UV is strong and winds can cut temperatures—use SPF, sunglasses, a sun hat, and a wind shell.
Consider a Horse or Cane
Horses can be rented for the steeper final section and canes/trekking poles help with balance on loose rock.
Sturdy hiking boots
Support and traction on steep, rocky switchbacks and uneven ground.
Insulating mid-layer and wind shell
Layering manages cold mornings and gusty winds near the lagoon.
Sun protection (hat, sunglasses, SPF)
High-altitude UV is intense year-round; protect skin and eyes.
Trekking poles or cane
Reduces strain on knees during ascent/descent and improves balance on scree.
