A 12-day high-altitude circuit in Peru’s Cordillera Blanca that links Laguna 69, multiple 4,400–4,850 m passes and the base of Alpamayo—plus a community donation day that brings aid directly to local villages. Expect long days, alpine camps and dramatic glacial scenery.

Dawn in the Callejón de Huaylas smells of wood smoke and coffee; the bus grinds north from Huaraz and the peaks of the Cordillera Blanca begin to rise like a row of weathered teeth. On day two you step at 4,000 m from Cebollapampa and climb toward Laguna 69 — a quick, steep slice of alpine blue that wakes your legs and tests your lungs. Over the next ten days the route threads high passes (up to about 4,850 m), remote valleys and campsites under the north face of Alpamayo.

This circuit runs through landscapes long managed by Quechua pastoralists; many trails follow ancestral routes between seasonal grazing areas.
Conservation
The Cordillera Blanca is experiencing rapid glacial retreat—practice Leave No Trace, pack out waste and minimize campfire use to protect fragile high‑altitude ecosystems.

Acclimatize before pushing hard
Spend at least one full day at Huaraz and take the included acclimatizing village visit seriously—altitude, not distance, causes most problems.
Hydrate and manage electrolytes
Carry a 2–3L capacity and sip regularly; electrolyte tablets help prevent headaches and cramping above 4,000 m.
Strong boots and poles
Rugged, broken trail and steep descents demand stiff-soled boots and trekking poles to reduce ankle strain.
Plan for sun and storm
High UV and sudden storms mean sunglasses, sunscreen and a lightweight waterproof shell are non-negotiable.
Sturdy waterproof trekking boots
Support and grip for rocky trails and long descents.
3-season sleeping bag (-10°C comfort)
Cold nights at camps around 3,800–4,300 m require a warm bag.
Layered clothing system (base, insulating, waterproof shell)
Quick temperature swings and wind at high passes make layers essential.
Trekking poles
Help protect knees on long descents and provide balance on scree and snow patches.
