The morning light in the Callejón de Huaylas hits hard and clear, turning moraine and moraine-fed water into a palette of blues. On day one, travelers step from the minivan onto the shore of Parón Lake and face the hulking silhouettes of Pirámide de Garcilaso and Artesonraju; the water dares you to stop and look, to slow a breath and take a photograph.

Acclimatize in Huaraz
Spend 24–48 hours in Huaraz at ~3,100 m before the high passes to reduce altitude sickness risk.
Hydration is non-negotiable
Carry at least 2–3 liters and sip regularly—altitude and dry mountain air increase fluid loss.
Footwear and traction
Use stiff-soled hiking boots with good traction for scree, muddy trails and potential snow patches.
Start early on Lake 69 day
Begin pre-dawn to avoid afternoon weather changes and to secure quiet viewpoints at the lake.
Sturdy hiking boots
Support and traction for steep approaches, scree and uneven trails.
Insulated jacket (down or synthetic)
High-altitude mornings and evenings are cold; temperatures can drop below freezing.
winter
Sun protection (hat, sunglasses, SPF 50)
Strong UV at altitude requires broad protection even on cool days.
summer
Hydration system (2–3 L)
Continuous sipping prevents altitude-related dehydration and headaches.
