More ways to explore the area's outdoor wonders
A low diesel bus rounds a switchback and the valley opens: a pair of ice-blue lakes sits below serrated peaks, Huascarán and Huandoy towering like folded stone above. The guide steps down for a brisk walk on gravel paths that skirt Chinancocha (Llanganuco Lake) at about 3,850 m, the water reflecting snowbands and the flicker of wind-driven ripples.

History
The area is part of Huascarán National Park; the nearby town of Yungay was destroyed in the 1970 avalanche from Huascarán in 1970, and the Campo Santo memorial marks that event.
Conservation
Huascarán National Park protects fragile puna ecosystems and glaciers; stick to trails, pack out waste, and support local guides to benefit community stewardship.

Acclimatize first
Spend 24–48 hours in Huaraz before the tour to reduce altitude-related symptoms; hydrate and avoid heavy exertion on arrival.
Strong sun at altitude
Bring SPF 50+, sunglasses and a brimmed hat — UV is intense above 3,500 m and reflections off the water increase exposure.
Sturdy shoes for uneven ground
Trails around the lakes are short but rocky and sometimes wet; approach with trail shoes or light hiking boots.
Respect memorial sites
Yungay’s Campo Santo is a somber place; follow local guidance, keep voices low and avoid climbing monuments.
Layered jacket (fleece + windproof shell)
Mornings are cold and winds can cut quickly on exposed lake shores.
Sunscreen & wide-brim hat
High-elevation sun and reflected UV from the water make protection essential.
Sturdy trail shoes
Provides grip on gravel paths and wet shoreline rock.
1–2L water bottle and snacks
Hydration helps prevent altitude headaches and keeps energy up during the day.
