🇵🇪 Peru · The Highlands and the Andes
Laguna 69 is the star hike of the Cordillera Blanca and one of the most famous postcards of Andean Peru: a lake of electric turquoise, wedged into an amphitheater of mountains, with a meltwater waterfall dropping from the glaciers and the imposing Chacraraju peak looming above. It lies inside the Parque Nacional Huascarán, at about 4,600 meters, and its name -so unpoetic- comes from an old numbering of lakes in the park that never got a traditional name.
Getting there is not free of effort: the route is about 15 km round trip and, above all, it is done at real altitude, with a climb you feel. Most people do it as a full-day trip from Huaraz: leaving before dawn (around 5 in the morning), three to four hours of transport to the trailhead, the climb, time at the lake and the return. It is a long day, but the payoff -that incredible blue ringed by snow- justifies every step.
The key here is acclimatization. Doing Laguna 69 right after arriving in Huaraz is a bad idea: the sensible thing is to spend a day or two beforehand on gentler walks so your body gets used to the altitude. Bring layers, warm clothes, plenty of water, snacks, strong sunscreen, a hat and sunglasses. Mountain weather changes fast: you can have blazing sun and, a while later, freezing wind or a little snow.
Laguna 69 is a lake of glacial origin, fed by meltwater from the snowcaps of the Cordillera Blanca, inside the Parque Nacional Huascarán (created in 1975 and recognized by UNESCO). Its curious name comes from an old numbering used to catalogue the many lakes in the park that had no name of their own. This whole basin is part of the same glacial massif whose collapse, in 1970, caused the Yungay disaster. More context on the history page for Huaraz and Huascarán.

Origins, formation and what the sources say.
Few names for a tourist destination are as prosaic as Laguna 69. And yet behind that figure there is a simple, curious story. When the Parque Nacional Huascarán, in the Cordillera Blanca, was mapped out and studied, the surveyors catalogued dozens upon dozens of glacial lakes. Many had traditional names in Quechua or Spanish; others, more remote or not used day to day by the communities, had no name of their own. To inventory them, they were simply assigned a number. One of them got 69, and it stuck.
Far from taking away its charm, that practical name contrasts with the almost unreal beauty of the place and has become part of its appeal. Laguna 69 sits at about 4,600 meters, in an amphitheater of rock and ice, fed by meltwater from the glaciers around it. The intense turquoise of its water comes from the extremely fine mineral particles carried down by the melting ice, which stay in suspension and scatter the light.
It is, then, a lake of glacial origin, relatively young in geological terms, a direct child of the snowcaps of the Cordillera Blanca. Its existence depends on those glaciers, today threatened by the retreat brought on by climate change, a process visible across the whole region.
Laguna 69 is not an isolated spot but one more jewel inside the Parque Nacional Huascarán, created in 1975 to protect almost the whole Cordillera Blanca. This park guards the highest tropical mountain range in the world, with dozens of peaks above 6,000 meters -headed by Huascarán, at 6,768 m the highest mountain in Peru-, along with glaciers, lakes, queñual woods and wildlife that includes the Andean condor, the vizcacha and the taruca deer.
In 1985 UNESCO inscribed the Parque Nacional Huascarán on the World Heritage list, in recognition of its exceptional natural value. The walk to Laguna 69 crosses part of these landscapes: it passes close to the Llanganuco lakes, crosses pampas and queñual woods -one of the highest-growing trees on the planet- and ends at the foot of peaks such as Chacraraju.
Visiting the lake is therefore a way of looking in on a fragile, protected high-mountain ecosystem. That is why there is an admission fee for the park, why visitors are asked to leave no rubbish and not to stray from the trails, and why the emphasis is on respecting both the nature and the communities who have lived in the Callejón de Huaylas since ancient times.
Long before Laguna 69 had a number or a tourist sign, the Cordillera Blanca and the Callejón de Huaylas were already inhabited. Pre-Inca cultures such as the Recuay (which flourished between the 2nd and 7th centuries AD in what is now Áncash) left pottery, tombs and stone sculptures in these valleys, and later the region was incorporated into the Tahuantinsuyo by the Incas, who valued the snowcapped mountains as apus, or tutelary deities.
For the Andean communities, the peaks of the Cordillera Blanca -Huascarán, Huandoy, Chacraraju, Alpamayo- were not just geographical features but sacred beings that regulated the water, the weather and the fertility of the fields. The glacial lakes, fed by those same peaks, were part of that same system of belief: respect was paid to them and, in some cases, offerings, as still happens today in pago a la tierra ceremonies at different points in the Peruvian Andes.
That ancestral relationship with the mountain is still alive in the farming communities of the Llanganuco valley and around it, who go on grazing livestock on the high punas and who are, in a way, the true custodians of the landscape that hikers walk through today on their way to Laguna 69.
No account of the Cordillera Blanca can skip over 31 May 1970, the day a magnitude 7.9 earthquake with its epicenter off the coast of Áncash broke away an enormous mass of ice and rock from the north face of Huascarán. That avalanche, reckoned in millions of cubic meters, came down on the town of Yungay -barely a few kilometers from the starting point for Laguna 69 and the Llanganuco lakes- and buried it almost completely in a matter of minutes, causing tens of thousands of deaths.
The Yungay disaster is, to this day, one of the deadliest natural disasters in the history of Latin America, and it changed the region's relationship with its own glaciers for good: beautiful and imposing, but also capable of extreme destructive power. The old site of Yungay is kept as a burial ground and memorial, visited by those traveling the Callejón de Huaylas.
That episode also drove greater control and monitoring of the glacial lakes in the area, many of which -including Laguna 69 itself, at its own scale- are watched for the risk of outburst floods or avalanches (so-called 'GLOFs', for glacial lake outburst floods) caused by the accelerated retreat of the glaciers due to climate change. Walking today toward Laguna 69 means, in a way, crossing a landscape that is still alive, still changing and not free of natural hazards.
The modern exploration of the Cordillera Blanca began at the end of the 19th century and intensified in the 20th with expeditions of European mountaineers, above all Austrians and Germans, drawn by technical peaks such as Alpamayo (dubbed by some 'the most beautiful mountain in the world') or Chacraraju, the summit that crowns the very amphitheater of Laguna 69. Huaraz, then a provincial town, gradually established itself as the logistical base for these expeditions.
The 1970 earthquake marked a turning point for tourism too: Huaraz had to be rebuilt almost completely, and in the following decades the town redirected a good part of its economy toward trekking and mountaineering, backed by the creation and consolidation of the Parque Nacional Huascarán. For a long time the best-known routes were the multi-day treks, such as Santa Cruz-Llanganuco or the Huayhuash circuit.
Laguna 69, on the other hand, remained for years a relatively secondary outing next to those long treks, known above all to experienced hikers and local agencies. Its takeoff as one of the most photographed destinations in Peru is recent, tied to the rise of social media: from the 2010s, and more strongly in the years 2015-2020, thousands of photographs of the impossible turquoise of its water -compared again and again with Laguna Humantay in Cusco or with landscapes in Patagonia- circulated on Instagram and other platforms, sending its popularity soaring among travelers from all over the world.
Today Laguna 69, with Huaraz as its base, is one of the pillars of adventure and nature tourism in Peru, with dozens of agencies offering the full-day tour and a steady flow of visitors in the dry season. That growth brought economic benefits for Huaraz and the communities of the valley, but it also raised environmental management challenges: waste control, the carrying capacity of the trails and the need for every visitor to understand that they are walking through a high-mountain ecosystem as fragile as it is spectacular.
