Laguna 69 – Turquoise Glacial Lagoon in the Cordillera Blanca

Laguna 69 at a Glance

Laguna 69 is located in the Quebrada Demanda in the Cordillera Blanca. The regional tourism administration lists it at an altitude of 4,604 meters. From Yungay, the destination is about 58 kilometers away; for many travelers, the day trip already begins in Huaraz.

The water is primarily fed by meltwater from Chacraraju. The intense turquoise-blue color contrasts sharply with rock faces, snowfields, and high-Andean vegetation. From the lagoon area, Chacraraju, Pisco, and Yanapaqcha, among others, are part of the mountain panorama.

The lagoon is part of the Huascarán National Park. Its water surface is stated to be approximately 97,800 square meters, with a maximum depth of 58 meters. The plain name refers to the numbering of the lakes in the protected area.

Why Laguna 69 is Special

Laguna 69 is not only remarkable for its water color. On a single day's route, the valley floor, waterfalls, Queñual stands, open Puna, and glaciated mountain flanks alternate. This means the hike displays several typical Cordillera Blanca landscapes over a relatively short distance.

The lagoon also represents the sensitive high-mountain ecosystems of the Peruvian Andes. Meltwater, glaciers, and high-Andean wetlands react particularly sensitively to climate change and increasing tourism.

The Route to Laguna 69

Cebollapampa

The classic trek begins at Cebollapampa. From here, the path initially leads relatively moderately through the valley before longer ascents begin. Even at the start, high mountain flanks and watercourses shape the landscape.

Quebrada Demanda

The path follows the Quebrada Demanda. Waterfalls, wetlands, and Queñual stands accompany the ascent. Several open sections offer views of the glaciated peaks of the Cordillera Blanca.

Final Ascent to the Lagoon

The final section is steeper and particularly demanding due to the increasing altitude. Those who walk steadily and plan enough breaks will eventually reach the basin of Laguna 69 at 4,604 meters.

Landscape, Plants, and Wildlife

The hike leads through high-Andean vegetation zones of the Puna. Queñual trees are among the most striking woody plants, while low grasses and other cold-adapted plants dominate the open areas. Sensitive wetlands and vegetation cushions should not be stepped on.

Vizcachas can be observed on the route. Deer and foxes also occur in the protected area. Wild animals should neither be fed nor harassed for photos.

Admission, Access, and Visit

An entrance ticket for the Huascarán National Park is required for the visit. PROMPERÚ states S/ 15 for national adults, S/ 12 for local adults or national children aged 5 to 16, S/ 5 for local children, and S/ 30 for foreign visitors for a day ticket. As tariffs can be changed, the current price should be checked before traveling.

Swimming in Laguna 69 is prohibited. This rule protects the sensitive high-mountain waters and applies regardless of weather or visitor numbers.

Opening Hours and Season

Laguna 69 is generally visited year-round. For hikes in the Cordillera Blanca, the drier months from April to October are considered more predictable. During the rainy season, clouds, precipitation, and slippery trail sections may occur more frequently.

An early start is advisable because the entire tour takes several hours and the weather in the high mountains can change rapidly in the afternoon. Warm and waterproof clothing should be in the backpack even with a sunny start.

Current Situation

Since May 2026, improvement works on the tourist infrastructure of Laguna 69 have been underway. The state project includes, among other things, parking, camping area, viewpoints, trail repairs, rest areas, sanitary facilities, and signage. Approximately S/ 3.18 million and 180 calendar days of construction time were planned. Potential local restrictions should be checked before visiting.

How Demanding is the Hike?

The day hike is often classified as moderately difficult, but the altitude significantly alters the exertion. The destination is at 4,604 meters. Even trained visitors can clearly feel the lower oxygen content.

Prior acclimatization in Huaraz or at a comparable altitude is advisable. Headaches, nausea, dizziness, or unusual exhaustion should be taken seriously. If symptoms are severe, further ascent is not recommended.
