Llanganuco lagoons: turquoise paradise of Ancash

What are the Llanganuco lagoons?

The Llanganuco lagoons are a spectacular set of two natural bodies of water located in the Llanganuco valley, Yungay province, Ancash department. They are situated at an altitude of 3,850 meters above sea level and consist of the lagoons Chinancocha (female lagoon) and Orconcocha (male lagoon). They are the main attraction of Huascarán National Park and one of the most emblematic ecotourism destinations in Peru, globally recognized for their crystal-clear turquoise waters that reflect the imposing snow-capped peaks of the Cordillera Blanca.

What does Llanganuco mean?

The name “Llanganuco” comes from the Ancash Quechua language and means “greenish interior.” It is composed of the Quechua words “llanka” (jasper color) and “uku” (interior, bottom), referring to the characteristic greenish and turquoise reflection of the waters of these lagoons. The individual names also have Quechua meanings: Chinancocha means “female lagoon” (Chinan = female; cocha = lagoon) and Orconcocha means “male lagoon” (Orcon = male; cocha = lagoon).

Where are they located?

They are located in the Llanganuco valley, Yungay province, Ancash department, within Huascarán National Park. The lagoons are approximately 84 kilometers northeast of the city of Huaraz and 25 kilometers from the town of Yungay. They sit in a narrow glacial valley flanked by the most imposing mountain formations of the Cordillera Blanca: Huascarán (6,768 m), Huandoy (6,395 m), Pisco (5,760 m), Chacraraju (6,108 m), Yanapaccha, and Chopicalqui (6,395 m).

What are the characteristics of the lagoons?

Physical characteristics

They are two impressive glacial water bodies, each with distinctive features. Laguna Chinancocha (female lagoon): With a length of 1,450 meters, a width of 393 meters, and a maximum depth of 28 meters, it features intensely turquoise waters surrounded by queñual forests and reeds. Laguna Orconcocha (male lagoon): Located at a higher altitude (3,860 m), it has a length of 910 meters, a width of 368 meters, and approximately 7 meters of depth, with crystal-clear blue waters. Both lagoons are fed by the melting snow from the surrounding peaks, and their waters flow into the Ranrahirca River, a tributary of the Santa River.

Climate

It belongs to the puna ecological floor (high Andean), with tropical mountain climatic characteristics. The average temperature is 10°C, with daytime highs reaching 20°C and nighttime lows dropping to -5°C. The waters of the lagoons remain very cold throughout the year. There are two well-defined seasons: dry (May-September) with clear skies and little rainfall, and wet (October-April) with frequent precipitation, especially in March.

What fauna and flora can be observed?

Among the fauna, wild ducks, coots, Andean herons, mountain gulls, and occasionally Andean flamingos stand out. Around Laguna Chinancocha, it is common to see ducks approaching tourist boats. In the high areas, you can spot vicuñas, tarucas, and occasionally the spectacled bear. Laguna Orconcocha is home to numerous wild birds that can be aggressive, so navigation is restricted.

As for flora, queñual forests (Polylepis), a characteristic tree of the Andes that forms dense forests along the banks, are abundant. Reeds, alders, ichu (high Andean grass), and various medicinal and aromatic plants adapted to high altitudes can also be found. During the wet season, the landscape is enriched with wildflowers in vibrant colors that contrast with the intense blue of the waters.

What activities can be done?

Main activities

Boat rides: The most popular activity at Laguna Chinancocha, with boats available for 10-15 minute tours enjoying panoramic views of the snow-capped peaks.

Nature photography: Morning light conditions offer the best moments to capture the reflection of the snow-capped peaks in the turquoise waters, especially between 9:00 and 11:00 am.

Interpretive hiking: Short walks around Laguna Chinancocha on well-marked trails that allow you to appreciate local flora and capture different photographic perspectives.

Birdwatching: Especially during dawn and dusk when the activity of water birds is highest.

Horseback riding: Available in the Chinancocha area for scenic tours around the lagoon.

Trekking to María Josefa: For more adventurous visitors, a trail that connects to more challenging trekking routes to other destinations in the Cordillera Blanca.

Traditional ceremonies

It is common for local communities to perform Andean rituals such as offerings to Pachamama and ceremonies of gratitude to the Apus (mountain spirits). The lagoons hold deep spiritual significance for Andean communities, who consider them sacred places inhabited by mountain spirits. According to local tradition, there is a legend that tells of Huascarán and Huandoy as two lovers who turned into mountains, and their tears of sorrow formed the lagoons Chinancocha and Orconcocha.

What is the best time to visit?

The best time is between April and November, during the dry season, when the days are sunny and the ground conditions facilitate access. The months of June to August represent the high season with little to no rainfall and completely clear skies. During these months, the waters display their most intense turquoise color due to better sunlight. Mornings between 9:00 and 11:00 am offer the best conditions for photography, when the sun reflects directly on the lagoons, enhancing their colors.

What to bring for the visit?

Recommended equipment

Clothing: Warm layered clothing (temperatures can drop to -5°C), windbreaker jacket, comfortable footwear for short walks, hat and gloves for the morning chill.

Sun protection: High SPF sunscreen (UV radiation is intense at high altitude), sunglasses, hat or cap.

Supplies: Sufficient water and energy snacks, camera with extra battery (cold drains batteries quickly), cash for optional activities.

Medications: Remedies for altitude sickness, personal medications, basic first aid kit.
