Introduction to the Laguna de los Pozuelos Natural Monument

Laguna de los Pozuelos Natural Monument

Geographical Location

Located in the Province of Jujuy, between the towns of Rinconada, Lagunillas, Yoscaba, Cieneguillas, and Pozuelos, this Natural Monument is an Internationally Important Wetland. It covers an area of over 200 square kilometers, spanning 16,000 hectares, making it one of the largest salt lakes in Argentina.

History and Recognition as a Natural Monument

Recognized as a Natural Monument in 1981, the area has served as a sanctuary for diverse bird species and local flora. The main objective of this recognition is the preservation of its rich biodiversity and the natural environment.

Through Decree Law No. 3749/1980, enacted and promulgated on December 29, 1980, the province of Jujuy transferred to the National State the jurisdiction, eminent domain, and ownership of certain lands encompassing the Laguna de los Pozuelos and its immediate surroundings. The purpose of this transfer was to incorporate this area into the National System of Protected Areas, thus acknowledging its natural value and the need for its preservation.

On January 28, 1981, through Resolution 997/1980, the National Parks Administration (APN) accepted the donation and submitted to the national Executive Power the proposal to create, by law, the Laguna de los Pozuelos Natural Monument. Although no specific law was enacted in this regard, the APN has been in charge of the administration and protection of the area since then, ensuring the conservation of its rich biodiversity.

On December 18, 1981, the government of Jujuy and the National Parks Administration signed a cooperation agreement with the purpose of evaluating the feasibility of establishing a national reserve, focused primarily on the preservation of vicuñas, a flagship species of the region.

Resolution No. 126/2011, issued on May 19, 2011, by the National Parks Administration, established that the Laguna de los Pozuelos Natural Monument would be classified, for administrative purposes, in the category of protected areas of complexity III. Consequently, a superintendent was appointed as the highest authority, overseeing the management of four departments: Administration, Infrastructure and Maintenance, National Park Rangers, and Conservation and Public Use. Additionally, there is a division responsible for Dispatch and Receipt of Correspondence and Notifications.

The superintendent’s headquarters are located in the town of Abra Pampa, from where the direction and coordination of activities related to the administration and conservation of the natural monument are carried out.

Climate in the Region

Laguna de los Pozuelos is characterized by a high-altitude arid climate, with extreme temperature fluctuations. Average temperatures range from 8°C in winter, with lows that can reach up to -30°C, to 16°C in summer, with highs exceeding 30°C. This temperature range demonstrates the marked difference between the seasons, with cold winters and warm summers.

The climate is also characterized by scarce rainfall, with approximately 200 mm of annual precipitation. Most of this rainfall occurs during the summer months, between December and March. During the cold months, experiencing strong frosts and sporadic snowfalls is common.

Best Times to Visit

The recommended season to visit the lagoon is in March and April, after the rainy season. During this period, thousands of flamingos paint the lagoon a beautiful pink color, providing a breathtaking spectacle. However, it’s important to note that summer rains, though scarce, can hinder access to the lagoon due to road closures.

Prices and Fees

Access to the Laguna de los Pozuelos Natural Monument is free of charge.

Ecological Importance and Biodiversity


Located in the Puna ecoregion, an expansive plain at an altitude of approximately 4,000 meters above sea level, this natural monument is a brackish body of water that undergoes constant changes in its boundaries, determined by the contribution of rivers from the thaw of the Andean mountains and surrounding hills.

The ecosystem of Laguna de los Pozuelos is unique due to its location in the Puna, characterized by high altitude and extreme climatic conditions. The lagoon is mainly fed by meltwater, which contributes to its brackish nature. This combination of factors creates a fragile yet dynamic environment, with biodiversity adapted to the highland conditions, including migratory and endemic bird species.


It harbors a unique diversity of fauna, including endemic birds, mammals, and reptiles. The fauna of the area is a true display of adaptation to the highland ecosystem.

The fauna in Laguna de los Pozuelos is extraordinary, hosting a variety of birds that are exclusive to the Puna region. Prominent species include the Andean avocet, Puna plover, and giant coot. These birds are endemic and have adapted to the specific conditions of this ecosystem.

During the summer, the lagoon welcomes migratory birds from the northern hemisphere, such as the Wilson’s phalarope and the red knot. These birds take advantage of the favorable environment of the lagoon to feed and rest during their migratory journey.

However, it’s the flamingos that steal the limelight in this body of water. More than 30,000 individuals of the three flamingo species found in Argentina—the Chilean flamingo, Andean flamingo, and James’s flamingo—have been counted. These majestic birds are a true emblem of the lagoon, and their presence is awe-inspiring.

The importance as a habitat for birds is so significant that in 1992, it was declared a Ramsar Site. This designation is given to wetlands of international importance and is recognition of the concentration and diversity of birds inhabiting this protected area.

The presence and abundance of birds testify to the richness and vitality of this aquatic ecosystem, making it a destination of interest for both bird enthusiasts and those who appreciate the beauty of wildlife.


A marked contrast can be observed between the rocky soils and the vegetation that covers them. The flora in this area adapts to the extreme conditions of the Puna ecosystem, where high altitude and aridity are determining factors.

The predominant vegetation consists of shrubs and yareta, which adapt to the rocky soils and water scarcity. These plants have a low and compact growth form, allowing them to withstand the strong winds and low temperatures characteristic of the region.

Despite the apparent aridity of the landscape, Laguna de los Pozuelos is an important habitat for a great diversity of birds. These birds find the lagoon to be a site for feeding and nesting. The presence of water and the abundance of small aquatic organisms provide a vital resource for avifauna, attracting numerous species.

It’s fascinating to observe how the sparse vegetation contrasts with the richness and variety of birds that inhabit and utilize the lagoon. This dynamic ecosystem demonstrates the adaptability of flora and its importance as a refuge for wildlife.

Flamingos as Emblematic Species

In the Laguna de los Pozuelos, three species of flamingos can be found: the Chilean flamingo, the Andean flamingo, and the James’s flamingo. The latter two species are mainly residents of the Puna region.

The James’s flamingo (Phoenicoparrus jamesi) is particularly emblematic. It’s the smallest species of flamingo that inhabits the lagoon. It’s characterized by its yellow beak with a black tip and its reddish-colored legs. These features are useful for distinguishing it from the other flamingo species present in the area. The James’s flamingo primarily feeds on small crustaceans, which it filters from the water using its distinctive beak.

Unfortunately, the James’s flamingo is considered a threatened species. This highlights the importance of conserving and protecting its habitat, as it is a vital refuge for this species and other waterfowl.
