Laguna del Diamante

Laguna del Diamante is a high-altitude lake nestled within a volcanic caldera at 4,600 meters in Catamarca Province. The water displays extremely high alkalinity and salt concentration, creating conditions unlike typical lakes.

The lake formed within a volcanic depression and only recently became the focus of intensive scientific study. The discovery of flamingo colonies in 2010 revealed that life can thrive under extremely harsh conditions.

The lake holds spiritual significance for local communities and attracts researchers studying extreme life forms in harsh environments. Visitors can observe flamingos that have adapted to these conditions and shape the character of the landscape.

Access requires preparation for high altitude, as low oxygen levels can cause headaches and breathing difficulties. Visitors should allow time for acclimatization and bring warm clothing, as temperatures drop quickly at this elevation.

The water contains arsenic at concentrations 20,000 times above safety standards, yet specialized microorganisms thrive here and serve as food for flamingos. These extremophile organisms may resemble early life forms that emerged on Earth under similarly harsh conditions.
