Laguna Hedionda (Sud Lípez)

Laguna Hedionda is a high-altitude lake located in the Sud Lípez province of the Potosí Department in southwestern Bolivia. Its name, meaning "Stinking Lagoon" in Spanish, refers to the sulfurous odors emanating from the lake's waters, which are rich in minerals and algae.

The lake is part of the Eduardo Avaroa Andean Fauna National Reserve, a protected area known for its stunning Andean landscapes, diverse wildlife, and geothermal activity. Laguna Hedionda is a popular destination for tourists visiting the reserve, particularly for birdwatching. The lake's shallow, mineral-rich waters support large populations of flamingos, including the Andean flamingo, James's flamingo, and Chilean flamingo. Other bird species commonly observed around the lake include Andean geese, vicuñas, and various types of ducks and shorebirds.

The landscape surrounding Laguna Hedionda is characterized by barren plains, volcanic peaks, and hot springs. The elevation of the lake is approximately 4,100 meters (13,450 feet) above sea level, resulting in a harsh climate with cold temperatures and strong winds. Due to the altitude and remote location, the air is thin and dry.

The lake's high mineral content contributes to its unique colors, which can vary depending on the time of year and the concentration of different minerals. The waters are typically a mix of greens, yellows, and browns. Despite the extreme conditions, Laguna Hedionda supports a thriving ecosystem and is an important habitat for numerous bird species.
