Laguna Hedionda: A high-altitude paradise in Bolivia
Laguna Hedionda is one of the most breathtaking destinations on the Bolivian altiplano, famous for its intense turquoise color, the large number of Andean flamingos that inhabit it, and its surrounding volcanic landscapes. It is located at an approximate altitude of 4,121 meters above sea level, in the southwestern region of Potosí, within the Eduardo Avaroa Andean Fauna National Reserve, one of Bolivia’s most important protected areas.
Despite its name—which comes from the strong sulfurous odor due to its high mineral concentration—Laguna Hedionda is a natural spectacle that combines wildlife, geology, and surreal landscapes.

🌋Why is it called Laguna Hedionda?
The name “Hedionda” comes from the sulfurous smell emanating from its waters, caused by the high concentration of minerals and sulfur compounds. Although the smell can be faintly detected, it is not unpleasant for most visitors and is part of the natural experience of the place.
This mineral content is precisely what fosters the life of microorganisms, the base of the flamingo food chain.
