Laguna Colorada
Potosí
Laguna Colorada, or Red Lagoon, is a shallow hypersaline lake located in the Eduardo Avaroa Andean Fauna National Reserve in Bolivia at an altitude of approximately 4,278 meters. Its vivid crimson waters are caused by red sediments combined with pigmented algae, primarily Dunaliella salina, adapted to high salinity. The lake's color intensity varies with algae concentration, sunlight, and temperature, ranging from soft pink to deep red. White borax islands scattered across the lagoon create a striking contrast with the red water. Ecologically, Laguna Colorada is a critical habitat and breeding ground for several flamingo species, including James's flamingos, Andean flamingos, and Chilean flamingos, which feed on the abundant plankton that also colors their feathers pink. The surrounding arid high-altitude ecosystem supports other adapted wildlife such as the Andean mountain cat, Andean fox, vicuñas, and llamas. The lagoon's water chemistry is rich in sodium chloride, borates, sulfates, and diatomite, with pH levels ranging from 5.3 to 9.0. Laguna Colorada is part of a Ramsar-designated wetland of international importance, highlighting its environmental significance and unique natural beauty.

Consejo: The best time to visit Laguna Colorada is during the dry season, from May to October, when the lake's red coloration is most intense. Visitors should consider booking guided tours in advance due to the remote location within the Eduardo Avaroa Reserve. While there is no need to purchase tickets for the lake itself, entrance fees to the reserve may apply. Bring sun protection and warm clothing due to the high elevation and variable weather conditions. Respect wildlife habitats and avoid disturbing flamingo breeding areas for the best ecological experience.

Historia
Laguna Colorada was designated a Ramsar Wetland of International Importance in 1990, recognizing its unique ecological value.
Originally named after its distinctive red waters, the protected area was expanded significantly in 2009 to include surrounding high Andean lakes and wetlands, reflecting growing conservation efforts.
The lake has long been a vital breeding site for flamingos and an important ecosystem within the Altiplano, adapting to extreme high-altitude conditions over centuries.
