Among the surreal landscapes of the Atacama Desert, where salt flats shimmer under an endless sky, Laguna Cejar stands as one of Chile’s most otherworldly natural wonders. Located about 20 kilometers south of San Pedro de Atacama, this spectacular turquoise lagoon is famous for its extremely high salt concentration, allowing visitors to float effortlessly on its surface — an experience often compared to that of the Dead Sea.
Surrounded by the vast Salar de Atacama, snow-capped Andean volcanoes, and dazzling white salt crystals, Laguna Cejar is one of the desert’s most photogenic sites. The destination attracts adventurers, photographers, and wellness travelers seeking an ethereal experience amid one of Earth’s driest places. Its tranquil environment, unique biology, and dreamlike visuals make it an unmissable stop during any trip to northern Chile.
History of Laguna Cejar
Laguna Cejar lies within the Salar de Atacama, Chile’s largest salt flat, which spans over 3,000 square kilometers. The area was formed millions of years ago through tectonic activity that trapped saline water at high altitude, leading to massive salt deposits over time. These shimmering crusts of sodium chloride, calcium, and magnesium are part of a complex ecosystem that sustains rare flora and fauna, including Andean and Chilean flamingos.
The lagoon’s name derives from the indigenous Atacameño communities who have inhabited the region for thousands of years. Historically, the area served both as a ceremonial site and as a refuge for wildlife. Today, local communities manage the area, limiting visitor numbers and protecting the delicate ecosystem from environmental impact.
Attractions at Laguna Cejar
- Floating in the Hypersaline Waters: The main draw of Laguna Cejar is its crystalline, salty waters. With a salt content more than seven times higher than seawater, visitors can float without any effort at all. This buoyancy creates a rare sensation of suspension amidst a landscape that feels completely unearthly.
- Striking Salt Formations: The lagoon’s perimeter gleams with white salt crystals, which change hue throughout the day — from iridescent white in midday sun to soft amber at sunset. Photographers flock to capture these reflections framed by distant volcanoes.
- Flamingo and Wildlife Viewing: Although swimming is restricted to certain sections, other parts of the lagoon remain untouched, providing nesting grounds for Andean and Chilean flamingos, as well as vicuñas and desert foxes. Early mornings and late afternoons are the best times to observe this wildlife.
- The Three Lagoons System: Laguna Cejar is part of a trio of connected saline lagoons that include Laguna Piedra (open for swimming) and Laguna Baltinache, known for their blue coloration and mirror-like reflections. The contrast between turquoise waters and stark salt plains makes for sensational landscape imagery.
- Panoramic Views of the Andes: From the shore, travelers can enjoy sweeping views of the Licancabur Volcano (5,920 m) and Lascar Volcano, which frame the desert horizon in shades of violet and gold during sunset.
