A vast and mesmerizing expanse of shimmering salt, the Salar de Atacama in northern Chile stretches endlessly under the sun. This remarkable landscape is framed by steaming volcanoes and surreal crimson-hued formations, with its surface dotted by saline lagoons where graceful flamingos roam.

It’s an unforgettable and unique destination that ranks among Chile’s most iconic natural wonders.

Thanks to the wealth of tour operators based in nearby San Pedro de Atacama, this destination is one of the easiest to explore for travelers seeking a glimpse of Chile's extraordinary desert scenery.

How Did the Salar de Atacama Form?

Nestled between the Andes Mountains in the east and the Cordillera de Domeyko to the west, the Salar de Atacama came into existence through the actions of water and time. Streams carried mineral-rich waters from the surrounding peaks into the basin of the Atacama Desert. With no outlet for the water to escape, it evaporated under the relentless sun, leaving behind a striking, crusted surface of white and earthy brown salt.

Many liken its texture to coral, with a rugged, otherworldly appearance.

The Salar de Atacama is notable not only for its appearance but also for its size. Covering an area of approximately 1,200 square miles (3,000 km²), it is the third-largest salt flat on the planet, surpassed only by Salinas Grandes in Argentina and the vast Salar de Uyuni in Bolivia.

Visiting the Salar de Atacama

The Salar de Atacama is often included in tours departing from San Pedro de Atacama, the region’s primary hub. The area is home to several saline lagoons that sustain diverse wildlife, making them essential stops for any visit.

Here are some highlights to consider:

1. Laguna Chaxa

Located 35 miles (56 km) south of San Pedro, Laguna Chaxa is famed for its resident flamingos, including Andean, Chilean, and James species. These elegant birds thrive in the lake’s briny waters, feeding on tiny aquatic organisms. The lagoon is also a haven for photographers, offering scenes of flamingos wading gracefully against a backdrop of towering peaks and mirrored skies.

2. Laguna Cejar

Situated 12 miles (19 km) from San Pedro, Laguna Cejar is a deep emerald lagoon renowned for its buoyant waters. Its high salt concentration allows visitors to float effortlessly, making it a favorite spot for those seeking a unique swimming experience.

3. Laguna Tebenquiche

This sparkling lagoon, a short distance south of Laguna Cejar, is best visited during sunset. As the sun dips below the horizon, the surrounding salt crust takes on shades of pink and orange, creating an unforgettable visual display.

4. Ojos del Salar

Perhaps the most unusual feature of the area, the Ojos del Salar consists of two perfectly round pools of cold water. These striking lagoons, located on the road to Laguna Tebenquiche, are particularly refreshing during the warm desert summers, offering an opportunity to cool off.
