The Salar de Atacama is the largest salt flat in Chile, a huge, crusted basin that stretches south of San Pedro de Atacama beneath the Andes and the Cordillera Domeyko. At its heart, Laguna Chaxa is the best-known place to see flamingos, which feed in the shallow brackish water in the cool of the morning and evening. Three species, the Chilean, Andean and James's flamingos, can be found in the region, and the shapes of birds against a wide, pale lake with volcanoes behind them make for some of the most photogenic scenes in the Atacama. Walkways and viewing points guide visitors around the shore, keeping a respectful distance from the wildlife, and rangers or guides explain how the birds feed on tiny crustaceans and algae. Tours that include Toconao add a gentle cultural half-day to the wildlife stop. The village, set in an oasis about 38 km south of San Pedro, is known for its pale volcanic stone buildings, a detached bell tower beside its church, orchards and a small shaded canyon with a stream. Local artisans work with the stone and with wool, and it is a pleasant place for a short stroll and a coffee. Together, the salt flat, flamingos and village give a rounded picture of how life, water and salt interact in one of the driest places on Earth.
How it works
The outing is a half day by minibus, usually starting in the morning or the afternoon, when the flamingos are most active. Entry to the reserve is controlled and often included in the tour price, but check this when you book. Some itineraries add a stop at the Quebrada de Jerez, with its orchards, or tie the trip to a Ruta de los Salares day. The drive from San Pedro takes about an hour, and the walkways at Chaxa are short and flat.
What to expect
The salt crust is sharp and bright, so sunglasses, a hat and sunscreen are essential, and the wind can be strong. Keep your voice low and your movements slow near the water, since flamingos are easily disturbed, and never leave the paths. Binoculars or a zoom lens make a real difference. The lagoon is not a swimming spot, and the salt is not for walking on, but guides can point out the patterns formed by evaporation and the way the crust shifts in colour through the day.
Making the most of it
For the best light and bird activity, go early or late rather than at midday, and combine Chaxa with Toconao for a rewarding morning or afternoon. Bring cash for small purchases from artisans, and carry water. If you are visiting more than one salt flat or lagoon on your trip, space them out and mix them with a cultural stop like the Pukara de Quitor, so that each day feels different from the last.
The best views of the Licancabur and Lascar volcanoes across the salar come on clear days after cold nights.
