Tucked within a secluded clay basin in the Cordillera de la Sal, the Hidden Lagoons of Baltinache (Lagunas Escondidas de Baltinache) comprise seven natural circular pools filled with vivid turquoise water set against a stark, blinding white crust of pure mineral salt.
Due to extraordinary salt saturation levels exceeding 30 percent, the water density is so high that swimmers experience a effortless flotation effect similar to that of the Dead Sea, floating buoyant on the surface without the need to tread water.

TRAILHEAD AND PLANNING LOGISTICS
The lagoons are situated roughly 45 kilometers southwest of San Pedro de Atacama. Access is via an unpaved desert dirt road that branches off the main route to Calama. While accessible with two wheel drive vehicles driven carefully, high clearance vehicles provide a smoother ride over the washboard gravel sections.
The site is managed by the local indigenous community of Coyo, featuring a visitor reception area with clean freshwater showers, which are essential for washing off salt crust after swimming. Entrance tickets are paid at the gate.
THE ROUTE AND TRAIL REPORT
Walking the Seven Lagoons: A marked pedestrian path made of compacted salt and gravel connects the seven natural lagoons. The circular pools vary in hue from deep cobalt to bright aquamarine, each surrounded by crystalline salt rims sculpted into delicate mineral terraces.
The Flotation Experience: To safeguard the delicate microbial ecosystems of the intermediate pools, bathing is permitted exclusively in the first and the seventh lagoons. Slipping into the mineral rich water, the body immediately bobs to the surface like a cork. Floating completely relaxed under the desert sun while looking out across the barren white landscape is an unforgettable sensation.
PRACTICAL TIPS AND ESSENTIALS
Freshwater Rinsing: Make use of the freshwater showers at the entrance immediately after swimming. As the brine evaporates in the dry desert air, it leaves a tight, itchy layer of white salt on the skin.
Eye Safety: Never splash or dive into the water. Due to the high salinity, even a single drop in the eyes causes intense stinging.
Footwear: The crystallized salt along the pool edges is sharp and abrasive. Wearing water sandals or flip flops to the pool edge is highly recommended.
