Aguas Termales

On the high altiplano near Uyuni in Bolivia's Potosí department, these natural hot springs emerge in one of South America's most austere landscapes — the vast salt flats region where geothermal activity beneath the Andes forces sulfurous waters to the surface. The contrast between the raw, mineral-scented terrain and the steaming pools is utterly striking.

The water surfaces at 40 °C, carrying a distinct sulfurous character underscored by a mildly acidic pH of 6.5. Bathers feel the immediate warmth of the spring spread across the skin, while the sulphurous aroma — a hallmark of deep volcanic origin — marks this as a genuinely wild geothermal encounter. An unforgettable stop for those crossing the Bolivian southwest.
