Azufreras de Pelehue

Azufreras de Pelehue, or the Pelehue Sulfur Springs, is a natural sulfurous spring site in the Maule Region of southern Chile, where volcanic sulfur activity associated with the Chilean Andes drives sulfurous gases and heated mineral waters to the surface in a dramatic display characteristic of the country's active volcanic geology. The springs are named for their sulfur content — azufre in Spanish — which gives the waters and surrounding terrain their distinctive yellow mineral deposits and pungent volcanic character, creating a visually striking landscape where geothermal activity is visible in its most raw and elemental form. Visitors to Azufreras de Pelehue can bathe in the naturally heated sulfurous mineral waters and observe the active volcanic features of this remarkable geothermal site, located in the foothills of the Chilean Andes amid native forest and river valleys.
