Terma Sachayacu is a sulfurous hot spring in the Amazon foothills of South America, where the Quechua name Sachayacu — meaning 'jungle water' or 'forest river' — evokes the lush tropical forest setting of this geothermal site at the interface between the Andes and the Amazon basin. The spring emerges from the volcanic and tectonic geology of the Andean foothills where the mountains descend toward the rainforest, producing naturally heated sulfurous mineral waters in a landscape of extraordinary biodiversity. Visitors experience the rare combination of Andean geothermal bathing and Amazonian rainforest immersion, soaking in naturally heated sulfurous waters while surrounded by the sights and sounds of one of the world's most biodiverse ecosystems.

Insider tip — Terma Sachayacu 666 sits near Papallacta on the eastern slopes of the Andes, where sulfurous springs emerge at the edge of the Amazon headwaters region. The Napo Province setting combines Andean volcanic geology with cloud forest biodiversity, creating a uniquely biodiverse backdrop for bathing. High-altitude sulfurous springs here are among Ecuador's most pristine, fed by glacial meltwater mixing with geothermal vents. Early morning visits let you soak while condors occasionally drift overhead on thermal updrafts.
