Tucked in Ecuador's Morona-Santiago Province, Aguas Termales Shuar Tsuer Entsa emerges in the Amazon rainforest at 38°C with a sulfurous character. Wild bathing in an open-air pool surrounded by jungle.
Insider tip — These springs carry the Shuar name Tsuer Entsa, meaning 'hot water' in the language of the indigenous Shuar people of the Ecuadorian Amazon, reflecting the deep cultural connection between this community and its geothermal landscape. The springs emerge on the Andean-Amazonian transition slope of Morona-Santiago province, where volcanic uplift meets the great eastern lowland basin. Surrounding terrain is dense Amazonian forest with extraordinary biodiversity, including countless orchid and bromeliad species. Reaching the site requires coordination with local Shuar guides, making this a genuine ecotourism and cultural encounter rather than a conventional spa visit.
