Termas de Ralún is a naturally warm sulphurous thermal spring resort in the Ralún area near Cochamó, at the head of the Reloncaví fjord in the Los Lagos region of southern Chilean Patagonia. The springs emerge in a landscape of extraordinary beauty where the fjord's sheltered waters reflect the snow-capped peaks of the Andes and the dense temperate rainforest cascades to the water's edge. The thermal baths at Ralún offer visitors the rare pleasure of soaking in naturally warm mineral water at the meeting point of Chilean Andean mountains and Patagonian fjords — one of the most spectacular geothermal settings in the Southern Hemisphere.
Insider tip — Termas de Ralun overlooks the Reloncavi Estuary in Los Lagos Region, a fiord-like inlet ringed by snow-capped Andean volcanoes including Calbuco. The sulfurous springs here seep from volcanic deposits at the estuary's edge, creating pools with views across the water rarely matched elsewhere in Patagonian Chile. Sea kayakers often stop here as part of longer estuary expeditions.
