Termas de Río Blanco Los Lagos are volcanic thermal springs in the Los Lagos Region of southern Chile, situated near Puerto Montt — the gateway city to Chilean Patagonia — in a landscape defined by glaciated volcanoes, fjords, salmon farming, and Chiloé island culture. The calcium-rich waters here emerge from the volcanic geology of the Southern Andes and offer therapeutic soaking in pools surrounded by temperate rainforest and Andean mountain scenery typical of Chile's scenic Lake District. As part of the geothermally active southern volcanic zone stretching through Los Lagos and Los Ríos regions, these springs offer an authentic encounter with Chile's volcanic natural heritage in one of South America's most dramatically beautiful landscapes.
Insider tip — Termas de Río Blanco emerge along a glacial river valley in Chilean Patagonia's Los Lagos region, where calcium-rich waters at 39°C contrast strikingly with the ice-blue flow of the Andean meltwater river beside the pools. Araucaria monkey-puzzle trees and southern beech forest form the canopy overhead. The remoteness of the site — reachable only by unpaved track — means the pools are often shared with no more than a handful of travellers even in high season.
