Termas Amarillas is a backcountry thermal spring in the Maule Pre-Cordillera near Linares, where sulfate-rich waters stain surrounding rocks in vivid yellow ochre — giving the springs their evocative name 'Yellow Thermal Springs' — in a setting of native Chilean forest and rolling Andean foothills at around 1,200 meters. The rustic pools are reached via rural dirt roads through vineyards and apple orchards of the Maule Valley, one of Chile's most productive wine regions, providing an authentic and unpretentious alternative to commercial central Chilean thermal resorts. The native coigüe and raulí forest, spring wildflowers, and undisturbed mountain silence surrounding the springs make Termas Amarillas a deeply peaceful backcountry thermal escape.
Insider tip — The Termas Amarillas sit deep in a forested Andean canyon of the Maule Region, where the Rio Cipreses carves through ancient lava flows. The yellow-tinged bicarbonate water gives the springs their name and leaves a silky feeling on the skin. The trailhead requires a two-hour hike through native coigue forest, making this a favourite destination for Chilean trekkers seeking a thermal reward after a strenuous walk.
