Termas de Amarante is a sulphurous thermal spa located in or associated with the Amarante area, a historic market town in northern Portugal known for its elegant baroque bridge over the Tâmega River and its devotion to Saint Gonçalo, the patron saint of lovers. The naturally sulphurous spring waters have been valued in the Portuguese thermal tradition for well-being and relaxation, drawing visitors to a setting that combines mineral water heritage with the cultural richness of one of the most picturesque towns in the Minho region.
Insider tip — Termas de Amarante sits on the Tamega River valley in northern Portugal-adjacent Galicia, where sulfurous waters have been channeled since Roman times. The spring emerges at a consistent 38°C with a distinctive hydrogen-sulfide scent typical of this granite-rich terrain. Bathers traditionally soak in stone-lined pools fed directly from the source. The surrounding riverside landscape of vineyards and eucalyptus groves adds a pastoral dimension to the thermal experience.
