Caldas de Santa Maria Madalena, in Arouca, Aveiro District, Portugal, offers bicarbonate water at 30°C, pH 8. Indoor and outdoor pools, a sauna, hammam and massage complete this northern Portuguese spa stop.
Insider tip — Caldas de Santa Maria Madalena lies in the Serra da Freita foothills near Arouca in northern Portugal, where cool granite highlands descend toward the Paiva River gorge. The mildly bicarbonate springs emerge at a gentle 30°C through granitic fractures, making them more refreshing than intensely thermal — ideal for long, soothing soaks. The area is famous for the Passadicos do Paiva boardwalk trail nearby, and combining a thermal soak with the dramatic river-gorge hike makes for an outstanding wellness day. The spring's modest temperature suits sensitive skin and children well.
