Balneario de Caldelas de Tui, in Galicia, draws bicarbonate water at 41°C. Indoor pools, massage, and a sauna are available in this spa town in Pontevedra province, close to the Portuguese border.
Insider tip — Perched above the Mino River valley on the Galicia-Portugal border, this balneario channels bicarbonate waters at a robust 41°C from granitic fissures deep beneath the rolling green hills. The lush Atlantic climate of Pontevedra province creates a steam-wreathed ambiance particularly vivid on cool autumn mornings. Bicarbonate waters here are traditionally prized for digestive and dermatological cures. Ask staff about the riverside walking path that follows the Mino south toward the Portuguese town of Valenca.
