Lago Termal de Alhama de Aragón is a picturesque thermal lake fed by naturally sulphurous hot springs in Alhama de Aragón, a historic spa town in the Zaragoza province of Aragon, Spain, where geothermal waters have attracted bathers since antiquity. The thermal lake — set within the scenic Jalón River gorge — creates a naturally beautiful bathing environment that has made Alhama de Aragón one of the most celebrated thermal destinations in central Spain. The sulphurous waters, emerging at temperatures around 34 degrees Celsius, are prized for their beneficial effects on rheumatic, dermatological, and respiratory conditions.
Insider tip — The thermal lake at Alhama de Aragon sits within a dramatic gorge carved by the Jalon River in the Iberian System mountains. The natural sulfurous waters have attracted visitors since Roman times, and the outdoor thermal lake offers a remarkable setting among limestone cliffs. Arrive early to secure a spot along the natural stone edges where the water bubbles warmest.
