In Las Caldas, about 8 km from Oviedo, Aquaxana is the eco-thermal centre of the Blau Las Caldas Villa Termal resort, alongside the historic Royal Balneario and the exclusive Sala de las Columnas. Spread across more than 40,000 m², the complex features striking architecture: a pool area of over 800 m² capped by a dome inspired by Rome's Pantheon, where light and volume play above the water.
Insider tip — Aquaxana occupies the verdant Nalon Valley in Asturias, nestled between the green Cantabrian hills and ancient oak forests. The thermal circuit draws on sulfurous springs that have supplied this valley since the 18th century, and the surrounding landscape is quintessentially Asturian, lush and misty. Pair a session with a visit to the nearby Roman thermal heritage sites along the valley.
