Caldes de Malavella in the Gironès comarca of Catalonia is one of the oldest continuously used thermal towns in Spain, with a history of hot spring bathing stretching back over 2,000 years to the Roman settlement of Aquae Calidae. The town is today internationally famous as the birthplace of Vichy Catalan, Spain's most iconic sparkling mineral water, bottled from naturally carbonated bicarbonate springs that emerge at 60°C and are allowed to cool before bottling. Two major spa establishments — Balneari Prats and Balneari Vichy Catalan — offer world-class thermal treatments in beautifully restored 19th-century buildings. The Empordà landscape of cork oak forests, volcanic hills and proximity to the Costa Brava coast gives Caldes de Malavella a particularly rich natural and cultural setting.
Insider tip — Caldes de Malavella sits on the volcanic basalt of the Empordà plain where thermal water emerges at 60°C, one of the hottest natural springs in Spain, and has been in continuous use since Roman times. Two historic balnearios—Prats and Vichy Catalan—occupy the town, with the latter lending its name to Spain's most famous sparkling mineral water bottled here since 1881. The spring water is tempered for bathing while the naturally carbonated drinking water is served chilled throughout Catalonia. The Costa Brava coastline lies just 25 km to the east, easily combined with a wellness stay.
