Balneario Gran Casino de Caldas is located in Caldas de Montbui, a town in Barcelona Province with one of the oldest thermal traditions in the Iberian Peninsula — Roman baths dating to the 1st century AD are still visible beneath the town centre. The sulphurous springs emerge at temperatures around 74°C, among the hottest naturally occurring thermal waters in Spain, and are cooled before use in the spa's treatment pools and hydrotherapy circuits. The 19th-century grand casino building that gave the establishment its name reflects the fashionable resort culture that Caldas de Montbui enjoyed during the Belle Époque, when Barcelona's bourgeoisie came here for summer stays. Today the spa continues both its thermal tradition and modern wellness programming within easy reach of Barcelona's cultural attractions.
