O Baño — Galician for 'The Bath' — is a naturally sulphurous thermal spring in Galicia, northwestern Spain, whose simple, definitive name conveys the central importance of this site as the communal bathing place for the local community. Galicia is endowed with an extraordinary density of hot springs, and O Baño represents the most essential expression of this geothermal wealth: a named, shared, communal bathing place where warm mineral water has served the health and wellbeing of local people for generations. The spring offers an authentic and unadorned encounter with the living thermal heritage of the Galician landscape.
Insider tip — O Bano is one of the public thermal bathing points in Caldas de Reis, a Galician town in Pontevedra where sulfurous hot springs have been used continuously since Roman times. The waters emerge at around 40°C from granitic faults and are lightly sulfurous, known for their skin-softening and rheumatic benefits. The town is a key stop on the Portuguese Camino de Santiago, and many pilgrims pause here to soak tired feet before the final stretch to Compostela.
