Font de Fontcalda is a naturally warm sulphurous spring located in a dramatic gorge of the Canaletes River in the Terra Alta region of southern Catalonia, Spain, where the warm mineral waters emerge at the base of a striking limestone canyon. The site has been a place of pilgrimage and bathing since medieval times, associated with a small chapel dedicated to the Virgin of Fontcalda that overlooks the spring. The combination of geological drama, sacred heritage, and sulphurous water makes Fontcalda one of the most evocative and visited natural thermal sites in Catalonia.
Insider tip — Font de Fontcalda — meaning hot fountain — is one of Catalonia's most scenic thermal springs, tucked into a dramatic gorge carved by the Canaletes River south of Gandesa in Terra Alta. The sulfurous waters have been revered since medieval times, and the site is flanked by a small hermitage perched on the canyon wall. The setting within a natural reserve makes the approach on foot through the gorge part of the experience.
