Piscine Termali di Viddalba, in Sardinia's Sassari province, tap sulfurous, sodium-chloride water reaching 68°C. Indoor pools, massage and a sauna offer a Sardinian thermal experience.
Insider tip — The thermal pools of Viddalba tap one of Sardinia's most powerful geothermal springs in the Gallura sub-region of northern Sardinia, where waters emerge at extraordinarily high temperatures from deep fault systems in the ancient Paleozoic basement. The sulfurous-sodium-chloride composition reflects water that has circulated deep through crystalline rocks before being heated by residual magmatic activity. The pools must be cooled before use, and the mineral richness gives the waters an intensity highly regarded in balneology. The surrounding cork-oak macchia and granite boulder landscape is quintessentially Sardinian.
