The hot springs at Porretta Terme are the reason the town exists. Several natural springs emerge here with different mineral compositions, and the main thermal complex offers pools, treatments, and day passes. The water is warm, mildly sulphureous, and said to be good for the respiratory system — though most visitors come simply to relax.
The spa facilities have been modernized but retain the slightly old-fashioned atmosphere of a traditional Italian thermal town. The complex sits at the south end of the town center, walkable from the railway station and the central piazza. Day use without treatments is the most affordable option.
