The thermal springs of Gambassi have been valued since at least the medieval period, and the waters from the Pillo source — rich in sodium bicarbonate and sulphate salts — are particularly recommended for digestive treatments, respiratory conditions, and skin complaints. The spa complex in the old centre connects to a large public garden planted with centuries-old trees, making it a genuinely pleasant setting for a treatment.
The season runs from April to October. Treatments are available on a medical referral or simply as day-visitor wellness packages. The pace is thoroughly Italian and reassuringly unglamorous — this is a functioning health spa used by locals, not a luxury resort dressed up in wellness language. Booking ahead in peak summer months is advisable.
