The Terme di Petriolo—or, Petriolo Thermal Baths—are nestled in the green hills between Val di Merse and Maremma, within a natural landscape that offers many opportunities for hiking, trekking and visits to the nearby Basso Merse Nature Reserve.
The waters of the Petriolo Thermal Baths gush out at a temperature of 109 °F (43 °C) directly from the spring located along the Farma stream. The characteristic sulfurous odor is due to the high concentration of hydrogen sulfide, an element with known therapeutic properties. It is also rich in carbon dioxide, calcium, fluoride and various minerals such as chloride, sulfate and hydrogen carbonate.
The waters greatly benefit the joints and muscles, helping to reduce muscle stiffness, relieve pain and offering an anti-inflammatory action, which is particularly useful for those suffering from osteoarthritis. Also good for the respiratory tract, these waters even have a decongestant effect and promote the elimination of mucus. Likewise, these baths are good for the skin, thanks to the anti-inflammatory, regenerating and purifying properties.
Known as early as Roman times, the Petriolo Baths were much frequented by illustrious people including members of the Medici family, churchmen such as the Pope and cardinals, along with many a noble.
The Petriolo Thermal Baths offer a wide range of spa and wellness services, including therapeutic thermal pools where you can relax and rejuvenate the mind and body. Soaking in these warm waters helps to release accumulated tension, relieve daily stress and regain a natural mental and physical balance.
The baths likewise offer thermal muds, massages with essential oils, inhalations and aerosols. In addition, the Bistrot di Petriolo offers typical Tuscan dishes and aperitifs, while Locanda di Petriolo has lodging available for those who wish to stay in the beautiful Val di Farma.
