This particularity makes it a unique site, as few thermal baths in Tuscany offer such naturally hot water. Their composition is also noteworthy, being particularly rich in sulphur, calcium and magnesium.

During the day, especially in high season, the pools can be busier, although access remains free and open to all.

The archaeological discovery at San Casciano dei Bagni is indeed fascinating news that has shaken up the world of archaeology. In 2022, archaeologists unearthed no fewer than 24 intact bronze statues, as well as more than 10,000 coins, , extracted from the protective mud of the Bagno Grande pool. This priceless treasure, which testifies to ancient devotion and healing practices, is of paramount importance for understanding the Etruscan and Roman history of the region. The mud and thermal water acted as a natural preservative, protecting these works from oxidation for more than two millennia, which allowed an incredible fineness of detail in the sculptures to be preserved.
Currently, while waiting for the dedicated museum to open, you can visit the excavation site, located near the thermal baths, to get an idea of the scale of this archaeological work. It is an impressive experience to be so close to the place where these treasures were discovered. The new museum, intended to display these bronzes and other artefacts, will open its doors at the Palazzo dell’Arcipretura, a 16th-century building located in the historic centre of San Casciano dei Bagni. The opening is scheduled for the end of 2026. In the meantime, to deepen your knowledge of the region’s ancient history, you could explore the 5 must-see Etruscan archaeological sites of Maremma.
For an authentic immersion and a stay away from standardised hotels, I warmly recommend choosing an agriturismo in the surrounding countryside of San Casciano dei Bagni. That is where you will discover the true heart of the Tuscan Maremma, with its rustic charm and warm hospitality. The agriturismi offer a unique experience, often run by local families, where you can savour local produce and enjoy breathtaking landscapes.
Here are a few suggestions to help you choose: the Agriturismo Le Radici in San Casciano dei Bagni is ideal for its immediate proximity to the thermal baths, which is very practical after a day of bathing. If you are looking for a panoramic view of the Tuscan hills, the Agriturismo San Casciano, also located in San Casciano dei Bagni, will be perfect. For absolute authenticity and calm, a little further away but just as charming, the Agriturismo Il Poggio in Celle sul Rigo is an excellent option. Don’t forget to enjoy the typical agriturismo breakfast, often made up of homemade jams and a stunning view over the vineyards. Also enquire about the availability of bicycles or hiking trails directly accessible from the farm, to explore the surroundings without a car. For other options and advice, you can consult my guide on where to stay in an agriturismo in the Tuscan Maremma: the 2026 index.
Beyond the benefits of the hot springs of San Casciano dei Bagni, the region offers a multitude of activities to extend your stay and immerse yourself further in the local culture and nature. An unmissable experience is the discovery of the local gastronomy, notably the famous Pici. These thick hand-rolled spaghetti are the emblematic pasta of the region and pair wonderfully with the ‘all'aglione’ sauce, made from tomato and giant local garlic. I recommend heading to Celle sul Rigo, a neighbouring village renowned for its family trattorias where you can taste authentic Pici. Also don't forget to try the locally pressed cold-pressed olive oil, whose fiery taste reflects the volcanic terroir.
For lovers of nature and hiking, an ascent of Monte Cetona is an excellent option. This mountain dominates the south of Tuscany and offers trails winding through oak woods and olive groves, in absolute calm. From the summit, you will be rewarded with a breathtaking panoramic view stretching as far as Monte Amiata. Allow about three hours for a pleasant hiking loop. The paths are well marked but retain a wild character, guaranteeing total immersion in nature. These activities allow you to vary the pleasures and discover the richness of the wild Maremma between land and sea in Tuscany, perfectly complementing the thermal experience.
The Caldagna is the name given to the main and largest of the stone washing basins located at Bagno Grande, the free pools of San Casciano dei Bagni. It is a central element of the wild and authentic thermal experience you can have at this site. Its importance lies in the fact that it is there that the heat of the water is most lively and intense, offering a particularly enveloping and soft sensation on the skin. Despite the natural mineral deposit, the water there is remarkably clear, inviting relaxation and rejuvenation.
Historically, these stone washing basins, including the Caldagna, were used as laundry places by the inhabitants, but they have always been fed by the hot springs, turning a daily chore into a moment of well-being. Today, they offer a completely free «rustic luxury» accessible to all, allowing a direct connection to the millennia-old history of the place. It is crucial to respect the silence and cleanliness of this exceptional place, leaving no litter behind, in order to preserve this fragile natural and historical heritage for future generations. Immersion in the Caldagna is a unique sensory experience, a true invitation to disconnect, where body and mind are soothed by contact with this sacred water.
