Embark on a moderate 6.3-mile (10.2 km) hike along the Farma stream and through the Tuscan Maremma, taking approximately 2 hours and 50 minutes to complete. This trail offers a unique blend of natural beauty, leading you directly along the Farma riverbed, where you will navigate wet stones and sometimes ankle to knee-deep water. You will also pass through ancient cork oak forests and spectacular gorges with rocks dating back to the Carboniferous period, gaining about 618 feet (188 metres) in elevation.
While parts of the route are easily accessible, hiking along the riverbed demands good balance and sure-footedness. This moderate trail requires good fitness, and sturdy shoes are essential; high and structured hiking boots along with trekking poles are recommended for your comfort and safety. Be prepared for diverse terrain, including some less-trafficked asphalt roads, as you explore the unspoiled nature reserves of the Val di Merse.
The highlight of this trail is undoubtedly the ancient Petriolo Thermal Baths, known since Roman times, where sulfureous waters gush out at 43°C (109°F). You can experience these therapeutic waters in natural pools like Pozzo dell'Inferno and Vascone, where the warm spring water mixes with the cooler river currents. This unique setting provides a regenerating experience, allowing you to alternate between warm thermal basins and refreshing river waters, offering a rustic escape from mass tourism.

Warning! The path is impassable starting about 1 km after the Abbey of San Galgano, unless you have a machete. Francesco confirms April 2025. In particular, the path is impassable (November 2025) since it is forced between the fence of the "San Galgano" hunting reserve and the narrow strip of dense woodland on the banks of the Merse River. We had to turn back!

Built in the 13th century in Gothic style and dedicated to the saint from Chiusdino, today it is completely in ruins: only the walls remain standing, with the apse still in evidence, perfectly facing east, while on the upper part of the facade there are two pointed windows. The roof of the Abbey of San Galgano is no longer there today. The "official" version says that it deteriorated and then fell over the centuries, while an alternative version, according to some legend and according to others truth, states that it was originally made of lead, and was sold by Girolamo Vitelli in 1550. Whatever the truth behind the roof of the abbey, after some restoration attempts that went badly, at the end of the 18th century it was deconsecrated and left to the elements until the present day. The ruins of the Abbey of San Galgano, with its profile still intact and immersed in the Tuscan countryside, offer a truly incredible and particular view. In addition to the roof, the floor is also missing, which during the summer turns into a grassy blanket, while you can still see a transept with three naves and 4 chapels with cross vaults. Next to the Abbey of San Galgano there is the cloister, which was rebuilt at the beginning of the last century, using the original materials. Some accessory rooms are also very beautiful, which can also be visited with the entrance ticket to the abbey, including the chapter house, where the monks originally met to deliberate the main rules of the community, and the scriptorium, which was the place where the monks copied the manuscripts.

The bridge no longer exists. I didn't feel like watching it with small children: too much current. Too bad we have to go back!
