General information about Bagni San Filippo

Bagni San Filippo and its hot springs are located about 60 kilometers south of the city of Siena and it’s one of the most beautiful attractions in the Val d’Orcia. The village itself is tiny with only 90 inhabitants, yet there is a small store as well as a handful of restaurants and cafes. There is also a spa hotel with thermal pools. The village is named after Prior Filippo Benizi, who discovered the springs and is said to have mentioned them in writing for the first time in 1271.

Bagni San Filippo is considered the oldest natural and at the same time man-made spa in the world, fed directly by a hot spring. Situated in an almost fairytale-like setting, amidst green dark woods, you can relax in the blue pools of a warm river. It is even believed that the Etruscans and the Romans bathed here. The huge white cascades with the sinter pools are a real eye-catcher and form an almost surreal ambience.

The hot springs are located, as already mentioned, directly in the forest next to the small village of Bagni San Filippo. From the parking lots at the top of the road a short 10-minute walk along a path leads down to the river, the so-called Fosso Bianco. Already during the walk you can perceive the sometimes quite strong sulfur smell of the healing springs.

Bathing in nature

Locals and tourists appreciate the beneficial effects of the Bagni San Filippo springs and are fascinated by the experience of bathing in the middle of the forest and in the warm river water. Keep in mind, however, that there are no sanitary facilities or changing rooms on site. Here you are completely in nature, which is what makes a visit actually so appealing.

These hot springs are sulfur springs, which promise pleasant bathing pleasure with 25 ℃. The slightly milky water testifies to a high mineral content and makes the pools shine in turquoise colors in good light. Over a length of around 2 kilometers, the river offers a wide variety of terraces to splash around, with the most beautiful spot definitely being in front of the travertine rock “Balena” – i.e. the so called white whale.

Tip: In general, sulfur baths should not be longer than 15 minutes and the bath may be repeated no more than 4 times a day.

The healing effect of the spring

The thermal springs of Bagni San Filippo are considered to have a healing effect due to the large quantity of minerals such as calcium, magnesium, sulfur and sulfate. Bathing in the river is healthy especially for the joints and the bones, but also for the skin and the respiratory organs.

Those who would like to have treatments should visit the spa hotel located in the village. For an entrance fee of about 10 euros you can bathe and relax in the pools. In addition, curative massages, wraps and treatments are offered.
