TUSCAN HOT SPRINGS - FOSSO BIANCO in BAGNI SAN FILIPPO

The Fosso Bianco hot springs and natural pools in Bagni San Filippo

If there's one thing I didn't expect when moving to Tuscany, it's the multitude of freely accessible natural hot springs. Day spas and thermal baths can be found all over the world. But when talking hot baths in the wilderness my first guess would always have been a geyser in Iceland. 

The generous natural pools near Saturnia and the hot springs in Petriolo taught me differently. Both places are well known in Italy, a fact that can make them packed on weekends and public holidays. If you like to take your bath a bit more privately, move on towards Val d'Orcia and explore the Fosso Bianco hot springs near Bagni San Filippo. The waters are as hot as they should be for some comfortable soaking and high in sulfur and calcium (which explains the formation of the white rock and the name of the place).

WHERE
Bagni San Filippo in the Orcia valley, circa 15 minutes from San Quirico d'Orcia and Pienza. See our Southern Tuscany Map
To access the wild Fosso Bianco pools, park your car at the beginning of the village (right before the first houses or walk back up from the parking further down). There is a little signed out trail on the right opposite of a small coffee bar. An easy five minute walk down into the valley will get you to the wild pools. The best time to do so is from November to April. The thermal bath & hotel is closed during those months, which results in more water in the wild pools. 

It may be thanks to the big 'DANGER - No Climbing, No Bathing' signs, that the Fosso Bianco natural springs are less busy than the ones in Petriolo and Saturnia. The signs were put up by the council of Castiglione d'Orcia, in case the white calcium rocks ever felt like crumbling. Luckily Italians are quick to find use for a sign like that.

If unlike the intrepid traveler, you'd rather shower after your bath to avoid the smell of rotten eggs in your hair, Bagni San Filippo also offers a 'proper' pool which belongs to the hotel Terme San Filippo. Personally I love to do the wild thing, but I also like the atmosphere of the hotel pool. It's rather lay-back, and the blue and white tiles make for a nice sixties vibe. That also counts for the pricing: hard to find lower entree fees to a thermal pool anywhere in Tuscany.

Adult day ticket Mon-Fri 10€ / Sat-Sun 12€; Kids day ticket Mon-Fri 6€ / Sat-Sun 8€
Reduced price afternoon tickets are available from 3pm: adults Mon-Fri 7€; Sat-Sun 9€; kids Mon-Fri 4€ / Sat-Sun 6€
The public pool is right next to the hotel at the end of the small village.
The Bagni San Filippo pool and hotel normally close from beginning of November to the end of March. Check for current opening times on their website. If you happen to be in the area during cold months you can always try the lovely pool in Bagno Vignoni. More expensive but open during most winters.

TUSCANY'S BEST HOT SPRINGS: A MAP OF SULFUROUS SOAKING AND WILDERNESS DIPS

A quick round up of my favorite wild hot springs and historic bath towns in Tuscany (more detailed information on spas and rock pool bathing can be found in the single articles the links will lead you to).  WILDERNESS POOLS   PETRIOLO  half an hour to the south of Siena. With its steaming hot water in the upper row of pools a favorite of mine on icy cold winter mornings. The Farma river passes right next to the hot springs. So be courageous and have a splash to try the benefits of kneipping.   SATURNIA  the biggest, most southern and also Italy's best known (and loved!) wilderness pools. The closest option for a soak if you arrive from Rome. To be avoided on weekends.  FOSSO BIANCO  in the Val d'Orcia is a spectacular sight hidden away in the woods below Bagni San Filippo. The shady surroundings make of these natural springs a nice location in the summer.  BAGNO VIGNONI  has a lovely pool below the small waterfall. However, the water arrives from the medieval t

FONTEMORSI: ORGANIC WINE TASTING ON THE ETRUSCAN COAST

In the wine world the Tuscan coast equals Bolgheri and Sassicaia. No other wine has done as much to turn the lay-back beach side paradise south of Livorno into a famous wine growing region as the prestigious Sassicaia from Tenuta San Guido. But whilst the rise of Supertuscans blended from French grape varieties may resemble a fairy tale story, it shouldn't keep you fro m drinking Sangiovese wines in the smaller and lesser known wineries along the Tuscan shore.
