Terme di Saturnia (Tuscany)
Perhaps the most famous of Italy’s hot springs, Terme di Saturnia is a natural wonder located in the Tuscan countryside near the town of Saturnia. Legend has it that the springs were formed by the god Saturn throwing a thunderbolt, creating this magical place. The springs flow at a constant temperature of around 37.5°C (99.5°F) and are rich in minerals like sulfur, carbon, and bicarbonate, which are believed to have healing properties, especially for skin and respiratory conditions.
The highlight of Terme di Saturnia is the Cascate del Mulino, a series of naturally formed pools and waterfalls set against a scenic backdrop. The milky-blue waters cascade from pool to pool, creating a terraced effect that allows visitors to bathe in shallow or deeper pools. Best of all, these springs are free to the public, and their natural beauty makes them one of the most picturesque places to relax and unwind in Italy.
Bagni San Filippo (Tuscany)
Also located in Tuscany, Bagni San Filippo is another hidden gem among Italy’s hot springs. Tucked away in the woods of Val d’Orcia, this smaller, lesser-known hot spring is famous for its dramatic limestone formations. The most striking of these is called the “White Whale” (Balena Bianca), a massive, white mineral deposit that resembles a giant whale, created by the flow of hot, mineral-rich waters over centuries.
Bagni San Filippo offers a more rustic, secluded experience compared to the busier Saturnia springs. Visitors can immerse themselves in the warm, blue-green pools that form naturally around the limestone deposits. These springs, which are free to access, offer a peaceful and intimate setting surrounded by the beauty of nature. The mineral-rich waters are said to help with joint and muscle pain, making it a popular spot for those seeking therapeutic benefits as well as relaxation.
Bormio Thermal Baths (Lombardy)
Bormio, located in the Alps of Lombardy near the border with Switzerland, is home to several natural thermal baths that have been enjoyed since Roman times. Bormio is famous for its scenic mountain views, especially in winter when the snow-capped peaks surround the steaming hot springs. There are several thermal baths in Bormio, including the luxurious QC Terme Bagni di Bormio and the historic Bagni Vecchi.
The Bagni Vecchi, or “Old Baths,” are particularly unique, featuring ancient Roman baths, a cave bath, and outdoor pools with breathtaking views of the surrounding mountains. Meanwhile, the Bagni Nuovi, or “New Baths,” offer a modern spa experience with beautifully designed pools and saunas. The mineral-rich waters in Bormio are believed to aid with circulation and respiratory health, and the stunning alpine setting makes this one of the most scenic hot spring destinations in Italy.
Pozza di Venere (Sicily)
For a truly unique hot spring experience, head to Sicily and visit Pozza di Venere, also known as the “Bath of Venus.” Located near Pantelleria Island, this hot spring is situated in a volcanic crater surrounded by stunning Mediterranean scenery. The spring itself is nestled in Lago Specchio di Venere (the Mirror Lake of Venus), named after the Roman goddess of love and beauty. The turquoise-blue water contrasts beautifully with the lush green landscape and the black volcanic rocks that surround it.
The lake’s mud is rich in minerals, making it popular for natural mud treatments that are said to have beneficial effects for the skin. Visitors often coat themselves in the therapeutic mud, let it dry, and then rinse off in the warm waters of the lake. The stunning setting, coupled with the unique spa-like experience, makes Pozza di Venere one of Italy’s most beautiful and off-the-beaten-path hot springs.
Terme di Petriolo (Tuscany)
Tuscany is undoubtedly a hot spring paradise, and Terme di Petriolo is another gem worth visiting. Located in the Siena province along the Farma River, these springs date back to Roman times and are known for their sulfur-rich waters, which flow at a temperature of around 43°C (109°F). Terme di Petriolo’s ancient Roman ruins and the surrounding forests create a scenic backdrop that adds a historical charm to this already beautiful location.
What makes Terme di Petriolo special is its free access to natural pools along the river, making it a popular spot for locals and travelers alike. The sulfur in the water is thought to help with various skin ailments and respiratory issues. Unlike more developed spa resorts, Terme di Petriolo offers a more rustic experience, where visitors can bask in the warm water and enjoy the tranquility of the surrounding nature. The site is especially atmospheric in cooler months when the warm steam rises against the crisp air.
