Discover more about Terme San Filippo

Terme San Filippo, located in the heart of Tuscany's Val d'Orcia, is a captivating natural hot spring area that has attracted visitors since Roman times. The thermal waters, rich in minerals, emerge from the ground at a temperature of approximately 48°C (118°F). Over centuries, these waters have sculpted the landscape, creating unique calcium formations, most notably the Balena Bianca, or White Whale. The area offers a series of natural pools where visitors can soak and enjoy the therapeutic benefits of the thermal waters. The contrast between the white calcium formations, the blue-green water, and the surrounding green forest creates a mesmerizing and otherworldly atmosphere. The thermal waters are known for their high concentrations of calcium, magnesium, and sulfates, believed to have analgesic, anti-inflammatory, and muscle-relaxing properties. The mud at the bottom of the pools is also used as a natural skin treatment. The village of Bagni San Filippo itself is small and charming, with a few restaurants and cafes. The area is steeped in history, with evidence suggesting that both the Etruscans and Romans utilized the springs for their healing properties. In the 16th century, Cosimo I de Medici restored the baths, further cementing their importance. The village's name is derived from San Filippo Benizi, a priest who sought refuge here in the 13th century. Visiting Terme San Filippo is a unique experience that combines relaxation, natural beauty, and a touch of history. It's a place where you can escape the hustle and bustle of modern life and immerse yourself in the tranquility of the Tuscan countryside.
