12 Hidden Hot Springs Near Florence: Escape the Crowds in 2025 (Local's Guide)
Forget the crowded museums and queues; 2025 is the year to discover a different side of Tuscany. This guide will lead you to tranquil thermal springs, many of which are free to access and offer a truly authentic Italian experience. From secluded waterfalls to historic spa towns, get ready to immerse yourself in the region's natural beauty and rejuvenating waters. While this guide includes some of the more well-known springs, the focus is on how to enjoy them like a local, away from the largest crowds. These hidden gems provide a unique opportunity to connect with nature, experience the therapeutic benefits of the thermal waters, and discover the charm of the Tuscan countryside.
Bagni di San Filippo: Tuscany's Free Thermal Springs (Closest to Florence)
Just a scenic drive south of Florence, Bagni di San Filippo is a natural wonder. These free thermal springs are characterized by stunning white calcium formations, creating a surreal landscape that feels like stepping into a fairytale. The most famous formation is the "Balena Bianca" (White Whale), a massive cascade of white rock, but the whole area is dotted with pools and small waterfalls where you can relax and enjoy the warm, mineral-rich waters.
Fosso Bianco: Florence's Secret Thermal Waterfall (Hidden Gem South of City)
Within the larger area of Bagni di San Filippo lies Fosso Bianco, a truly hidden gem. Follow a short trail through the woods, and you'll discover a series of turquoise pools fed by a warm thermal waterfall. This is a favorite spot among locals for a secluded soak, surrounded by the tranquility of nature. Remember to bring water shoes as the rocks can be slippery. It's best to visit during the week or in the early hours of the morning to avoid any potential crowds. The water temperature here is perfect for a relaxing bath, and the surrounding forest provides shade and a sense of seclusion.
The Balena Bianca: A Natural Wonder
The Balena Bianca is the centerpiece of Bagni di San Filippo. This enormous calcium formation resembles a giant white whale and is a testament to the power of nature. The warm waters that flow over it are rich in minerals, making it a popular spot for a natural spa treatment. You can climb on the formation (be careful, as it can be slippery), find a secluded pool, or simply admire its beauty from afar.
Saturnia Hot Springs: Local's 2025 Guide to Avoiding Crowds
Saturnia is perhaps the most famous of Tuscany's hot springs, and for good reason. The cascading waterfalls and naturally formed pools are a sight to behold. However, its popularity can lead to overcrowding. To experience Saturnia like a local in 2025, consider visiting during the off-season (spring or autumn) or early in the morning. Weekdays are generally less crowded than weekends. Another great tip is to explore the area beyond the main Cascate del Mulino. There are other, less-known pools and streams in the vicinity where you might find more solitude.
Cascate del Mulino: Saturnia's Free Thermal Waterfall (Insider Tips)
The Cascate del Mulino is the iconic image of Saturnia. These free-to-access thermal waterfalls are a must-visit. The water cascades down a series of naturally formed terraces, creating shallow pools perfect for soaking.
- Insider tip: Arrive before 8 am or after 6 pm to enjoy a more peaceful experience. The light during these hours is also magical for photography.
- Bring water shoes and be prepared for a bit of a sulfur smell, which is natural and a sign of the water's mineral richness.
- Parking can be difficult, consider parking further away and walking to get the best experience.
- Consider bringing a waterproof bag for your belongings.
Beyond the Cascate: Exploring Saturnia's Other Pools
While the Cascate del Mulino is the most famous spot, the area around Saturnia is full of other thermal springs. If you're willing to explore, you can find smaller, less crowded pools along the river. Ask locals for directions or follow the steam rising from the ground – you might discover your own private thermal paradise!
Petriolo Hot Springs: Historic Thermal Baths Near Florence (Off-the-Beaten-Path 2025)
The Petriolo Hot Springs, known since Roman times, offer a unique blend of history and relaxation. These thermal baths are located along the Farma River and are known for their high sulfur content, making them particularly therapeutic. The waters are said to be beneficial for respiratory and skin conditions. For a truly off-the-beaten-path experience in 2025, visit during the week and explore the nearby ruins of the medieval fortifications.
Terme di Petriolo: Luxury Spa Experience Near the Farma River (Florence Day Trip)
While the natural pools of Petriolo are free to access, you can also indulge in a more luxurious experience at the Terme di Petriolo, a modern spa facility built around the ancient springs. Enjoy a range of treatments, thermal pools, and relaxation areas. This makes for a perfect day trip from Florence, combining the natural beauty of the Farma River valley with the comforts of a high-end spa. There are also a number of agriturismos nearby that offer farm to table dining experiences. They offer various packages, including day passes and overnight stays. You can enjoy mud baths, massages, and other therapies that utilize the healing properties of the thermal waters.
The History of Petriolo: From Romans to the Renaissance
The hot springs of Petriolo have been used for centuries. The Romans were the first to build baths here, and the remains of their structures can still be seen today. During the Middle Ages, Petriolo was a fortified town, and the ruins of its walls and towers add to the historical charm of the area. The springs were even frequented by the Medici family during the Renaissance, who believed in their healing powers.
Bagno Vignoni: Ancient Thermal Pools & Medieval Village (Easy Day Trip from Florence)
Bagno Vignoni is unlike any other hot spring destination in Tuscany. Instead of a river or waterfall, the heart of this medieval village is a large rectangular pool of thermal water, surrounded by historic buildings. While you can't swim in the main pool (it's a protected monument), the nearby Parco dei Mulini offers a chance to soak in the same therapeutic waters. This unique setting makes Bagno Vignoni a must-visit for history buffs and those seeking a truly unique hot spring experience.
Parco dei Mulini: Bagno Vignoni's Free Thermal Baths (Historic Park)
The Parco dei Mulini (Park of the Mills) is a free-to-access area where you can bathe in the warm waters that flow from the main square of Bagno Vignoni. This historic park, with its ancient mill ruins, offers a unique setting for a relaxing soak. The pools here are shallower and a bit cooler than some of the other springs, making it a great choice for families. The town is also home to a number of shops that sell local pecorino cheese and cured meats. You can also enjoy a meal at one of the restaurants overlooking the thermal pool in the main square.
Exploring the Medieval Village of Bagno Vignoni
Beyond the thermal waters, Bagno Vignoni is a charming medieval village worth exploring. Wander through its narrow streets, admire the historic architecture, and enjoy the tranquil atmosphere. You can visit the Church of San Giovanni Battista, which overlooks the main square, or simply relax in a café and soak up the ambiance. Consider having lunch or dinner at one of the restaurants overlooking the thermal pool – it's a truly unique dining experience.
Best Time to Visit Florence's Hot Springs: 2025 Weather & Crowd Guide
The best time to visit Florence's hot springs depends on your priorities: crowds, weather, or a mix of both.
Spring (April-May): The Ideal Season for Hot Spring Hopping
Spring is arguably the best time to visit. The weather is mild and pleasant, perfect for enjoying the outdoors. Wildflowers are in bloom, adding to the beauty of the Tuscan countryside. Crowds are smaller than in the summer months. The temperatures are ideal for soaking in the thermal waters, and you can comfortably explore the surrounding areas.
Summer (June-August): Long Days and Hot Temperatures
Summer offers the longest daylight hours, giving you more time to explore. However, it's also the peak tourist season, so expect larger crowds, especially at the more popular springs. If you visit in summer, arrive early in the morning or late in the evening to avoid the midday heat and the largest crowds. Be prepared for hot temperatures, and bring plenty of water, sunscreen, and a hat.
Autumn (September-October): Mild Weather and Harvest Season
Autumn is another excellent time to visit. The weather is still mild, and the crowds begin to thin out. The grape harvest season is in full swing, making it a great time to combine your hot spring visit with wine tasting in the Tuscan countryside. The changing colors of the leaves add to the beauty of the landscape.
Winter (November-March): A Tranquil Escape
Winter offers the fewest crowds and a unique, tranquil atmosphere. The contrast between the cold air and the warm water can be invigorating. Some hot springs may be less accessible in winter due to weather conditions, but those that are open offer a peaceful retreat. Imagine soaking in a warm thermal pool while surrounded by a snowy landscape – it's a truly magical experience.
How to Get to Florence's Hot Springs: Car, Train & Bus Directions (2025)
Renting a Car: The Most Flexible Option

It gives you the flexibility to explore at your own pace and combine your hot spring visit with other attractions in the Tuscan countryside. Road conditions are generally good, though some roads can be narrow and winding.
Driving Tips for Tuscany
- International Driving Permit: If you're not from the EU, you'll likely need an International Driving Permit in addition to your driver's license.

- Parking: Parking can be limited near the hot springs, especially during peak season. Consider parking a bit further away and walking to avoid congestion.
- GPS: A GPS or a reliable map app is essential for navigating the countryside.
Train and Bus: Budget-Friendly but Less Convenient

- Check the Trenitalia website for train schedules.
- Local bus companies like Tiemme operate regional routes.
- Be prepared for longer travel times and potential delays.
Organized Tours: A Hassle-Free Alternative
If you prefer not to drive, consider joining an organized tour from Florence.

This can be a good option if you're short on time or prefer a more structured experience.
