4 natural hot springs in Tuscany that cost absolutely nothing!
Most tourists in Tuscany pay 40 or 50 euros to sit in a spa. Italians do not. We drive to one of these four places, park the car, and walk in for free.
1. SATURNIA
The most famous one. Thermal water at 37 degrees falls down a natural travertine staircase, forming turquoise pools you can sit in. Open 24 hours a day, every day of the year. No ticket. No booking. In summer it fills up, so locals come at sunrise or late at night. In winter, with steam rising from the water, it looks like another planet.
2. BAGNI SAN FILIPPO
Hidden inside a forest in Val d’Orcia, a hot sulfur stream has carved a massive white travertine formation known as the Balena Bianca — the white whale. Warm pools sit underneath it, surrounded by trees. Completely free, open day and night. Much quieter than Saturnia, and for many Italians, more beautiful.
3. BAGNI DI PETRIOLO
A small river gorge between Siena and Grosseto with one of the oldest free thermal baths in Italy. The Romans bathed here, then the medieval popes. You can still see the original stone walls. Hot sulfur pools sit right next to the cold Farma river, so you alternate: hot pool, cold river, hot pool, cold river. Free, open always.
4. BAGNO VIGNONI
The village itself is famous for a 16th-century thermal pool in the main square, but that one is a monument and you cannot bathe in it. The free pools are a five-minute walk below the village, at the Parco dei Mulini, where the thermal water flows down through the ruins of old mills and forms small cascades and warm pools. Free, open always, with one of the most beautiful views in Tuscany.
Four places. Zero euros. Bring a towel, flip flops for the rocks, and do not wear silver — the sulfur turns it black.
