Cascate del Mulino
Saturnia, on the road toward Montemerano · SP10, 58014 Saturnia
A series of natural limestone pools carved by sulphur-rich water flowing at around 37.5C, free to enter and open 24 hours a day, all year round. The wider natural site welcomes dogs kept under control on lead, but for hygiene the actual thermal pools are not the place for a dog to swim, so plan on your dog exploring the travertine terraces and grassy banks around the falls while you bathe in shifts.
🐾 Dogs on lead welcome on the natural site; not inside the bathing pools themselves🕐 24 hours a day, every day of the year⭐ Early morning or after sunset for the quietest, coolest visit
💡 Bring your dog's own water and a towel, and keep them leashed on the approach path, which gets crowded and slippery near the main pools in summer
