About Saturnia – Cascate del Mulino
Free natural cascades in the Tuscan countryside where 37.5°C sulphuric water tumbles over travertine pools. No tickets, no closing time — just park and walk in.
Evenings and the off-season are quietest. The sulphur smell is part of the deal; bring water shoes for the travertine, which can be slippery.

Getting there
The Cascate del Mulino sit just outside Saturnia village in southern Tuscany, about 2.5 hours south of Florence and 2 hours north of Rome by car. A car is essential - public transport is impractical. Park in the signed lot and walk a few minutes down to the falls.
Who it suits
Everyone who likes their hot springs wild and free: couples, families, photographers and road-trippers. There are no tickets, no closing time and no facilities, so it suits self-sufficient travellers best.
Safety & etiquette
The water runs at a steady 37.5C - test the upper pools, which are hottest. Travertine is slippery: water shoes are strongly advised. The sulphur smell is normal. Go in daylight if it is your first visit, and never leave valuables visible in the car.
