What is the water temperature at Bagni San Filippo?

At the source, the water of Bagni San Filippo comes out at about 48 °C. But you don't bathe at the source: the thermal water flows down along the White Creek (Fosso Bianco)a stream with white limestone deposits, and mixes with the cold water of the torrent. The basins are therefore from lukewarm to very hot depending on their distance from the source.

In practice, the pools closest to the Balena Biancathe great limestone cascade, are the hottest, and the water cools as you go down. In winter, rain can cool the basins and make the water murkier. Access is free and open year-round.

Bring water shoes (the limestone is slippery and cuts), take off your silver jewelry silver jewelry…that sulfur blackens, and avoid staying too long in the hottest pools. Rinse off when you head back: the sulfur smell clings to skin and swimsuits. To park and avoid the crowds, read the Bagni San Filippo listing and our guide to free hot springs.
