The path to Fosso Bianco

Access to the entire Fosso Bianco area is free. The area is quite large, the first basins that meet along the road and going up the stream are characterized by very warm transparent waters.

Continuing instead on the main road and then along the path that runs alongside the river you reach the Cascata della Balena (Whale’s Waterfall), a huge block of limestone formed by the sediments of the white hyperthermal waters.

This water, mixing with the stream, gives the typical white-blue color that creates strong contrast with the surrounding forest.

Going further downstream you reach the thermal establishment where the abundant waters of the swimming pool are released into the Fosso Bianco, increasing the temperature.

Swimming in the Magic White Whale Waterfall

Bagni San Filippo Hot Springs

The waterfall it is called White Whale for its resemblance to the mouth of a whale, the most suggestive limestone formation of the White Fosso Hot Springs.

Here the hottest waters not used by the spa flows at 48º from the nearby spring, guaranteeing a temperature so high as to allow you to bathe even out of season.

The quantity and the path of the water coming down from the waterfall changes quite frequently, transforming the scenery iwith new shapes and colors.

In fact, especially in winter, the thermal waters mix with rainwater rich in organic or mineral material which, depositing together with the limestones, creates shades of color on green or reddish-brown.

Often you can find small pools built by the inhabitants of the place or by tourists directly under the vertical wall of the waterfall to collect the warmer waters before they mix with those of the Fosso Bianco.

These basins are formed by simply letting the water flow through dry stone walls composed of a few stones, twigs and leaves.

On the bottom of these deposits the precious thermal mud used for the treatment of the skin of the face and body.


Passing Water

Passing Water is a small source downstream known for its mineral wealth and chemical composition.

It can be reached via a short pedestrian path near the Citerni Park downstream from the town. Some inhabitants and vacationers of the spa resort use this water during meals.
