This little idyll appears unexpectedly. The first thing that caught my attention was the croaking of the frogs.

Biancane Nature Park

Highlight • Natural Monument

The Biancane Nature Park (the name Biancane derives from the white color of the rocks) is an extraordinary area in which geothermal energy has decisively characterized the whole landscape. You can follow a guided tour, wearing trekking shoes, and be fascinated by the natural geothermal manifestations that you will observe in large quantities. The shower heads (also called fumacchi) are columns of steam that rise from the ground and dissolve in the air. Bulicami, constantly bubbling mud lagoons caused by endogenous gases. Le putizze, undoubtedly a funny name that indicates the emanations of steam rich in hydrogen sulphide. Le Mofete, gaseous manifestations of carbon dioxide.

Impressive little hike.
It's great in cooler weather as the ground radiates warmth. 😀

Contrary to expectations, there are 😊 geothermal power plants and also this worthwhile path. Tip: continue in the direction of Sasso for about 15 minutes from the top of the pass, then you will see the most beautiful fumeroles.
