The entire park is characterised by white rocks, which are coloured by the hydrogen sulphide emissions that erupt from geysers in the ground and turn the limestone into gypsum.
The Biancane have an unusual, but alluring beauty all of their own. The pools of water boil at a constant temperature of between 100-150°c. The steam and shooting geysers add to the mystical atmosphere, while the geothermal wells are harnessed to produce electricity throughout Grosseto.
