Parco naturalistico delle Biancane in Tuscany

You’re surrounded by dramatic white stone plains. You can hear the water boiling just under the surface and the smell of rotten eggs enters your nostrils. From the white rock around you, plumes of hot steam come up. Le Biancane Nature Park in the Maremma in Tuscany has been known for its volcanic activity and hot springs since ancient times. Above all, you make beautiful hikes in this park!

The view from Parco delle Biancane

Geothermal area in Tuscany

Half an hour by car over a winding hillside brings us to the Parco naturalistico delle Biancane or Le Biancane Nature Park. This protected natural park is not far from the village of Monterotondo Marittimo. A landscape that is un-Italian but really is located in the middle of the Maremma, in the southwest of Tuscany. A spectacular and almost unearthly landscape where you can make beautiful hikes.

It is a geothermal area. Over here the heat of the core of the earth has reached the surface of the earth. This makes that you can see plumes of steam all over the landscape. The steam has a temperature of about 100 ° C. This steam consists mainly of water vapor, combined with a multitude of gases, including hydrogen sulfide. Because of this, the whole area smells like sulfur or rotten eggs, not a very pleasant smell.

Hiking in Parco delle Biancane

Do not let this stop you from visiting the parc! The Parco delle Biancane is one of the most beautiful places in Tuscany. Over the years, the hydrogen sulphide has ensured that in some places the rocks have become pure white. Together with the steam this creates an unearthly landscape.

Several hiking trails have been set out, so you can explore this extraordinary area. First we walk past a number of wells. “This is acqua forte, heavy water.” explaines our guide. “It’s called so because there’s a lot of metal in it.” There is a small stream along the path. The guide takes a thermometer. “25 degrees, but there are also sources here where the water on the surface easily hits 50 degrees.”

Pure white rocks

Soon we arrive at the white rocks. It looks like a white stone waterfall has been rolled off the mountain. The heat that comes up from deep into the earth here ensures that the rocks under your feet are heated. The guide puts a thermometer between the stones and the grit, which quickly indicates 95 degrees celcius. Between these warm rocks and the steam that comes out of the ground, we have the impression that we ended up in an unreal landscape

The rocks are dazzling white. The acidity of the water and the heat have slowly decolourized the stones. Over here almost no plants can grow, but in some places the white is interrupted by the dark green of small plants and cork trees that stand bravely in the area. A little further on, the stones are colored in all shades of red and orange, the original color of the rocks.

Even the silence in this remote place contributes to the unearthly feeling, only occasionally interrupted by the hissing and puffing of the steam.

Geothermal museum Larderello

We walk down to the parking lot. The guide points out that there are several modern and very large power plants in the beautiful Tuscan countryside. What turns out? This part of Tuscany was one of the first places where geothermal energy was extracted on a large scale. In 1913 the first geothermal power plant was built at Larderello. Today, the power stations supply energy to a million Italian households, in addition to the energy generated by fossil fuels.

The Geothermal Museum Larderello (the Museo della Geotermia) tells the history of the generation of this energy from underground heat sources. Interesting for those who want to know more about the development of this area.
