It covers about 7000 hectares between the Valley of Cornia and Pecora, in the hilly system between Massa Marittima and Suvereto. These hills, of medium altitude, are covered mostly by forests of oak, and constitute a landscape plant closely related to human action, in particular to the production of coal and cut of the forest.

Of great interest it is also the fauna, for the large number of ungulates in the wild boars, deer and roe deer.

In the park there are several itineraries for lovers of trekking, horseback or mountain bike.



In the heart of the park the signs of man emerge from the remains of alum quarries and those of a mining settlement.

In fact, in the early decades of the nineteenth century, the Princes of Piombino (Felice and Elisa Baciocchi, sister of Napoleon Bonaparte) built a village (Montioni Nuovo), still visible today, with open pit mining and underground, ovens for cooking or pelleting of the aluminous stone, and of the material transport systems.
