The National Park of Sibillini Mountains covers an area of 70.000 hectares of protected land. It was established in 1993; the towns included in the park are: Acquacanina, Amandola, Arquata del Tronto, Bolognola, Castelsantangelo sul Nera, Cessapalombo, Fiastra, Montefortino, Montegallo, Montemonaco, Valfornace, Pieve Torina, San Ginesio, Ussita, Visso.
The great limestone massif that stands in the southern Marche includes one of the highest peaks on the Italian mainland - Monte Vettore at 2,476 metres - and the wild tarns and windswept high plains of the Monti Sibillini provide some of the Marche's most spectacular landscapes. The mountains take their name from a legend that one of the sibyls - the prophetesses of classical mythology - hid here in a cave on Monte Sibilla known as the Grotta delle Fate (Cave of the Furies) when she was chased out of the underworld. Chiselled by glaciers and limestone erosion, these mountains possess some outstanding natural sights. These include the high natural tarn Lago di Pilato (tradition makes the unlikely claim that Pontius Pilate is buried here), and the awesome Infernaccio Gorge. Other delights include the great upland plains which are a mass of flowers in spring. The most impressive is the Piano Grande below the village of Castelluccio, famous across Italy for its lentils. Different types of trees can be found in the park : the oak, the hornbeam , the beech , but also natural pastures with very rare and valuable species such as the edelweiss of the Apennines and the willow dwarf, that is considered the world's smallest tree. The fauna is also varied; there are different mammals, such as the wolf, the wild cat, the hedgehog, the roe deer; some birds populate the park too: the golden eagle, the goshawk , the sparrow hawk and the peregrine falcon. In Lago di Pilato lives Chirocefalo del Marchesoni, a reddish crustacean.
