Montagna della Majella (called Padre dei Monti - Mountains' Father - by Pliny the Elder and Montagna Madre - Mother Mountain - by the people of Abruzzi) is a high, imposing, wild mountain group which is part of the world heritage of National Parks. The Park consists of four main elements: Majella, a wide and compact calcareous massif, Morrone, Porrara, and Monti Pizzi, with the valleys and the karst planes interposing between them. This National Park is unique for several factors, such as its geographical position, harshness, extension, and climatic changes. It also includes widelands with peculiar wilderness features, the most precious and rare part of the biodiversity national heritage, important not only at a European, but also at a world level.
