Gran Sasso e Monti della Laga National Park covers a surface area of 150,000 hectares. It is one of the largest parks in Italy. It offers a number of proposals, itineraries and visits for every season thanks to the richness of its habitats, its massifs, and thanks to the charming historical-architectonical evidences it preserves. The Park consists of three mountain groups: Gran Sasso d'Italia chain, Laga massif, and Gemelli Mountains. The Park is also characterized by the presence of the highest peak of the Apennines, Corno Grande (2,912 meters). On this chain there is the one and only glacier of the Apennines, the so-called Calderone, which is also the southernmost glacier in Europe.
