Corno Grande is the highest point in the Apennine Mountains, situated in Abruzzo, central Italy. Part of the Gran Sasso massif, it is the highest peak of the Italian Peninsula at 2,912 metres (9,554 ft). It is the highest peak in mainland Italy outside of the Alps, and the second highest in the entire country outside the Alps, after Mount Etna in Sicily. It has significant vertical relief on the north side, though its south side is less elevated than the adjacent Campo Imperatore plateau.
