The massif covers a map area of about 93.29 km2 (36.02 sq mi), with a minimum elevation of 450 m (1,480 ft), a maximum elevation of 2,249 m (7,379 ft) and a mean elevation of 1,000 m (3,300 ft).[1]
The southern part of the massif, on the boundary between Molise and Lazio, is the Monti delle Mainarde. Here, historically, the human presence has been not seasonal as in the highest slopes.
