The island has a surface of 51,9 square kilometers, a length of 17,4 km and a width which ranges from 290 meters of Cala di Sgombro to 6.4 km of the northern part; it has a coastal development of 110 km and the highest altitude of 408 metres (Punta della Scomunica). The territory is entirely state property. The marine and underwater island environment is a protected natural area, with an extension of 10.732 hectares over the sea. From a geological point of view, the Asinara is part of the Nurra, on the north-east of Sardinia, made up by more than 80% of granolithic and micacistes rock which characterize the island landscape together with the vegetation of wood and garrigues. Among the metamorphic rocks, great interest is attached to rare black anfiboliti erciniche that are 950 million years old, being the oldest rocks in Italy.
