Asinara is an Italian island of 52 km2 (20 sq mi) in area. The name is Italian for "donkey-inhabited", but it is thought to derive from the Latin "sinuaria", and meaning sinus-shaped. The island is virtually uninhabited. The census of population of 2001 lists one man. The island is located off the north-western tip of Sardinia, and is mountainous in geography with steep, rocky coasts. Because fresh water is scarce, trees are sparse and low scrub is the predominant vegetation. Part of the national parks system of Italy, the island was recently converted to a wildlife and marine preserve. It is home to a population of wild Albino donkeys from which the island may take its name.
Asinara is located at the north-western tip of Sardinia. It is a territory of 51.9 km2 (20 sq mi) with a length of 17.4 km (11 mi) and a width which ranges from 290 m (951 ft) at Cala di Sgombro to 6.4 km (4 mi) of the northern part, as well as 110 km (68 mi) of coast length. The highest point, at 408 m (1,339 ft), is Punta della Scomunica. The territory is entirely state property. The island is formed by four mountainous sections linked by a narrow, flat coastal belt. The windswept west coast is steep and rocky with a very deep sea bottom. The west coast turns down towards the bay of Asinara.
