Sea, coast, plains, hills, mountains, rivers. A wonderful boxy four-sided island surrounded by a legendary sea, Sardinia stretches roughly 260 kilometres top to bottom and measures 120 across. Its coastline features four capes marking the island’s four extremities – Falcone in the north, Teulada in the south, Comino in the east and Argentiera in the west – and is an impressive 1,850 kilometres long, while four large gulfs – Asinara, Cagliari, Orosei and Oristano – one on each side, open up to the sea. A stunning medley of high rocky cliffs and amazing white sandy beaches, the Sardinian coastline stands out for its generous helping of caves and, in the Gallura region, deep funnel-like inlets. Inland, on the other hand, the island is prevalently hill country interspersed, to the west, with two large plains – Campidano and Nurra – and with mountain ranges, including the island’s most imposing massif, Gennargentu. Sardinia is home to three rivers worthy of the name: the Flumendosa, the Coghinas and the longest, the Tirso, which has been dammed to create Lake Omodeo, the largest artificial lake in Italy.
