Campania has an area of 13,590 km2 (5,247 sq mi) and a coastline of 350 km (217 mi) on the Tyrrhenian Sea. Campania is famous for its gulfs (Naples, Salerno and Policastro) as well as for three islands (Capri, Ischia and Procida).
Four other regions border Campania; Lazio to the northwest, Molise to the north, Apulia (Puglia) to the northeast and Basilicata to the east.
The mountainous interior is fragmented into several massifs, rarely reaching 2,000 metres (Miletto of 2,050 m), whereas close to the coast there are volcanic massifs: Vesuvio (1,277 m) and Campi Flegrei.
The climate is typically Mediterranean along the coast, whereas in the inner zones it is more continental, with low temperatures in winter. 51% of the total area is hilly, 34% mountainous and the remaining 15% is made up of plains. There is a high seismic risk in the area of the region.
