Its 15,522 inhabitants (2011) make it the second most populous Adriatic island after Krk and the most populous Croatian island not connected to the mainland by a bridge. The population are almost entirely ethnic Croats (95.74%).
The island of Korčula belongs to the central Dalmatian archipelago, separated from the Pelješac peninsula by a narrow Strait of Pelješac, between 900 and 3,000 metres (3,000 and 9,800 feet) wide. It stretches in the east-west direction, in length of 47 kilometres (29 miles); on average, it is 8 km (5.0 miles) wide. With an area of 279 square kilometres (108 sq mi), it is the sixth largest Adriatic island. The highest peaks are Klupca, 568 metres (1,864 ft) and Kom, 510 metres (1,670 ft) high.
Main settlements on the island are towns of Korčula, Vela Luka and Blato. Villages along the coast are Brna, Lumbarda, Račišće, and Prižba; Žrnovo, Pupnat, Smokvica and Čara are located inland. The island is divided into municipalities of Korčula, Smokvica, Blato and Lumbarda. The climate is Mediterranean; an average air temperature in January is 9.8 °C (49.6 °F) and in July 26.9 °C (80.4 °F); the average annual rainfall is 1,100 mm (43.3 in). The island is largely covered with Mediterranean flora including extensive pine forests.
The main road runs along the spine of the island connecting all settlements from Lumbarda on the eastern to Vela Luka on the western end, with the exception of Račišće, which is served by a separate road running along the northern coast. Ferries connect the city of Korčula with Orebić on the Pelješac peninsula and Drvenik on the mainland (near Makarska). Another line connects Vela Luka with Split and the island of Lastovo. Fast passenger catamarans connect those two ports with Split and the islands of Hvar and Lastovo. The main Adriatic ferry line connects Korčula with Split, Dubrovnik, Zadar and Rijeka. During the summer there are direct ferries to Italian Adriatic ports.
Korčula is linked to the mainland by a regular ferry service that runs between Dominče, just outside Korčula Town and Orebić. There are numerous other local ferry services including one linking Vela Luka and Lastovo. The main Croatian ferry operator Jadrolinija runs a service linking Korčula Town with Rijeka, Split, Hvar, Mljet, Dubrovnik and (from May to September) Bari. An operator Linijska nacionalna plovidba runs a seasonal service linking Korčula with Drvenik.
There are also bus services that link the island to major cities on the mainland, which reach Korčula using the Orebić ferry service.
Korčula town also has mooring facilities. The western harbour gives shelter from wind though not against the ‘bora’ and north-westerlies. Boat owners are advised to shift to the eastern harbour or to Luka Cove. The port is open to international seaborne traffic as a permanent Port of entry; it offers all types of repairs to hulls and engines at the Brodograditelj Shipyard.
