Dubrovnik has an international airport of its own. It is located approximately 20 km (12 mi) southeast of Dubrovnik city centre, near Čilipi. Buses connect the airport with the Dubrovnik old main bus station in Gruž. In addition, a network of modern, local buses connects all Dubrovnik neighbourhoods running frequently from dawn to midnight. However, Dubrovnik, unlike Croatia's other major centres, is not accessible by rail;[63] until 1975 Dubrovnik was connected to Mostar and Sarajevo by a narrow gauge railway (760 mm)[64][65] built during the Austro-Hungarian rule of Bosnia.

The A1 highway, in use between Zagreb and Ploče, is planned to be extended all the way to Dubrovnik. Because the area around the city is disconnected from the rest of Croatian territory, the highway will either cross the Pelješac Bridge whose construction is currently stalled, or run through Neum in Bosnia and Herzegovina and continue to Dubrovnik.
