Dubrovnik's Ferry Terminal is located in the Kantafig area of Gruž bay roughly 3 km from the Old Town. All ferries to and from Dubrovnik arrive and depart from here. Destinations served by the port include Bari, Rijeka, Split, Stari Grad, Korcula and Mijet.

The primary hub for all ferry travel in Dubrovnik is the Port of Gruž (Dubrovnik Ferry Port), located about 3 kilometers (2 miles) northwest of the historic Old Town. This is where you will catch large car ferries (operated by Jadrolinija) and high-speed catamarans (Kapetan Luka or TP Line) heading to islands like Hvar, Korčula, Mljet, and Brač, as well as international routes to Bari, Italy. The port is easily reachable from the Old Town via a 10-minute ride on local buses (Lines 1A, 1B, or 3). It is important to note that the Old Town Harbor (located on the eastern side of the city walls) is not for the main ferries; it only serves small excursion boats to Lokrum Island and the coastal shuttle to Cavtat. For 2026 travelers, it is highly recommended to book catamaran tickets online in advance during the summer months, as these "fast ferries" are the most popular way to reach Split and the surrounding islands and frequently sell out days before departure.
