It shares borders with Bosnia-Herzegovina, Bulgaria, Croatia, Hungary, the Republic of Macedonia, Montenegro, Romania and Albania through the disputed territory of Kosovo. It is landlocked, although access to the Adriatic Sea is available through Montenegro, and the Danube River provides shipping access to inland Europe and the Black Sea.
