Roughly rectangular in shape and on a major European communications axis north–west and south–east, Serbia & Montenegro borders Hungary to the north, Romania to the northeast, Bulgaria to the southeast, the Kosovo region and Albania to the south, Bosnia & Herzegovina to the west and Croatia to the northwest. The province of Kosovo, now administered by the UN, is in the south, and shares borders with Macedonia (Former Yugoslav Republic of) and Albania. Serbia is dominated by the flat, fertile farmland of the Danube and Tisza valleys.
The scenery varies from rich Alpine valleys, vast fertile plains and rolling green hills to bare, rocky gorges as much as 1140m (3800ft) deep, thick forests and gaunt limestone mountain regions. Belgrade, the capital, lies on the Danube. Montenegro is a small mountainous region on the Adriatic coast north of Albania, bordering Bosnia & Herzegovina to the west. Its small Adriatic coastline comprises the main ports of Bar and those in the Gulf of Kotor.
