Romania (România) is a country located at the crossroads of Central and Southeastern Europe, on the Lower Danube, within and outside the Carpathian arch, bordering on the Black Sea. Romania shares a border with Hungary and Serbia to the west, Ukraine and Moldova to the northeast and east, and Bulgaria to the south.
At 238,391 square kilometers (92,043 sq mi), Romania is the ninth largest country of the European Union by area, and has the seventh largest population of the European Union with 20.2 million people. Its capital and largest city is Bucharest, the sixth largest city in the EU with about two million people. Bucharest was in 2011 number 55 in top 100 world destinations.
Romania’s terrain is distributed roughly equally between mountainous, hilly and lowland territories. The Carpathian Mountains dominate the centre of Romania, with 14 mountain ranges reaching above 2,000 m/6,600 ft, and the highest point at Moldoveanu Peak (2,544 m/8,346 ft). These are surrounded by the Moldavian and Transylvanian plateaus and Pannonian and Wallachian plains. Romania’s geographical diversity has led to an accompanying diversity of flora and fauna.
A large part of Romania’s border with Serbia and Bulgaria is formed by the Danube. The Prut River, one of its major tributaries, forms the border with the Republic of Moldova. The Danube flows into the Black Sea within Romania’s territory forming the Danube Delta, the second largest and best preserved delta in Europe, and also a biosphere reserve and a biodiversity World Heritage Site. Other major rivers are the Siret (596 km), the Olt (614 km), the Prut (742 km), the Someş (388 km), and the Mureş (761 km).
Lakes and lake complexes have a low share throughout Romania, occupying only 1.1% of total land area. The largest lake complex in size is Razelm-Sinoe (731 km²), located on the Black Sea seaside. Glacial lakes exist in the Făgăraş Mountains, a result of quaternary glaciation, of which the largest are: Lake Avrig (14,700 m²), Bâlea Lake (46,500 m²), Capra Lake (18,000 m²), etc. Other notable lakes are Lake Sfânta Ana, the only volcanic lake in Romania, and Red Lake, a natural dam lake, both situated in Harghita County.
