The Danubian Plain (Bulgarian : Дунавска равнина, romanized: Dunavska ravnina) constitutes the northern part of Bulgaria, situated north of the Balkan Mountains and south of the Danube. Its western border is the Timok River and to the east it borders the Black Sea. The plain has an area of 31,523 square kilometres (12,171 sq mi). It is about 500 kilometres (310 mi) long and 20 to 120 kilometres (12 to 75 mi) wide.
The Danubian Plain is contiguous with the Wallachian Plain (forming the Lower Danubian Plain), but the relief is hilly, featuring numerous plateaux and river valleys. The climate is markedly temperate continental with a weak Black Sea influence in the east. Precipitation is on average 450–650 mm a year. Important rivers include the Danube, the Iskar, the Yantra, the Osam, the Vit, the Rusenski Lom, the Ogosta and the Lom.
Among the major cities of the region are Varna, Rousse, Pleven, Dobrich, Shumen, Veliko Tarnovo, Vratsa, Vidin, Montana, Silistra, Targovishte, Razgrad, Svishtov and Lom.
In the Danubian Plain there is a wide variety of minerals, such as:
Bulgaria is a country situated in Southeast Europe and occupies the eastern quarter of the Balkan peninsula, being the largest country within its geographic boundaries. It is bordering Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. The northern border with Romania follows the river Danube until the city of Silistra. The land area of Bulgaria is 110,994 square kilometres (42,855 sq mi), slightly larger than that of Iceland or the U.S. state of Tennessee. Considering its relatively small size, Bulgaria has a great variety of topographical features. Even within small parts of the country, the land may be divided into plains, plateaus, hills, mountains, basins, gorges, and deep river valleys. The geographic center of Bulgaria is located in Uzana.
With an area of 238,397 km2 (92,046 sq mi), Romania is the twelfth-largest country in Europe. Located in Southeastern Europe, bordering on the Black Sea, the country is halfway between the equator and the North Pole and equidistant from the westernmost part of Europe—the Atlantic Coast—and the most easterly—the Ural Mountains. Romania has 3,195 kilometres (1,985 mi) of border. Republic of Moldova and Ukraine lie to the east, Bulgaria lies to the south, and Serbia and Hungary to the west. In the southeast, 245 kilometres (152 mi) of sea coastline provide an important outlet to the Black Sea and the Atlantic Ocean.
Teleorman County is a county (județ) of Romania on the border with Bulgaria, in the historical region Muntenia, with its capital city at Alexandria.
Pleven Province is a province located in central northern Bulgaria, bordering the Danube river, Romania and the Bulgarian provinces of Vratsa, Veliko Tarnovo and Lovech. It is divided into 11 subdivisions, called municipalities, that embrace a territory of 4,653.32 km2 (1,796.66 sq mi) with a population, as of February 2011, of 269 752 inhabitants. The province's capital is the city of Pleven.
The East European Plain is a vast interior plain extending east of the North European Plain, and comprising several plateaus stretching roughly from 25 degrees longitude eastward. It includes the westernmost Volhynian-Podolian Upland, the Central Russian Upland, and on the eastern border, encompasses the Volga Upland. The plain includes also a series of major river basins such as the Dnepr Basin, the Oka–Don Lowland, and the Volga Basin. Along the southernmost point of the East European Plain are the Caucasus and Crimean mountain ranges. Together with the North European Plain, and covering the Baltics, Moldova, south-eastern Romania, and its most southern expansion – the Danubian Plain in Northern Bulgaria,, it constitutes the majority of the Great European Plain, the greatest mountain-free part of the European landscape.
Europe is traditionally defined as one of seven continents. Physiographically, it is the northwestern peninsula of the larger landmass known as Eurasia ; Asia occupies the eastern bulk of this continuous landmass and all share a common continental shelf. Europe's eastern frontier is delineated by the Ural Mountains in Russia, which is the largest country by land area in the continent. The southeast boundary with Asia is not universally defined, but the modern definition is generally the Ural River or, less commonly, the Emba River. The boundary continues to the Caspian Sea, the crest of the Caucasus Mountains, and on to the Black Sea. The Bosporus, the Sea of Marmara, and the Dardanelles conclude the Asian boundary. The Mediterranean Sea to the south separates Europe from Africa. The western boundary is the Atlantic Ocean. Iceland, though on the Mid-Atlantic Ridge and nearer to Greenland than Mainland Europe, is generally included in Europe for cultural reasons and because it is over twice as close to mainland Europe as mainland North America. There is ongoing debate on where the geographical centre of Europe falls.
The Iskar is a right tributary of the Danube. With a length of 368 km it is the longest river that runs entirely within Bulgaria. Originating as three forks in Balkan's highest mountain range Rila, it flows in northern direction until its confluence with the Danube River. As it flows northwards it fuels the largest artificial lake in the country, the Iskar Reservoir, forms the divide between the Vitosha and Plana Mountains in the west and the Sredna Gora mountain range in the east before entering the Sofia Valley, which contains the nation's capital Sofia. From there the Iskar runs through the Balkan Mountains forming the spectacular 84 km long Iskar Gorge and as it crosses the mountains its water course turns in north-eastern direction at Lakatnik. North of the Balkan Mountains the river crosses the Danubian Plain and finally flows into the Danube between the villages of Baykal and Gigen. Geologically, Iskar is the oldest river in the Balkan Peninsula.
The Romanian Plain is located in southern Romania and the easternmost tip of Serbia, where it is known as the Wallachian Plain. Part of the historical region of Wallachia, it is bordered by the Danube River in the east, south and west, and by the Getic Plateau in the north. Bucharest, the capital of Romania, is located in the central part of the Romanian Plain. It is contiguous to the south with the Danubian Plain, in Bulgaria. This area is also sometimes referred to as the Danubian Plain(Câmpia Dunării) in Romanian, though this designation is not specific, because the Danube flows through a number of plains along its course, such as the Hungarian Plain as well as the Bavarian Lowland, also called Danubian plain.
The Rusenski Lom is a river in northeastern Bulgaria, the last major right tributary of the Danube. It is formed by the rivers Beli Lom and Cherni Lom, the former taking its source south of Razgrad and the latter southeast of Popovo.
In the Middle Ages the Bulgarian Empire controlled vast areas to the north of the river Danube from its establishment in 681 to its fragmentation in 1371-1422. These lands were called by contemporary Byzantine historians Bulgaria across the Danube, or Transdanubian Bulgaria. Original information for the centuries-old Bulgarian rule there is scarce as the archives of the Bulgarian rulers were destroyed and little is mentioned for this area in Byzantine or Hungarian manuscripts.

Northern Bulgaria, also called Moesia is the northern half of Bulgaria, located to the north of the main ridge of the Balkan Mountains which conventionally separates the country into a northern and a southern part. Besides the Balkan Mountains, Northern Bulgaria borders the Timok River and Serbia to the west, the Danube River and Romania to the north and the Bulgarian Black Sea Coast to the east.
Zlatiya is a small geographic region in Northern Bulgaria. Zlatiya is a low asymmetrical plateau in the northwestern part of the country, a subregion of the Danubian Plain. It lies between three rivers: the Tsibritsa to the west, the Ogosta to the east and the Danube to the north. The plateau's elevation is around 100–150 metres above mean sea level, the highest point reaching 176 m near the Danube. The soil is a fertile chernozem; no rivers cross the plateau, but by heavy rainfall the ravines are drained away to the east by the Ogosta river and ultimately into the Danube. Zlatiya has been an Important Bird Area since 2005 and has been included in the EU's Natura 2000 ecological network. The protected area covers 434.987 square kilometres.
The Tsibritsa is a river in the western Danubian Plain of northern Bulgaria and a right tributary of the Danube.

The Shumen Plateau Nature Park is located in the Shumen Plateau of the northern province of Shumen of Bulgaria, the highest plateau of the Danubian Plain. The Park encloses the Bukaka Reserve Forest, which is known for indigenous Fagus sylvatica Fagus sylvaticamoesiaca forest. This Park was declared a National Park in 1980 and a Nature Park in 2003 to conserve its ecosystems and floral and faunal biodiversity, and to preserve its tableland landscape together with many tourist sites such as the Shumen fortress, the Monument to 1300 Years of Bulgaria, cave monasteries, and surface and underground karst caves. The park has the first thematic educational trail in the Karst Nature Park, constructed as part of a project titled "Natural Park of Shumen Plateau" with funds provided by the EU Cohesion Fund and the Republic of Bulgaria; the trail is integral to the Operational Program "Environment 2007–2013".
