The Iskar (Bulgarian: Искър, pronounced [ˈiskɐr]; Latin: Oescus) 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, the Iskar flows in a northern direction until its confluence with the Danube. 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. As it crosses the mountains, its water course turns in a 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.
Its watershed drains 8,617 km in the provinces of Sofia, Sofia City, Vratsa, Lovech and Pleven. The Iskar flows through nine towns and numerous villages. The Iskar river basin is home to more than 50 species of fish, including Cottus haemusi that is endemic to the upper Iskar and Vit drainages.
Transport in Bulgaria is dominated by road transport. As of 2024, the country had 879 kilometers of highways and another 117 km under construction. The total length of the network is almost 40,000 km, divided nearly in half between the national and the municipal road network. In addition, there are 57,000 km of streets. Buses play a significant role in long-distance public transport, coaches are operated by private companies. The capital Sofia has three major national bus terminals, the Central, the Western and the Southern Terminals.
The railway system is well-developed but the average speed is comparatively low; however, upgrading projects are underway. The Bulgarian State Railways (BDŽ) is the national railway company since 1879, but private freight operators are also present. The total length of the network reached 4,029 km, of which 995 km are doubled and 3001 km are electrified. With 74.4% of the railway network electrified, Bulgaria ranks fifth in Europe and among the first in the world. The Sofia Metro has four lines as of 2023.
