Sofia Province borders on three sides to the city of Sofia, but does not include it. Because of the large area and population of Bulgaria's capital, the city has been marked as a separate province. The district has a territory of 7 059 sq.km and has 273 240 inhabitants. It includes 22 municipalities: Anton, Botevgrad, Bozhurishte, Chavdar, Chelopech, Dolna Banya, Dragoman, Elin Pelin, Etropole, Ihtiman, Godech, Gorna Malina, Koprivshtitsa, Kostenets, Kostinbrod, Mirkovo, Pirdop, Pravets, Samokov, Slivnitsa, Svoge and Zlatitsa. The landscape has mainly mountainous features. To the north are the southern slopes of the Balkan Mountains and to the south rises Rila with the highest mount on the Balkan peninsula - Mount Musala. There are also several smaller mountains and spacious valleys. One of the most prominent ski resorts in Bulgaria, Borovets, is located just a few kilometers from Samokov, in the heart of Rila Mountain. The region is a well-developed industrial area.

Elin Pelin, known previously as Novoseltsi, is situated in in the Sofia Valley, with the slopes of the Balkan Mountains to the north and Sredna Gora to the south-southeast, 24 km southeast of the capital. The area has been inhabited since antiquity. A Slavic settlement was founded in the Middle Ages and existed until the early Ottoman rule of Bulgaria. The town of Elin Pelin (then Novoseltsi) became a local cultural and trade centre during the Bulgarian National Revival. Its importance continued to grow with the construction of the Sofia–Septemvri) railway line and the establishment of the Izida ceramic factory, the first in the country. Despite everything, Elin Pelin is most popular for being the birth place of the noted Bulgarian writer Elin Pelin. It was renamed in his honour in 1950 and was proclaimed a town in 1960. Koprivshtitsa is one of the most popular historic town in Bulgaria. It lies on the Topolnitsa River among the Sredna Gora mountain. It was one of the centres of the April Uprising in 1876 and is known for the well-preserved authentic Bulgarian architecture and for its folk music festivals, making it a very popular tourist destination. Koprivshtitsa is one of the characteristic Bulgarian towns, still preserving the atmosphere of the Bulgarian National Revival period of the 19th century. The town is huddled in the mountain folds 111 km east of Sofia. It boasts 383 architectural monuments from the 18th century, most of which have been restored to their original appearance. It was here that the first shot of the April Uprising against the Ottoman occupation was fired in 1876. Another popular town in Sofia province is Samokov. Situated between the mountains of Rila and Vitosha, it is among the best areas for winter sports. Samokov and Borovets attract large number of tourists, both Bulgarian and foreign, all year round. Pravets (also Pravetz or Pravec) is located approximately 60 km from Sofia. Surrounded by mountains, with mild climate and rare winds, it is mostly associated with its (now closed) computer manufacturing plant and with the birthplace of Bulgaria's last communist president, Todor Zhivkov. The first microprocessor factory in Bulgaria was situated in Pravets. These computers, which were also the first in Bulgaria, were named Pravets-82 and will remain popular also for their yellow and black keyboards. Today, the town is famous for the branch of the City University of Seattle campus and two prestigious high schools.
