The river is the main watercourse of Banja Luka and before Banja Luka. With its blue-green color, it's one of the most beautiful rivers in Bosnia and Herzegovina.
The Sava is 990 kilometres (615 miles) long, including the 45-kilometre (28 mi) Sava Dolinkaheadwater rising in Zelenci, Slovenia. It is the largest tributary of the Danube by volume of water, and the second-largest after the Tisza in terms of catchment area (97713km²) and length. It drains a significant portion of the Dinaric Alps region, through the major tributaries of Drina, Bosna, Kupa, Una, Vrbas, Lonja, Kolubara, Bosut and Krka. The Sava is one of the longest rivers in Europe and among the longest tributaries of another river.
Banja Luka (Serbian Cyrillic: Бања Лука, pronounced[bǎɲalǔːka]) or Banjaluka (Serbian Cyrillic: Бањалука, pronounced[baɲalǔːka]) is the second largest city in Bosnia and Herzegovina, and the most populous, economic, political, and administrative center of Republika Srpska. Banja Luka is the traditional centre of the densely forested Bosanska Krajina region of northwestern Bosnia & Herzegovina. According to the 2013 census, the city proper has a population of 138,963, while its administrative area comprises a total of 185,042 inhabitants.
The city is home to the University of Banja Luka and the University Clinical Center of the Republika Srpska, as well as numerous entities and state institutions for the Republika Srpska and Bosnia and Herzegovina, respectively. The city is located on the Vrbas river. Banja Luka was designated a European city of Sport in 2018.
The Bosna (Serbian Cyrillic: Босна, pronounced[bɔ̂sna]) is the third longest river in Bosnia and Herzegovina, and is considered one of the country's three major internal rivers, along with the Neretva and the Vrbas. The other three major rivers of Bosnia and Herzegovina are the Una, to the northwest; the Sava, to the north, and the Drina, to the east. This river is the namesake of Bosnia. The river Bosna flows for 282 kilometers (175 mi).
The river is possibly mentioned for the first time during the 1st century AD by Roman historian Marcus Velleius Paterculus under the name Bathinus flumen. Another basic source that is associated with the hydronym Bathinus is the Salonitan inscription of the governor of Dalmatia, Publius Cornelius Dolabella, where it is said that the Bathinum river divides the Breuci from the Osseriates. Another name could also have been Basante.
Vranica (Serbian Cyrillic: Враница) is a mountain range in the Dinaric Alps of central Bosnia and Herzegovina, located between the town of Gornji Vakuf in the west and the town of Fojnica in the east, within the territory of the Federation. The highest peak is Nadkrstac at 2,110 metres (6,920 ft). Geologically, the Vranica range is part of the Dinaric Alps and formed largely of secondary and tertiary sedimentary rock, mostly limestone. Notable peaks are Nadkrstac (2110 m), Locika (2106 m), Rosinj (2059 m) and Scit (1949 m). Thick shrubs of Pinus Mugo replace mixed forest—mostly beech—above 1,400 m (4,600 ft). The typical karst characteristics of the nearby Herzegovina mountains is relatively absent in Vranica, which has relatively abundant water sources. Streams that source from these mountains are the Dragača in the east, the Vrbas in the west.
