Bosnia and Herzegovina is located in the western part of the Balkan Peninsula and is characterized in large parts by a forested low mountain range, with the highest mountains reaching heights of almost 2400 meters above sea level. Part of the mountainous area, especially in the western parts of the country and Herzegovina, is karstified. The surface water that accumulates here does not reach the large river systems, but seeps away for the most part. In the south, as well as in the Sava lowlands to the north, there are also flatter regions that are used for agriculture. Also in the south is the 20-kilometre-long Adriatic coast near Neum.

Borders
Bosnia and Herzegovina has a total of 1538 kilometres of external border with its three neighbouring states. Of these
- 932 kilometres to Croatia, which surrounds the country in an arc to the north and west; this border is part of the EU's external border,
- 357 kilometres to Serbia in the east and
- 249 kilometers to Montenegro in the southeast.
The only access to the sea is the Neum Corridor, a strip of land that interrupts the Croatian territory over a width of about 7.5 kilometres. The southern part of Croatia with the city of Dubrovnik can so far only be reached by land via the territory of Bosnia-Herzegovina or from the east from Montenegro. From 2022, the Pelješac Bridge will create a road connection between the two parts of Croatia, bypassing the Neum Corridor.
Due to its central location, Bosnia and Herzegovina is the only former Yugoslav republic surrounded exclusively by other former republics.
Geomorphology
The highest areas of the country are located in the southeast, on the historical border between Bosnia and Herzegovina. The peak of the Maglić massif, located south of Foča on the Montenegrin border, is the highest point at 2386 metres. The rest of the country is mainly characterized by low mountainous landscape.
Climate
Bosnia and Herzegovina is located in the transition area between Mediterranean and continental climate. Winters can be very cold and temperatures down to -20 degrees Celsius are not uncommon. Summers are mainly very hot and dry due to the location of the country.
Landscape zones
The country can be divided into three landscape zones according to the climatic zones.
The Pannonian Plain
On its northern border, Bosnia and Herzegovina is part of the Pannonian Plain, which extends here in the area of the Sava lowlands.
The Dinaric mountain region
The Dinaric mountain region, also called the "Bosnian Dinarides", stretches from the southeast of the country across the central region to the northwest. This landscape is characterized by numerous mountains, which are less karstified, but covered with forest surfaces. Cities such as Sarajevo, Zenica and Bihać, among others, are located in this landscape zone. These areas are usually very warm in summer, with temperatures of up to 35 °C, and cold in winter, when the temperature can also drop to -15 °C and a lot of snow can fall.
The Adriatic coastal region
Herzegovina is mostly part of the Adriatic coastal region. Characterized by Mediterranean influences, Herzegovina consists mainly of karst or karstified mountain ranges. The Neretva River, which flows from northeastern Herzegovina through Mostar towards the Adriatic coast, is the largest and best known of this region.
Waters
The country's main rivers are the Sava and Drina, which border Bosnia and Herzegovina to the north and east, and the Bosna, which rises in the interior and flows into the Sava. Almost the entire territory of Bosnia belongs to the Sava or Black Sea catchment area, while the rivers of Herzegovina drain - partly underground - into the Adriatic Sea.
The valleys of Bosnia's major rivers extend almost exclusively in a north-south direction, which is significant for the country's settlement and transport history. The larger rivers include the Una and Sana, the Vrbas and the Neretva. Apart from the Sava River on the border with Croatia, no river in Bosnia and Herzegovina is navigable.
Bosnia and Herzegovina is located in the Blue Heart of Europe.
Bosnia and Herzegovina has few significant lakes. Most of the large still waters have been artificially dammed. Large reservoirs exist on Drina (e.g. Lake Zvornik), Neretva (Jablaničko jezero), Vrbas and Trebišnjica (Bilećko jezero). Modračko jezero near Lukavac in the canton of Tuzla is also a reservoir.

Land use
Only just under one fifth of the country's area is suitable for arable farming. This land is mainly located along the Sava River, on the lower reaches of the Neretva River and in the Poljen of Herzegovina.
