Student center, Mostar

Amphitheater “Sokrat“ at Faculty in Philosophy


Mostar is located at the place that naturally connects the Adriatic coast and the Bosnian hinterland. The city is characterised by a charming combination of karst topography and an abundance of watercourses. Various historical moments have left their mark on the city, shaping Mostar in a way that has won the affection of visitors from New Zealand to Canada and from Chile to Japan.

Mostar lies on the river Neretva and is the fifth largest city in the country. Mostar was named after the bridge keepers (mostari) who guarded the Stari Most (Old Bridge) over the Neretva during the Ottoman era.

The Old Bridge is undoubtedly the highlight of a visit to Mostar. Stroll across it, take selfies with it and enjoy the view of the old town from the bridge. Mostar has more to offer than just a beautiful, fairytale bridge. The stone streets of the old town are almost as charming as the bridge itself

In the last ten years, Mostar has been included in most tourist itineraries. It would be difficult to find a reputable tour operator that covers the Balkans and does not offer Mostar in its travel programme. Mostar is located halfway between Sarajevo (BiH), Dubrovnik and Split (Croatia). Only 130 km and about 2h – 2h 15min easy and comfortable drive will bring you to Mostar from any of these frequently visited and very popular destinations.

There are numerous places in the surroundings of Mostar that are suitable for various types of outdoor activities. Regardless of the level of athleticism and physical fitness, the nature of offer offers something for everyone.

On Fortica Hill, a part of Velež Mountain, there is an adventure park that offers such diverse activities as ziplining, climbing, abseiling (rappelling), via ferrata, mountain biking and mountain safari.

In the mountains of Velež, Čvrsnica, Čabulja and Prenj, there are numerous hiking trails with different levels of difficulty. For those who prefer an easy hike, the Hum hill or Mostarska bijela are great options.

Meeting Location: Student Center, Mostar

The student center in Mostar is the most modern student center in the region. The center has 179 student rooms, each of which has internet and cable connection, heating and hot water as well as a private bathroom. There is a Wi-Fi network in all common areas. The center has a large room where meals are served.

The Sokrat amphitheater has about 140-150 seats and lectures are offered throughout the day.

Exercise area: Prosječenica cave, Vrelo Bune, Crno vrelo and Crno oko

The Prosječenica Cave is 347 meters long and 42 meters deep. The first 166 meters of the cave are easily accessible and until recently this was the only known part. After 166 meters of the cave channel, there is a narrowing of 4 meters, followed by a continuation of the channel with an average width of 4-5 meters, a height of 3-5 meters and a length of 181 meters. The constriction is difficult to pass and only possible for cavers of smaller stature. However, to protect the cave and the bats living in it and to prevent the cave decoration from breaking off, it is not advisable to widen the constriction. Even after the narrowing, the cave is richly decorated with numerous stalactites, stalagmites, ointments and lakes. Near the end of the cave there is a mural stalagnate. This is followed by a high and spacious hall from which no further passage could be observed. The only way to continue the exploration is to technically climb the high chimney at the end of the cave.

The Buna Spring is a natural and architectural ensemble at the source of the Buna River near Blagaj, southeast of Mostar, Bosnia and Herzegovina. It is a strong karst spring that emerges from a huge karst cavern under a high vertical cliff. This region is characterised by the diversity of its surface and underground hydrography. The Buna spring is one of the largest springs in Europe, producing approximately 30 m3/s of extremely cold and clean water.

The Black Eye Cave is located in the village of Grabovica, north of Mostar. A completely new canal was found, which ends after about 200 meters in a dry gallery with a 4 meter high waterfall, at the top of which is a small lake. From this lake, the canal leads further into the depths, so further research is planned.

The cave of the Black Spring is located in Lake Salakovac. Today, the entrance to the cave itself lies at a depth of 8-10 meters, depending on the height of the lake. The fall into the shaft itself is at an angle of 40˚ to 45˚, and the view is unreal. The opening through which the blue of the lake breaks through is monitored and traced to a depth of 25 meters. The depth of the black spring is about 80 meters.

Geology and geomorphology

The oldest rocks outcropping at or near the surface date from the Paleozoic era and the geological history of the region from the Precambrian is still poorly known. Complex assemblages of flysch, ophiolite, mélange and igneous plutons together with thick sedimentary units are a characteristic feature of the Dinaric Alps, also known as the Dinarides, which characterise much of the country’s landscape.

The first extensive research in Bosnia was carried out in the 1880s by Austrian and Croatian geologists, who published maps in the 1910s. During the Yugoslavian period after the Second World War, extensive mining led to further exploration. French geologists took a leading role in research from the late 1960s until the 1970s. Bosnia and Herzegovina has a long mining tradition dating back over 2000 years to Illyrian and Roman times. In particular, metals are mined from the Palaeozoic-Triassic nappe, which was formed during the Caledonian orogeny, the Hercynian orogeny and the Triassic. The rocks from the early Paleozoic contain metapelite and metapsammite as well as low quality hematite and magnetite. Siderite-ankerite deposits from The Carboniferous period, which are rich in iron, are traditionally mined in the Ljubija mines.

Bosnia and Herzegovina is largely mountainous. The Dinaric Alps dominate the western border with Croatia and numerous mountain ranges, including the Kozara, Vlašic, Plješevica, Grmeč, Cincar and Raduša, generally cross the country in a northwest-southeast direction. The highest peak, reaching 2,386 metres, is Maglić near the border with Montenegro. To the south and southwest is the Karst, a region of dry limestone plateaus containing caves, potholes and underground drains.

Bosnia and Herzegovina is known for its numerous caves and mines. Only in the vicinity of Mostar there is a whole series of pits, and one of the deepest is hidden there, Mala Dželalija. It was found that the depth of Mala Dželalija is 468 m, with an entrance height of 380 m, which makes it the second deepest pit in Bosnia and Herzegovina. Near Mostar there is a famous cave, Vjetrenica. It is the largest cave in Bosnia and Herzegovina. It is part of the Dinaric Alps mountain range, which is known for its karstic and speleological features. The cave is located in the Popovo field in Ravno, Eastern Herzegovina. Vjetrenica is the richest cave in the world in terms of underground biodiversity: of the more than two hundred different species recorded in it, almost a hundred are troglophilic, a large number of them are closely endemic, 15 are stenoendemic and about 37 were discovered and described in Vjetrenica for the first time.

Dahna is also one of the famous caves in Bosnia and Herzegovina. The Dahna Cave is located above the village of Omerovići, in the western part of the Duvno field. It has a small entrance (1x1m), hidden in a hornbeam forest, under a rock overgrown with moss. Beyond the entrance is a larger hall that is 20 m long, 6 to 7 m wide and 1 to 4 m high. From there, the path leads to a narrow, low channel, which has a very damp floor and is also covered with small stones. The total length of the cave channels is 1100 m.

Nevidna voda is the deepest cave explored to date in the Dinaric Massif and in Bosnia and Herzegovina. It is located 2 kilometers from the border between Bosnia and Herzegovina and the Republic of Croatia. The cave has two entrances that form the lowest part of the karst valley and are located about 1,200 meters above sea level. The research ended at a depth of -653 meters, where there is a lake deeper than 20 meters, consisting of two parts: the first with an elliptical surface of 40×15 meters and the second with a curved surface of 30×12 meters. The lakes are connected by a smaller, approximately 4 m long passage at water level and by a large 15×20 m opening in the ceiling of the last hall, so that the wall between them forms a natural bridge. The temperature of the lake is 8 °C. Submerged whitefish have been discovered in the lake, which indicates that the water in the lake comes from a depression on the edge of Livanjsko polje.


The most important rivers are the Sava, a tributary of the Danube, which forms the northern border with Croatia; the Bosna, the Vrbas and the Una, which flow northwards and flow into the Sava; the Drina, which flows northwards, forms part of the eastern border with Serbia and is also a tributary of the Sava; and the Neretva, which flows from the south-east but takes a sharp south-westerly course in the Karst region, flows through Croatia and flows into the Adriatic. Most of the rivers in the Karst region flow underground. Numerous glacial lakes dot the landscape. Bosnia and Herzegovina is also rich in natural springs, many of which are tapped for bottled mineral water or for the popular thermal baths.


Although Bosnia and Herzegovina is close to the Mediterranean, it is largely cut off from its climatic influences by the Dinaric Alps. The weather in the Bosnian region is similar to that of the southern Austrian highlands — generally mild, but it can get bitterly cold in winter. Herzegovina is more similar to the Croatian region of Dalmatia, where it can be oppressively hot in summer. In Mostar, which lies on the Neretva River, the coldest month is January with an average of 6 °C (42 °F) and the warmest month is July with an average of 26 °C (78 °F). Mostar has a relatively dry season from June to September. The rest of the year is humid, with the heaviest rainfall between October and January.
