Buna River – the hidden diamond below the cliff.

Let’s go and swim a little bit.

Did you know that the source of the Buna is one of the largest and most beautiful in Europe?!

This is the finest example of an underground karst river. The underground river flows out of a 200 meter cliff wall and forms the Buna River. There is no surprise that the Ottoman sultan was impressed, and ordered a tekke (tekija – Dervish monastery) to be built right next to it.

This house/monastery from 16th century  was built for the Dervish cults and is still one of the most mystical places in all of Bosnia and Herzegovina. It is open to visitors all year round and you can enjoy cold drinks, tea and tTurkish coffee in a beautiful garden overlooking the mouth of the Buna River.

Meanwhile Blagaj is a nearby village-town (kasaba) in the south-eastern region of the Mostar basin, in the Herzegovina-Neretva Canton of Bosnia and Herzegovina. Above the village towers the old Blagaj fort (Stjepan grad) which is the birthplace of Bosnian queen Katarina Kosača-Kotromanić. Unlike other fortifications serving as residences in Bosnia and Herzegovina, the Blagaj fortress is located on a natural level area above steep cliffs to the south, west and north. The walls have survived for much of their length to a height of 12 or 14 m. The interior defended area is relatively small, similar to that of the fortress in Jajce.


National Park Una is one of three national parks in Bosnia and Herzegovina. As National park was declared on 29 May 2008. The park encompasses the area of the canyon part of the river Una upstream from Lohovo, the canyon of the lower Unac river from its mouth upstream to the Una and the area between the two rivers.

National Park “Una” spreads from the valley of the river Una and Unac river valley, right tributary of the Una, to the river Krka on the west . This area is a unique natural complex in this part of Europe, is very valuable for the maintenance of overall landscape and biological diversity , especially due to:

  • position on the border of three climate areas
  • karst formations and hydrography, who together with basin Korana and Krka unique in European terms
  • landforms that have created one of the few natural pathways to the Adriatic Sea
  • mosaic of habitats, the great diversity of plant and animal species, and the presence of rare and endemic species

This area is also in the cultural and historical sense, an area that is rich legacy of archaeological sites and historical monuments, and the special position of the space on the transit route to the sea led him in the past under the influence of many cultures, from where come the rich archaeological sites, the remains of medieval fortresses and sacral objects of different religions and cultures. Special connection between the river Una (lat. Una = one first) and the local population is one of the significant features valuable for the preservation and protection of the space.
