National Park “Una” is spread through the valley of the upper stream of the river Una as well as through the valley of the river Unac, right tributary of Una, all the way to the river Krka in the west. This area represents a unique natural complex in this part of Europe, very valuable for the conservation of the total landscape and biodiversity, especially because of:
– Position on the border of three climate areas;
– Karst formations and hydrology, which are unique in European terms, together with the basin of Korana and Krka;
– Landforms that created one of the few natural routes to the Adriatic Sea;
– Mosaic of habitats, high diversity of plant and animal species, and the presence of relict and endemic species;

The Štrbački buk is with 24.5 meters the highest and most spectacular waterfall of NP Una. The waterfall can actually be seen from two sides: from the Bosnian and Herzegovinian side it is at Una National Park, on the Croatian side it is Una Mamea Park. The Bosnian side is by far the most enjoyable with decent paths, excellent view points and facilities.
