Štrbački buk, Waterfall and cliff in Una National Park, Bosnia and Herzegovina
Štrbački buk is a 25-metre-high waterfall on the Una River at an altitude of 296 metres, on the border of Croatia and Bosnia and Herzegovina. It is the highest waterfall in Una National Park and lies south of Doljani and Bihać and north of Donji Štrbci and Donji Lapac.
Štrbački buk is a geomorphological natural monument formed by tectonic movement of the limestone terrain, which the Una River then cut through. The river marks the border between Croatia and Bosnia and Herzegovina at this point, and the falls lie within Una National Park.
The waterfall draws locals and visitors who gather here to experience the river's power and natural surroundings. People use the area for swimming, picnicking, and enjoying time outdoors with family and friends.
The site is accessible by car followed by a walk through the forest to reach the waterfall. Wear sturdy shoes as the paths near the water can become slippery, especially during wet weather or when water levels are high.
Štrbački buk is the highest waterfall in Una National Park, dropping about 25 m; a Croatian source gives 24 m at an elevation of 294 m. Lonely Planet called it "a strong contender for the title of the nation's most impressive waterfall". The Croatian sources describe it as a geomorphological monument of nature formed by tectonic movement.
