Štrbački buk
Štrbački buk is a magnificent waterfall on the Una River and one of the most panoramic natural landmarks in Bosnia and Herzegovina. Located precisely on the border with Croatia within the Una National Park, it sits about 20 kilometers south of the city of Bihać. The waterfall is a complex of cascades, with the primary drop reaching an impressive height of 24 meters, making it the highest in the national park. It was formed over millennia by the deposition of tufa, which created massive travertine barriers in the riverbed. The area is well-equipped with wooden walkways and observation decks that offer safe and spectacular views of the rushing white water against the lush green landscape. Štrbački buk is also a major hub for extreme water sports, serving as the starting point for the most challenging rafting sections on the river. Its ecological significance is high, as the turbulent waters are highly oxygenated, supporting a unique aquatic ecosystem characterized by rare mosses and fish species.
