The highest waterfall in Una National Park, on the Una river at the border between Bosnia and Herzegovina and Croatia, south of Bihać. It is about 25 metres high, and its water tumbles over successive steps of moss-covered tufa. Lonely Planet called it «a strong contender for the title of the nation's most impressive waterfall». Thick woodland surrounds it, and viewing platforms, boardwalks and footbridges look over it, from above and from close by. Una National Park was founded on 29 May 2008 to protect the Una and its tributaries, the Krka and the Unac, and at about 198 square kilometres it is the largest national park in Bosnia and Herzegovina. The Una is famous for its clear green water, waterfalls and rapids, which draw rafters. A full-day ticket for the Štrbački buk area is about 12 KM for adults and 8 KM for children aged 7 to 14, per the park's 2026 price list as reported by the local press. The entrance is reached by car from Bihać, and the falls are at their fullest in spring.
