In 60 seconds
Flowing through the northwestern corner of Bosnia and Herzegovina along the border with Croatia, the Una River is celebrated as one of the purest, most visually arresting rivers on the European continent—its Latin name meaning 'The Only One'. At its heart lies Una National Park, a protected wilderness sanctuary of travertine canyon walls, ancient riverside beech forests, and thunderous waterfalls. The park's undisputed natural masterpiece is Štrbački Buk, a monumental 24.5-metre series of multi-tiered travertine cascades churning the electric-emerald current into white foam. The regional hub of Bihać offers historic riverside fortresses like Captain's Tower, vibrant waterfront restaurants, and access to Europe's premier wild-river rafting.
