Una National Park, established in 2008, is located in the northwestern part of Bosnia and Herzegovina near the city of Bihać. The park covers the upper reaches of the Una and Unac rivers, preserving a unique fluvial landscape characterized by dramatic waterfalls and deep canyons. The most famous landmark within the park is Štrbački buk, a 24.5-meter high waterfall formed by tectonic activity and limestone deposits. The region is celebrated for its extraordinary biodiversity, including numerous endemic plant species and a rich aquatic fauna that makes it a world-class destination for fly fishing. Historically, the Una valley has been inhabited since ancient times, with ruins of Roman settlements and medieval fortresses like Ostrovica dotting the landscape. The park plays a crucial role in regional sustainable tourism, offering activities such as rafting, hiking, and nature photography while maintaining strict conservation standards. The pristine quality of the water, known for its distinct emerald green hue, is a primary focus of the park's environmental protection efforts.
