The park is obviously centered on the Una River. All area whitewater rafting adventures start within the park boundaries. The two settlements inside the park, Kulen Vakuf and Martin Brod, are where a large majority of the infrastructure lies. A handful of B&Bs, cafés, raft launches, and restaurants are the extent of the park’s human touches. The falls at Martin Brod and Štrbački Buk rank among the best of waterfalls in southeastern Europe. The color and purity of the Una River is breathtaking. This aquatic lifeline is completely engulfed in a deep-green forest of vegetation, including many rare and endemic species.
