Una National Park Essentials

Una National Park centers on the Una and Unac rivers, characterized by travertine barriers and the 24-meter Štrbački Buk waterfall. This selection includes the 15th-century Ostrovica fortress and the Ottoman-era Havala ruins near Kulen Vakuf. It also features the 16th-century Rmanj Monastery in Martin Brod and the Japodian Islands, a cluster of river islets connected by wooden bridges. These sites represent the park's blend of natural karst formations and historical defensive architecture spanning the medieval and Ottoman periods.
