Getting There

Una National Park is most easily accessed through the town of Bihać, which serves as the main gateway to the park. From Sarajevo, drive northwest for approximately 300km (4 hours) via the A1 highway and local roads. International visitors often fly into Zagreb, Croatia (150km away) or Ljubljana, Slovenia (200km away) and drive to the park. Regular bus services connect Bihać to major Bosnian cities, though having a car provides much greater flexibility for exploring the park's various sections and trailheads.

Getting Around

A personal vehicle is highly recommended for exploring Una National Park, as public transportation within the park is limited. The main park road follows the Una River and provides access to most major attractions and trailheads. Local taxi services and tour operators in Bihać offer transportation to popular spots like Štrbački Buk waterfall. Many visitors combine walking, hiking, and water-based transportation via rafts or kayaks to fully experience the park. Bicycle rentals are available in Bihać for those preferring eco-friendly exploration of the flatter riverside areas.
