The centrepiece of the Una National Park is the glorious Štrbački Buk, western BiH's finest set of waterfalls. The easiest access is 8km along a good, largely flat unpaved lane from Orašac on the Kulen Vakuf road via National Park Gate 3.
In dry conditions you could alternatively start from Gate 1 (Gorevac, 200m off the Bihać-Sarajevo road, 16km from Bihać) but that route uses 14km of woodland lanes that are rolling, very narrow and somewhat rocky (keep right then left at the only two turns en route).
