It is the beautiful river that makes Bihać the city it is. The magnificent Una runs straight through the middle of the city, covering Bihać in a fresh glow that few cities match up to. It might just be the most beautiful river in the country, a body of water so stunning that even the Romans were inclined to put it on a pedestal, referring to it as ‘The One’. Is there anything better than a sunny day on the Una? No, no there isn’t.
