Bihac & the Una River

Bihać is a city in the far northwest of Bosnia and Herzegovina, on the banks of the Una River, about 225 km (straight-line) from Sarajevo, or roughly 311 km by road.

Bihać’s identity is closely tied to the Una River, one of the cleanest and most beautiful rivers in Europe, known for its emerald-green color and natural waterfalls. Bihać and the Una are famous across Europe for whitewater rafting, drawing visitors from across the continent to raft or swim in its clear waters.

One of Bihać’s most notable landmarks is Fethija Mosque, originally built in 1266 as a Gothic church dedicated to St. Anthony — making it the oldest Gothic building in the country. The Ottomans converted it into the city’s main mosque on the order of Hasan-Pasha Predojević, the Ottoman army commander and long-serving governor of Bihać, making it one of very few Gothic-style mosques anywhere in Europe.
