Kostelski Buk

Kostela & Kostelski Buk are a scenic and easily accessible natural attraction located on the Una River near Bihać in northwestern Bosnia and Herzegovina.

Kostelski Buk is a beautiful series of smaller waterfalls and rapids where the Una River flows over limestone formations, creating turquoise pools and white cascades. The area is known for its calm, picturesque atmosphere and is less crowded than the more famous Štrbački Buk, making it ideal for a relaxed visit.

Just nearby lies Kostela, a historic village featuring the remains of an old fortress that once guarded the river valley. The combination of natural beauty and historical ruins gives the area a special charm, blending culture and landscape in one stop.

Visitors can enjoy riverside walking paths, photography spots, and a restaurant right by the water, where the sound of the Una flows alongside a peaceful countryside setting. Kostela & Kostelski Buk are a perfect short stop for travelers exploring the Una region between Bihać and Cazin.
