Balkana at a Glance

About Balkana

Balkana is a small lake and local recreation area in Republika Srpska, Bosnia and Herzegovina, located near the town of Mrkonjić Grad. The lake sits in a hilly, wooded landscape and is fed by small streams, forming a compact waterbody used for leisure and short walks.

The site is primarily visited by residents and regional visitors for day trips, swimming and picnics during warmer months. Facilities are modest and the setting is informal rather than a large developed resort.

The lake lies a short distance from Mrkonjić Grad in western Republika Srpska, set within rolling, forested hills of the region. The nearest urban centre is Mrkonjić Grad, with larger cities several dozen kilometres away.

  • Local recreation: Fed by two small mountain streams and set in wooded hills, the lake is a local recreational spot with walking paths and picnic areas.
