Bihać & the Una.
A journey worth taking.
Enter Bosnia and Herzegovina through Izačić and discover emerald water, medieval fortresses, welcoming rural estates and unforgettable outdoor adventures around Bihać.
Cross the border. Enter a landscape shaped by the Una.
Izačić lies on the main western approach to Bihać, close to Croatia and the European Union. It is more than a place to pass through: it is a practical starting point for exploring the Una–Sana region, where river islands, waterfalls, mountain scenery, historic towns and local hospitality are all within reach.
Three places that reveal the soul of the Una
Waterfalls, quiet river settlements and a landscape that feels wonderfully untouched.

A remarkable site that requires real caution
Željava straddles an international border and parts of the wider area remain dangerous. The abandoned tunnels and structures are not a managed tourist attraction.
Plan lightly. Travel responsibly.
Distances can look short on a map, but rural roads, weather and border traffic may affect travel time.
Check current information
Confirm opening hours, ticket prices, road access and activity availability directly with official sites or local operators before travelling.
Use qualified guides
For rafting, kayaking and quad tours, use established providers, follow safety instructions and choose a route suited to your experience.
Leave the Una as you found it
Stay on marked routes, take waste with you, protect wildlife and respect local homes, farmland and protected areas.
