ABOUT THIS ITINERARY
Una National Park is a park built around a river, but its headline sights are spread across separated visitor zones rather than joined as one walkable centre. This itinerary threads the park into a two-day route that respects that geography: day one focuses on the western zone — the Štrbački Buk boardwalks and a guided raft descent of the Una — and day two moves upriver to the Martin Brod falls, the riverside town of Kulen Vakuf and the optional steep climb to Ostrovica Fortress above it. A self-guided waterfall and river-landscape circuit is offered as an alternative to rafting for visitors who prefer to stay on the bank, not as an additional promise that must be completed on the same day. The zones are geographically separated, this is not one continuous walking route, and a car or arranged transport is needed between them.
OVERVIEW
The route at a glance
Day one begins at Štrbački Buk, the park’s thundering multi-tiered cascade on the Bosnia–Croatia border, where a network of boardwalks and viewing platforms climbs the gorge beside the falls. From there a half-day raft descent — arranged with a qualified or licensed operator based in Bihać or the park — puts you onto the same river from inside the current. Rafting should only be undertaken through a qualified or licensed provider and remains dependent on current weather, water conditions and participant suitability.
Day two moves upriver to the Martin Brod waterfalls, the gentler multi-step series of falls and pools beside the village of Martin Brod, then on to Kulen Vakuf, the quiet riverside town on the upper Una with its old stone bridge and the trailhead for Ostrovica. The day closes with the optional steep forest climb to Ostrovica Fortress, a demanding ascent that should only be attempted if conditions, daylight and visitor ability permit. Swimming should only be considered at officially marked or designated places while the relevant visitor zone is open; never swim close to or above waterfalls. Between every zone, a car or arranged transport is the practical way to move.
THE SCHEDULE
Day by day
Štrbački Buk and the Una raft descent
The western zone — the Štrbački Buk boardwalks and a guided half-day raft descent of the Una, with a self-guided waterfall circuit as a bank-side alternative to rafting.
- 09:00
Štrbački Buk
2–3 hoursBegin at Štrbački Buk, the park’s headline multi-tiered cascade on the Una at the Bosnia–Croatia border. A network of wooden boardwalks and viewing platforms climbs the gorge beside the falls, giving top, level and bottom viewpoints over the two-tiered drop and the deep emerald pool below. The boardwalks involve stairs and can be wet underfoot — wear shoes with grip. Entrance 3 at Ćelije is the official passenger-vehicle approach; check current park access information before departure.
- 13:30
Raft the Una river
Half dayIn the afternoon, take a guided half-day raft descent of the Una with a qualified or licensed operator based in Bihać or the park. The run mixes calm green stretches with rapids — bigger in spring, calmer and warmer in late summer — and puts you onto the river that everything else in the park is about. Rafting should only be undertaken through a qualified or licensed provider and remains dependent on current weather, water conditions and participant suitability; book ahead and confirm what a given trip includes before you go.
Optional stops
Explore the Una’s waterfalls and river landscapes (alternative to rafting)
Full day at a relaxed paceVisitors who prefer to stay on the bank can take the self-guided waterfall and river-landscape circuit instead of the raft descent. It links the Štrbački Buk boardwalks with the other zones by car and on foot, seeing the river’s water at your own pace rather than from a raft. This is an alternative to rafting, not an additional promise that must be completed on the same day — choose one or the other according to preference and conditions.
GETTING AROUND
A car or arranged transport is needed to reach Štrbački Buk from Bihać and to reach the raft operator’s put-in. Raft operators arrange transport to the put-in and back from the take-out. Wear shoes with grip for the boardwalks and quick-drying clothes for the raft.
EAT & DRINK
A couple of park restaurants sit near Štrbački Buk serving trout and ćevapi; otherwise Bihać offers the full range of choice. Carry water and snacks for the boardwalk circuit.
Martin Brod, Kulen Vakuf and Ostrovica
The upper park — the Martin Brod waterfalls, the riverside town of Kulen Vakuf and the optional steep climb to Ostrovica Fortress above it.
- 09:00
Martin Brod Waterfalls
2–3 hoursDrive upriver to Martin Brod, the village where the Unac meets the Una and the river builds a long, gentler series of travertine falls and pools — broader and lower than Štrbački Buk. Follow the riverside paths past the staircase of falls, with time to rest beside the water. The paths can be wet and uneven near the falls — wear shoes with grip. Swimming should only be considered at officially marked or designated places while the zone is open; never swim close to or above waterfalls.
- 12:30
Kulen Vakuf
1–2 hoursContinue upriver to Kulen Vakuf, the largest settlement in the upper park, where the Una runs wide, clear and green between wooded hills. See the old Ottoman single-arch stone bridge over the river and the upper valley panorama, and use the town as the practical base for the Ostrovica climb. A couple of restaurants and small accommodation options make it a good lunch stop.
- 14:30
Ostrovica Fortress (optional demanding climb)
2–3 hoursFrom the edge of Kulen Vakuf a forest trail climbs to the ruined medieval walls of Ostrovica Fortress on the hill above the town, giving the finest panorama over the upper Una valley in the park. Little survives of the castle itself, but the setting is the point. The climb is steep, uneven and rocky in places, and slippery after rain — it is an optional demanding ascent that should only be attempted if conditions, daylight and visitor ability permit. Wear grippy shoes, carry water, and avoid it in winter ice.
GETTING AROUND
A car or arranged transport is needed to move between Martin Brod, Kulen Vakuf and the Ostrovica trailhead — these are separated zones, not one continuous walk. Wear shoes with grip for the riverside paths and the Ostrovica climb.
EAT & DRINK
Martin Brod and Kulen Vakuf each have a couple of restaurants and guesthouses; otherwise carry water and snacks for the day. The upper park has limited facilities, so stock up before leaving Bihać.
SEASONAL NOTES
When to go
May to September gives the easiest conditions and the warmest water; spring brings the fullest, most dramatic waterfalls and the biggest raft rapids, while late summer is calmer, greener and better for swimming. Rafting should only be undertaken through a qualified or licensed provider and remains dependent on current weather, water conditions and participant suitability. Swimming should only be considered at officially marked or designated places while the relevant zone is open; never swim close to or above waterfalls. The Ostrovica climb is an optional demanding ascent — attempt it only if conditions, daylight and visitor ability permit, and avoid it in winter ice. Daylight varies widely through the year, so check the sunset time for the day you visit. Check current official park maps and access information before departure.
