Bosnia and Herzegovina’s Una National Park is drawing attention from adventure travellers through a landscape shaped by the Una and Unac rivers, waterfalls, karst formations, forests and mountain trails in the country’s far west. The park sits near the Croatian border and covers 19,800 hectares, with Bihać serving as its closest major urban centre.
For visitors, the attraction is easy to understand once the rivers come into view. Rapids, cascades, waterfalls and clear mountain waterways create a setting where rafting, kayaking, canoeing, hiking and cycling can form the core of a multi-day outdoor itinerary.
Una National Park Sits at the Heart of Dinaric Travel
Una National Park became a protected national park in 2008 and is part of the wider Dinaric protected-area network. Parks Dinarides identifies the park as an important natural area where the Una and Unac rivers run through canyon landscapes and karst terrain.
The park’s position also makes it relevant to travellers combining Bosnia and Herzegovina with neighbouring Croatia. Bihać is approximately 150 kilometres from Zagreb, according to Parks Dinarides, while Sarajevo is around 310 kilometres away by road.
That location allows visitors to approach Una as part of a wider regional road journey rather than treating the national park as an isolated destination.
Waterfalls Lead the Visitor Experience
Water is central to tourism across the park. Martin Brod and Štrbački buk are among its best-known waterfall attractions, while Troslap adds another series of cascades along the Una.
Štrbački buk is particularly important for outdoor tourism because the surrounding area supports rafting and other activities. The national park’s current visitor information lists rafting, kayaking and canoeing sections between Štrbački buk and Lohovo, as well as between Martin Brod and Kulen Vakuf.
Travellers planning water-based activities should note that park admission or waterway access fees do not necessarily include equipment or activity services. Organised operators may therefore need to be contacted separately before a trip.
Hiking Routes Add a Mountain Dimension
The rivers are only one part of the experience. Una National Park also offers hiking, canyon walking and mountain biking, allowing visitors to explore landscapes away from the main waterfalls and waterways.
The combination creates several ways to structure a visit. A traveller could spend one day around waterfalls and river activities, then move into hiking areas or nearby villages for a slower exploration of the surrounding landscape.
The park’s karst formations also contribute to its distinctive geography. Travellers interested in nature photography can encounter river canyons, travertine barriers, islands, caves and cascades across the protected landscape.
Martin Brod and Kulen Vakuf Extend the Journey
Martin Brod provides one of the main visitor areas within Una National Park. Its waterfalls and connection with the Unac River make it a natural stop for travellers exploring the park’s aquatic landscape.
Kulen Vakuf offers another useful base for exploring the surrounding area, particularly for visitors interested in combining river activities with village and cultural experiences. The park’s designated water routes include the Martin Brod to Kulen Vakuf section for rafting, kayaking and canoeing.
These locations can be incorporated into a longer western Bosnia itinerary, particularly for travellers moving between Bihać, the national park and the Croatian border.
Wildlife and Biodiversity Add Depth to the Visit
Una National Park is also significant for biodiversity. Parks Dinarides records around 1,900 plant species in the area, including medicinal, edible and aromatic species, alongside numerous fish, amphibian, reptile, bird and mammal species.
The park includes habitats supporting species such as otters, bears, wolves and lynx, although wildlife encounters in a protected natural environment are never guaranteed. Birdwatching and nature photography can therefore complement hiking and river activities without becoming dependent on seeing particular animals.
For visitors, the biodiversity reinforces the need to stay on designated routes and follow national park rules, particularly around waterways and sensitive natural areas.
Fishing and Water Activities
Fishing is another established recreational activity in the park. Official park material identifies fishing areas along sections of the Una and Unac, while regulations govern permitted methods and designated fishing zones.
Visitors interested in fishing should arrange the appropriate permits and check current rules before travelling. Regulations can differ according to the river section, season and activity.
For travellers focused on rafting, kayaking or canoeing, the same preparation applies. River conditions can vary, and equipment, guides and access arrangements should be confirmed before departure.
Getting to Una National Park
Bihać is the closest major centre for visitors heading to Una National Park. The city is connected by road with Sarajevo and Zagreb, making the destination practical for travellers building a cross-border itinerary through western Bosnia and Herzegovina and neighbouring Croatia.
Road travel is particularly useful because attractions within the park are spread across different visitor zones. Travellers can plan separate stops around Štrbački buk, Martin Brod, Kulen Vakuf and other natural attractions rather than relying on a single central sightseeing area.
Visitors should check road conditions, park access arrangements and opening information before setting out, particularly when travelling outside the main summer period.
Una Fits the Wider Dinaric Adventure Network
Una National Park forms part of the wider Dinaric network, which links protected areas across several countries in southeastern Europe. Parks Dinarides currently lists more than 100 protected areas across Albania, Bosnia and Herzegovina, Montenegro, Croatia, Kosovo, North Macedonia, Slovenia and Serbia.
For adventure travellers, this creates opportunities to combine Una with other mountain and protected-area destinations during a longer Balkan journey.
The result is a destination where rivers, waterfalls, villages, forests and mountain routes can be explored within the same trip. Una National Park therefore offers a practical starting point for travellers looking to experience western Bosnia and Herzegovina through outdoor activities and Dinaric landscapes.
