Una River Rafting: Family-Friendly Whitewater in Una National Park

The Una River is the jewel of northwestern Bosnia. It rises in Srb and flows northwest through a broad valley before carving a series of waterfalls and gorges that eventually cross into Croatia. The section running through Una National Park near Bihać is the most accessible for rafting — a stretch of emerald-green water, travertine waterfalls, and limestone cliffs that rivals anything in the Western Balkans for sheer natural beauty. Crucially, the Una runs mostly Class II and III, making it the most family-appropriate rafting river in Bosnia and Herzegovina.

Why the Una Is Different from the Neretva

Both rivers offer world-class scenery and guided rafting, but they suit different groups. The Neretva near Konjic is faster, steeper, and regularly pushes into Class IV — it is the better choice if you want adrenaline and technical rapids. The Una is more continuous, more scenic, and lower in difficulty — a better fit for families, mixed-ability groups, or anyone who wants to spend as much time looking at the river as paddling through it.

The Una also has Štrbački buk: at roughly 25 m wide and 7 m high, it is the most spectacular waterfall in Bosnia. No rafting day on the Neretva has an equivalent centrepiece.

Rapid Difficulty and Section Overview

The main commercial rafting stretch follows the Una from Lohovo or Čedajna, downstream through Una National Park to Martin Brod or Bosanska Krupa — sections of 14–24 km depending on the operator and chosen start/end points.

Section	Distance	Class	Character
Lohovo to Martin Brod	~14 km	II–III	Past Štrbački buk, waterfalls, clear water
Martin Brod to Bosanska Krupa	~20 km	II	Wide valley, calm water, forest banks
Full Una canyon run	~24 km	II–III	Combines both sections above

Class III rapids on the Una are shorter and more technical than the Neretva’s sustained drops. The river’s characteristic colour — a vivid turquoise-green — comes from dissolved limestone, which also builds the travertine barriers that create the cascades throughout the national park.

Named Operators and Prices

Prices are approximate as of 2026.

Una Kiro Rafting (Kulen Vakuf) One of the most established operators on the Una, based near Kulen Vakuf in the heart of the national park. Full-day rafting (approx 18 km including Štrbački buk stop): from approximately €30–40 per person. Family half-day (shorter 10 km section): from €20–25 per person. Packages include wetsuit, buoyancy aid, helmet, paddle, and guide. Lunch at a riverside picnic area is typically included in the full-day price. Una Kiro also runs kayak and canoe hire by the hour for those who prefer to self-guide on the calmer sections.

Kanjon Una (Bihać area) Operates from Bihać and offers transfers to and from the park’s put-in points. Full-day rafting with national park entry: from approximately €35–45 per person. Private raft hire (up to 8 people): from approximately €240–280 per day. Kanjon Una specialises in multi-day Una packages combining rafting with camping at sites within the national park — a particularly popular option in July and August.

Una Rafting Club (Martin Brod) Smaller club-operated service based at Martin Brod village, which sits at the confluence of the Una and Unac rivers. Day trips covering the section from Kulen Vakuf to Martin Brod: from approximately €28–38 per person. The club also organises evening barbecue-and-swim sessions (non-rafting) at their riverside site in Martin Brod for approximately €12–15 per person including food.

Booking notes: The Una is less commercialised than the Neretva. Most operators respond via WhatsApp or email rather than online booking platforms. Some offer pick-up from Bihać town; check when booking. In high season (late July–August) spaces can fill quickly on weekends when families from Sarajevo and the Croatian coast visit the park.

Combination with Štrbački Buk Waterfall

Štrbački buk is located on the Una River approximately 8 km from Kulen Vakuf. Most full-day rafting routes pass directly in front of it — this is not a detour but the natural highlight of the trip. Guides typically hold position in eddies just above the waterfall lip so participants can take photographs and absorb the view before the river curves around the cascade.

If you are not doing a full rafting day, Štrbački buk is also reachable by foot and vehicle. The access track runs from Kulen Vakuf — approximately 6 km on a dirt road, driveable in a normal car in dry conditions. From the car park, a marked path descends to viewpoints above and beside the waterfall (approximately 10–15 minutes on foot). There is a small kiosk serving drinks and snacks at the trailhead during peak season.

Viewing tip: The waterfall faces northeast — morning light catches the falls directly. Afternoon visits work but lose the sun behind the western canyon wall from around 3 pm in summer.

Una National Park Entry Fees

Una National Park (Nacionalni park Una) charges a day visitor fee. As of 2026, the standard rate is approximately BAM 5 (around €2.50) per adult per day. Children under 12 are usually free or pay a reduced rate of BAM 2–3. Annual passes are available for approximately BAM 30.

Entry fee payment points are located at park gateways near Bihać, Kulen Vakuf, and Martin Brod. If your rafting package includes park entry, confirm this in writing before arrival — some operators bundle it; others expect you to pay separately at the gate.

The park office in Bihać (+387 37 229-979) can provide current fee information and confirm whether your planned route falls within park boundaries.

Season

April to October is the operational season, with June and September the guides’ first choices.

Month	Conditions	Notes
April	High snowmelt flow — fast and cold	Suitable for experienced adults only
May	Strong flow, vivid green water	Excellent conditions, wetsuits essential
June	Peak season begins — great conditions	Best overall balance of flow and temperature
July	Warm water, moderate flow	Busiest month; book ahead for weekends
August	Warmest water, lower flow	High demand from domestic and Croatian visitors
September	Flow rises slightly — less crowded	Often the guides’ preferred month
October	Cool water, autumn colours	Still runnable; wetsuit non-negotiable

The Una does not experience the extreme low water levels of Mediterranean-fed rivers — its alpine and karst sources keep it flowing through the summer, though August can feel calmer than June.

Minimum Age and Fitness Requirements

Most operators accept children from 6 years on the full Una circuit and 4–5 years on the shorter, calmer sections. This is notably more inclusive than the Neretva, which typically sets 12 as the minimum for its main run.

Participants should be comfortable around water. Non-swimmers are accepted by most operators with correct buoyancy aid fitting — confirm this when booking. There is no minimum fitness level required for Class II water, though a basic level of arm strength helps during Class III drops.

What to Bring

Essentials:

• Swimwear or quick-dry shorts (worn under the wetsuit)
• Secure footwear — water shoes or old trainers; no flip flops
• Sunscreen applied before the wetsuit goes on
• A dry change of clothes for after
• Small cash for park entry (if not included), snacks, and post-trip food in Kulen Vakuf or Martin Brod

Optional but useful:

• Waterproof phone case or action camera with mount (operators will not always have a photographer)
• Insect repellent — the banks of the Una in low-flow areas can have mosquitoes in the evening
• A light fleece for mornings in May, June, and September before the canyon warms up

How to Get There

From Sarajevo

Bihać is approximately 340 km northwest of Sarajevo — roughly 4 hours by car via the A1 motorway toward Zenica then the regional roads toward Bihać. Bus services run from Sarajevo’s West Bus Station (Zapadni kolodvor) several times daily; journey time 5–6 hours; tickets from approximately BAM 28–35 (€14–18 as of 2026). Kulen Vakuf (where most rafting departs) is a further 40 km south of Bihać town — most operators offer transfers from Bihać on request.

Given the distance, Una rafting works best as part of a 2–3 day trip to northwestern Bosnia rather than a day trip from Sarajevo.

From Split or the Croatian Coast

Bihać sits close to the Croatian border and is accessible from Split in approximately 3.5–4 hours (via the A1 and then north through the Una valley). From Zadar it is around 2.5–3 hours. Many visitors combine Una National Park with Plitvice Lakes National Park (45 km across the border in Croatia) into a 3–4 day circuit.

From Zagreb

Zagreb is approximately 230 km northwest of Bihać — around 2.5 hours by car. Regular bus services connect Zagreb and Bihać; journey time approximately 3.5 hours; tickets from approximately HRK 100–140 (€13–19 as of 2026). Bihać is one of the most accessible parts of Bosnia from northern Croatia.

Within the National Park

From Bihać, the road to Kulen Vakuf and Martin Brod follows the Una River valley south — a drive of 40–50 km on generally good two-lane roads through the park. Petrol stations are in Bihać; carry a full tank as stations are limited within the park. There is parking at Kulen Vakuf village and at the Štrbački buk trailhead.

Where to Eat Near the Park

Martin Brod has a handful of riverside restaurants serving traditional Bosnian grilled meat. Expect to pay approximately BAM 12–20 (€6–10) for a full meal with a drink as of 2026.

Kulen Vakuf offers several family-run restaurants near the town centre. Lamb roasted over an open fire (janjetina) is the local speciality — order in advance for groups.

Bihać has the widest range of dining options including cafes, pizzerias, and traditional Bosnian mehanas. The old town centre on the Una riverbank is a pleasant place to spend an evening after a day on the water.

Practical Notes

• Currency: Bosnia uses the Bosnian Convertible Mark (BAM), pegged to the euro at approximately €1 = BAM 1.96. Card payment is not reliable at the park entrance or in Kulen Vakuf — bring cash.
• Mobile coverage: Signal is limited in the canyon itself. Download offline maps (Google Maps or Maps.me) before entering the park.
• Park rules: Camping is only permitted at designated sites within the park. Open fires are prohibited outside designated fire areas. Pack out all rubbish — the Una is remarkably clean by Balkan standards and guides take park rules seriously.
• Water quality: The Una is one of the cleanest rivers in Europe. Accidental swallowing of river water is not a concern on this river the way it might be elsewhere.
• Photography from the raft: Waterproof mounts for phones work well on the Una’s moderate water. Bring a mount that attaches to your buoyancy aid strap or helmet rather than relying on a chest mount, which can shift during paddle strokes.
