The Una Valley Tourist Train — Bihać to Bosanska Otoka

In the far north-west corner of Bosnia and Herzegovina, where the country narrows to a point between two arms of Croatia, there is a river that people travel a long way to look at. The Una runs clear and cold off the Dinaric karst, and it is green — not the vague green of most rivers, but a bright mineral jade that turns white every few hundred metres as it drops over limestone shelves. Bosnians call it a beauty and mean it literally.

A railway was laid along that valley a century ago, for the ordinary reason that the valley was the only flat ground. For most of the last thirty years no scheduled passenger train has used the stretch north of Bihać. In June 2026 that changed: the state operator put a short train back on the line for the summer weekends, charged two convertible marks for a ticket — about a euro — and discovered it had a hit on its hands. Five thousand people rode it in the first month.

This is not a heritage railway. There is no polished steam locomotive, no restored dining car, no guide with a microphone. It is a plain electric train of the sort that works branch lines all over the Balkans, running an hour up a river valley and an hour back, and the whole appeal is that the valley is lovely and the fare is nothing. You buy a paper ticket at the window, you sit by a big window, and the Una is there beside you for most of the way.

The run goes north from Bihać — a town first written down in 1260, with a Gothic church that has been a mosque since 1592 — through the wooded narrows to Bosanska Krupa, where the river comes down through the middle of town in a broad staircase of falls beneath a ruined fortress, and on to Bosanska Otoka. Most passengers get off at Krupa, spend a couple of hours by the water, and come back on the afternoon train.

It runs on Saturdays and Sundays, in June, July and August, and at the time of writing the operator has promised nothing beyond that. If you are in this corner of the country on a summer weekend, take it while it is there.

The train leaves Bihać at nine in the morning. The station is a low inter-war building with its name painted up in both alphabets, a few tracks, and none of the ceremony of a tourist attraction — which is part of the charm, because for an hour either side of departure it is the busiest place in town.

Out of Bihać

The line runs north, downstream. Bihać sits in a basin where the Una briefly slows and spreads, and the first few kilometres are gentle: gardens, allotments, the backs of houses, the river appearing on the right between trees. At Brvice, on the edge of town, the water comes over a long low weir into a pool the colour of bottle glass — one of the places locals swim on a hot afternoon.

Then the hills close in. The valley between Bihać and Bosanska Krupa is wooded on both sides and narrow enough that the railway, the road and the river have to share it, and for long stretches you can see all three at once. There is nothing dramatic here — no great viaducts, no tunnels through cliffs — but it is continuously pretty in a way that a fast road never is, and the train is slow enough to look at it.

Bosanska Krupa

About forty minutes out, the valley opens and the train comes into Bosanska Krupa. This is the stop that matters. The Una arrives in the middle of the town across a wide bed of limestone terraces and comes down in a staircase of white cascades, with islands and footbridges and a park on the bank; above it, on a crag, stand the walls of the old fortress. Nearly everyone gets off.

If you are doing the classic day out, this is where you spend it: the morning train gives you until 11:45, which is time enough to walk the riverside, climb to the fortress for the view back down the valley, and drink a coffee somewhere with the sound of falling water in it.

On to Bosanska Otoka

The train carries on for another quarter of an hour to Bosanska Otoka, crossing the Una line's old truss bridge at Podvran on the way. Otoka is smaller and quieter — a village on a slow green reach of the river, and the northern end of the run. There is less to do here than at Krupa, which is precisely why some people prefer it.

The train itself

The service is worked electrically, under wires strung when the line was upgraded in 1987. The railway prepared several vehicles for it — an electric locomotive with a coach, and a two-car electric unit, 411-114, of a Hungarian design that has been running in this part of the world for decades. Which one turns up depends on the day. Either way the interior is plain: fabric seats in facing pairs, wide windows that open, and a good deal of legroom. Nobody serves anything. Bring water in August.

Before the season could start, crews spent late May clearing the track corridor and repairing the overhead line, which storms had damaged; the contact wire was back in order on 3 June, two days before the first train ran.

The Una tourist train runs Saturdays and Sundays only, during June, July and August. There is no weekday service and nothing at all outside the summer.

Departures — as of August 2026

Two round trips a day, then. The morning pair is the one to take if you want time at the far end: leave Bihać at 09:00 and you have until 11:45 before the return. The afternoon pair — out at 16:00, back at 18:20 — is the shorter, cooler option, and pleasant in high summer when the middle of the day is too hot to enjoy the riverbank anyway.

How long it takes

The operator does not publish a full station-by-station timetable for this service, but it did publish intermediate times for one late-night special. Those give the shape of the run: Bosanska Krupa to Bihać took 39 minutes, and Bosanska Otoka to Bosanska Krupa 15 minutes. Reckon on roughly 40 minutes from Bihać to Bosanska Krupa and a little under an hour end to end.

Changes happen

This is a young service on a line that has only just got its passengers back, and the timetable moves for local events. On Saturday 1 August 2026, for the sixth Bosanska Krupa Una regatta, the evening return was retimed at the canton's request to leave Bosanska Otoka at 23:15, reaching Bihać at 00:40 the following morning — while the 09:00 and 16:00 departures from Bihać and the 11:45 from Otoka ran as normal. Extra trains have also been laid on for the regatta itself and for the Avantura Film Festival.

Two practical consequences. First, check the operator's notices in the week you travel rather than trusting a timetable printed earlier in the season. Second, be careful with press reports: the service was launched in June as a Bihać–Bosanska Krupa run with a 10:15 and 18:10 return, and a good deal of coverage still says so. It has since been extended to Bosanska Otoka and the return times have changed.

Where to check

Notices and schedules are published by the operator, Željeznice Federacije Bosne i Hercegovine, at zfbh.ba (opens in a new tab). The tourist-train announcements appear on the front page as news items rather than in the main timetable, so scroll rather than search.

Timetable confirmed against the operator's own published notices, August 2026.

A single ticket costs 2 KM — two convertible marks, a little over one euro — in either direction, whatever distance you travel. The operator describes the fare as symbolic, and it is: the point of the price is to get people onto the train, and it has worked. Buy at the station window before you board; there is no online sale and no reservation, and cash in convertible marks is the safe assumption.

The train is short, typically a two-car unit, and on a fine July weekend it fills, so turn up at Bihać fifteen or twenty minutes early. For two marks you get the ride and nothing else — no catering, no commentary, no first class — so bring water and something to eat if you are making a day of it. For a bicycle on a busy summer train, ask at the window rather than assuming.

Short version: do not buy a rail pass for this train. A single costs 2 KM — about one euro — and no pass in Europe can improve on that.

Why a pass makes no sense here

The Una tourist train is priced deliberately low, and the whole round trip from Bihać to Bosanska Otoka and back costs about the same as a coffee. Even if a pass covered it outright, the saving would be two marks. A Global Pass costs many times that for a single day of validity.

If you are carrying one anyway

There is no One Country Pass for Bosnia and Herzegovina — Interrail states it "is not available" — so the only pass that covers the country at all is the Interrail Global Pass, or the Eurail Global Pass from outside Europe. If you already hold one for a wider Balkans trip, it is worth knowing two things.

First, Bosnian trains carry no seat reservations: in Interrail's words, "you can board all trains and find your preferred seat." Nothing to book here in any case.

Second, ⚠️ on ŽRS trains only a paper Interrail pass is accepted, not a mobile one. That does not bite on this journey — the Una tourist train is run by ŽFBH — but it will if you continue east or north into the Republika Srpska network.

What a pass will not do

⚠️ This is a seasonal tourist service, run weekends only in June, July and August, and it is not part of the standard ŽFBH timetable. Do not assume a pass entitles you to a seat on it. Buy the two-mark ticket at the window like everyone else — it is simpler, it is certain, and the money goes to the canton that pays for the train.

The train links two towns that are worth your time and one village that is worth your quiet, and everything of interest is within a short walk of a station — which is unusual, and part of why the service works as a day out.

Bihać is the base. It has been a town since at least 26 February 1260, when a charter of the Hungarian king Béla IV described a settlement on an island in the Una, and its two best buildings both stand a few minutes from the water. The Fethija was built in 1266 as the Church of St Anthony of Padua and is the oldest Gothic building in the country; it became a mosque after the Ottoman conquest of 1592, and the medieval shell came through the change intact. Down the street, the Captain's Tower — a square keep of uncertain age, on the maps by 1697 — spent the Austro-Hungarian period and beyond as a prison and now holds the Una-Sana Canton museum.

Bosanska Krupa, forty minutes up the line, is where the river performs. The Una arrives across a wide bed of limestone and comes down through the middle of the town in a staircase of cascades, with a park, footbridges and islands, and the ruined fortress on its crag above. It is a small place and you will have seen it properly in two hours.

Bosanska Otoka, at the end of the run, is a village on a slow green reach of the Una with a bridge, a few cafés and not much else. That is the appeal.

One important thing lies in the other direction. Štrbački buk, the Una's great waterfall, is upstream of Bihać inside the national park, and the railway does not go there — it needs a separate trip by road. It is the finest single sight in the region and worth a day of its own.

Because the train runs out and back twice in a day, this is a journey you sleep at one end of rather than along. Bihać is the obvious base: it is the largest town in the region, the train starts and finishes there, and it is the natural jumping-off point for Una National Park as well.

The town has the usual range of a mid-sized Bosnian centre — a handful of hotels, a larger number of small guest houses and rented apartments, and a scattering of riverside places a little way out towards the national park. Prices in this corner of the country are low by European standards, but July and August are the season for both the river and the rafting trade, and weekends fill.

Bosanska Krupa has less choice and makes more sense as a day trip than a base, though staying there does put the cascades outside your window in the evening after the last train has gone. If you are travelling on to Croatia, note that Bihać is close to the border and the crossings north and west of it are the usual routes towards Zagreb and the coast.

A practical note about the train rather than the beds: the service runs only at weekends, so build the ride into a Saturday or Sunday and use the weekdays for the national park, the rafting, or the road down the valley. There is nothing to be gained from timing an arrival for a Tuesday.

We do not yet list individual hotels for this journey. When we do, they will be places we have checked rather than places that have paid to appear.
