Rules in force · 8Non-EU visitors get 90 days in any rolling 180-day window…Mine-suspected land still exists in Bosnia and Herzegovin…

Europe ↗Non-EU visitors get 90 days in any rolling 180-day window, counted across all 29 Schengen states together — not per country; the Entry/Exit System now logs each crossing, so an overstay is detected automatically.
Europe ↗On the first Schengen entry since EES began, non-EU travellers give four fingerprints and a face photo at the border instead of a passport stamp; there is nothing to apply for or pay in advance.
Balkans ↗Mine-suspected land still exists in Bosnia and Herzegovina and in pockets of Croatia's former front line: outside towns keep to tarmac and waymarked paths, and treat red triangle signs and taped-off fields as absolute.
Balkans ↗Serbia refuses onward entry to travellers who reached Kosovo from a third country and then try to cross straight into Serbia; route Kosovo–Serbia legs through North Macedonia or Montenegro, or start the loop in Serbia.
Balkans ↗Hire cars need written permission from the rental company and valid insurance for every country on the line; Kosovo sells its own border insurance and some contracts exclude Albania, Kosovo or Bosnia outright.
Bosnia and Herzegovina ↗Bosnia and Herzegovina is outside the EU and Schengen area and sets its own entry rules; check the official requirements for your passport.
Bosnia and Herzegovina ↗Do not leave paved roads or marked trails in rural areas, and never enter damaged or abandoned buildings: landmine risk remains in places.
Bosnia and Herzegovina ↗Coastal Croatia and Montenegro connect by bus; allow extra time for border queues in summer.

Bosanska Krajina is the north-west corner of Bosnia and Herzegovina, a rough triangle against the Croatian border, split between the Federation and Republika Srpska. It is river country: the Una, Sana, Vrbas and Pliva all run through it, and the towns sit 45–150 minutes apart on slow roads. Sleep in Banja Luka for city food and Vrbas access, in Bihać for Una National Park; day-trip Jajce, Krupa na Vrbasu and the smaller towns rather than moving hotels every night.

Plan the nights

How to split the nights, day-trips and what to do with your bags

Open Plan the nightsClose Plan the nights3 partsNights · Day-trips · Bags

Night sequences

3 nights: Banja Luka 2 + Bihać 1 (Una day)
5 nights: Banja Luka 2 + Jajce day + Bihać 2 (Una National Park)
7 nights: Banja Luka 3 + Prijedor or Kozara 1 + Bihać 3, with Jajce as a day-trip

Banja Luka to Bihać is about 2 h 30 by car on a two-lane road; buses take longer, so do not plan both ends of the day in different towns.
Una National Park's Štrbački buk and Martin Brod entrances are far apart; check which one you are heading for before you set off.
Some rural roads and mountain passes are unlit and narrow; avoid driving them after dark.

Day-trips door to door

To	From	Door-to-door p50	Last return	Note
Jajce	Banja Luka	105 min	unknown	Bus and car both about 1 h 45; the waterfall and old town take half a day.
Krupa na Vrbasu	Banja Luka	35 min	unknown	Short taxi or bus ride; go for the morning and swim before the afternoon heat.
Una National Park	Bihać	40 min	unknown	Entrance is at Martin Brod and Štrbački buk; a car makes the loop far easier than buses.
Bosanska Krupa	Bihać	45 min	unknown	River swimming and rafting put-ins; pair it with the Una park on the same day.
Glamoč	Bihać	90 min	unknown	High plateau; only worth it with your own car and a full day.

Bags between cities

No luggage-forwarding service in the region; travel with your bag or leave it at the hotel between bases.

Regional passes

Verdict first

Una National Park entrance ticket

buy

Pays for the waterfall areas and trails; buy at the entrance you reach, prices are modest and set locally.

Rental car

buy

The region rewards a car: buses between the smaller towns are infrequent and slow.

Rafting or kayaking day trip on the Una

check

Operators run from Bihać and Bosanska Krupa; confirm the meeting point and whether transport is included.

Regional food

Where and when it works

Dish	Where	Timing / trap
Ćevapi and somun	Banja Luka and every larger town	Order by the portion (5 or 10); cheapest and fastest sit-down meal.
Grilled river trout	Una and Sana valley restaurants	Often the freshest thing on the menu; ask if it is local catch.
Lamb on the spit (janjetina)	Roadside restaurants near Jajce and Mrkonjić Grad	Usually sold by weight; agree the price before ordering.
Pita (meat, cheese or spinach pie)	Bakeries and market stalls	Buy by the slice; a cheap breakfast or picnic item.
Local rakija and Bosnian coffee	Cafés in Banja Luka and Bihać	Coffee is served in a small pot with a sugar cube; rakija is strong, sip it.
