Driving Bosnia's backroads — notes from the mountain roads
Bosnia does not have a complete motorway network. This is, depending on your disposition, either a problem or the best news you will hear all week.
The main routes — Sarajevo to Mostar, Sarajevo to Banja Luka via the A1 motorway extension — are modern, fast, and efficient. But the country between them is served by mountain roads that take the long way around because there is no shorter way. These roads pass through places where tour buses don’t go and where the landscape is entirely unmediated by tourist infrastructure.
Driving them is one of the better ways to see Bosnia.
The realities first
Some honest advance warnings before the enthusiasm:
The roads are slower than they look. A 120-kilometre route in Bosnia might take three hours. Mountain roads with steep gradients and hairpin bends do not yield the kilometre counts that flat motorways do. Build in extra time for every journey.
Some roads close in winter. Mountain passes above 1,200 metres can be impassable from December to March. The route through Sutjeska National Park, for instance, is high altitude; check conditions before driving in winter months. The driving in Bosnia guide has current advice on seasonal road closures.
Some roads are unmarked. In rural areas, particularly in the hills east and south of Sarajevo, signage is inconsistent. Offline maps (Maps.me or downloaded Google Maps) are more reliable than expecting data coverage on mountain ridges.
Rental car cross-border rules. If entering from Croatia or Montenegro, ensure your rental car has the green card international insurance document covering Bosnia-Herzegovina (not all Croatian rental companies include this automatically). See the renting a car guide for specifics.
The Neretva canyon road
The road from Sarajevo south to Mostar runs alongside the Neretva River through a narrowing canyon for most of its length. It is one of the more dramatic approaches to any city in the Balkans — limestone walls rising above the green river, tunnels cut through promontories, the occasional railway bridge across the gorge below.
The motorway (M-17) covers much of this route now, which speeds the journey but removes some of the canyon experience. The old road (M-17 designation retained in places) runs closer to the river and is worth taking if you have time — especially the section between Jablanica and Konjic.
Pull over for Konjic on the way. The old stone bridge over the Neretva, the river-view restaurants, and Tito’s Bunker nearby make a worthwhile two-hour stop.
The road to Jajce
The route from Sarajevo northwest to Jajce via Kiseljak and Travnik is a good example of how Bosnian roads work: mostly paved, reasonable surfaces, speed limited through towns, mountain stretches that are winding but well-maintained. Allow 2.5 to 3 hours for what the map suggests is 160 kilometres.
The Lašva valley section through Travnik is the cultural heart of central Bosnia: Ottoman fortress, coloured Mosque, the old bazaar, the birthplace of Ivo Andrić (the Nobel laureate writer, born here in 1892). Stop for coffee and a walk — Travnik deserves an hour at least.
Jajce, another 40 minutes north, sits at the confluence of the Pliva and Vrbas rivers. The waterfall in the centre of town, the medieval fortress above, and the Pliva Lakes and watermills nearby make for a genuinely rewarding stop.
The mountain road to Lukomir
The road to Lukomir from Sarajevo is a different category of driving experience: paved for most of the ascent to Bjelašnica, then a rough track for the final section to the village. A standard car with reasonable clearance can manage it in dry conditions; after rain or in early spring with snow still on the plateau, a 4x4 is advisable.
The plateau views are worth whatever the road demands. From the ridge above Lukomir, you look down into the Rakitnica canyon on one side and across to the Olympic ski runs on the other. The village itself is a handful of stone houses and wooden barns that look much as they have for a century.
Allow half a day for the drive and village from Sarajevo.
The Una valley road
The road through the Una valley in northwest Bosnia — roughly from Bihać south along the Una to Kulen Vakuf — is one of the most beautiful drives in the country. The Una runs in a gorge of exceptional clarity, the water that luminous blue-green that appears in all the photographs, with the canyon walls closing in on both sides.
This road does not connect to anywhere particularly efficiently. That is entirely the point. From Bihać, drive south to Kulen Vakuf, continue to the Štrbački Buk waterfall, and loop back via the ridge road above the valley. A full morning is appropriate.
Eastern Bosnia: towards Višegrad and Sutjeska
The road from Sarajevo east to Višegrad and then south to Sutjeska National Park is the longest and most remote of the standard tourist routes. The road is good as far as Foča; the section into the national park narrows and climbs through forest.
The Sutjeska guide has practical road information for the park approach. Plan a full day minimum; the distances are deceptive and the mountain terrain means much of the driving is in first or second gear.
What to bring
- Full tank of petrol when leaving cities — mountain stations exist but are not guaranteed
- Cash for small restaurants and stops in villages
- Offline maps downloaded before you leave
- A willingness to add 30 minutes to every journey estimate
The Bosnia travel planning guide has broader practical information including transport options for non-drivers.
