Trebinje is one of the most rewarding day trips you can make from Montenegro's Bay of Kotor. Less than 90 kilometres from Kotor, this compact Herzegovinian city sits in a sun-drenched limestone valley, crowned by a hilltop church and threaded by the clear Trebišnjica river. Because it lies just across the border in Bosnia and Herzegovina, a little preparation — especially around your rental car — goes a long way.
The Route from the Bay of Kotor
The most practical starting points are Kotor, Herceg Novi, or Tivat. From Kotor, the drive is roughly 85–90 km and takes about 1 hour 30 minutes in light traffic. From Herceg Novi — which sits closer to the border — the distance is around 60 km, making the drive closer to 1 hour 10 minutes. If you are arriving by air, picking up a car at Tivat Airport puts you on the road quickly; Podgorica travellers can also start from Podgorica Airport and drive north through the Bay of Kotor en route.
Via Herceg Novi and the Debeli Brijeg–Ivanica Border Crossing
The standard route heads northwest along the coast toward Herceg Novi, then climbs inland toward the border crossing at Debeli Brijeg (Montenegrin side) / Ivanica (Bosnian side). This is the most direct and most frequently used crossing for travellers heading to Trebinje. The road from the border into Trebinje is roughly 30 km and takes about 30–35 minutes through pleasant Herzegovina countryside.
Road Conditions and Driving Tips
The coastal stretch from Kotor or Tivat toward Herceg Novi is well-maintained and straightforward. The road that climbs toward the border involves some winding sections but is paved and suitable for standard vehicles. An economy or compact car handles the route comfortably; if you plan to explore off the main roads in either country, an SUV offers additional clearance and peace of mind. For a broader picture of what driving in Montenegro involves, the guide on driving in Montenegro is a useful read before any longer excursion.
Cross-Border Rental: What You Need to Know
This is the most important planning step for a Trebinje day trip. Not every rental company permits its vehicles to cross into Bosnia and Herzegovina, and driving across the border without written authorisation is a breach of the rental agreement — potentially leaving you without insurance coverage.
When you book with Montrent, ask specifically for cross-border permission to Bosnia and Herzegovina. You will receive a border crossing letter (also called a Green Card addendum) that lists Bosnia among the approved countries. Carry this document in the car alongside the standard rental paperwork. Border officials on both sides occasionally ask for it.
For a detailed breakdown of cross-border rules, permitted countries, and what documentation to expect, read the dedicated guide on cross-border car rental in Montenegro.
At the Border
- EU, UK, US, and most other Western passports do not require a visa for Bosnia and Herzegovina for short stays — but confirm your nationality's current requirements before travel.
- The crossing at Debeli Brijeg–Ivanica is generally quick outside peak summer weekends. Expect a few minutes for document checks on each side.
- Bosnia uses the Convertible Mark (BAM) as its currency. Trebinje's old town has ATMs and some establishments accept euros, but carrying a small amount of local currency is practical.
- Fuel prices in Bosnia are often slightly different from Montenegro; check the current rate at the pump. The guide on fuel costs and tolls in Montenegro covers the Montenegrin side of the equation.
What to See in Trebinje
Trebinje is compact and walkable once you park. The town rewards a half-day of relaxed exploration, leaving time for lunch before the return drive.
The Old Town (Stari Grad)
Trebinje's fortified old town is a Baroque quarter built during the Ottoman and later Austrian periods. The stone streets are shaded by plane trees, lined with café terraces, and almost entirely free of traffic. It is a genuine working town, not a tourist set-piece, which gives it a quieter character than the more visited sites along the Montenegrin coast.
Hercegovačka Gračanica
Perched on Crkvina Hill above the town, this Serbian Orthodox church is a copy of the famous Gračanica monastery in Kosovo, built in the early 2000s as a memorial to the poet Jovan Dučić. The hilltop provides panoramic views over the Trebišnjica valley and the surrounding limestone ridges — one of the best viewpoints in the region.
The Trebišnjica River and Arslanagić Bridge
The Trebišnjica is one of the longest underground rivers in Europe, surfacing here to flow through the valley. The Ottoman-era Arslanagić Bridge (also known as the Perovića Bridge), relocated stone by stone to its current position in the 1970s, spans the river near the town centre and is worth a short walk.
Wine and Food
The Trebinje area is Herzegovina wine country, and the local žilavka (white) and vranac (red) grapes thrive in the dry, limestone terrain. The old town's restaurants serve regional food — grilled meats, local cheese, and flatbread — at prices noticeably more modest than the Montenegrin coast. A lunch stop here is one of the quiet pleasures of the trip.
Practical Tips for the Day Trip
- Start early. Leaving Kotor or Tivat by 9:00–9:30 gives you a full morning in Trebinje before the return drive in the afternoon.
- Parking in Trebinje is easy and inexpensive; there is surface parking near the old town walls.
- Navigation. Standard GPS apps and Google Maps work reliably for this route. Download an offline map before crossing the border as a backup.
- Mobile data. Check your roaming plan. Bosnia is not in the EU, so EU roaming rules do not apply and charges vary by carrier.
- Return timing. The border can be busier on Sunday afternoons in summer. Build in a small buffer if you are on a schedule.
For parking and old-town driving strategies on the Montenegrin side of the trip, the guides on parking in Montenegro's old towns and Kotor driving and parking are worth bookmarking.
Getting There from Other Bases
If you are staying in Budva or along the Riviera, add roughly 40–45 minutes to the Kotor-based times above. The Bay of Kotor scenic drive makes a natural outbound or return route — combining the Trebinje day trip with a loop around the bay is a full but very satisfying day on the road.

A day trip to Trebinje is one of the most distinctive drives you can make from the Bay of Kotor — different in character from the coast, unhurried, and genuinely worth the short distance. Browse Montrent's available cars and pick up from any of our locations to start the journey on your own terms.
