Mostar Day Trip by Rental Car: Route, Border, Full-Day Plan
TL;DR
- Fastest route: inland via the Metković border — 140 km, about 2h15 each way.
- Bosnia is outside the EU and Schengen. You need your passport plus a green card for the car; our €45 cross-border pack covers the paperwork.
- Currency is the convertible mark (BAM), fixed at roughly 1.95 to the euro. Euros are widely accepted.
- Leave at 07:30, return by 19:00 — enough time for Stari Most and the Kravica waterfalls.
Mostar is the day trip that surprises people the most. In one long day you swap the Adriatic for Ottoman minarets, watch divers plunge off a 16th-century bridge, swim under a waterfall, and still make it back to Dubrovnik for a late dinner. It does take a border crossing and a little paperwork, though — so here is the exact plan we give our own guests, updated for the 2026 season.
Which route should you take to Mostar?
Take the inland route through the Metković border crossing. It is 140 km and about 2 hours 15 minutes each way: follow the D8 coastal road north past Ston, continue through the Neretva delta to Metković, cross into Bosnia and Herzegovina at Doljani, then join the M-17 straight up the Neretva valley into Mostar. The road is good the whole way, and fuel is available on both sides.
The alternative is the old coastal route through Neum. You cross into Bosnia on the coast at Neum, then climb inland through Stolac on narrower regional roads. The distance is similar, but count on an extra 20–30 minutes of driving. The upside: the Neum crossing is usually quieter in peak season, and the karst scenery around Stolac is genuinely beautiful. Many of our guests drive up via Metković and come home via Neum to see both.
One quirk of local law worth knowing before you set off: in Bosnia and Herzegovina, dipped headlights are mandatory at all times, day and night — not just in winter as in Croatia. Turn them on at the border and leave them on.
What documents do you need to cross the border?
You need a valid passport for every person in the car, plus a green card (international motor insurance certificate) and written cross-border authorization for the vehicle. Croatia is in the EU and the Schengen Area; Bosnia and Herzegovina is in neither, so this is a full external border with passport checks in both directions.
With us the car side of it is simple: add the €45 cross-border pack when you book your car, and we hand you the green card and authorization letter at pickup. Without those two documents the Bosnian border police can — and do — turn rental cars around. Some visitors also need a visa for Bosnia and Herzegovina depending on nationality; EU, UK, and US passport holders do not for short tourist visits, but check your own country’s rules before you go.
What currency is used in Mostar?
The official currency is the Bosnia and Herzegovina convertible mark (BAM, locally “KM”), which is pegged to the euro at a fixed rate of about 1.95 BAM per €1. In practice, euros are accepted almost everywhere tourists go in Mostar — restaurants, parking attendants, souvenir stalls — usually converted at that same 1.95 rate, with change given in marks.
Our advice: pay by card where you can, keep €20–30 in small euro notes for parking and snacks, and don’t change large sums into BAM you won’t spend. Marks are hard to exchange back once you’re home.
What is the best one-day itinerary?
This is the schedule we recommend to guests who want Stari Most, a proper lunch, and the Kravica waterfalls without rushing. It assumes a 07:30 start from the city.
| Time | Stop | Notes |
|---|---|---|
| 07:30 | Depart Dubrovnik | Full tank, documents ready |
| 09:00 | Metković / Doljani border | Before the midday queues build |
| 09:50 | Arrive Mostar, park | Paid lot near the old town |
| 10:00–13:00 | Stari Most and old bazaar | Bridge, divers, Koski Mehmed Pasha minaret |
| 13:00–14:15 | Lunch in the old town | Try ćevapi by the river |
| 14:15–15:00 | Drive to Kravica | About 40 minutes via Ljubuški |
| 15:00–16:30 | Kravica waterfalls | Swim in summer; bring towels |
| 16:45–17:15 | Back roads to the border | Kravica sits close to the route home |
| 19:00 | Arrive Dubrovnik | In time for dinner |
What should you see at Stari Most?
Stari Most, the “Old Bridge,” is the reason most people come: a single stone arch built for the Ottomans in 1566, destroyed by shelling in 1993, and rebuilt stone by stone in 2004. The bridge and the old town around it are UNESCO-listed, and the local diving club keeps a much older tradition alive — divers collect tips from the crowd, then leap roughly 20 meters into the cold, green Neretva below. If you stand on the bridge and someone in a wetsuit is pacing the parapet, wait a few minutes; the jump is worth seeing.
Give yourself time on both banks. The cobbled Kujundžiluk bazaar, the minaret of the Koski Mehmed Pasha Mosque (the classic photo angle of the bridge), and the Crooked Bridge — a miniature of Stari Most — are all within a ten-minute walk.
Is the Kravica waterfalls detour worth it?
Yes — especially from June to September. Kravica is a 25-meter arc of waterfalls on the Trebižat river, about 40 minutes’ drive from Mostar near Ljubuški, and it conveniently sits close to your route back toward the Metković border. There is a modest entrance fee (payable in BAM or euros), a walkway down to the pool, and swimming is allowed in summer. Pack towels and water shoes; the lagoon is busiest between 12:00 and 15:00, which is exactly why our itinerary puts you there after 15:00.
Where do you park in Mostar?
Use the paid lots ringing the old town — the historic center itself is pedestrian-only. There are attended lots on both banks of the Neretva within a 5–10 minute walk of Stari Most; expect a few marks per hour or a flat daily rate, and most attendants happily take euro coins. As anywhere touristy, take valuables with you and leave nothing visible in the car. Street signage is thinner than in Croatia, so set your parking lot as the navigation target, not “Mostar.”
How do you avoid border queues?
Cross early and come back either before 17:30 or after 20:00. In July and August the midday wait at Metković/Doljani can stretch to 30–60 minutes each way; at 08:30–09:00 you’ll usually roll through in ten. Have all passports and the green card in the driver’s hand before you reach the booth — fumbling through bags is what actually slows the line. If the queue at Doljani looks bad on the return, the smaller crossings on the Neum route are a solid plan B.
One more warning: Bosnia and Herzegovina is not part of the EU “roam like at home” zone, so your EU or UK plan may bill roaming data at painful rates. Download offline maps for Herzegovina before you leave Croatia, then switch data roaming off at the border.
