Dubrovnik in 4 days: Old Town plus Mostar and Kotor day trips

Dubrovnik as a base for three countries in four days

Dubrovnik’s geographical position — wedged into the southernmost tip of Croatia, with Montenegro 30 km to the south and Bosnia-Herzegovina accessible within 2.5 hours — makes it the natural base for one of Europe’s best multi-country itineraries. Four days gives you two days to explore the Old Town properly, then a day trip to Mostar in Bosnia and a day trip to Kotor in Montenegro. Three countries, three UNESCO World Heritage Sites, no car required.

The moderate rating reflects the border crossings: not physically demanding, but logistically realistic. Budget a minimum of 30–60 minutes for the Bosnia border and 20–40 minutes for Montenegro. Both borders can queue in July–August. Organised tours handle all of this for you.

Day 1: Dubrovnik — the city walls and Old Town

Morning: walls at opening time

Start at Pile Gate when the city walls open at 8 am. The 2 km circuit with stops takes 90 minutes. This is the essential Dubrovnik orientation — the continuous view from the ramparts makes the city’s layout immediately comprehensible.

Guided city walls tour with local historical commentary and included entry

Book tickets online in advance if visiting June through September.

Afternoon: Old Town and cable car

Spend the rest of the day at street level: the Franciscan Monastery’s medieval pharmacy, the Rector’s Palace, the Dominican Monastery, and the lanes above the Stradun.

Srđ cable car round trip — 405 metres above Dubrovnik with panoramic views

Take the cable car to Srđ in the mid-afternoon. The fort’s museum covers the 1991–1992 siege with photographs and artefacts that contextualise the city’s recent history alongside its medieval magnificence.

Evening: dinner in the Old Town

The lanes south of the Stradun have the best concentration of konobas at reasonable prices. Order anything with Plavac Mali wine and local fish or lamb.

Day 2: Dubrovnik — Lokrum and sea kayaking

Morning: ferry to Lokrum

Take the first Lokrum ferry from the Old Town harbour at approximately 9 am (May–October, €21 return). Spend the morning on the island: the Dead Sea lake, the monastery ruins, Fort Royal summit, and the peacocks. Return by noon.

Afternoon: sea kayaking

Half-day sea kayaking tour along the base of the city walls and around the Old Town harbour

The afternoon kayaking session (typically 3 pm, 3 hours) sees the walls from water level — a radically different perspective from the ramparts. No experience required.

Evening: sunset cruise

Karaka galleon sunset cruise along the Dubrovnik walls with drinks

End the Dubrovnik chapter with a sunset sail. Book this as far in advance as possible — it sells out fast in peak season.

Day 3: Mostar day trip (Bosnia and Herzegovina)

Early departure

Leave Dubrovnik by 7 am to maximise time in Mostar. The journey is approximately 2.5 hours by organised tour bus or private transfer, including the Bosnia border crossing at Ivanica. Budget 30–60 minutes for the border in summer; July and August can stretch to 90 minutes.

Bosnia uses the convertible mark (BAM); 1 EUR ≈ 1.96 BAM. Most tourist-facing places in Mostar accept euros at a slight disadvantage; it is worth carrying some BAM for smaller purchases.

Mostar highlights day trip from Dubrovnik including Stari Most bridge and the old bazaar

Mostar is centred on Stari Most — the 16th-century Ottoman bridge (destroyed in 1993 and rebuilt in 2004) that arches over the Neretva river between the Bosniak and Croat quarters of the city. The surrounding Bašćaršija bazaar, the minarets, and the Ottoman-era hans make this one of the most distinctive cities in the Balkans.

What to see in Mostar

Allow 4–5 hours in the city: the bridge itself and the views from both banks, the climb to the clifftop for a diver’s view of the bridge (local professional divers jump daily in summer), the mosque and its minaret, and lunch at one of the riverside restaurants serving ćevapi, burek, or grilled lamb.

The Kravica waterfall, 40 km from Mostar, is sometimes combined with this day trip — a horseshoe waterfall descending into a turquoise swimming pool, popular in summer.

Return to Dubrovnik

Allow 3 hours for the return journey including border crossing. Aim to be back in Dubrovnik by 8 pm. Dinner is perfectly possible in the Old Town on return.

Day 4: Kotor day trip (Montenegro)

Morning departure

Kotor is approximately 90 km from Dubrovnik — around 1 hour 45 minutes by organised tour, including the Montenegro border crossing at Debeli Brijeg. The border is generally faster than the Bosnia crossing: budget 20–40 minutes. Montenegro uses the euro.

Kotor city tour with the old town, St Tryphon Cathedral, and the Venetian fortifications

Kotor is a Venetian-era walled city in a fjord-like bay: the Boka Kotorska (Bay of Kotor). The setting is extraordinary — dramatic limestone mountains drop almost vertically into the bay, with the medieval walls climbing impossibly steep above the town.

What to see in Kotor

The walled old town is compact and walkable in 2–3 hours. The Cathedral of St Tryphon (dating to 1166), the Venetian clock tower, the maritime museum, and the warren of medieval squares are the main sights.

The fortification walls above the old town climb 1,355 steps to St John’s Fortress — a steep but rewarding 45-minute climb with increasingly extraordinary views. Allow 90 minutes for the ascent and descent.

Boat trip to Our Lady of the Rocks island church near Perast in the Bay of Kotor

If the day trip schedule allows, the village of Perast — 15 km along the bay from Kotor — is one of the most beautiful baroque villages in the Adriatic. A short boat trip reaches the island church of Our Lady of the Rocks, an artificial island built by local sailors over centuries.

Return to Dubrovnik

Return to Dubrovnik by late afternoon. Allow 2 hours for the return journey with border crossing.

Practical notes

Organised tours vs self-drive: Without a car, organised tours are the clearest option for both Mostar and Kotor. They handle border logistics, include guides, and run on fixed schedules. The day trips guide covers operators and current prices.

Border crossings: Bosnia and Montenegro are not EU Schengen countries. EU passport holders cross easily; non-EU nationals (UK, US, etc.) typically get a stamp and are waved through. Allow buffer time. Both countries are outside the EU VAT zone — VAT refunds do not apply for purchases.

Day order: Consider reversing days 3 and 4 based on weather. Mostar can be extremely hot in mid-summer (inland heat, minimal shade). Kotor is cooler in the bay. The Kravica waterfalls swim is most tempting on the hottest days.

Where to sleep: Staying in the Dubrovnik Old Town or Lapad Bay for all 4 nights keeps logistics simple. No overnight pack required.

Currency: Croatia EUR. Montenegro EUR. Bosnia BAM (keep €20–30 in BAM for Mostar).

Frequently asked questions about this itinerary

Is it possible to do both Mostar and Kotor as day trips from Dubrovnik?

Yes — this is one of the most popular multi-day Dubrovnik itineraries. The distances work: Mostar is 2.5 hours, Kotor is 1.75 hours. The border crossings add time but are manageable. The best day trips from Dubrovnik guide covers both in detail.

Do I need a visa to visit Montenegro and Bosnia from Croatia?

Most Western passport holders (EU, UK, US, Canada, Australia) can enter both Montenegro and Bosnia without a visa for stays under 90 days. Check current requirements for your specific nationality before travel.

Should I go to Mostar or Kotor first?

Mostar is a longer journey with a more complex border crossing — go earlier in the trip when you’re fresher. Kotor is closer and faster. Both are included in the 4-day Montenegro and Bosnia itinerary if you want to explore further into both countries.

Are the day trips suitable without a car?

Yes. Organised group tours run daily from Dubrovnik to both Mostar and Kotor from May through October. Private transfers are also available. Public bus services exist but involve multiple changes and long waits at borders.

How much time do you actually get in Mostar on a day trip?

A well-run Mostar day trip from Dubrovnik gives you 4–5 hours in the city, accounting for 2.5-hour journeys each way and border crossing time. This is enough for the bridge, the bazaar, and a sit-down lunch. Adding Kravica reduces city time to 3 hours.
