Day trips from Herceg Novi: the 6 best excursions
What is the best day trip from Herceg Novi?
The Bay of Kotor cruise from Herceg Novi covers the full sweep of the bay — Perast, Our Lady of the Rocks, and Kotor — in one scenic day. For a quick cross-border option, Trsteno Arboretum in Croatia is only 30 minutes away and makes an easy half-day.
Herceg Novi: the gateway town with good access in both directions
Herceg Novi sits at the mouth of the Bay of Kotor — one foot in the Adriatic, one foot facing the inner bay. This position gives it day-trip options in both directions: north into Croatia (Dubrovnik is 50 km away), south and east into the Bay of Kotor and Montenegro’s interior.
The town itself rewards a morning’s walk — the Ottoman Kanli Kula fortress, the Venetian Sea Fortress, stepped streets of Mediterranean gardens — but its real strength is as a base. Dubrovnik is closer from Herceg Novi than from anywhere else in Montenegro.
All drive times are from central Herceg Novi.
1. Bay of Kotor full-day boat cruise — from the bay mouth inward
Departs: Herceg Novi waterfront
Duration: full day (7–8 hours)
Best for: those who want to see the entire bay in one sweep
The boat cruise from Herceg Novi works the opposite direction from Kotor-based tours: starting at the bay mouth, working inward toward Perast and Kotor. This gives the cruise a natural dramatic structure — the bay narrows as you go deeper, the mountains grow taller, and Perast appears at the inner bay’s edge like a Baroque surprise.
A full-day cruise typically includes: Mamula Island stop (30 minutes), Perast waterfront (1 hour), boat transfer to Our Lady of the Rocks island church, Kotor Old Town stop (1.5–2 hours), and the return sweep along the opposite shore.
Herceg Novi’s cruises also have better access to the Blue Cave (Plava Špilja) near Mamula, a sea cave only accessible by boat.
Kotor: Private Tour to Lovćen, Cetinje & Budva2. Mamula Island — the fortress island half-day
Duration: 3–4 hours (boat excursion)
Best for: history, swimming, easy half-day on the water
Herceg Novi is the closest departure point for Mamula Island — the circular 19th-century Austrian fortress island at the bay mouth, surrounded by turquoise water and accessible only by boat. Excursions from Herceg Novi typically run 3–4 hours, including time to explore the fortress exterior, swim in the clear water around the island, and visit the nearby sea cave.
The island has a layered history: Austrian fortification, Italian World War II internment camp, and now an ongoing conversion into a boutique hotel (the outer areas remain accessible). The combination of dramatic architecture and exceptional water colour makes it the most distinctive short excursion from Herceg Novi.
Look for day boats departing from the Herceg Novi harbour (Škvjer) in season. No advance booking required for group tours; private boat hire is also available.
3. Trsteno Arboretum — Croatia half-day
Drive time: 30 minutes (cross-border, Croatia)
Border time: minimal at Debeli Brijeg crossing (mostly a document check)
Duration: half-day (3–4 hours)
Best for: garden lovers, those curious about the Game of Thrones filming location
The Trsteno Arboretum — a 15th-century Renaissance garden north of Dubrovnik, featuring ancient plane trees and formal gardens overlooking the sea — is only 30 minutes from Herceg Novi across the Croatian border. The border crossing at Debeli Brijeg (the main crossing between Montenegro and Dubrovnik) is generally quicker here than at the main coastal road checkpoint.
Trsteno gained fame as one of the filming locations for Game of Thrones (the King’s Landing gardens), but its intrinsic interest predates the series: the stone aqueduct, the 500-year-old plane trees with trunks too wide to embrace, and the terraced garden dropping to the Adriatic make it a genuine horticultural monument.
Non-EU visitors need to bring their passport. EU citizens need only their national ID card.
4. Dubrovnik — the closest Montenegro base for Croatia’s pearl
Drive time: 50 minutes (without border queues)
Border time: 30 minutes minimum shoulder season; up to 2 hours July–August
Duration: full day (9–11 hours total)
Best for: anyone who hasn’t yet seen Dubrovnik
Herceg Novi is the best base in Montenegro for a Dubrovnik day trip — closer than Kotor (50 km vs 90 km) and with less road to cover. The border crossing at Debeli Brijeg is the main Herceg Novi route into Croatia.
Drive early (leave by 8:00), spend 4–5 hours in Dubrovnik’s Old Town, and return in the evening. The worst queues are at the border in the middle of the day; going first thing and returning after 18:00 helps avoid the peak.
Alternatively, take a boat from the Herceg Novi harbour directly to Dubrovnik — some seasonal connections run in summer, shorter than the road journey and free of border formalities.
See the Dubrovnik to Montenegro day trip guide for full border and logistics details.
5. Lovćen National Park + Cetinje — the mountain day
Drive time: 1h30 to Cetinje
Duration: full day (8–9 hours)
Best for: those who want Montenegro’s mountain interior and royal capital
From Herceg Novi, the drive to Cetinje via the Bay of Kotor road (through Kotor and up the 25 serpentine hairpins) takes 1h30. Alternatively, take the tunnel route through Kotor and continue toward Cetinje — a more direct line but missing the coastal scenery.
Cetinje offers the former royal palace (Biljarda), the National Museum, and the quiet dignity of a capital that once mattered enormously. From Cetinje, a 20-minute drive climbs to Lovćen National Park and the Njegoš Mausoleum at 1,660 metres — the most famous summit view in Montenegro, looking back across the bay you left that morning.
Return via the spectacular serpentine road to Kotor and the bay road back to Herceg Novi for a loop that covers both the coastal and the mountain character of western Montenegro.

6. Kotor Old Town + Perast — the short inward trip
Drive time: 50 minutes to Kotor (via the bay road)
Duration: half-day to full day
Best for: those who want culture and Baroque villages close to home
Kotor is 50 minutes from Herceg Novi via the bay road, or 35 minutes via the tunnel shortcut (faster but less scenic). Either route leads to the same destination: the most visited town in Montenegro.
For a half-day, focus on Kotor Old Town alone: Sea Gate, Cathedral of St Tryphon, St Luke’s Square, and the fortress walls if energy permits. For a full day, continue 20 minutes north to Perast and take a boat to Our Lady of the Rocks island.
This is the most popular day out for Herceg Novi visitors and requires no advance planning — just drive and explore.
Practical notes
The Kamenari–Lepetane car ferry: saves 20–30 minutes vs driving around the bay. The crossing takes 10 minutes, runs every 30 minutes in season, and costs about €5 for a car. Worth taking if heading to Kotor, Tivat or Budva.
Passport for Croatia: all visitors need a valid passport to enter Croatia (Dubrovnik, Trsteno). EU citizens can use national ID cards.
Summer border queues: Debeli Brijeg crossing into Croatia can queue significantly in July–August, particularly mid-morning and early afternoon. Crossing before 9:00 or after 18:00 cuts waiting time substantially.

Frequently asked questions
How far is Herceg Novi from Dubrovnik?
Approximately 50 km by road (50 minutes drive without border queues). This is considerably closer than Kotor (90 km) or Budva (120 km), making Herceg Novi the most convenient base in Montenegro for a Dubrovnik day trip.
Can I take a boat from Herceg Novi to Dubrovnik?
Some seasonal boat connections run in summer — check with local operators at the harbour (Škvjer). The crossing is faster than the road and avoids the border queue, but schedules vary by year and are not guaranteed.
Is Mamula Island accessible without a tour?
Not easily — there is no public ferry. You need either a tour operator boat or your own boat hire. Multiple excursion operators run daily trips from the Herceg Novi harbour in season (April–October).
What is the best time to do the Dubrovnik day trip from Herceg Novi?
Leave before 8:00 to arrive before the cruise ships disgorge at 10:00. Return after 18:00 when the same ships have left and the Old Town is a different experience. Avoid the 10:00–17:00 window in peak summer.
Is the Trsteno Arboretum open year-round?
Yes, though hours vary seasonally. In summer, it opens early and closes late. In winter, it is open but the gardens are less colourful. Admission is a small fee, payable on-site.
What is Herceg Novi like as a base compared to Kotor?
Herceg Novi is quieter and less touristy than Kotor, with better access to Croatia and the bay mouth. Kotor gives better access to Lovćen, Skadar Lake, and Budva. For those who want both the Bay of Kotor experience and a Dubrovnik day trip without a 2-hour drive, Herceg Novi is the best balance.
