Scuba diving Herceg Novi: wrecks, walls & discover dives in the Bay of Kotor
How much does scuba diving cost in Herceg Novi?
A discover scuba experience (try-dive for uncertified beginners) costs €70–90. Certified single-tank dives run €45–60 depending on site and operator. Full PADI Open Water courses start from €320–380. Most sites are 10–25 minutes by boat from the Herceg Novi waterfront.
Diving inside Europe’s most beautiful bay
The Bay of Kotor is famous above the waterline — but below it, the picture is equally compelling. The bay’s enclosed geography means calm, sheltered diving year-round; its depth (up to 60 metres in the central channel) supports a different ecosystem than the open Adriatic; and its history as a maritime crossroads has left a scattering of wrecks across the muddy bottom that range from Venetian-era timber to 20th-century steel.
Herceg Novi, at the mouth of the bay, has developed into the natural base for diving in the region. Its position — facing both the outer Adriatic and the inner bay — gives divers access to two very different marine environments within the same day trip. Dive clubs here have decades of experience on the local sites and offer everything from first-timer discover dives to technical wreck penetrations.
This guide covers the main dive sites, pricing, what to expect as a beginner or experienced diver, and the practicalities of organising a diving trip from the Herceg Novi waterfront.
The dive sites: what’s down there
The Marquise wreck
The centrepiece of bay diving. The Marquise is an Italian cargo ship sunk during World War II, lying at 38–42 metres on a sandy bottom in the main bay channel. She’s 85 metres long, largely intact, and encrusted with sea life — Mediterranean sponges in orange and yellow colonies, conger eels in the propeller shaft housing, schools of bream circling the bridge structure.
The Marquise is a dive for certified divers comfortable at 35+ metres (Advanced Open Water or equivalent). Visibility on clear days can reach 15–20 metres, and the sheer size of the wreck means you can dive it four or five times and still find new sections. The top of the superstructure comes up to around 28 metres, accessible to Advanced OW divers without technical certification.
Mamula fortress walls
The former Austro-Hungarian fortress island of Mamula sits at the very mouth of the bay. Its underwater base is a vertical wall dropping 20–35 metres, carpeted in gorgonian fan corals and decorated with sponge communities typical of the eastern Adriatic. Visibility here is often better than inside the bay — cleaner water from the Adriatic sweeps past the island regularly.
This is a moderate-difficulty site suitable for Open Water certified divers comfortable with wall diving. The combination of the dramatic fortified island above water and the marine life below makes it a photographic standout.
Mamula also features in Blue Cave and Mamula boat tours for snorkellers — the above-water visit gives divers useful context for the dive.
Kotor: Blue Cave Swim, Lady of the Rocks & MamulaThe Blue Cave (Plava Špilja)
Not a dive site in the traditional sense — the Blue Cave near Mamula is primarily a snorkelling and swimming attraction visited by boat. However, the cave entrance and the reef below it are diveable, and the bioluminescent effect of light entering through the cave floor underwater is unique. Dive clubs sometimes organise cave dives here as a specialty experience; ask specifically.
Underwater walls and reefs near Herceg Novi
Several unnamed but productive dive sites exist within 10 minutes of Herceg Novi harbour: shallow reef plateaus (8–15 metres, ideal for beginners and discover dives), deeper reef slopes with good fish density (16–25 metres), and a handful of anchor chains and old moorings that have become artificial reef structures.
These sites are the workhorses of local diving — consistently diveable, suitable for a range of certification levels, and producing good encounters with octopus, moray eels, scorpionfish, sea bass, and the occasional loggerhead turtle in late summer.
Discover scuba: your first dive
If you have never scuba dived before, a discover scuba experience (sometimes called an intro dive or try-dive) is the right starting point. The Bay of Kotor kayak tour passes directly above some of these same dive sites — useful context for understanding the underwater geography from above before going below. Here’s what to expect:
Pool or shallow-water session (30–45 minutes): You’ll practice breathing through the regulator, clearing your mask, and the basic hand signals. This happens in waist-deep water — no prior swimming experience beyond basic confidence is required.
Open water dive (30–40 minutes): Accompanied by a dive professional (one instructor per 2 beginners maximum), you’ll dive to a maximum depth of 8–12 metres on a sheltered reef. Your instructor is with you the entire time and will manage your buoyancy until you feel comfortable.
The total experience takes about 2.5–3 hours including briefing, equipment fitting, pool session, and the dive itself.
Price: €70–90 per person
What’s included: All equipment, instructor, pool session, open water dive, basic certification documentation
Minimum age: 10 years (PADI Junior Discover Scuba standards); 15 for full Open Water certification
Certified diving: what to expect
For divers holding Open Water certification or above, Herceg Novi offers excellent value compared to western European dive destinations.
| Dive type | Price range | Certification needed |
|---|---|---|
| Single tank, shallow reef (to 18m) | €45–55 | Open Water |
| Single tank, Mamula wall (to 25m) | €50–60 | Open Water |
| Single tank, Marquise wreck (to 40m) | €60–75 | Advanced Open Water |
| Two-tank day trip | €90–120 | Open Water / Advanced |
| Night dive | €55–70 | Open Water + night specialty rec |
Equipment hire: Full kit (BCD, regulator, wetsuit, fins, mask, tank, weights) costs €20–35 per dive when not included in the dive price. Travelling divers who bring their own regulators and BCD pay only for the tank, weights, and wetsuit — ask at booking.
Dive shops: Diving Club Herceg Novi (the longest-established operator) and several independent clubs operate from the waterfront. Standards are generally high — Herceg Novi’s diving community is small enough that reputation matters.
Water temperature and wetsuit guide
| Month | Surface temp | At depth (20m+) | Recommended wetsuit |
|---|---|---|---|
| May | 18–20 °C | 14–16 °C | 5mm full |
| June | 21–23 °C | 16–19 °C | 3–5mm full |
| July–August | 25–27 °C | 20–23 °C | 3mm shortie or full |
| September | 24–25 °C | 22–24 °C | 3mm full |
| October | 20–22 °C | 18–20 °C | 5mm full |
At depth in the Bay of Kotor, a thermocline often drops temperatures 4–6 °C relative to the surface. Divers sensitive to cold should opt for a thicker wetsuit than conditions seem to demand from the surface temperature alone.
Learning to dive: PADI courses in Herceg Novi
Herceg Novi is a practical place to complete a PADI Open Water course. The combination of sheltered bay water for skills sessions and accessible sites for training dives makes the learning environment excellent.
PADI Open Water (OW): 3–4 days, theory + pool + 4 open water training dives. Cost: €320–380. Upon completion you can dive independently to 18 metres with a buddy anywhere in the world.
PADI Advanced Open Water (AOW): 2 days, 5 adventure dives including mandatory deep (to 30m) and navigation dives. Cost: €250–300. Pre-requisite: OW certification.
Both courses are taught in English and Russian by most operators; German and French instruction is available at some clubs.
Best season: May to October
The diving season runs May through October. May and June offer the best visibility (20+ metres on many sites) as winter storms have cleared sediment and summer boat traffic hasn’t yet stirred it. July–August brings warmer water but slightly reduced visibility (10–15 metres) due to plankton blooms and boat traffic. September is widely regarded as the best overall month — warm water, reduced visibility-affecting factors, and significantly fewer dive boats competing for mooring at the best sites.
October diving is possible and quiet, but some smaller operators scale back to weekends only.
Getting to Herceg Novi and organising your dive trip
From Kotor: 45 minutes by road or 25 minutes via the Lepetane–Kamenari car ferry (€5/car, runs every 15 minutes in summer). The ferry route is faster and more scenic — highly recommended over the road route. Once across, Herceg Novi is 20 minutes north.
From Dubrovnik (Croatia): 45 minutes by road. The border crossing at Debeli Brijeg is fast in shoulder season and slower in August peak. Herceg Novi is the first significant Montenegrin town after the border, making it a logical base for travellers arriving from Croatia.
From Budva or Tivat: 1h–1h30 depending on ferry timing and traffic.
Herceg Novi is underrated as a base for a longer stay. Unlike Budva, it’s not dominated by beach-and-club tourism — the old town, the botanical garden (Sub-Tropica Park), and the seafront Šetalište promenade give it a year-round character. For those planning a dive week, basing in Herceg Novi and day-tripping to Kotor and the inner bay is a perfectly practical arrangement.
Non-diving companions can combine beach time at Igalo (the next bay west), the nearby Kanli Kula fortress, and a Blue Cave boat tour that visits the same Mamula dive site from above water. The kayaking tours in the Bay of Kotor depart from Kotor and Tivat — easy enough as a day-trip day off from diving.
Getting to Herceg Novi
From Kotor: 45 minutes by road along the bay coast, or 25 minutes by the Lepetane–Kamenari car ferry across the Verige Strait (€5 per car, runs every 15 minutes in summer). Most divers from Kotor use the ferry.
From Dubrovnik, Croatia: 45 minutes by road (the Croatian border crossing at Debeli Brijeg is fast in the shoulder season, slower in August — allow extra time).
From Podgorica: 1h45 via the Bay of Kotor coastal road.

Frequently asked questions
Can I dive if I wear glasses or contact lenses?
Contact lenses are fine for scuba diving — millions of divers wear them. Prescription diving masks are available from some equipment hire pools; ask when booking. If you don’t wear your contacts and have significant vision impairment, a prescription mask is the only workable solution.
How fit do I need to be to dive?
Recreational diving doesn’t require exceptional fitness, but you should be able to swim 200 metres continuously and tread water for 10 minutes (standard PADI fitness requirement). Conditions that require a medical sign-off include: active asthma, epilepsy, recent ear surgery, or cardiovascular conditions. Obesity alone isn’t a disqualifier; there are weight limits for certain equipment sizes — discuss with your dive centre.
Is the Bay of Kotor safe for diving, given it’s an enclosed sea?
Yes. The bay exchanges water with the open Adriatic through the Herceg Novi mouth continuously. Currents inside the bay are mild (0.1–0.5 knots typically), visibility is acceptable, and the enclosed nature means wave action is virtually absent — a significant safety advantage. The main navigational hazard is boat traffic in the central channel, managed by dive flags and surface marker buoys.
Are there jellyfish in the bay?
Mauve stingers (Pelagia noctiluca) appear occasionally in the Adriatic in late summer. They’re present in the bay from time to time, typically August–September. They cause a mild sting comparable to nettle contact — uncomfortable but not dangerous. Wetsuits provide complete protection.
Can I dive the Marquise wreck as an Open Water diver?
The Marquise lies at 38–42 metres, which exceeds the 18-metre Open Water depth limit. You’ll need Advanced Open Water certification (deep dive specialty). Operators will verify your certification; they won’t take OW-only divers to depth. If you want to see the wreck but don’t have AOW, consider a dedicated AOW course — two days and it’s achievable within a week’s stay.
What other diving exists near Herceg Novi outside the bay?
The outer Adriatic coast north of Herceg Novi has several additional sites, including submerged reefs and a second smaller wreck accessible in calm sea conditions. These are dived less frequently (exposed to swell) but offer good marine life diversity including red coral colonies. Ask at the dive club about conditions.
Combining diving with other Herceg Novi activities
Herceg Novi is more than a dive base. The old town (Stari Grad) is one of the most pleasant on the Montenegrin coast — less visited than Kotor, with a walled fortress, flower-filled stairways, and a relaxed café culture. After a morning two-tank dive, an afternoon walking the fortifications and the Kanli Kula fortress is the ideal recovery.
The Herceg Novi waterfront promenade (Šetalište) runs 2 km along the bay and is the place to spend an early evening — watching the light change on the water, the ferries crossing to Kamenari, and the occasional superyacht navigating out toward the Adriatic.
For non-divers travelling with a diving partner, the Blue Cave and Mamula boat tour covers much of the same geography as the dive route above water — the cave entrance, the fortress island, the bay mouth. It’s a genuine day’s activity without any diving involved.
