Bay of Kotor boat tours compared: which cruise is right for you?
What is the best boat tour on the Bay of Kotor?
The group large-boat cruise (25–35 EUR/person, 4–6h) is the best value for solo travellers and couples — it covers Lady of the Rocks, Perast, and the Blue Cave in one trip. Book the speedboat option if you have 4–5 people willing to split the cost, want faster transit, and prefer a smaller group. The catamaran is best for a full-day social experience with lunch included.
Getting out on the water: your options explained
The Bay of Kotor is best understood from the water. The mountains that encircle it look highest when you are floating between them. The towns make more sense seen from a boat — Perast’s baroque palaces, the island church of Our Lady of the Rocks, the submarine tunnels at Žanjice — than from the coastal road.
There are four meaningful ways to do this: a large group cruise, a speedboat charter, a full-day catamaran trip, or a sunset/night cruise. Each suits a different traveller and a different day of the week. Here is the honest breakdown.
Option 1: Large group cruise — the reliable crowd-pleaser
Price: 25–35 EUR per person
Duration: 4–6 hours
Departure: Kotor pier (typically 9am–10am)
Group size: 20–50 people
The standard group boat tour is the bay’s most popular experience — for good reason. A converted wooden or fibreglass passenger vessel picks up guests from Kotor (and sometimes Tivat or Herceg Novi), crosses the inner bay to Perast, stops for 30–45 minutes to visit Our Lady of the Rocks island, then rounds the Verige Strait into the outer bay toward the Blue Cave for a swim stop.
Some itineraries also include Mamula Island (the decommissioned Austro-Hungarian fortress, now a hotel), and Žanjice beach — a clean pebble beach on the peninsula south of Herceg Novi. Check what is included when you book: Lady of the Rocks + Blue Cave is the minimum worthwhile itinerary.
What is included: Boat transport, guide narration, swimming stop. Drinks and the island church entry fee (3 EUR) are usually separate.
Pros: Best value per experience. Easy booking. No minimum group needed. Departure from central Kotor.
Cons: Fixed schedule — you cannot linger where you want. Large groups reduce intimacy. Blue Cave swim stop is often busy with multiple boats arriving simultaneously. Alcohol on board costs extra and can get noisy in summer.
Boka Bay Day Cruise (Kotor / Budva / Tivat / Herceg Novi)Option 2: Speedboat charter — fast, flexible, expensive per head
Price: 150–250 EUR for the whole boat (4–6 passengers typically)
Duration: 4–5 hours
Departure: Kotor pier or custom pickup point
Group size: 4–8 people maximum
A rigid inflatable boat (RIB) or fibreglass speedboat takes the same circuit as the group tour but gets there faster, lingers where you ask, and carries only your group. If you have 4–5 people to split the cost, the price-per-head becomes comparable to the group option (40–60 EUR/person) — and the experience is significantly better.
The speedboat advantage is flexibility: your guide can skip Perast entirely and go straight to the Blue Cave if you have seen Perast before, or add the Submarine Base at Žmijanac (a Cold War naval tunnel carved into the cliff) that group tours rarely access.
What is included: Boat and driver/guide, usually snorkelling equipment. Some operators include drinks and snacks for private bookings.
Pros: No schedule pressure. Accessible spots that large boats cannot reach (narrow caves, pebble coves). Best for photography — you can position the boat. Private and quiet.
Cons: Expensive for 1–2 people. Sun exposure is greater on an open RIB. Can be rough in the outer bay in wind.
Kotor: Blue Cave & Lady of the Rocks Speedboat TourOption 3: Catamaran day cruise — the social all-in experience
Price: 50–75 EUR per person
Duration: 7–9 hours
Departure: Kotor or Tivat
Group size: 15–30 people
Catamaran tours are longer and more social than the standard group boat. They typically include multiple swim stops across the bay, lunch on board (often grilled fish, salad, and local wine), and DJ music in the afternoon. Some depart from Porto Montenegro in Tivat and pick up from Kotor on the way out.
The itinerary usually covers Lady of the Rocks, the Blue Cave, Mamula, Žanjice beach (longer stop, 1.5h), and a swimming stop in open water. Lunch is served at anchor, which is the catamaran’s best moment.
What is included: Boat, guide, lunch, often one or two drinks. Swimming equipment varies by operator.
Pros: Full-day experience — you genuinely explore rather than tick boxes. Lunch on the water is memorable. Stable platform compared to RIBs. Good for groups and singles who enjoy socialising.
Cons: Long day — not ideal for people who need to be back for an afternoon commitment. The social atmosphere is not for everyone. Booking further in advance required as catamaran capacity is smaller relative to demand.
Option 4: Sunset and night cruise — cocktails on the inner bay
Price: 25–40 EUR per person
Duration: 2–3 hours
Departure: Kotor pier (typically 7pm–8pm)
Group size: 20–50 people
The night cruise on the Boka (local name for the Bay of Kotor) is a different animal from the day tours. It does not go to the Blue Cave — the outer bay trip is too long for an evening. Instead, it circles the inner bay in the golden hour, stopping briefly at Perast from the water, then returns to Kotor as the fortress walls light up.
Drinks are typically included (wine, beer, prosecco) or available for purchase. Music plays. The sunset light on the mountains is genuinely spectacular in clear weather.
What is included: Varies — some include welcome drinks, others run a cash bar. Confirm before booking.
Pros: Low effort, high visual reward. Good for those who have already done the bay tour in daytime. Excellent for couples. Reliably beautiful in summer.
Cons: Does not cover the outer bay. Weather dependent — overcast evenings are less satisfying. Not suitable for children under 10 in the evening context.

When to book, and what to watch for
All tours operate May–October. July and August bookings should be made 3–5 days in advance — the good operators sell out. The Blue Cave can become congested in peak hours (11am–2pm) regardless of boat type.
Avoid the cheapest operators advertising from the pier on the day. They cut corners on safety equipment, guide quality, and itinerary — the Blue Cave stop becomes a cursory 5-minute float rather than a proper swim. Book through established platforms or directly with reviewed operators.

What the tour covers: a stop-by-stop breakdown
Understanding the stops helps you decide which tour type delivers the most value for your specific interests.
Perast (inner bay)
The first significant stop on most bay cruises is Perast, the baroque village on the inner bay visible as a cluster of bell towers from Kotor. Most tours do not dock in Perast — they pass slowly so the guide can narrate the village history from the water, then stop at the island. This is one of the most beautiful stretches of water in Montenegro: the mountain reflections in flat-calm morning water, the baroque facades, the island church appearing to float.
Our Lady of the Rocks island (Gospa od Škrpjela)
The church built on an artificial island of submerged votive stones and captured Venetian ships is the single most interesting stop on the bay. Locals have added a stone to the reef on every St Mary’s Day for centuries. The interior is covered in ex-votos — silver plaques donated by sailors in thanks for survival. Entry is 3 EUR; budget 20–30 minutes for the visit.
The Verige Strait
The narrow point where the inner and outer bay connect, flanked by the Austro-Hungarian fortress of Mamula and the peninsulas of Lustica and Vrmac. The channel is narrow enough that you can almost hear conversations from the shore. Historical importance: the Venetians stretched a chain across this strait to prevent Ottoman naval entry into the inner bay.
The Blue Cave (Plava špilja)
A sea cave in the outer bay where bioluminescent plankton and the angle of light create turquoise-blue water of extraordinary colour. Swimming inside is the highlight — the light effect is best in morning hours before direct sun enters the cave mouth. All tour types stop here for 20–45 minutes depending on the itinerary.
Mamula Island
The Austro-Hungarian fortress-island built in 1853, used as a concentration camp in World War II (a Montenegrin film, Mamula, documented this history), and now controversially converted into a luxury hotel (Lustica Bay Resort). Most tours circle Mamula without docking. Some speedboat charters include a circumnavigation with historical narration.
Žanjice beach
A clean pebble beach on the Lustica Peninsula, accessible only by boat or a long mountain road. Most full-day tours and catamaran trips include a 1–1.5 hour beach stop here. The water is clear and relatively uncrowded compared to Budva beaches. Good for snorkelling.
Kayaking as an alternative
For those who prefer self-powered water travel, a guided kayak tour from Kotor covers the inner bay — typically the Dobrota shoreline, the Verige approach, and back — in 2.5 hours. The pace is different from a boat tour but the perspective from water level, especially at sunrise, is incomparable.
Bay of Kotor: 2.5-Hour Kayak TourFAQ
Can I book a bay cruise without going to the Blue Cave?
Yes. Night cruises and some Perast-focused day tours skip the outer bay entirely. If you are motion-sensitive or not interested in cave swimming, a Perast and Lady of the Rocks tour is available as a 2-hour focused option.
Is the Blue Cave swimmable in bad weather?
The Blue Cave is in the outer bay, which is exposed to the open Adriatic. In winds above 3–4 Beaufort the tour is typically cancelled or the cave stop skipped. Check weather forecasts the day before. May and June have the most reliable conditions.
What should I bring on a bay cruise?
Sunscreen (essential — the bay reflects UV strongly), a towel, swimwear, cash for drinks and island entry, and a light layer for the return trip in the evening. Waterproof bags for phones on speedboat tours.
Are there cruises that include Mamula Island?
Yes — some group tours and most speedboat charters include Mamula (the Austro-Hungarian fortress island). Confirm it is on the itinerary when booking; not all operators go there.
Can I snorkel in the Blue Cave?
The water inside the Blue Cave is typically 5–8 metres deep and clear. Snorkelling is possible and rewarding — bring your own equipment or rent from the operator. The bioluminescent glow works best before noon.
Do children need tickets for group cruises?
Children under 3 are usually free; ages 3–12 typically get a 50% discount. Confirm with the specific operator. Life jackets are mandatory for children under 12 on all licensed operators.
Is the bay cruise suitable for people who get seasick?
The inner bay (Kotor–Perast–Verige Strait section) is almost always flat calm — the mountains completely shelter it from ocean swell and most wind. The outer bay beyond the Verige Strait toward the Blue Cave is more exposed and can have chop in winds above Force 3. If you are prone to motion sickness, take medication before boarding, sit at the bow or stern rather than amidships, and choose a large-hulled group boat rather than a speedboat (RIBs amplify wave motion significantly more than wooden or fibreglass hulled boats).
Can I book a bay cruise on the day?
In May, June, and October, yes — walk-up availability is usually possible, especially on weekday mornings. In July and August, same-day booking is risky: good operators sell out by 8am, and last-minute spaces are often on lower-quality boats. Book 2–3 days ahead in peak season through a verified platform rather than relying on pier touts.
What is the difference between the Blue Cave tour and the Submarine Base tour?
The Blue Cave tour (Plava špilja) visits a sea cave in the outer bay known for its turquoise bioluminescent water — the standard stop on all bay cruises. The Submarine Base tour visits the Cold War-era naval installation carved into the cliff at Žmijanac — a network of tunnels that housed Yugoslav Navy submarines and was decommissioned after 1991. The Submarine Base is more interesting historically; the Blue Cave is more visually spectacular. Some speedboat charters include both; standard group tours include only the Blue Cave.
