Kotor: Boat Cruise with Blue Cave Swim and Submarine Base

The best part of this Kotor speedboat cruise is its mix of scenery, swimming, and history. In three hours, you zip past Perast, Tivat, Porto Montenegro, and Herceg Novi, then stop at a blue-lit cave, a former wartime prison, an old submarine base, and the tiny island of Our Lady of the Rocks.

I like the fast pace and the useful variety. Guides such as Peter, Andre, Marco, and Marko are praised for explaining the sites clearly and helping nervous swimmers. I also like that the boat carries water, snorkel masks, life-saving gear, Wi-Fi, music, a fridge, and shade.

The main thing to consider is that swimming inside the Blue Cave is not guaranteed. When several boats crowd the entrance, your captain may take you to a nearby cove instead, often with clearer water and more room. That is still a good swim, but it is worth knowing before you book.

Key points before you book

• Three hours, many sights: You cover Our Lady of the Rocks, Mamula Island, the Blue Cave area, and former submarine tunnels in one compact outing.
• Fast, open-air transport: The speedboat cuts across the bay quickly, with music, shade, Wi-Fi, and a fridge onboard.
• Swimming is part of the trip: Bring swimwear and a towel. Snorkel masks and life-saving equipment are included.
• History adds weight: Mamula was turned into a concentration camp during World War II, while the submarine tunnels were built by the Yugoslav Army.
• Our Lady of the Rocks costs extra: Church entry is €2 per person and is not included in the $56 price.
• Best for active sightseers: The tour is not suitable for wheelchair users, and parking in Kotor can be very difficult.

Why this three-hour cruise works so well

Kotor Bay is easy to admire from shore, but the water gives you a much broader view. A speedboat lets you see the bay’s steep mountain walls and coastal settlements without spending half a day on transport.

At $56 per person, this is good value if you want several major sights and a swim in one morning or afternoon. A private boat would cost far more, while a slower boat trip may not reach as many places in three hours. The tradeoff is simple: you get a lively, tightly timed outing rather than a quiet, lingering cruise.

The boat ride itself is part of the fun. You feel the rush as the captain opens the throttle between stops, with wind and sea spray taking the edge off hot weather. On very warm days, the shaded seating matters. On cooler days, especially in October, bring a coat. One October visitor found the noon departure chilly on the water, so do not judge the temperature only by what you feel in Kotor’s old town.

The boats are described as clean, new, comfortable, and spacious. Capacity can reach 22 people, though some departures have only six to eight passengers. That makes a real difference. A small group feels more personal, and the captain can often adjust the order of the stops to avoid the worst crowds.

Meeting near Kamelija and leaving Kotor

You meet at the MontenegroGlobe agency near shopping center Kamelija, a few minutes from Kotor’s old town and the Port of Kotor. This is a practical location if you are staying inside the old town or arriving by cruise ship.

Give yourself time to find the office and walk to the boat. Parking in Kotor is notoriously difficult, so driving in for the tour is not the easy option. Some guides have collected people from hotel jetties or nearby accommodations, but that is not the standard meeting arrangement. Ask before assuming a pickup is available.

Once aboard, you receive a bottle of water and safety equipment. The boat has a fridge, music, onboard Wi-Fi, and shade. These are small comforts, but they make the fast ride easier, especially when the sun is strong or you are carrying phones and cameras.

The tour runs in English with a live guide. Captains including Peter, Andre, Marco, Marko, and Andreas have been singled out for friendly service, clear explanations, and attention to safety. The individual captain can shape the mood of the trip, so expect a mix of local stories, jokes, music, and practical help rather than a formal lecture.

Our Lady of the Rocks and the view toward Perast

The first major stop is Our Lady of the Rocks, the artificial island opposite Perast. Local fishermen began creating the island in the 15th century, adding rocks and sinking old boats loaded with stone. The result is one of the most unusual cultural sights in the bay: a small island with a church rising from the middle of the water.

You have about 20 minutes for the stop. That is enough to walk around, take photographs, and enter the church if you choose. Church admission costs €2 per person and is paid separately.

Inside are 68 paintings by Tripo Kokolja, a noted 17th-century Baroque artist from Perast. The island is small, so the appeal is not a long visit. It is the combination of the church, the water, and the story of how people built an island by hand.

This stop also gives you one of the tour’s best photo opportunities. From the boat, you can frame the church, Perast, and the surrounding mountains together. Keep your camera ready as you pass the waterfront towns. Perast is especially photogenic, with its old stone buildings and compact shoreline.

The short time here is both a strength and a limitation. You see the essential points without losing too much of the three-hour schedule, but anyone wanting a slow museum visit should return separately.

Speeding past Tivat, Porto Montenegro, and Herceg Novi

Between the stops, the boat becomes a moving lookout point. You pass coastal towns and marinas including Tivat, Porto Montenegro, and Herceg Novi. The captain may point out landmarks and explain the setting as you travel.

This is where the speedboat format earns its price. You are not simply looking at one section of Kotor Bay. You travel farther into the wider bay and out toward the open water, seeing how the small towns change from old stone settlements to modern marinas and waterfront resorts.

The ride can be lively. Music plays onboard, and the speed brings a burst of excitement each time the boat accelerates. If you prefer a quiet, slow cruise, this may feel too energetic. For most people, though, the contrast between calm photo stops and quick crossings keeps the outing from dragging.

Sit where you can see forward if you enjoy the speed. Sunglasses are essential, and a camera strap or secure bag is sensible. The boat is comfortable, but this is not a polished indoor excursion. You are exposed to wind, spray, and changing temperatures.

Mamula Island and a difficult wartime past

Mamula Island is a brief but serious stop. You spend about 10 minutes near the island, usually taking photographs while the guide explains the fortress.

The fortress was built to protect the entrance to the Bay of Kotor. During World War II, the Italians converted it into a concentration camp. That history gives the stop a darker tone than the bright sea and postcard scenery might suggest.

You do not get a long land visit here. The value is in hearing the story from a local skipper and seeing the fortress in its island setting. The short stop also means the tour does not become too heavy. You acknowledge the past, take in the structure, and continue toward the swimming portion.

I appreciate this kind of historical context. A boat trip made up only of pretty views can feel thin. Mamula reminds you that the bay has been shaped by military power, occupation, and imprisonment as well as fishing and tourism.

The Blue Cave area and the best swim

The Blue Cave is the tour’s headline stop. Sunlight enters through the cave opening and reflects through the water, giving the rock interior a blue glow. You get about 25 minutes for swimming and snorkeling in or near the cave.

Here is the practical detail that matters most: the boat may not let you swim inside the cave. When other boats fill the entrance, captains sometimes take you to a nearby secluded cove, where you can swim in clear water without being squeezed among boat traffic. The cave remains a photo stop, while the nearby water becomes the safer and more enjoyable place to get in.

That arrangement can actually improve the experience. Several people have found the nearby swimming area clearer, calmer, and better for seeing fish. Snorkel masks are supplied, so you can look beneath the surface without bringing your own equipment.

Non-swimmers are not automatically left out. Guides have provided life jackets and helped people climb back aboard, with Andre receiving particular praise for checking on nervous swimmers and taking photos. Still, you should be comfortable around open water or tell the guide early if you need extra help.

Bring your own towel, swimsuit, and sunglasses. You receive a bottle of water, but food and extra drinks are not included. A dry bag is useful for phones, though no dry bag is listed as part of the equipment.

The Blue Cave can be busy in high season. An adaptable captain may switch the order of the swimming stop and the cave visit, giving you a better chance of seeing the cave with fewer boats. This is one reason a live guide matters more here than on a fixed sightseeing route.

Former submarine tunnels built by the Yugoslav Army

On the return route, the speedboat stops near the entrances to former submarine tunnels. The Yugoslav Army cut these narrow shelters into the rock so military submarines could hide from view.

You spend only about five minutes here, usually taking photographs from the boat. That is enough to understand the basic purpose and see the stark openings in the shoreline, but not enough for a detailed military tour.

The tunnels are interesting because they are easy to miss from land. From the water, you see why the location worked: the entrances blend into the rocky coast, while the narrow passages gave submarines cover. This is a quick stop, but it adds another layer to the bay’s past.

Afterward, the boat makes the final run back to Kotor. The return crossing gives you one last chance to enjoy the coastline without needing to navigate roads or find separate transport.

What the guides add to the experience

The guide can make or break a short boat trip. With only three hours, you need someone who can explain a place in a few useful sentences, keep the schedule moving, and help with the practical parts of swimming and boarding.

The strongest guide feedback centers on Peter, Andre, Marco, Marko, Andreas, and Igor. Their strengths include clear English, local stories, friendly humor, and careful attention to people who are nervous on the water. One captain extended the outing briefly when a storm arrived, taking the group to a beach for shelter and providing raincoats afterward.

That kind of flexibility is valuable, but weather decisions belong to the captain. High waves can change the route or timing, and the company can cancel if conditions are poor or if too few people book. Free cancellation is available up to 24 hours before departure, and you can reserve now while paying later, which helps if your schedule is unsettled.

One uncomfortable incident occurred at the agency, where a customer felt singled out because of her race. The guide later responded empathetically, but the incident understandably affected her view of the experience. I would keep that in mind when deciding how much weight to give the otherwise strong service record.

Who should book this Kotor boat trip?

I would choose this tour if you have only a short time in Kotor and want a broad sample of the bay. It suits couples, solo visitors, families with older children, and small groups who enjoy a bit of speed and want swimming included.

It is also a good choice for solo visitors. The shared boat makes it easy to meet other people, while a small departure group can still feel relaxed. If you are worried about swimming, tell the guide at the start and use the provided life-saving equipment.

I would not choose it if you need step-free access, dislike fast boat rides, or want extended time at each historic site. It is not suitable for wheelchair users or people over 95. Pets and bikes are not allowed.

Final verdict: good value for an active half-day

Yes, I would book this tour for a first visit to Kotor, especially if you want scenery and activity rather than a long museum visit. For $56, you get transportation, a bottle of water, a snorkel mask, safety equipment, a live English-speaking guide, and access to several of the bay’s most memorable sights.

Book a morning departure if you want cooler conditions, or choose noon in October when the air may be warmer, but bring a coat for the boat. Expect the Blue Cave swim to happen nearby if the cave is crowded, and you will be less likely to feel disappointed.

The tour is short, quick, and well packed. Its best moments are the glowing cave entrance, the clear water around the swimming cove, the sudden rush of the speedboat, and the quiet sight of Mamula’s fortress. If those sound better than sitting on shore all day, this is money well spent.
