Kotor: Blue Cave & Swimming, Our Lady of The Rocks, Mamula

The Blue Cave is the star here: sunlight slips through the water and turns the cave an otherworldly blue. I like that you also get a real swim, a look at an old submarine tunnel, and a stop at Our Lady of the Rocks, rather than spending three hours only on the boat. I also like the sunset finish over Perast.

The main catch is the boat itself. There is no sun canopy, life jackets are required, and the ride can be rough, so this is not a good fit for anyone with back trouble, seasickness, or limited swimming ability. The cave color can also vary with the hour and weather. A late-afternoon departure may save you from the strongest sun, but the blue may be less dramatic.

Key points to know before booking

• Three hours by speedboat: The circular route starts and ends in Kotor and covers several major Bay of Kotor sights at a brisk pace.
• Blue Cave swimming stop: You get time for photos, swimming, and snorkeling near the cave, with about 20 minutes at the stop.
• Edvan’s careful boat handling: A named guide, Edvan, is noted for reducing the jolts and waiting until other boats moved away before the group took photos.
• A sunset-friendly itinerary: The ride can finish with Perast glowing in the evening light and the Kotor coast lit up after dark.
• Private or small-group format: A boat carrying seven people may feel tight at full capacity, while a smaller party gives you more elbow room.
• $59 includes drinks: Speedboat transport, the listed visits, swimming, and alcoholic and non-alcoholic beverages are included.

A fast ride from Kotor to the open bay

You meet at Park Slobode or Boka Boat Tours, depending on the option you book. Arrive 15 minutes early, since the boat leaves on schedule and the meeting point can vary.

The first leg lasts about 50 minutes. That is a sizable part of a three-hour trip, but it is also where you get the best sense of the Bay of Kotor’s scale. You leave the enclosed bay behind and head toward the Blue Cave area on the Lustica Peninsula. The speedboat makes the transfer much quicker than a slow sightseeing boat, and the wind and spray become part of the experience.

I would wear a swimsuit under light clothing and keep your camera and sunscreen easy to reach. You will be asked to wear a life jacket during the ride. That is sensible, though it can make photography and lounging less comfortable.

Because the boat has no shade canopy, the timing matters. A midday departure means stronger sun on the water and little relief. The 6 p.m. departure taken in July gave one group a cooler ride, a sunset near 8 p.m., and a nighttime return with the coast illuminated. That schedule may not produce the brightest Blue Cave color, but it can make the overall outing more pleasant.

The Blue Cave and its changing blue light

The cave is reached after roughly 50 minutes on the boat. Its blue color comes from sunlight entering the water and reflecting inside the cavern. On a good day, the effect is striking: the water looks lit from below, and the cave walls take on a cool blue glow.

The stop allows about 20 minutes for photos, free time, swimming, and snorkeling. That is enough for a quick swim and a few pictures, but not enough for a slow, extended water session. If swimming is your main reason for booking, keep your expectations realistic. You are getting a short scenic stop within a packed route, not a half-day beach outing.

The cave can be disappointing if the light is not right. Time of day, weather, and the position of the sun all affect the color. One late-afternoon outing found the cave itself less impressive than expected, but the nearby swim, the sunset, and the calm return made up for it. That is useful advice: book this as a complete bay excursion, not as a guaranteed photographic show inside the cave.

You may be able to take a swim in or around the cave, but conditions can affect exactly how the stop works. Bring a towel, swimwear, sunscreen, and a camera. Snorkeling is listed as part of the stop, though the available time is short.

Mamula Island, seen rather than fully explored

After the Blue Cave, the boat runs for about 15 minutes to Mamula Island. The stop lasts roughly five minutes and is mainly for photographs.

Mamula is known for its fortress, which once served as a prison. From the water, you can take in the island’s position at the entrance to the Bay of Kotor and see why the site had military value. The short stop gives you a quick look, not a proper interior visit or a long walk around the island.

That distinction matters. If you want detailed information about the fortress or time on land, this tour does not provide it. If you like a fast-moving route that mixes scenery with brief historical stops, the five-minute photo pause fits the plan.

A wartime submarine tunnel with a quick swim

The next speedboat leg takes about 20 minutes. You then reach a former submarine tunnel for around 10 minutes of photos, a short visit, and swimming.

The tunnel is one of the more unusual stops because it is easy to miss from the open water. It offers a sharp change from the bright cave and broad bay views. Instead of a natural formation, you are seeing a wartime structure cut into the coast, built for submarine concealment.

Again, the clock is tight. Ten minutes does not allow for a long exploration. Think of this as a close look from the boat and a chance to enter or swim near the tunnel, not a museum visit with a detailed presentation. The boat guide is important here, since the value comes from understanding what you are looking at as much as from seeing the dark opening itself.

If you are not a confident swimmer, this portion may be uncomfortable. Non-swimmers are specifically advised not to book the experience. A life jacket is mandatory during the boat ride, but that does not turn the tour into a swimming lesson.

Our Lady of the Rocks and a brief pause in Perast

From the submarine tunnel, you have about 30 minutes by boat before reaching Our Lady of the Rocks in the Bay of Kotor. The stop lasts around 15 minutes and includes time to visit, take photos, and look around.

The island is one of the bay’s most recognizable sights. Its church gives the stop a quiet, reflective quality after the speed and spray of the open-water sections. You can step off the boat, see the church, and enjoy the small-island setting, but 15 minutes is a short visit. If you want a careful look at every church detail, you will need to return separately.

The boat then makes an eight-minute run to Perast. You get about five minutes for photos and a panoramic view. Perast is best appreciated from the water, where its waterfront and stone buildings line up against the surrounding mountains. The stop is brief, but the view works well as the tour’s closing scene.

On an evening departure, the timing can be especially appealing. The sun begins to drop over Perast, and the return trip may show the coast lit up after dark. That final stretch gives the outing a more memorable finish than a simple afternoon transfer.

What the private boat setup really means

The tour is offered as private or in a small group. That flexibility can change the feel of the trip more than the itinerary does.

A private boat gives you the vessel for your own party and lets you share the ride with your chosen companions. For couples or families who want control over the mood, that is a meaningful benefit. You are not locked into the habits of a large sightseeing crowd.

The boat can carry up to seven people, but seven may feel cramped. A group of four had noticeably more space, and that size seems better for taking photos, moving around, and settling in during the long speedboat stretches. If you are booking privately, the price is easier to justify when divided among several people.

The boat has no canopy, so the tradeoff is clear: you get an open view and plenty of wind, but no built-in shade. Bring a hat and sunscreen. If you dislike spray, noise, or a firm ride, a slower covered boat may suit you better, even though it will not cover the same route in three hours.

The handling of the boat also matters. Edvan is specifically noted for driving with care and reducing the shaking where possible. He also waited until other boats had left after the Blue Cave swim, allowing a quieter photo session and better sunset views. That kind of timing can make a crowded attraction feel more relaxed.

Is $59 a fair price?

At $59 per person, this is a strong-value outing if you want several Kotor-area sights in one short trip. The price includes the speedboat ride, Blue Cave access, swimming, the submarine tunnel, Mamula, Our Lady of the Rocks, the Perast view, and alcoholic and non-alcoholic beverages.

The value comes from the coverage. In three hours, you reach places that would be difficult to combine on foot or by ordinary road transport. You also avoid paying separately for a boat transfer between each bay stop.

The price is less compelling if your priority is depth. Mamula receives only about five minutes, the submarine tunnel about 10, Our Lady of the Rocks about 15, and Perast about five. You are paying for a broad, fast route, not long visits at each place.

For a private group, $59 per person can be particularly appealing. For a full boat, you should decide if the seven-person capacity feels comfortable. For a solo booking, a small-group option may offer a better balance between cost and space.

The booking terms are useful for uncertain weather. You can cancel up to 24 hours before departure for a full refund, and reserve now while paying later. The tour can be cancelled or moved if weather makes the sea unsafe, so keep some flexibility in your Kotor plans.

Who should book this Kotor boat tour?

I would choose this tour if you want a compact introduction to the bay, especially if you have only a short stay in Kotor. It suits people who enjoy fast boat rides, quick photo stops, swimming, and a mix of natural and historic sights.

It is also a good choice for an evening outing. The late-July timing described above avoided the worst midday heat and added sunset and nighttime coastal views. The Blue Cave may not glow at its strongest late in the day, but the wider experience can be more comfortable and atmospheric.

You should think twice if you have back problems, get seasick, or dislike open boats. The route includes long stretches at speed, and there is no shade canopy. Children under two are not accepted, and the tour is not suitable for non-swimmers.

Bring a hat, swimwear, towel, camera, and sunscreen. Smoking is not allowed. Wear footwear that you can manage around a wet boat and be ready to follow the guide’s instructions around the cave, tunnel, and swimming areas.

Should you book it?

Book it if you want many highlights in three hours, value a small or private boat, and like the idea of ending with Perast at sunset. The strongest parts are the speedboat ride, the chance to swim, the unusual submarine tunnel, and the careful handling described from Edvan.

Do not book it expecting a long visit at Mamula, a full church tour, or a guaranteed electric-blue cave every time. The route moves quickly and the cave depends on light. For an active, scenic sampler of Kotor Bay at $59, it is a practical pick. For a slow cultural tour or a shaded cruise, choose something less exposed and less hurried.
