Perast-Our Lady Of The Rocks &Blue Cave-Private Tour Black Pearl
Kotor Bay looks best from the water. This private Black Pearl tour links Our Lady of the Rocks, the Blue Cave, former submarine tunnels, and a view of Mamula Fortress in roughly three hours. You get the boat to yourself, with room for up to four people and an English-speaking captain to shape the day around your group.
I like the small private setting and the mix of church, military sites, open sea, and swimming time. I also like the freedom to stop for lunch at a Boka Bay restaurant, as one family did at Ribarsko Selo. The main consideration is the price: $346.30 per group is reasonable for four people, but much less attractive for one or two.
I would choose this trip if you want more than a short harbor cruise. You will cover a lot of water, so the speedboat matters. Sea conditions can also affect the pace, and rough water may lead to a changed route or an unplanned lunch stop.

Key points before you book

- Our Lady of the Rocks combines legend, art, and a man-made island in a short visit from Perast.
- The private Black Pearl speedboat carries only your group, up to four people, so you avoid a large shared excursion.
- The Blue Cave includes time for swimming in clear coral water, weather and sea conditions permitting.
- The former Yugoslav submarine tunnel offers a striking military stop that you view by boat.
- Mamula Fortress is a panoramic sight rather than a full visit, so set your expectations accordingly.
- A restaurant stop can be added, with Ribarsko Selo providing a tested option, though lunch costs extra.
Why this private Kotor boat trip works well

Kotor Bay can feel like a place built for a boat. Steep shores frame the water, small settlements line the edge, and historic sites appear one after another along the coast. A private speedboat lets you connect several of them without spending the day waiting for a large group to load and unload.
The plan is compact but varied. You begin with a religious and cultural site, move past a luxury resort, enter a former military submarine tunnel, view a 19th-century fortress, and finish with the Blue Cave. That range gives the trip a stronger sense of place than a simple beach outing.
I especially like the private format for families or friends. A group of four pays one total price, rather than four separate fares, and you can ask for different timing at the stops. Captain Mladen, also referred to as Mland in the tour details, is praised for suggesting good timing and sharing details about the sites. That sort of practical judgment matters on a short trip.
The boat departs from Black Pearl Perast, at Perast 85336. Pickup may be arranged if you share your map location, so confirm that point clearly before the day begins. The tour returns to the same meeting point.

Our Lady of the Rocks and the story of Perast

The first major stop is Our Lady of the Rocks, one of the best-known sights in Boka Bay. The island is artificial, built up over centuries by local believers and sailors. At its center is a church with a story reaching back 573 years.
That background gives the stop more weight than a quick photo opportunity. You are not looking at a natural island that happened to receive a church. You are seeing a place shaped by repeated acts of faith, local tradition, and life on the water.
The visit lasts about 20 minutes. Admission is listed as free, and the tour includes the church and maritime museum. In practical terms, that is enough time to see the main interior and learn why the island matters, but not enough for a long museum study.
I would pay attention to the maritime connection. Perast was tied closely to the sea, and the museum helps link the church to that working coastal world. The island is small, so the visit feels focused rather than tiring.
You should also keep the timing in mind. This is a short stop inside a three-hour outing, not a full church tour or an extended museum visit. If you enjoy art, religious buildings, or local stories, you will likely want to use every minute. If you mainly want swimming and open water, the visit may feel a little structured.
The setting itself is part of the appeal. From the boat, you see the church and island against the wider bay, then return to the water for the next part of the route. That change from quiet cultural site to fast boat ride keeps the tour moving.
A cruise past One&Only and the wider bay
The boat also makes a panoramic pass beside the One&Only resort. This is not listed as a stop with time ashore, so treat it as a view from the water rather than a resort visit.
That distinction matters. The resort gives you a look at the modern luxury side of Boka Bay, while Perast and the older sites show the area’s religious and military past. You will not need to budget extra time here, but it adds another visual contrast to the route.
The speedboat is useful on this stretch. You can cover the bay efficiently and spend more of the three-hour window at the places that require a closer look. On a shared boat, you may have less control over how long the group pauses for views. Here, you can ask the captain about the timing.
Inside the former Yugoslav submarine tunnel

The former submarine tunnel is one of the more unusual parts of the outing. It was a military submarine base used during the period of former Yugoslavia. The boat enters the tunnel, giving you a look at a piece of coastal military infrastructure that is easy to miss from land.
The stop lasts about 15 minutes and admission is free. Do not expect a long museum visit or a fully interpreted indoor attraction. The value comes from seeing the structure in its original setting and understanding how the bay was used for defense.
For me, this is the kind of stop that adds character to the tour. Churches and scenic viewpoints are common parts of coastal excursions. A submarine tunnel is less expected, and it gives you something concrete to remember beyond pretty water.
The tunnel may be less appealing if you want every minute spent in open sunlight. It is a brief military-history stop, so you should think of it as a quick look rather than the main event. Still, the change of mood works well between the elegant bay scenery and the more natural Blue Cave.

Mamula Fortress from the water

The route includes a panoramic view of Mamula Fortress island. The fortress dates from the 19th century, and its position on the island gives it a strong presence from the boat.
The important word here is panoramic. The stated plan is to view Mamula Island and its fortress, not to spend time ashore exploring the fort. You will get the coastal perspective, which is often the best way to understand why a defensive structure was placed there, but you should not book this tour expecting a full fortress tour.
I like this stop because it adds another layer to the route. Our Lady of the Rocks reflects belief and seafaring tradition. The submarine tunnel reflects more recent military use. Mamula brings in 19th-century coastal defense. Together, the stops show how people used the bay for worship, trade, protection, and travel.
Your captain can point out the island as the boat passes. Since the tour is private, this is a good moment to ask questions instead of simply taking photographs and moving on.
Swimming in the Blue Cave

The Blue Cave is the most active part of the tour. You reach the cave by private speedboat, then have the chance to swim in clear coral water and enjoy the cave, nearby caves, and lagoons.
The experience depends heavily on the sea. Light, water conditions, and weather shape the color inside the cave, so the effect will not be identical every day. The tour requires good weather, and the operator may offer another date or a full refund if conditions force cancellation.
Bring a practical attitude to this stop. The Blue Cave is not a controlled indoor attraction with a fixed display. It is a natural place, and the boat captain must work with the conditions on the day. That is one reason a private boat helps: the group can discuss timing and possible stops with the captain.
Swimming is the main reason to bring suitable swimwear and a towel, though those items are not specifically listed as included. The supplied details confirm the chance to swim, but they do not promise a particular amount of swimming time or equipment. Ask before departure if you need to know what is provided.
The cave section lasts about 45 minutes in the stated schedule. That is a useful amount of time for a boat approach, a look inside, and swimming, but it is not an entire beach day. You will also have to account for the rides between the sites.
The Blue Cave is a strong finish because it changes the pace. After the church, museum, tunnel, and fortress view, you can get in the water and simply enjoy the bay. If you prefer sightseeing without swimming, you can still appreciate the boat ride and cave views, but the tour’s design clearly gives the water time a central role.
What the private boat adds

The Black Pearl is a private speedboat for your group, with a maximum of four people. That limit is important. You are not sharing the boat with a large crowd, and you can travel with your own companions throughout the outing.
A private trip does not mean every part is fully customizable. The tour still has a planned route and a limited three-hour duration. But you have more room to discuss timing, ask questions, and request a restaurant stop than you would on a fixed group departure.
Captain Mladen receives particular praise for helping with timing and explaining the sights. One family of four described the trip as a highlight of its holiday, while another party appreciated the captain’s thoughtful response when the sea became rough. In that case, the group stopped for lunch. That is a good example of why a capable captain matters more than a long list of stops.
The boat’s speed is another advantage. The route covers Perast, the outer bay, submarine tunnels, Mamula, and the Blue Cave in about three hours. A slower boat could make that schedule feel rushed. The tradeoff is that a speedboat can feel lively when the water is not calm. If you are sensitive to motion, ask about conditions before setting off.
Price, timing, and value for your group

The price is $346.30 per group of up to four. For four people, that works out to about $86.58 per person. For two people, it is roughly $173.15 each, and for one person it becomes a costly private outing.
I see the strongest value for a family or a group of friends who want privacy. You are paying for the boat, the captain, the flexible feel, and access to several separate places in one outing. The listed admissions are free, but that does not mean the trip is a low-cost sightseeing option.
A restaurant stop can be arranged, with an additional fee for lunch. Ribarsko Selo is one specific option associated with the tour, and it was used to finish one especially successful day. Since food is extra, ask how the stop will affect your time on the water and the final cost.
The tour runs Monday through Sunday from 9 a.m. to 7 p.m. for the stated operating period, from July 18, 2023, through January 15, 2027. The activity itself lasts about three hours. The operator says it is often booked 46 days ahead, so summer dates may need planning.
Pickup is offered if you share your location by map. The official starting point is Black Pearl Perast, and the tour ends there too. Confirm the pickup arrangement rather than assuming the boat will collect you from any address.
Who should choose this excursion?
I would recommend it to:
- A family of up to four that wants its own boat
- Friends who want swimming and sightseeing in one outing
- Couples who value privacy and can accept the higher per-person cost
- People interested in both coastal scenery and military sites
- Anyone who wants to add a flexible lunch stop
I would hesitate if you dislike speedboats, want a long museum visit, or expect to walk through Mamula Fortress. The schedule is active, and the sights are viewed in short bursts. You will spend much of the time moving between places.
This is also not the right choice if your main goal is a full-day beach experience. The Blue Cave offers swimming, but the tour also includes several cultural and historical stops. Its appeal comes from variety.
Weather, cancellation, and simple planning tips
Good weather is required. If poor conditions cancel the outing, you can receive a different date or a full refund. The same applies if the minimum number of participants is not met and the operator cancels.
You can cancel for a full refund up to 24 hours before the start time. Inside that 24-hour window, the payment is not refunded, and changes are not accepted. The cut-off uses local time.
Confirmation normally arrives at booking. If you book within three hours of departure, confirmation comes as soon as possible and depends on availability.
For the day itself, I would bring swimwear, a towel, sun protection, and a phone or camera that you can use safely around water. Ask about pickup, lunch, and what is supplied before you leave. A private boat gives you flexibility, but clear communication helps the captain use that flexibility well.
Should you book the Black Pearl tour?
Book it if you want a private, fast-moving introduction to Boka Bay with a real mix of sights. Our Lady of the Rocks gives you the local story, the submarine tunnel and Mamula add military context, and the Blue Cave supplies the swim and natural spectacle. The private boat and Captain Mladen’s timing advice are the strongest reasons to choose it.
The price makes most sense for four people. For one or two, compare it with a shared boat before committing. Also remember that Mamula is a panoramic stop, lunch costs extra, and the Blue Cave depends on good sea conditions.
For a small group that values privacy, variety, and a chance to shape the day, this is a strong Kotor Bay outing. If you want long visits on land or the lowest possible fare, choose another format.
