Perast-Our Lady Of The Rocks &Blue Cave-Private Tour Black Pearl
Set out from Perast for a fast, varied trip. This private Black Pearl tour packs the best-known sights of Boka Bay into about three hours: the island church of Our Lady of the Rocks, a former submarine tunnel, Mamula Fortress, and the Blue Cave. I like the way the route mixes culture with swimming, and I like having the whole speedboat for your own group instead of sharing the outing with strangers. The main consideration is time. Three hours goes quickly, especially if you want to linger at the church, swim, and stop for lunch.
The tour costs $346.30 per group of up to four, which works out to about $86.58 per person for a full group. That is a fair price for a private boat and captain, but less attractive for one or two people. Captain Mladen, also written as Mland in the tour details, receives special praise for thoughtful timing, useful explanations, and changing plans when the sea becomes rough.

Key points at a glance

- Our Lady of the Rocks: Visit a 573-year-old church and maritime museum on an artificial island in Boka Bay.
- Private Black Pearl speedboat: Your group of up to four has the boat to itself, with a captain who can adjust the timing.
- Blue Cave swimming stop: Swim in clear coral water and explore the cave area when conditions allow.
- Former Yugoslav submarine tunnel: Enter a military-era tunnel built into the coast, a sharp contrast to the bay’s churches and resorts.
- Mamula Fortress view: See the 19th-century island fortress from the water.
- Flexible food stop: An additional lunch stop can be arranged, including at Ribarsko Selo restaurant.
Why this short boat trip works

Boka Bay rewards time on the water. From a road, you see pieces of the shoreline. From a speedboat, the bay opens into a wider picture of mountains, islands, resorts, military sites, and old settlements. This tour uses that view well, moving between places that feel entirely different from one another.
You are not signing up for a long historical lecture or a full-day cruise. The appeal is the combination: a church with an unusual island origin, a military tunnel, a fortress, and a natural cave where you can swim. The route gives you a quick sense of how many layers Boka Bay holds.
The private setup matters. Captain Mladen can suggest the best order and timing for the stops instead of following a fixed group schedule. A family of four can stay together, and a couple does not need to share a boat with a large party. That privacy is one of the strongest reasons to consider this outing.
The boat leaves from Black Pearl Perast, in Perast, with pickup available if you share your map location. The tour ends back at the meeting point. Operating hours are listed as 9 a.m. to 7 p.m., Monday through Sunday, during the stated operating period from July 18, 2023, through January 15, 2027.

Our Lady of the Rocks and its unusual island story

The first major stop is Our Lady of the Rocks, one of the most recognizable sights in Boka Bay. The island is artificial, built up over many years by local people who placed stones and old ships at the site. That origin gives the church more character than a standard island chapel.
The church is about 573 years old, and the visit includes the church and its maritime museum. Admission is listed as free, so the stop adds cultural value without an extra entry charge. You can expect roughly 20 minutes here, which is enough for a focused visit but not a long museum session.
I like this stop because it gives the trip a clear local connection. The island is tied to belief, seafaring, and the daily life of the bay. The maritime museum also helps explain why the church is more than a pretty building in the middle of the water.
The short timing is also the main limitation. If you enjoy religious art, old ships, or small museums, you may want more than 20 minutes. The private format gives you some control, but the tour still has several stops to fit into a three-hour window. Ask the captain early if Our Lady of the Rocks is your priority.
The setting itself is part of the visit. You are surrounded by water, with Perast and the mountains behind you. Even if you only spend a short time inside, the boat approach and island setting make this a memorable opening stop.
Cruising past One&Only Portonovi

The route includes a panoramic cruise beside the One&Only resort. This is not described as a long walking stop, so think of it as a scenic pass by rather than a visit to the resort.
That brief cruise adds a modern note to the outing. One moment you are looking at an old church island and traditional bay settlements. The next, you are passing a polished luxury resort. It is a useful reminder that Boka Bay is both an old maritime region and a present-day holiday destination.
This part is best treated as a view from the boat. You do not need to budget extra time for it, and it helps keep the tour moving toward the military sites and Blue Cave.
Inside the former Yugoslav submarine tunnel

The former submarine tunnel is one of the tour’s most unusual stops. It was a military submarine base from the period when Yugoslavia was a single country. The tunnel was built into the coastline and is approached from the water.
You can expect about 15 minutes here. That is short, but the site does not need a full afternoon to make an impression. Its plain military purpose contrasts sharply with the church, the resort, and the natural cave later in the trip.
I find this kind of stop valuable because it shows a less polished side of the bay. Boka is not only about scenic water and old stone towns. It also has a recent military past, and the tunnel gives you a direct look at that history.
The visit may appeal most to you if you enjoy unusual places and modern history. If you prefer a relaxed cruise with no stark or utilitarian stops, this may feel brief and slightly out of character. That contrast is exactly why it works for many people, though.

Mamula Fortress from the water

The tour then passes Mamula Fortress, a 19th-century fortification on an island. The stop is described as a panoramic view, not a landing and interior visit. You should therefore expect to see the fortress from the boat rather than walk through its walls.
This is an important distinction when you plan your expectations. The island fortress makes a strong photograph and adds another historical layer, but you are not booking a fort tour. The value comes from seeing its position at the entrance to the bay and understanding its role as a defensive structure.
The boat gives you a good way to appreciate the setting. A fortress on an island looks very different from one in the middle of a city. You can take in the walls, the water around the island, and the wider coast without spending time on a long land transfer.
Swimming at the Blue Cave

The Blue Cave is the most playful part of the trip. The boat enters the cave area, where the water can take on a blue glow, and you can swim in clear coral water when conditions permit. The outing also includes other caves and lagoons along the way.
This is where the private boat has a practical advantage. You can tell the captain how much time you want for swimming, within the limits of weather and the overall schedule. The listed time for this portion is about 45 minutes, so you have more than a quick photo stop, but not an unlimited beach break.
Bring the right attitude to the Blue Cave. Natural conditions affect the experience, and the sea must be suitable for the boat and swimmers. The tour requires good weather, and rough water can change the plan. One outing stopped for lunch when the sea became less comfortable, which is a sensible adjustment rather than a failure of the tour.
If swimming is your main goal, tell the captain at the start. If Our Lady of the Rocks matters more to you, say that too. The private format works best when you make your priorities clear instead of assuming every stop will receive equal time.
The cave area also gives the tour its strongest contrast. After the church, museum, tunnel, and fortress, you get a chance to simply be on the water. That mix keeps the outing from feeling like a string of photo stops.
Lunch at Ribarsko Selo

A lunch stop can be arranged at an additional cost, and Ribarsko Selo restaurant was used to finish one particularly successful outing. The meal is not included in the stated tour price, so ask about the arrangement and cost before agreeing to it.
A restaurant stop changes the pace. Without lunch, the three-hour trip is focused on sightseeing and swimming. With lunch, the outing becomes more of a private half-day on the bay, but you will have less time for the listed sights or need extra time added to the schedule.
I would consider lunch if the sea turns rough, if you want a slower finish, or if you are treating the boat trip as a special occasion. I would skip it if your priority is the Blue Cave and you only have three hours.
How the private price adds up

At $346.30 for up to four people, the price is easiest to justify with a full group. Four people pay about $86.58 each, which buys a private speedboat, a captain, pickup options, and a route covering several major sights.
For two people, the same total works out to about $173.15 per person. That is a much bigger decision. You are paying for privacy and flexibility, not only for admission to sights, since the main stops list no admission charge.
The value improves if you care about timing. Captain Mladen has been praised for suggesting good times for each stop and for adapting when sea conditions changed. That sort of judgment matters more on a small private boat than on a large scheduled cruise.
The trip also carries a 5 out of 5 score from 38 ratings, with every rating recommending it. That is a strong signal of consistent satisfaction, especially since the praise focuses on the captain, the private format, the scenery, and the range of stops rather than one isolated feature.
Who should book the Black Pearl?
I would recommend this trip most strongly to:
- A family or group of four that wants a private boat.
- Couples who value privacy and can accept the higher per-person price.
- First-time visitors who want several major Boka Bay sights in one outing.
- People who enjoy a mix of church art, military sites, scenery, and swimming.
- Anyone who wants a captain able to adjust the plan to weather and group preferences.
You may want another option if you prefer a slow, full-day cruise with long visits at each place. Three hours is efficient, but it is not leisurely. You should also think twice if swimming is essential and your schedule cannot tolerate weather changes, since the Blue Cave portion depends on sea conditions.
The tour suits people who like variety. If your ideal boat trip means sitting quietly and watching the shoreline, the tunnel and fortress may feel like extra stops. If you want a fast, well-packed look at the bay, the route makes good use of your time.
Practical advice before you go
Share your exact location through maps if you want pickup. The listed meeting point is Black Pearl Perast, Perast 85336, and the tour returns there at the end.
Wear clothing suitable for a speedboat and bring what you need for swimming. The supplied details do not list specific equipment or onboard facilities, so ask the provider what is available before departure rather than assuming towels or swimming gear are supplied.
Start with a clear plan. Tell the captain if the church, Blue Cave, photography, or lunch matters most to you. The more direct you are, the easier it is to use the private format well.
Keep the weather policy in mind. You can cancel for a full refund up to 24 hours before the start time. Within 24 hours, changes and cancellations are not accepted and no refund is provided. If bad weather cancels the tour, you will be offered another date or a full refund. A minimum number of participants may also apply, even though the activity is private for your own group.
Confirmation is normally received at booking. If you book within three hours of departure, confirmation comes as soon as possible and depends on availability.
Should you book this three-hour Kotor boat tour?
Book it if you want a private, energetic introduction to Boka Bay and your group can fill most of the boat. The route gives you four distinct experiences: an artificial island church, a former submarine base, a fortress view, and a natural cave with time to swim. That is a lot of variety in three hours.
The best reason to choose Black Pearl is the captain’s flexibility. Mladen’s ability to suggest timing and respond to rougher water adds real value, especially when the bay does not behave perfectly. The private setting also lets you shape the pace more than you could on a standard group cruise.
Skip it if you need long visits, guaranteed swimming conditions, or the lowest possible price for a small party. For a group of four seeking scenery, history, privacy, and a bit of fun on the water, this is a well-balanced choice.
