Review · BLUE CAVE & GROTTO TOURS
2025 Private Boat To Blue Cave 3 hours ADVENTURE
The best part of this Kotor boat trip is its mix of blue-water swimming and coastal history. In about three hours, you speed across the bay and out toward the Blue Cave, then move from a church-covered island to a former prison and old military tunnels.
I like the chance to book a private boat for up to six people, and I like the variety of the route. Skippers Aki and Bobin are praised for safe driving, music, friendly service, and clear stories. The main caution is that the ride takes up much of the three hours, and rough weather or busy water conditions can prevent swimming inside the Blue Cave.
Key points to know before booking

- Swim at the Blue Cave: You get about 30 minutes for the tour’s main water stop, conditions permitting.
- See four different sides of Montenegro: The route combines nature, a historic church island, a former prison, and military tunnels.
- Private pricing works best for a group: The $241.87 rate covers up to six people, not just one passenger.
- Expect a fast, open-water ride: The journey between stops is part of the experience, but it can feel long or chilly.
- Guides add personality: Aki and Bobin are specifically praised for commentary, safe handling, music, and friendly service.
- Weather matters: Poor conditions can lead to a new date or a full refund, and Blue Cave access can change with traffic or water conditions.
A fast boat ride with four very different stops

This is not a slow cruise around Kotor Bay. It is a short speedboat outing built around several strong sights, with plenty of travel time between them.
You meet at Hawaii Boat Tours Kotor at Park Slobode 1 in Kotor. The activity returns to the same meeting point, making the arrangement simple if you are staying in or near the old town. One booking account also describes pickup from Dobrota, but the official meeting point is in Kotor, so confirm any pickup arrangement before you go.
The tour is private for your group, with a listed price of $241.87 for up to six people. That makes the math quite different for two people than for six. A full group pays about $40 per person, while a couple pays about $121 each. I see the strongest value here for families or friends who want their own boat and can share the fixed price.
The advertised duration is about three hours, including travel time. That detail matters. You are not getting three full hours at the stops. You are getting a compact coastal route with short visits and a fair amount of time on the water.

Blue Cave: the main event in 30 minutes

The Blue Cave is the tour’s headline stop. Its appeal is simple: sunlight enters the cave through the water, creating a striking blue glow. You have about 30 minutes here, and swimming is the main reason to bring a swimsuit.
The water is described as clear, and the stop gives you time to swim near the cave rather than only view it from the boat. If you prefer to stay dry, you can still enjoy the cave’s shape, color, and setting from the speedboat.
Keep your expectations flexible. One outing could not allow swimming in the Blue Cave because of traffic and water conditions. The skipper found another place for passengers who wanted to get in the water, but that alternative does not offer the same cave setting.
This is also the point where weather, wind, boat traffic, and sea conditions matter most. A calm day can make the stop feel magical. A busy or rough day may mean a quick look, a different swimming place, or no swim at all. Bring a swimsuit if you want to use the water, but do not treat the swim as guaranteed.
Our Lady of the Rocks and the view toward Perast

The boat stops for about 20 minutes at Our Lady of the Rocks. This small island in the Bay of Kotor is known for its church and unusual origin story, and the skipper provides background during the visit.
The short stop works well for photos. You can take in the island from the water, see the church up close, and learn why this man-made island became such an important local landmark. Twenty minutes is enough for a taste, not a detailed museum visit.
The route also gives you a panoramic view of Perast from the speedboat. This is a fine use of the ride between stops. From the water, you see the town’s Venetian architecture and shoreline in one view, without spending time walking its streets.
I particularly like this part for first-time visitors to the bay. Our Lady of the Rocks and Perast show the region’s built character, while the Blue Cave supplies the natural spectacle. Together, they keep the trip from becoming just another swim excursion.
Mamula Fortress and a darker chapter

Mamula Fortress is the third stop, with about 10 minutes allotted. The island was used as a prison during World War II, and the skipper shares its story while you are there.
Ten minutes is brief, so think of this as an atmospheric stop and a history lesson rather than a long fortress tour. You will have time to look, photograph the setting, and hear the main story. If you want extensive time inside historic sites, this schedule may feel rushed.
The appeal comes from the contrast. You have just been looking at bright water and a church island. Mamula brings a more serious mood and a reminder that this coast was shaped by military conflict as well as trade, faith, and tourism.
Aki is repeatedly praised for explaining details at the places along the route. Bobin is also described as adding commentary and music, which can make the ride between stops more enjoyable. Since the exact skipper may vary, you should expect a live explanation from the boat captain, but not assume a formal museum-style guided tour.

Former submarine tunnels cut into the mountains

The former submarine tunnels are another quick stop, listed at about 10 minutes. The speedboat enters the old military passages cut into the mountains, allowing you to see their structure from inside.
This is one of the more unusual parts of the route. The tunnels are not polished attractions. Their interest comes from their function, location, and stark appearance. You hear stories about their past while the boat moves into the mountain.
The ten-minute schedule keeps the visit brisk, but it also gives the trip a strong sense of place. You are not only looking at famous viewpoints. You are seeing infrastructure built for military use and hearing how it fit into the coast’s past.
The boat ride itself is important here. A larger sightseeing vessel could show you the tunnel entrance, but the speedboat can take your group farther inside. That makes the stop more immediate, though the narrow setting and changing conditions may limit how long you remain there.
The ride is part of the tour, for better or worse

The boat connects places that are spread along the coast, so travel time is unavoidable. One account describes the route as involving a lot of time riding, even while praising the coastal views and stops.
I would book this for the feeling of moving across the water, not only for the time spent ashore. The ride offers views of the coastline and Perast, and a good skipper can turn the in-between stretches into part of the experience with stories or music.
The tradeoff is comfort. In November, one passenger needed plenty of warm layers. That is sound advice for any cooler day, since speed on open water creates a chill even when the temperature on land feels mild. A windbreaker or warm outer layer is sensible, and you should protect phones and cameras from spray.
The listing gives a private capacity of up to six people, which should be appealing if you want space for your own group. However, one account describes a boat that felt crowded, with 14 people aboard despite an expected capacity of 10. That may refer to a different boat or operating arrangement, but it is worth confirming the vessel and passenger limit when booking if comfort is important to you.
What the skipper adds

The captain is central to this experience. You are moving quickly between several places, and the quality of the commentary affects how much meaning you take from each stop.
Aki receives especially strong praise for safe driving, friendly service, and detailed explanations. One outing continued despite strong wind, with the captain handling the boat safely. Bobin is described as making the trip fun with music and commentary.
The tour is offered in English. You should expect the skipper to explain the sites and tell stories about places such as Mamula and the submarine tunnels. The exact depth and style of the commentary can vary by captain, but the available information points to a personal, informal approach rather than a recorded script.
I like that the same person handles the ride and the interpretation. You can ask a question when something catches your attention, and the captain can adjust the pace or suggest another swimming place when conditions change.
Is $241.87 a good value?

The price is $241.87 per group of up to six. For six people, that is about $40 per person. For four, it is about $60 each. For two, the price becomes much harder to justify unless having a private boat is a priority.
The value comes from combining several outings into one. You get a Blue Cave visit, a swimming opportunity, Our Lady of the Rocks, a Perast view, Mamula Fortress, and former submarine tunnels. You also avoid sharing the entire experience with a large general tour group, at least according to the stated private format.
The short duration keeps the price from becoming a full-day commitment. That is useful if you have limited time in Kotor or want to leave the afternoon open. The drawback is that you are paying for speed and coverage, not long visits at each attraction.
You should also factor in the risk of weather-related changes. The tour requires good weather, and poor conditions can result in another date or a full refund. The Blue Cave swim itself may be changed by water conditions or traffic, so the value is strongest if you care about the whole route rather than only one specific stop.
Who should book this Kotor boat trip?
I would choose this for a group of friends or a family that wants a private day on the water without committing to a full-day cruise. It suits people who like a mix of swimming, photographs, local stories, and unusual military sites.
It also works for visitors who want to see several coastal highlights quickly. The route gives you a useful first look at the bay and nearby coast, especially if you have only a short stay in Kotor.
You may want another option if you dislike speedboats, get cold easily, or need long, unhurried visits. The route is active and efficient, but the stops are short. It is also not ideal if the Blue Cave swim is the only thing you care about, since water and traffic can change the plan.
The experience is generally accessible to most people, and service animals are allowed. It is near public transportation, and confirmation is issued at booking. You should still ask the operator directly about any personal mobility needs, since the provided details do not explain boarding arrangements.
Booking timing and cancellation details
This experience is booked an average of 113 days ahead, which suggests that popular travel dates can fill early. If your schedule is fixed, booking ahead is sensible.
You can cancel for a full refund up to 24 hours before the start time. Changes or cancellations made less than 24 hours ahead are not accepted for a refund. Cutoff times use local time in Montenegro.
If poor weather causes the operator to cancel, you are offered a different date or a full refund. Since wind and water conditions can also affect swimming, check the forecast and contact the operator if the Blue Cave is especially important to you.
Should you book it?
Book this trip if you want a private, fast-moving coastal sampler with a strong mix of water, scenery, and history. The best value comes when five or six people share the price, and the strongest reasons to go are the Blue Cave, the personal skipper commentary, and the chance to enter the old submarine tunnels.
I would not book it solely for a guaranteed swim or a slow historical tour. Conditions can change, and the ten-minute stops at Mamula and the tunnels leave little time for extended exploring.
For a group that understands those limits, this is a smart three-hour use of time in Kotor. Bring warm layers, keep your schedule flexible, and confirm the boat’s passenger capacity before you pay.
