REVIEW · BLUE CAVE & GROTTO
Risan: Blue Cave, Our Lady Of The Rocks – Pick Up
The best part of this 150-minute speedboat trip is the variety. In one short outing, you see old churches, grand bay scenery, military tunnels, a former prison island, luxury marinas, and the Blue Cave, where you can swim in naturally blue water. I like that the route is not just a ride to one attraction. It gives you several very different views of the Bay of Kotor.
I also like the practical format. The boat starts and ends at Risan, drinks are included, and private or small-group options are available. A boat holding up to eight people has been used on this tour, which makes the ride more personal than a large sightseeing vessel. The main drawback is time: stops are short, and wind, engine noise, or loud music can make the guide difficult to hear.
Key points to know before booking

- The Blue Cave includes a 25-minute swim stop: Bring swimwear, a towel, sunscreen, and a camera that can handle splashes.
- Our Lady of the Rocks is the first proper visit: You have about 20 minutes to explore and take photos, but the church entrance ticket is extra.
- The route mixes nature, history, and modern Montenegro: You pass Porto Montenegro, Porto Novi, submarine tunnels, and Mamula Island.
- This is a fast speedboat tour: Expect roughly 60 minutes of travel between stops, with wind and spray possible.
- A small boat makes the trip more intimate: Private and small-group departures are available, with a reported maximum of eight people on one boat.
- The cave can be crowded: Boats may gather inside, and that can affect the quiet atmosphere and the clarity of the guide’s explanations.
Why this short boat trip covers so much

At $51 per person, this tour is priced as a compact way to see a wide stretch of the Bay of Kotor. You are not paying only for a swim. The fare includes the speedboat, an English-speaking guide, the main stops, free water and juices, and the return ride to Risan.
That matters because the route covers several places that are spread around the bay and beyond its narrower inner reaches. Arranging all of this yourself would require separate transport and boat planning. The value is strongest if you want a quick survey of the area and do not have a full day available.
The trade-off is the pace. This is not a slow cruise with long time at every stop. You get photo opportunities and brief visits, then return to the boat. I would choose it for variety and easy transport, not for long museum visits or a quiet afternoon on the water.
The tour is available as a private or small-group experience. Group size will affect how much room you have on board and how easy it is to hear the guide. If your booking uses a boat with up to eight people, you should have a more relaxed setup than on a large shared cruise, though the ride can still feel active when the boat reaches open water.

Leaving Risan by speedboat

The Port of Risan is both the starting and ending point. The exact meeting point can vary with the option you book, so check your confirmation carefully before setting out.
The first 10 minutes are spent on the boat. This gives you a quick look at the bay before the first stop, but it also tells you what kind of outing this is. The boat is built for speed and efficient transfers, not for a long, silent cruise. Wear clothes that can handle spray and shoes suitable for water activities.
Risan is in the Bay of Kotor, an area known for old churches, palaces, and steep coastal scenery. From the water, you get a different angle on those buildings and the shoreline. Keep your camera ready during the transfers, since the views are part of the experience even when the boat is moving between stops.
If you are prone to seasickness, this may not be the right choice. The tour information also advises against it for people with back problems. That is worth taking seriously because a fast boat can make the ride lively, particularly when the water is rough.
Our Lady of the Rocks and the 20-minute stop

The first major stop is Our Lady of the Rocks near Perast. This small island is one of the most recognizable sights in the bay, with its church and unusual setting on the water.
You have about 20 minutes here for a visit, photos, and free time. The guide provides information about the island, so this is the point where you get some context rather than only a quick look from the boat. I would use the time first to understand the setting, then take photos, since the stop moves quickly.
The entrance ticket to the Church of Our Lady of the Rocks is not included. You can still enjoy the island and its views without paying for entry, but budget for the extra ticket if seeing the church interior is important to you. The short stop means you should not expect an extended visit.
This is also a good early photo stop because you are still fresh and dry. Later, after the Blue Cave swim, you may be more focused on getting changed and keeping your belongings dry.
Through the Verige channel toward Porto Montenegro

After Our Lady of the Rocks, the boat continues for about 20 minutes. The route passes through the Verige channel, one of the narrower passages in the Bay of Kotor.
The channel helps you understand the shape of the bay. Instead of seeing only broad water and distant shorelines, you move through a tighter stretch where the surrounding coast feels closer. The boat ride is a useful part of the tour here because it connects the older sights around Perast with the newer marina districts farther along the route.
You will see Porto Montenegro and Porto Novi, two luxury marina areas. Their polished buildings, yachts, and waterfront design offer a clear contrast with the old churches and historic structures earlier in the day. I like this change of mood because it shows that Montenegro is not only about medieval towns and rugged coastlines. Modern resort development is part of the country’s present-day identity too.
The tour does not provide a long stop at either marina. You mainly see them from the water, so think of this section as a scenic pass-by rather than a shopping or dining visit.

The former submarine tunnel and its wartime story

The next stop is an abandoned submarine tunnel connected with World War II. The boat pauses for about 10 minutes for photos.
These tunnels were built to hide submarines, and their dark openings cut into the coast give the route a more serious edge. You do not enter the tunnels as part of the stated program. Instead, you see them from the boat and hear about their purpose.
I find this stop valuable because it breaks up the pretty scenery. The bay has churches, palaces, and marinas, but it also has military remains and reminders of conflict. Ten minutes is enough for a look and a few photos, though not enough for a detailed exploration.
If you want a long land visit at historic sites, this tour will feel brief. If you enjoy seeing unusual places from the water, the tunnel makes the ride more varied.
Passing Mamula Island, Montenegro’s former prison
The boat then travels for about 15 minutes to Mamula Island. You stop for around 10 minutes to take photos.
Mamula was once a prison, and it is often compared with Alcatraz because of its isolated position. From a boat, you can appreciate why an island location made escape difficult. The stop is mainly observational, so you should expect to see the island rather than tour its buildings.
This part of the trip gives you another change in tone. After the modern marinas and the submarine tunnel, Mamula adds a former prison to the route. It is a useful reminder that the bay is not simply a scenic setting. Its position has made it important for trade, defense, travel, and settlement over many centuries.
Again, the timing is tight. Ten minutes works for a photo stop, but you will not have time for a long walk or a detailed visit. Keep your camera ready and listen when the guide explains what you are seeing.
Swimming inside the Blue Cave

The Blue Cave is the main event for many people. After another 15-minute speedboat ride, you have about 25 minutes for a visit, photos, free time, and swimming.
Sunlight enters the cave through an underwater opening, creating the famous blue color inside. The effect can change with the light and water conditions, so do not expect exactly the same shade every day. When the boat is inside, the water can look especially bright, making this the strongest photo stop of the tour.
You can swim in the cave, which is a major reason to bring swimwear and a towel. The swim is not an optional extra listed separately, so plan on getting into the water if conditions allow. Bring sunscreen and keep your camera secure, since the boat and cave environment are wet.
There is one practical catch: the cave may have several boats inside at once. That can make the space noisy and reduce the sense of calm. Wind can also make it hard to hear the guide, and loud music has been a problem on at least one outing. If clear narration matters to you, stay close to the guide when possible and ask questions during a quieter moment.
You should also know that the stop comes near the end, followed by a 40-minute boat ride back to Risan. The crew may not provide much time to change after swimming. One passenger specifically found that there was no time to get changed before the return journey, so wear a swimsuit under your clothes and pack a quick-dry layer.
What the 40-minute return ride feels like

The longest single boat transfer is the ride back to Risan. After the Blue Cave, you spend about 40 minutes on the speedboat before arriving at the port.
This return leg is useful for taking in the bay again, but it can feel long if you are wet, cold, or tired. A towel and an extra layer are sensible. The boat provides free water and juices, which helps, but the tour does not list a meal or substantial snack.
Weather can affect this part of the outing. The operator advises you to be ready for changes in conditions and to follow the guide’s safety instructions. Wind, spray, and sun can all make a difference, so a hat, sunscreen, and comfortable clothing are more than packing suggestions.
The experience is scheduled for 150 minutes, though one reported departure lasted about two hours. Allow some flexibility rather than arranging an immediate connection after the advertised finish.
Group size, guide, and comfort

The tour is conducted in English and can be booked privately or in a small group. A speedboat used for one departure held a maximum of eight people. That size is a good fit if you want direct access to the guide and less crowding than a large boat.
The guide’s explanations cover Our Lady of the Rocks, the tunnels, Mamula, and the other sights along the route. The quality of the experience will depend partly on where you sit and how busy the cave is. Wind and engine noise are natural limits on a speedboat, and music can make them worse.
The physical demands are modest but real. You need to board a boat, sit through fast transfers, and manage a swim stop. The tour is not suitable for people with back problems or those prone to seasickness. Pets and smoking are not allowed.
The current score is 4.6 out of 5 from 33 ratings, which fits the overall picture: the route is widely appealing, but comfort and timing can vary with weather, crowding, and the pace of the day.
What to pack for this exact route
Keep your bag small and practical. You will be moving between boat travel, photo stops, and a swim, so anything bulky becomes a nuisance.
Bring:
- A hat and sunscreen for the open boat
- Swimwear and a towel
- Comfortable clothing and water-suitable shoes
- A camera or phone for the church, tunnels, island, marinas, and cave
- An extra layer for the return ride
- A small dry bag or other protection for electronics
Wear your swimwear under your clothes if you do not want to change on the boat. Since the schedule may leave little time after swimming, this simple choice can make the final 40-minute ride much more comfortable.
Who should book this Risan boat tour?
I would book this tour if you have limited time and want several of the bay’s best-known sights in one outing. It suits anyone who wants a swim, quick historical context, and plenty of views without planning separate transport.
It is also a good match for couples, friends, and small families who prefer a speedboat to a large sightseeing vessel. The small-group option is especially appealing if you value a more direct experience with the guide.
I would think twice if you want long visits at each stop, dislike fast boats, or need a quiet cave visit. The Blue Cave may be crowded, the commentary may be hard to hear in wind or music, and the return trip comes soon after the swim.
At $51, the tour offers fair value for the amount of ground it covers, especially with drinks and the return ride included. Just remember that the church entrance is extra and the schedule favors variety over lingering.
