Kotor: Red Semi-Submarine Family Tour With Underwater Cabin
Kotor’s red semi-submarine gives you two views of the bay in one short trip: wide panoramas from the open deck, followed by a look beneath the surface through four glass windows. You pass stone villages, churches, old palaces, and steep cliffs before sitting below the waterline as the bay turns quieter and more enclosed.
I like the easy one-hour format, which fits neatly into a day in Kotor, especially if you are visiting from a cruise ship. I also like the child-friendly setup, with small life jackets available and a skipper who may let children help steer when conditions and group size allow.
The main thing to understand is that this is not a full submarine expedition or a reliable wildlife trip. You might see sea grass and a few small fish, but murky water, boat traffic, and the season can limit the view below the surface.

Quick points before you book

- Two-part route: Spend about 20 minutes on deck, 20 minutes in the underwater cabin, and 20 minutes on deck for the return.
- Rare viewing angle: The cabin has four bullet-proof glass windows, two on each side, looking below the waterline.
- Strong family appeal: Children can request child-size life jackets, and the skipper may let them pilot the boat for a short time.
- Excellent location: The meeting point is in City Park, only 200 meters from Kotor’s Old Town gate and close to the port.
- Good short-trip value: At $35 per person, this works best as a compact sightseeing activity rather than a major marine adventure.
- Wildlife is uncertain: Expect scenery for certain, but treat fish sightings as a bonus.
Starting beside Kotor’s Old Town

The boat leaves from City Park, at Park Slobode 1. This is a useful meeting point because it is only about 200 meters from the Main Gate of Kotor’s Old Town and within easy walking distance of the port.
If you arrive by cruise ship, leave the ship and pass through security. Turn left, then turn left again at the small bridge toward the park. Near the waterfront, look for the information desk, where the skipper and a staff member wait for the group.
Arrive at least 30 minutes early. That advice matters here because the park area can see heavy traffic, and roadwork on the main road may slow cars. If you are driving, allow extra time rather than trying to arrive just before departure.
This is not a hotel pickup service. You make your own way to the park, and the tour returns to the same place. That makes it simple to combine with Old Town sightseeing, though you should avoid bringing large bags or luggage. Pets are not allowed, and smoking is not permitted on the boat.

The first 20 minutes: Kotor Bay from the open deck

The trip begins above the water. From the open deck, you get the broadest views of Boka Bay, including the steep mountain walls that make Kotor such a striking place to visit.
The boat moves along the coast at an easy pace. That gives you time to point a camera toward the stone villages, small churches, historic palaces, and rocky slopes rising straight from the water. You are not simply looking out at open sea. The shoreline remains the main attraction.
I would use this first section to get your bearings and take wide photographs. The upper deck provides the clearest views of the bay and the best chance to follow the shape of the coast. A tent provides shade on sunny days, which is useful during the warmer months.
The skipper also acts as your English-speaking guide. The guiding style can include stories about local points of interest and the area’s past. One particularly enjoyable possibility is being invited to help steer the boat. This has happened when groups were small, and children have especially enjoyed it.
Do not count on this as a guaranteed part of every departure. It depends on the skipper, the group, and operating conditions. Still, it adds a personal touch that a standard sightseeing cruise may not offer.
The underwater cabin and its four windows

After the first portion on deck, you move into the underwater cabin. This is the feature that gives the tour its name and its appeal.
The cabin has four large bullet-proof glass windows, with two on each side. As the boat continues forward, you can watch light move through the water and see changing shades of blue and green below the surface. The view feels more enclosed and film-like than the open deck, even though you remain close to the coastline.
The cabin is best understood as a short underwater viewing room, not a true submarine journey. You do not go far offshore or spend the whole hour below the surface. The boat follows a simple route, and the cabin section lasts about 20 minutes.
Marine life is the uncertain part. You might see sea grass, small fish, or something that passes quickly beyond the glass. On some outings, the water can be cloudy and visibility may be poor. Boat traffic in the bay can also affect water conditions.
This is why I would book the cabin for the unusual viewpoint, not for guaranteed animal sightings. If you see fish, enjoy the moment. If you do not, the trip still offers a view of Kotor Bay that you cannot get from a regular open boat.
The final 20 minutes: back above the water
The last 20 minutes are spent on deck during the return to City Park. This gives you another chance to photograph the coast, but the light and angle may look different from the outward journey.
You can use this section to revisit places you noticed earlier, listen to more local stories, or simply relax under the deck tent. Chilled drinking water is provided, which is a small but welcome detail on a sunny day.
The return also helps balance the tour. The underwater cabin is the novelty, but the open-deck portions provide most of the visual drama. You get cliffs, villages, churches, and the bay’s broad shape rather than a limited view through glass.
The boat comes back to the same departure point, close to the Old Town and cruise port. That makes it easy to continue your day without arranging another transfer.

What makes the scenery worth your time

Kotor Bay is a place where the setting does most of the work. The water reaches deep into the surrounding mountains, and settlements appear in narrow strips along the shore. From a boat, you see how the villages, churches, and old stone buildings fit between the water and the cliffs.
A road or walking tour gives you a close look at individual buildings. The semi-submarine gives you distance and movement. You can watch the coastline unfold rather than seeing one view at a time.
The Old Town scenery is another reason to keep your camera ready. The boat does not replace a proper visit to Kotor’s historic center, but it gives you a waterfront perspective that you cannot get while walking behind the city walls.
The route is also useful if your schedule is tight. An hour is long enough to get on the water and short enough to fit before or after a visit to the Old Town. For a cruise stop, that compact timing is a real advantage.
Is $35 a fair price?

At $35 per person, the tour is reasonably priced if you value a short, unusual activity with a guide and a family-friendly format. You receive the boat ride, the open-deck views, the underwater cabin, drinking water, safety equipment, fuel, insurance, and an English-speaking skipper.
The value depends on what you want from the hour. If your main goal is to see Kotor Bay from the water, the price is easy to justify. If you are paying mainly for marine life, the value becomes less certain because fish sightings are limited and visibility changes.
I would compare it with a standard speedboat trip in terms of purpose, not just cost. A speedboat may cover more ground and reach additional sites. This semi-submarine offers a slower, more playful experience with a cabin below the waterline.
For families, the price also buys a simple activity with little preparation. You do not need swimming gear, masks, or special equipment. That makes it easier to add to a busy day.
Why families tend to enjoy it

The tour is well suited to children who like boats, water, and unusual vehicles. The red semi-submarine feels different from an ordinary sightseeing craft, and the change from open deck to underwater cabin gives the hour a clear sense of progression.
Child-size life jackets are available on request. The crew has also welcomed very young children, including children aged three and five, according to the experience information. You should still consider your child’s comfort with boat movement and enclosed spaces.
The chance to steer can be the highlight for a child. It is not a formal driving lesson, and it is not guaranteed, but a friendly skipper may let children or adults take the controls briefly. Small groups make this more likely because there is less competition for the captain’s attention.
Parents should set expectations about the underwater portion. Children may expect a constant parade of fish. Explain that the cabin offers a below-surface view, while marine life is a lucky extra. That way, the cliffs and villages remain part of the main event.
Comfort, safety, and practical limits

The tour includes life jackets, with child sizes available when requested. A licensed captain and crew operate the boat, and the skipper also provides the live English commentary.
You should wear comfortable clothes and shoes. Sunglasses, a sun hat, and a camera are sensible choices, especially for the deck sections. Chilled water is supplied, while alcoholic drinks are not included.
The boat has a tent for shade, but you should still prepare for sun exposure. The deck is the best place for wide views, which means many people will naturally spend time outside.
This experience is not suitable for wheelchair users or people with mobility impairments. Moving from the deck into the underwater cabin may require physical movement, and the supplied information does not indicate step-free access.
Large bags and luggage are not allowed. If you are coming directly from a cruise ship, plan where to leave bulky items before arriving at the meeting point.
Weather, water clarity, and boat traffic

The open-deck portion is fairly easy to enjoy in good conditions, but the underwater cabin depends heavily on the water. Clear water can reveal sea grass and small fish. Cloudy water can reduce the cabin view to shifting light and color.
Kotor Bay can also have considerable boat traffic, including large cruise ships. Besides changing the view, heavy traffic may affect water clarity. This is one reason I would avoid treating the tour as a wildlife-focused outing.
The scenery remains worthwhile even when the cabin view is modest. The mountains, stone settlements, and waterfront buildings are visible from above, and the guide can point out local sights along the route.
If you are choosing between this trip and a longer boat excursion, consider the weather and your schedule. The one-hour format limits your exposure to changing conditions and lets you keep other plans.
The experience for couples and solo visitors
Families are the clearest match, but you do not need children to enjoy the trip. Couples can treat it as a light, unusual way to see the bay, especially before dinner or after touring the Old Town.
Solo visitors may appreciate the easy format and central meeting point. You do not need to organize a private boat or commit to a half-day. The group setting also gives you a chance to hear local stories from the skipper.
The experience is at its best when you enjoy variety. You are switching between wide views and a smaller cabin, between sightseeing and watching the water below. It is less suitable if you prefer a quiet, serious historical tour or a long trip into the bay.
The English guide adds useful context, but this is still a relaxed outing rather than an in-depth cultural tour. You will hear points of interest and historic stories, yet the one-hour schedule leaves no room for lengthy stops.
Booking details that matter
You can cancel up to 24 hours before departure for a full refund, and the reserve-now, pay-later option keeps your plans flexible. Starting times vary, so you need to check availability for the date you want.
Skip-the-line access is included where available. Since the activity begins in a city park rather than at a distant marina, the main planning issue is getting there on time.
If you miss the departure, you may be able to join the next available time slot by arrangement with the operator. Do not rely on that as your main plan. Arriving 30 minutes early is the safer choice, particularly if you are driving or walking from a cruise terminal.
The provider is Montenegro Submarine & Speed Boat Tours. The experience is offered in English, with a licensed skipper serving as your guide.
Who should book this Kotor boat tour?
I would recommend it to families with children, first-time visitors who want a quick introduction to the bay, and anyone searching for an activity that feels different from a normal boat ride. It is also a sensible choice for cruise passengers because the meeting point is close to the port and the total time is only one hour.
I would be more cautious if you are booking specifically to see fish. The underwater cabin is the unusual feature, but conditions can produce only a few quick sightings or none at all.
At $35, the strongest value comes from combining three things: Kotor Bay scenery, a short guided cruise, and a playful below-surface cabin. Book it if you want a compact family outing and can treat marine life as a bonus. Skip it if you need a long, wildlife-heavy excursion or have mobility limitations that make cabin access difficult.
