Kotor: Boat Cruise with Blue Cave Swim and Submarine Base

The best part of this Kotor Bay speedboat tour is its range. In three hours, you move from a 15th-century island church to abandoned military tunnels, a World War II prison fortress, and clear water for swimming. The fast boat makes distant sights practical without giving up the pleasure of being out on the bay.

I like the mix of history and swimming, and I like that captains such as Marko, Peter, Andre, and Marco add useful local stories rather than simply driving from stop to stop. The main consideration is the Blue Cave stop: in busy conditions, you may swim near the cave rather than inside it, and the open boat can feel chilly outside the hottest summer months.

Quick points to know

• Three hours, four very different stops: You see Our Lady of the Rocks, Mamula Island, the Blue Cave area, and former submarine tunnels in one compact outing.
• The speedboat saves time: Fast runs between stops let you cover much more of the bay than a slow harbor cruise.
• Swimming is usually near the Blue Cave: Clear water and snorkeling are the focus, but boat traffic can limit time inside the cave itself.
• History gives the trip weight: You hear about Yugoslav military tunnels and Mamula’s use as an Italian concentration camp during World War II.
• The boat setup is practical: Water, a refrigerator, music, Wi-Fi, shade, snorkeling masks, and life-saving equipment are provided.
• The value is strong at $56: For a half day of transport, sightseeing, commentary, and swimming, this is a useful choice for a first visit to Kotor Bay.

Why this three-hour boat trip works so well

Kotor Bay is full of places that look close on a map but take time to reach by road. The speedboat solves that problem. You leave from Kotor, skim past Perast and Tivat, and continue toward the outer bay and the Adriatic coast without spending the day in traffic.

The trip is active but not exhausting. You sit in the open air, watch the shoreline slide by, and get short stops for photographs, history, and swimming. I see it as a sampler rather than a slow, intimate visit to each place. You will not have hours at any one attraction, but you will get a broad look at the bay and its nearby coast.

The boat can hold up to 22 people, though some departures are much smaller. One October outing had only eight people, and other accounts describe groups of six. Smaller groups make it easier to hear the captain, move around for photographs, and get help when climbing back aboard after swimming.

The boat is described as clean, new, comfortable, and partly shaded. There is a refrigerator, bottled water, onboard Wi-Fi, and music. Those details matter on a fast boat, especially in summer when the sun is strong. The ride can still be windy and cool, so bring a light coat outside July and August.

Leaving Kotor and racing along the bay

Meet at the MontenegroGlobe agency near shopping center Kamelija, a few minutes from Kotor’s old town and the port. This is a handy starting point if you are staying inside the old town, but parking in Kotor is notoriously difficult, so arriving by car takes extra planning.

Once aboard, the first run lasts about 20 minutes. This is when you get the pleasure of speed. The boat is quick enough to make the open-water sections feel exciting, but the captain and crew keep safety equipment on board and pay attention to conditions.

The views begin before the first official stop. You pass small coastal settlements and get changing views toward Perast, Tivat, Porto Montenegro, and Herceg Novi. I like this part because it gives you a sense of how scattered the bay’s communities are. The shoreline is not just a backdrop. It is the reason a boat trip makes sense here.

Music plays during some departures, and captains have been praised for adding jokes and conversation along the way. The tone depends on the captain, but the strongest reports describe a relaxed trip with clear historical explanations and friendly help in the water.

Our Lady of the Rocks and Perast in 20 minutes

The first main stop is Our Lady of the Rocks, the artificial island opposite Perast. Local fishermen began building it in the 15th century, creating the island by placing stones and sinking old ships in the water. It is one of the most distinctive sights in the bay because the island is human-made rather than a natural outcrop.

You have about 20 minutes here for photographs and a visit. The church is open to those who pay the additional €2 entry fee. Inside are 68 paintings by Tripo Kokolja, a 17th-century Baroque artist from Perast.

That fee is modest, but the short stop means you should decide before arrival if you want to go inside. If you prefer photographs and the view across to Perast, the island itself is enough for a quick visit. If you care about religious art and local culture, pay the fee and use your limited time indoors.

The island is also a good place to understand the scale of the bay. From the boat and shore, you see Perast’s old waterfront and the mountains rising behind it. Keep your camera ready, but do not expect a long, quiet church visit. This is a timed boat excursion, not a full walking tour of Perast.

Mamula Island and a difficult wartime past

After about 30 minutes on the boat, you reach Mamula Island for a short photo stop of roughly 10 minutes. The island’s fortress is round, stone-built, and imposing. Its setting looks peaceful from the water, which makes the wartime story more unsettling.

Mamula was converted into a concentration camp by the Italians during World War II. The local captain explains this history while you look at the fortress from the boat. That short account adds an important layer to what might otherwise seem like a photogenic island fortress.

You should set your expectations correctly. The listed stop is a photo stop, not a land visit through the fortress. The value is in seeing the structure, learning what happened there, and placing it within the military history of the bay. The quick visit also keeps the overall route moving.

This is one of the places where a good captain makes a real difference. Marko, Peter, Andre, Marco, and other guides have been singled out for giving context at the stops. Ask questions if you want more detail, but remember that the route has several destinations to cover.

Swimming at the Blue Cave and nearby coves

The next run takes about 10 minutes to the Blue Cave area. The advertised swimming and snorkeling time is about 25 minutes, and this is usually the most anticipated part of the trip.

The cave gets its blue color from sunlight entering through the water and reflecting off the rock. From the boat, the effect can be striking, especially when the sea is calm and the light is strong. You receive a snorkeling mask, and the clear water can reveal fish and underwater rock formations around the cave area.

Here is the practical point that matters most: swimming conditions vary. Some departures enter the cave for photographs, then continue to a quieter cove for the actual swim. In busy periods, other boats can crowd the cave, making it hard to swim inside safely or comfortably. One account specifically noted that the swim was outside and a little farther from the cave, while another described the nearby water as clearer and better for seeing fish.

So book this for a Blue Cave visit plus a clear-water swim, not on the promise that you will always swim inside the cave. Captains may change the order of the cave and swimming stop to avoid crowds. That flexibility can improve the experience, but weather and boat traffic remain outside anyone’s control.

Non-swimmers are not left out. Life-saving equipment is included, and one captain provided life jackets and helped nervous swimmers get back onto the boat. Still, you should bring swimwear and a towel, and tell the crew if you are uneasy in the water.

The water stop is also where the open boat feels best. You can cool off, use the mask to look below the surface, and enjoy a break from the engine noise. On hot days, the shade and sea spray make the ride more comfortable than you might expect. On cooler days, bring a coat for the return journey.

Former submarine tunnels built by Yugoslavia

After the swimming stop, the boat heads back toward the bay and pauses at former submarine tunnels. The ride takes about 15 minutes, followed by a very brief five-minute photo stop.

These openings were built by the Yugoslav Army and cut into the shoreline for military use. They are stark compared with the ornate church at Our Lady of the Rocks and the fortress at Mamula. That contrast is part of the appeal: the route shows you both the ceremonial and military sides of the coast.

Again, this is an exterior look rather than a long exploration on foot. You will see the tunnel entrances from the water and hear about their purpose. Five minutes is enough for photographs and a short explanation, but not enough for a detailed military tour.

I appreciate the inclusion of this stop because it keeps the trip from becoming only a scenic cruise. The bay’s beauty is real, but the shoreline also carries layers of religious, naval, and wartime history. The submarine tunnels make that clear.

The return trip through Kotor Bay

The final run lasts about 30 minutes and returns you to MontenegroGlobe near Kamelija. This is a good time to take in the towns you may have noticed earlier: Perast, Tivat, Porto Montenegro, and Herceg Novi.

The boat’s speed means the return does not feel like wasted time. You are still moving through the scenery rather than retracing the day by road. On clear days, this may be your best chance to take wider photographs of the bay and the coastal towns.

The trip generally starts on time, though weather can change the plan. A storm once caused a captain to extend the outing so the group could shelter at a beach, with raincoats provided afterward. That kind of adjustment is useful, but it also explains why the operator reserves the right to cancel in poor weather or if too few people book.

What $56 buys you

At $56 per person, this is good value if you want several major sights in a short period. The price includes boat transport, a bottle of water, a snorkeling mask, and life-saving equipment. You also get an English-speaking guide, scenic transport between distant stops, and time for swimming.

The strongest value comes from combining activities that would otherwise require separate planning. You see a historic artificial island, a wartime fortress, military tunnels, and a famous cave in one three-hour route. You also avoid arranging taxis, local boats, and separate entrance points.

There are limits. Food and extra drinks are not included, and the €2 church entry fee is separate. The church visit is optional, so this adds little to the overall cost. The short schedule also means you should not book this expecting long visits in Perast, Mamula, or the submarine tunnels.

The transport receives especially strong marks, with 90 percent of ratings giving it a perfect score and an overall rating of 4.8 from 1,155 ratings. The recurring strengths are comfortable boats, easy check-in, attentive captains, and well-timed swimming stops. One poor account described an uncomfortable exchange at the office before departure, so the welcome at the agency may not match the quality of the boat crew. That concern is worth noting, even though it appears to be an isolated complaint among otherwise very positive feedback.

Which departure time and season make sense

Summer is the easiest season for swimming. Morning departures help you avoid the worst heat, and several people have found the cooler part of the day pleasant. Midday can offer strong light for the cave’s blue effect, but the sun and glare are more intense.

In October, the water may still look inviting, but the open boat can feel cold. One useful tip is to choose the noon departure in October and bring a coat. Sunglasses are useful in every season because speed, water, and bright rock create plenty of glare.

The cave can be busy in high season. A captain may reverse the order of the swimming stop and the cave to find quieter water. This is one reason I would avoid judging the trip solely by whether you swim inside the cave. The better measure is whether you get a good view, safe water, and enough time to enjoy the stop.

Who should book this speedboat tour

I would choose this trip if you have only a short stay in Kotor and want a broad introduction to the bay. It also suits couples, solo visitors, and small groups who like a mix of fast transport, photographs, history, and a swim.

Solo visitors can meet other people easily on a shared boat. Smaller groups make the trip more personal, while a fuller boat may have a livelier atmosphere. The shaded seating and refrigerator help on hot days, and the captain can usually provide practical assistance around the swim.

You should think twice if you want a slow, quiet cruise or a long museum-style visit. The speedboat is noisy while moving, the stops are brief, and the Blue Cave may be crowded. The trip is also not suitable for wheelchair users or people over 95, and pets and bikes are not allowed.

Bring sunglasses, swimwear, a towel, and a camera. I would also add a light jacket, even in summer, since the ride can be cool once the boat picks up speed. Parking is difficult in Kotor, so walking from the old town or port is simpler when possible.

Should you book the Kotor Blue Cave cruise?

Book it if you want the most variety from a three-hour outing. At $56, the combination of speedboat transport, four contrasting stops, an English-speaking captain, snorkeling equipment, and a swim offers solid value.

Go with realistic expectations. You may photograph the Blue Cave but swim in a nearby cove, and Mamula and the submarine tunnels are viewed from the boat. If those limits suit you, this is an efficient and enjoyable way to see more of Kotor Bay without giving up time in Kotor’s old town.
