Kotor: Bay of Kotor and Blue Cave Speedboat Tour

The Blue Cave is the star of this three-hour trip, but the ride there is half the fun. You skim past medieval Kotor, tiny bay villages, old palaces, churches, Mamula Island, and the narrow Verige passage before stopping for a swim in bright blue water.

I like the efficient route and the chance to cover a huge stretch of coast in one morning or afternoon. I also like the human touch from skippers such as Voign, Marco, and Andrea, who have been praised for good humor, safety, and help with mobility. The main catch is simple: a speedboat is exposed to wind, waves, and sun, and the Blue Cave can feel rushed when several boats arrive together.

Key points at a glance

• Blue Cave swim: Plan on about 20 minutes for swimming and snorkeling, though time inside the cave can shrink when boats crowd the entrance.
• Fast coastal route: The speedboat covers Kotor Bay, the outer gulf, Mamula Island, and the Luštica coast in three hours.
• Our Lady of the Rocks: You get about 20 minutes at the artificial island, with church and museum admission paid separately.
• Historic military stop: The former submarine tunnel is a quick photo stop cut into the Luštica shore.
• Good value at $53: Fuel, bottled water, rain coats, and snorkeling equipment are included.
• Come prepared: Bring a swimsuit, towel, sun hat, jacket, and extra water. Large bags are not allowed.

Why a speedboat is the right way to see Kotor Bay

Kotor Bay is too large to appreciate from one waterfront promenade. The shoreline folds through several small communities, and the best view is often from the water, with steep mountains rising behind tiled roofs and church towers.

A regular sightseeing boat can show you the bay, but it cannot cover this route as quickly. The speedboat gives you a broad sweep of the area in three hours, with enough time for a swim and two short cultural stops.

You meet at Park Slobode, a five-minute walk from Kotor Old Town and just behind the port. Look for the orange and blue company sign near the water. The skipper meets you there, and the boat leaves on a route that mixes scenery, swimming, and short visits rather than lingering at one place.

I like this balance for a first visit. You see the dramatic approach to Kotor, the inner bay villages, the open coast around Luštica, and the small islands near Perast without spending a full day on the water.

The tradeoff is comfort. The ride is exposed, and the boat moves quickly. On a calm summer day, that makes the trip lively. In cooler months or rougher weather, wind can cut through even a warm day. Several people found November and winter rides distinctly cold, while one spring trip was bumpy because of the weather.

Kotor Old Town from the water

The first views are of Kotor itself. From the boat, you see the old city walls climbing toward Saint John’s Hill. The fortifications stretch for about 4.5 kilometers, with sections reaching up to 15 meters thick and 20 meters high.

This is a useful angle because the walls are easy to underestimate when you are walking inside the old town. From the bay, their full scale becomes clear. You see how the city was protected by both mountain and water.

The guide points out the old town and the communities lining the bay. Commentary is in English or Serbo-Croatian. Guides have been praised for being funny, helpful, and easy to talk with, though the experience depends partly on where you sit. On a full boat, the skipper may need to repeat information for the front and rear sections, and some people found it hard to hear when the guide faced away.

I would sit where you can hear the skipper rather than choosing a seat only for its view. The boat itself provides plenty of scenery, so clear commentary is worth more than a perfect corner.

Muo, Prčanj, Stoliv, Dobrota, and Perast

The route passes a string of coastal settlements. On one side are Muo, Prčanj, and Stoliv. On the other are Dobrota and Perast.

These villages give Kotor Bay its lived-in character. You see a mix of homes, old stone buildings, churches, and former palaces pressed close to the water. The contrast is striking: calm sea-level settlements below steep mountain slopes.

Perast is passed rather than visited on foot. That matters if you want time in the town itself. You get views from the boat, but this tour does not give you a walking stop in Perast. The longer island visit comes later at Our Lady of the Rocks.

The route then reaches Verige, the narrowest part of the bay, only about 300 meters across. This passage separates the inner sections from the outer gulfs. Near it is the Church of Our Lady of Angels, another small landmark that helps you understand the shape of the bay.

I find this section more valuable than a simple photo cruise because the skipper connects the villages and waterways into one picture. You are not just looking at pretty houses. You are seeing how settlements developed along a narrow maritime route.

Mamula Island and the open Adriatic

After the inner bay, the boat heads toward the outer gulf and the Luštica Peninsula. You pass Mamula Island, a round island known for its coastal fortification. The stop is panoramic rather than a landing, so keep your camera ready and do not expect a walk ashore.

This part of the ride feels more open than the sheltered bay. The water can be choppier, and the speed becomes more noticeable. The boat passes through this stretch quickly, giving you a strong sense of the coast without using up the time needed for swimming and sightseeing.

This is also where weather matters most. On calm days, the open-water run is exhilarating. In wind or rain, it can be a cold, bumpy stretch. The operator supplies rain coats, but I would still bring a light jacket or hood, even in summer. Several people were glad to have extra layers on cooler departures.

Swimming at Montenegro’s Blue Cave

The Blue Cave is the tour’s main event. The cave covers about 300 square meters, with arches roughly 25 meters high and water around three to four meters deep. It has two entrances, and sunlight enters through the openings, reflecting off the water and walls.

That reflected light creates the blue glow. It is not an artificial effect or colored lighting. The brightness changes with the sun, the angle of the boat, and the conditions at the entrance.

The planned stop allows about 20 minutes for swimming and snorkeling. Snorkeling equipment is included, and this is the point where you can cool off after the fast ride. The cave is also shallow enough in places for a swim, but you should follow the skipper’s directions and use a life jacket if you need one.

Here is the important qualification: you may not spend the full swimming period inside the cave. When many boats arrive together, the entrance can become crowded. One person found the actual cave visit lasted only a few minutes because around ten boats were competing for space, although the alternate swimming area was excellent.

That is not necessarily a failure of the operator. The cave is small, popular, and shared with other boats. Still, set your expectations correctly. You are booking a Blue Cave visit with a swim, not a private cave session.

I would bring a waterproof phone pouch if you want photos, but do not let photography take over. The blue effect is easiest to appreciate from the water, and the boat may need to keep moving because of traffic inside.

The former submarine tunnel on Luštica

On the return leg, the boat pauses at a former submarine tunnel cut into the steep Luštica shoreline. Yugoslav forces built three such tunnels to hide and repair submarines and ships.

The tunnel shown on the route is up to 50 meters long and about 7 meters wide. Its average depth is around 8 meters, increasing to about 30 meters near the exit. You do not get a long exploration stop. Expect roughly five minutes for photographs and a close look from the boat.

This is a good contrast with the Blue Cave. The cave is shaped by light and water, while the submarine tunnel is a stark reminder of the coast’s military past. It gives the trip more substance than a string of scenic viewpoints.

If you like military sites, you may wish this stop were longer. If you mainly want swimming and scenery, five minutes is about right.

Our Lady of the Rocks and the Perast legend

The final major stop is Our Lady of the Rocks, an artificial island near Perast. The island was formed over centuries by adding stones and sinking old ships around a rock where two Perast fishermen reportedly found an icon of the Virgin Mary with Christ in 1452.

The tradition continues in the annual Fašinada procession, when local boats carry stones and place them around the island. That custom helps explain why this small island is not simply a scenic church stop. It is tied to the identity of Perast and its seafaring community.

You have about 20 minutes here for photographs, sightseeing, and a visit to the church and museum. Admission is not included, so bring money if you want to go inside. The tour information does not specify the entrance fee, so check locally before departure if the museum is important to you.

The timing is enough for a quick look, not a leisurely museum visit. Rain can shorten the stop, too. One trip returned early after bad weather interrupted the island visit.

I like placing this stop near the end. After the speed and open-water scenery, the island gives you a quieter cultural finish. If you want a longer look at Perast or the church, plan a separate visit on another day.

What the $53 price really covers

At $53 per person, this tour offers good value if you want several sights in one outing. The price includes fuel, bottled water, snorkeling equipment, and rain coats. You are paying for transport, the skipper, the route, and the swimming stop rather than for a formal museum-heavy tour.

The speedboat is particularly useful for cruise passengers or anyone with limited time in Kotor. You can see a large portion of the bay, reach the Blue Cave, and still return after three hours. A private or small-group option is also available if you want more control over the pace and seating.

Do not treat the included water as your entire supply for a sunny three-hour trip. One bottle may not be enough, especially during summer. Bring extra water if allowed, but leave large luggage and big bags behind because they are not permitted.

The score of 4.7 from 291 ratings, with 87 percent awarding the top mark, fits the strongest parts of the trip: fast transport, beautiful views, friendly skippers, and a lot packed into three hours. The lower marks center on understandable issues: rushed swimming, crowded cave access, uneven commentary, and cold or rough weather.

Who will enjoy this tour most

I would choose this for a first visit to Kotor when you want a broad introduction rather than a slow, specialized excursion. It suits couples, families, and small groups who want scenery, swimming, and a little local history in one package.

It also works well for people who do not want to spend a full day on a boat. Three hours is long enough to reach the outer coast but short enough to leave time for Kotor Old Town afterward.

Families should think about the boat ride and sea conditions. The experience is not suitable for pregnant women or people with back or heart problems. Rough water can make the ride uncomfortable, and the boat’s speed increases the effect of wind and spray.

The trip may also suit someone with limited mobility better than a walking-heavy day. One group received extra help for a father with mobility problems, but the activity still involves boarding a boat and visiting an island. Ask the operator about your specific needs before booking.

For the best comfort, I would choose a warm, calm day and bring:

• Swimsuit and towel
• Sun hat and sunscreen
• Light jacket or hood
• Extra drinking water
• Waterproof protection for your phone

Should you book the Kotor Blue Cave speedboat tour?

Book it if you want maximum scenery in minimum time. The route gives you Kotor’s walls, bay villages, Verige, Mamula Island, the Blue Cave, a submarine tunnel, and Our Lady of the Rocks for $53.

Do not book it expecting a private or unhurried visit inside the Blue Cave. The cave can be crowded, the swim may feel short, and the guide’s commentary may be difficult to hear from the back of a busy boat.

For most visitors with one free half-day, I think the value is strong. Pick a calm and warm departure, sit where you can hear the skipper, bring a jacket and extra water, and treat the Blue Cave as one part of a much larger coastal tour.
