Kotor’s water has a way of stealing your attention. This fast boat loop pairs postcard views with real stops like Our Lady of the Rocks and a swim in the Blue Cave, plus a look at a former submarine base that most people skip.

I especially liked the tight pacing for a 3-hour outing, and the way the route strings together Kotor Bay, Perast sightings, and the wartime stories you’ll miss on your own.

One thing to plan for: it’s weather-dependent. If seas are rough, you may lose the Blue Cave swimming portion or have the itinerary adjusted for safety.

Key things I’d plan for

  • Short swim window at Blue Cave: expect a quick, boat-off jump-and-go moment, not a long beach session.
  • Church rules at Our Lady of the Rocks: no swimwear inside; you need at least a T-shirt on, and drones are forbidden.
  • Wind and cold can hit fast on a speedboat: bring a jacket or layers even in shoulder seasons.
  • Submarine tunnels are brief but memorable: you’ll stop at the former clandestine base near the Verige strait.
  • It’s a small-group ride: max 25 travelers, which helps with viewing and boarding.
  • Know the 3€ extra cost: Our Lady of the Rocks admission is not included.

What makes this Kotor speedboat route worth your time

Kotor: Blue Cave Swim Stop, Lady of the Rocks & Submarine Base - What makes this Kotor speedboat route worth your time
This tour works because it’s built for people who want maximum scenery with minimal hassle. You don’t need to line up buses or figure out ferry schedules; you just show up near the Port of Kotor area, then let the boat do the heavy lifting.

You also get two different kinds of “wow.” The Blue Cave gives you that unreal blue color and a refreshing swim. The Our Lady of the Rocks visit adds culture and maritime storytelling that connects to the area’s seafaring life.

The icing is the submarine stop. Seeing the former military tunnels and hearing what they were used for gives the bay a different meaning than just pretty coastlines.

Price and value: why $39.91 can still feel fair

Kotor: Blue Cave Swim Stop, Lady of the Rocks & Submarine Base - Price and value: why $39.91 can still feel fair
At about $39.91 per person for roughly 3 hours, the value depends on what you would otherwise pay to see the same mix of places. You’re not just buying a boat ride—you’re paying for the route, the timing, and a guided experience that combines natural sights with history.

The tour includes the essentials that add up fast on your own trip: insurance, fuel, and water, plus an English-speaking skipper/guide. That matters on the bay, where “I’ll just figure it out later” can turn into waiting around.

The only clear add-on is the 3€ admission for Our Lady of the Rocks. If you’re okay with that small extra fee, the overall cost lines up well with a short, efficient afternoon on the water.

Getting to the meeting point near Port of Kotor (and avoiding the stress)

Your start point is Park Slobode 1, Kotor 85330, at Kotor Boat Tours & Blue Cave – Our Lady of the Rocks & SubmarinePark. It’s close to public transportation, but it’s also a busy port area, and traffic can be rough around the park due to roadworks.

Here’s the practical tip: don’t treat the directions like a suggestion. Aim to be there at least 30 minutes early. One common frustration is simply locating the exact vendor stall.

If you’re driving, give yourself extra time. Heavy traffic around the park and roadworks on the main road can eat your buffer quickly, and you don’t want to arrive flustered when the boat is ready.

Stop 1: the Bay of Kotor cruise that sets the tone

Kotor: Blue Cave Swim Stop, Lady of the Rocks & Submarine Base - Stop 1: the Bay of Kotor cruise that sets the tone
Your tour starts with a scenic boat cruise through the Bay of Kotor. This is your orientation moment—historic fishing villages, Mediterranean greenery, and the dramatic shoreline views.

The stop is short (about 20 minutes) and the admission there is free because it’s part of the boat route. Think of it as your “get your bearings fast” segment. The value is that you’re seeing the bay from the water while your eyes adjust to the scale of the cliffs and coast.

If you’re short on time in Kotor, this part alone helps you understand why people fall for the bay’s shape. Even if you don’t care about photos, it helps the rest of the tour click.

Stop 2: Our Lady of the Rocks (Gospa od Skrpjela) and what to look for

Kotor: Blue Cave Swim Stop, Lady of the Rocks & Submarine Base - Stop 2: Our Lady of the Rocks (Gospa od Skrpjela) and what to look for
Next you’ll reach Our Lady of the Rocks (Gospa od Skrpjela), a manmade island shaped by generations of seafarers. The church visit is about 20 minutes, and the 3€ admission is not included.

Here’s what makes this stop more than a quick photo spot:

  • The church is tied to the island’s creation and local maritime traditions.
  • There’s a small museum and paintings you can walk through.
  • You’ll often see artworks, votives, and handcrafted items, which helps explain the island’s role in everyday devotion and seafaring life.

Practical rules you must follow:

  • It’s forbidden to swim at Our Lady of the Rocks.
  • No drone is allowed.
  • You can’t go in the church in swimwear; you need at least a T-shirt on.

Also, plan your timing with opening hours in mind. In spring and autumn, the church and museum close earlier. If you’re visiting in April/May/October, you’ll want to be ready for the earlier cutoff. Dress for chillier weather too—on the water it can turn cool fast, and the island isn’t a warm-up zone.

Passing Perast from the water: the part you notice later

Kotor: Blue Cave Swim Stop, Lady of the Rocks & Submarine Base - Passing Perast from the water: the part you notice later
You’ll pass by Perast, a town that grew during Venetian times as a maritime hub. From the boat, you get glimpses of the baroque palaces, old churches, and narrow stone streets.

You won’t have a landing here, so don’t expect a stroll. But it’s a useful reminder of where the “look” of the bay comes from: the coast isn’t just scenery; it’s layered with centuries of seafaring wealth and craft.

If you’re the type who later wants to add Perast on another day, this pass helps you decide what kind of exploring you might want next.

Mamula Island: fortress island stories from the boat

Cruising forward, your guide will point out Mamula Island, a small fortress island with a heavy past. It was built in the 19th century as a military fort and later used as a prison during World War II.

Even though you’re only seeing it from the water, this stop changes the mood. It’s not just pretty cliffs anymore; it’s a reminder that the bay’s strategic location mattered in both world wars.

If you like history that connects to geography, this is one of the easiest segments to enjoy—because you can literally see the reasons for its military relevance.

Stop 3: Blue Cave swim stop (Plava Spilja) and how to make it fun

Then comes the main event: the Blue Cave (Plava Spilja). The tour name sells it for a reason—sunlight hitting the white-pebble bottom creates that striking blue glow. You’ll spend about 20 minutes here, and swimming is typically part of the experience.

A few practical realities you should plan for:

  • The swim is boat-based, not beach-based. You’re likely stepping off and getting back on with crew help.
  • The ladder can be tricky. One helpful tip from past riders is that the steps can be narrow, so water shoes can make it safer and more comfortable.
  • Bring a towel. It’s also smart to have flip-flops ready since the deck can get slick.

And timing matters. After 6 pm, the Blue Cave water color isn’t the same as during daylight, so if you have flexibility, aim earlier.

Weather can also change everything. If seas are choppy, you might still see the cave but not get the same full swimming portion. In certain situations, the itinerary may be adjusted and the Blue Cave visit skipped. That isn’t a surprise on a speedboat; it’s part of operating on an open-water coast.

Former submarine base and the Verige strait (Bay of Tivat)

Your final major history stop is the former submarine tunnels near the narrow Verige point, reaching into the Bay of Tivat. This segment is brief—about 5 minutes—but it hits a very specific kind of Montenegro story: Cold War-era secrecy.

This is one of those moments where the bay’s quiet surface hides a lot. The tunnels were once top-secret military infrastructure, and now visitors can see what that world looked like.

The short time is a tradeoff: you won’t linger, but you also won’t lose the overall flow of the tour. For most people, it lands as a strong final chapter before heading back to the meeting point.

What the crew and timing feel like in real life

This is a speedboat, so the experience is more “active sightseeing” than “sit back and coast.” It moves fast between stops, and that keeps the afternoon from dragging.

One thing to appreciate is organization. The tour runs with an eye toward schedule, with crew members assisting passengers on and off the boat. On some departures, there’s even mention of jackets being provided if the wind picks up, which is good to know if you tend to get cold easily.

You might also get commentary that feels more like a storyteller than a textbook. Names like George and Aki have come up in skipper/crew feedback, and the common theme is friendly, safety-conscious guiding.

Still, don’t plan on constant live narration. Depending on the moment, you might hear audio-style information as well. Bring your curiosity and ask questions when you can—those short moments with the crew are where you’ll usually get the most meaning.

What to bring so the boat doesn’t run your day

You’ll have a better time if you pack like this is a mix of sightseeing and quick-water fun.

Bring:

  • Sunglasses, sunscreen, and a sun hat
  • Swimwear (if you want to swim at Blue Cave) plus a towel
  • Comfortable shoes or sandals, ideally with something you can step into on deck
  • Flip-flops for easier movement
  • A jacket or layers, especially in spring, autumn, and any breezy month

If you’re visiting in shoulder seasons, the wind while the boat moves can feel colder than you expect. One easy fix is wearing layers instead of relying on the sun to warm you.

Food and drinks aren’t included, unless something is specified on your departure. So if you get peckish, plan ahead. The tour water is included, but you don’t want to count on snacks being available.

Who this tour suits best (and who should think twice)

This is a strong fit if you:

  • Want a 3-hour highlights loop and don’t want to spend the whole day planning
  • Like scenic boat rides and short, focused stops
  • Are comfortable with quick boarding and a brief swim option

It may be less ideal if you:

  • Don’t handle boat decks well or feel unsteady stepping on and off
  • Expect long beach time at Blue Cave (this is a short stop)
  • Are visiting during uncertain weather windows and really need Blue Cave swimming no matter what

The upside is the small group size (max 25), which helps with viewing and getting on/off without chaos.

Should you book this Kotor Bay speedboat tour?

I think you should book it if you want an efficient afternoon that mixes Blue Cave with Our Lady of the Rocks and adds real wartime context through the submarine tunnels. It’s good value for a short window in Kotor, especially because the route handles the logistics for you.

Book it with eyes open if you care deeply about the swim timing. Weather can reduce or change the water portion, and the Blue Cave color is best in daylight. If you can travel earlier in the day and you pack layers and swim-ready gear, you’ll set yourself up for the best possible version of the tour.

If you want, tell me your travel month and your comfort level with getting in and out of boats, and I’ll suggest the best time window and what to prioritize.
