Blue water first, then submarine history. This Kotor speedboat trip packs the Blue Cave and the former submarine tunnel into one short, action-heavy outing. I love that it’s priced like a deal for a full circuit around the bay, and I also like the mix of natural sights and human-made landmarks. The big heads-up: the Blue Cave can be off-limits depending on sea conditions.

You also get a real taste of Perast. The stop for Our Lady of the Rocks (and the cruise-by around Perast’s old waterfront) hits that classic baroque coast vibe without turning the day into a long museum crawl. One drawback to plan around is that the day’s flow can change if the sea is rough, which may limit time in the cave or even eliminate the cave swim.

Quick hits

• Blue Cave timing can be short when boats are lined up, and swimming may shift to a nearby spot.
• Our Lady of the Rocks gives you the story behind the postcard view from Perast.
• Submarine tunnels from the inside are the most unusual stop on the route.
• Mamula Fortress is a fast but memorable pass by a former prison island.
• Short 3-hour format makes it easier to fit into a cruise day or a tight itinerary.

The 3-hour Kotor Bay route: fast, scenic, and schedule-tight

This is an about-3-hours speedboat experience with travel time included, so you’re not just standing around at the pier. You start at Hawaii Boat Tours Kotor at Park Slobode 1 in Kotor, and the trip ends back at the same meeting point. It’s offered in English, and you’ll get a mobile ticket after confirmation.

The pace is the point. You’ll be in motion across Kotor Bay, then make brief stops that are long enough to look, take photos, and (if conditions allow) get in the water. The whole experience runs as a small-group style tour, and the wider tour limit is up to 80 travelers, so on busy days you can feel the crowds even if the boat ride itself is more manageable than a big bus.

Stop 1: Blue Cave swims, snorkeling, and the weather reality

The Blue Cave is the headline for a reason. It’s famous for its surreal blue water, and when access is possible you get a chance to swim and snorkel in a spot that looks like it was made for photos. On paper, the cave stop is set for about 30 minutes, and the admission ticket is free.

Here’s the practical reality to plan for: cave access depends on conditions at the entrance. When winds or waves make entry unsafe, you may not go into the cave at all. Even on days when they can reach the cave, you might find a queue of boats, which can reduce the time you actually spend inside.

What I’d do if you book this as your Blue Cave day: treat snorkeling as a bonus, not a guarantee. If your trip dates line up with a forecasted rough day, adjust expectations. You can still get a swim later in a nearby spot outside the cave, and that can still be very good water, just with a different view.

Stop 2: Our Lady of the Rocks and the Perast cruise-by effect

Next comes Our Lady of the Rocks, the iconic man-made island in the Perast area. You’ll have about 20 minutes here, which is enough time to take in the church and the setting without feeling rushed off the island. Admission is listed as free, so you’re really paying for the boat ride and the route, not entry fees.

After that, the tour route includes cruising to the small town of Perast. Even without long walking time, you get that sense of place: baroque architecture, historic palazzos, Catholic churches, and defensive towers around the bay. The old town of Perast is a UNESCO World Heritage site, and the charm of having just one main street means you can understand the layout quickly.

This stop is valuable even if you’re not a big church person. It explains why this coast looks the way it does and why local legends stick around. And if you’re the type who loves boat views more than museum views, this is a strong fit because Perast reads best from the water.

Stop 3: Former submarine tunnel from inside the speedboat experience

This is one of the most unique moments on the itinerary. You’ll explore the former submarine tunnels, learning their story as the boat travels near and into the mountain area. The time is short, about 10 minutes, but the payoff is that you see the structure from the water and get the wow-factor without turning it into a full day.

Why this stop works: it’s not just sightseeing. It’s a look at military engineering in a dramatic setting. Even when narration is light, the tunnels themselves create instant visual interest because they look like something you’d expect in a film set, not along a working coastline.

If you care about hands-on, visual history, this is often the part that people remember most after the Blue Cave. It’s also the easiest stop to enjoy when weather is mixed, since it doesn’t require the same kind of water-entry risk as the cave.

Stop 4: Mamula Fortress pass-by on the prison-island island line

The last classic coastline stop is Mamula Fortress, with about 10 minutes around the island. This is a quick look, not a long visit, but it has a strong story: Mamula was once used as a prison island. The skipper will share the history as you go by, so you’re not stuck just looking at a rock in the sea.

The pass-by format matters. You’re getting the island silhouette and fort shape without losing time you’d need for swimming earlier. It also helps keep the whole tour inside that ~3-hour window.

What the speedboat ride is really like: bumpy, loud, and lively

Expect a real speedboat experience: the ride can be bouncy, especially when you’re outside the calmer pocket of the bay. Choppy water is a common theme when there are lots of boats moving in both directions, and that can make the trip feel longer than the time on the clock.

Comfort tips that actually help:

• Wear shoes you can keep secure on deck, not sandals that slide.
• Bring something for sun and spray, because you may get wet.
• If you’re sensitive to rough rides, consider timing this earlier in the day when conditions can be steadier.

Onboard comfort and crowding come up in feedback. Some people report numbers in the low-to-mid teens on the boat. The tour operator states the boat has a licensed capacity including the captain (and also mentions private boat tours exist if you want more space). So if you want elbow room, the shared-boat style can feel tight.

Also note: water service is not consistently included. Some people explicitly wished they’d had water onboard. If hydration is a priority for you, plan to bring your own unless you’re told otherwise at check-in.

Price and value: why $32.53 can feel like a bargain

At $32.53 per person for about 3 hours, you’re paying for transportation plus access to the core sites, with admission tickets listed as free for the stops shown. That’s part of the value: you’re not paying separate entry fees for the big-name spots on this route.

What makes it feel like a deal is the number of different experiences packed into one trip:

• a famous coastal water cave (when conditions allow)
• a legend-linked island church
• submarine-tunnel engineering
• a fortress-prison island pass

When the day goes well, you get the full “wow chain” that’s hard to assemble on your own without renting a boat or piecing together multiple operators.

When the day doesn’t go well, the price can feel less impressive because the highlight (Blue Cave entry and inside swimming) might be limited or skipped. That’s not unique to this tour, but it’s worth knowing before you commit.

Group size expectations: small enough for fun, crowded enough to matter

Even though it’s not a giant tour bus, this is not a private boat day. The overall tour can have a maximum of 80 travelers, and the boat itself can be full on peak departures.

What you might notice if it’s busy:

• more people clustered for photos
• less ability to spread out
• waits at popular stops like the cave entrance area
• swimming spots that feel like a busy intersection

One practical takeaway: if you’re the kind of person who wants quiet snorkeling and lots of space, this shared tour may feel hectic. If you want energy, speed, and a “do the highlights fast” itinerary, it can be a great match.

Captains, safety, and communication: what to watch for at departure

Safety is usually described as a strong point when the captain is experienced and the boat handles other traffic well. Some accounts praise skippers for navigating around the heavy boat presence in Kotor Bay, and for keeping things organized while you’re moving between stops.

Communication quality varies. Some people wanted more history or site context, while others felt the skipper did a good job explaining what you’re seeing. A few people also noticed that parts of the narration sounded recorded rather than delivered in live detail.

At the dock, make sure you get clear answers quickly:

• where you’re getting off for each stop
• what’s changing if the Blue Cave can’t be entered
• how swimming will work that day

If you’re arriving late, the tour depends on departing on schedule. Late arrivals can lead to missed boarding, especially for cruise ship passengers dealing with tender delays. If that’s your situation, build extra cushion into how early you leave the ship.

Who this tour suits best (and who should skip it)

This tour is a strong fit if you want:

• a fast-paced way to see multiple Kotor Bay landmarks in a few hours
• the chance to swim in blue water (even if it’s not always inside the cave)
• the submarine tunnel stop, which is a standout versus most simple cave-only trips
• a shared tour that still feels like an adventure, not a slow sightseeing day

You may want to consider a different option if:

• you get easily seasick or hate bumpy rides
• you need lots of space and quiet for snorkeling
• Blue Cave entry is the only thing that would make the day successful for you
• you’re traveling on a tight cruise schedule where a delay could cause missed boarding

Should you book this Kotor Blue Cave speedboat tour?

If you’re booking for the full package, I think it’s worth considering. The combination of Blue Cave (when accessible), Our Lady of the Rocks, submarine tunnels, and Mamula Fortress is exactly the kind of itinerary that’s hard to replicate cheaply on your own. The rating is very high, and the most praised parts tend to be the scenery, the tunnel visit, and the feeling of safety while the captain handles the busy waterways.

But if your trip window is forecasted rough, treat Blue Cave entry as uncertain. If it’s your main mission, plan your mindset for a Plan B swim outside the cave or a different stop flow.

My rule of thumb: book it if you want action and variety, and you’re flexible about sea conditions. If you’re not into bumpy speedboat rides or you need guaranteed cave entry, consider choosing a more weather-proof plan or a private option for space.
