Kotor: Blue Cave & Our Lady of The Rocks & Submarine Base

The best views here come from the water. This Kotor speedboat trip combines Blue Cave swimming with old churches, wartime tunnels, and wide Bay of Kotor views. I like the mix of action and history, especially the chance to visit Our Lady of the Rocks and see Mamula Island from the sea. I also like that fuel, insurance, snorkeling gear, and a local English-speaking skipper are included. The main drawback is simple: rough seas can change the route, and the ride may feel brisk for anyone who prefers a slow boat.

You will spend much of the day moving between stops, with music playing and a modern speedboat covering long stretches quickly. Captains Boban and Aljosa receive especially warm praise for safe driving, good music, and clear explanations. The Blue Cave is the star, but the submarine tunnels and Perast views give the trip more substance than a simple swim outing.

Key points to know before booking

• The Blue Cave gets about 30 minutes: Bring swimwear, a towel, and a charged phone for the brightest part of the trip.
• Our Lady of the Rocks is a real stop: You get about 20 minutes on the island, while church and museum entry costs €2 if you choose to go inside.
• The route covers several historic sights: You pass Perast, enter a former submarine tunnel, and see Mamula Island, once a WWII prison.
• The speedboat saves time: The boat handles long stretches across the bay and out toward the open sea far faster than a traditional boat.
• Weather matters: In rough conditions, the route may change for safety, and the Blue Cave may not be possible.
• The price is strong for a full outing: At $53 per person, the tour includes fuel, safety equipment, snorkeling masks when available, fees, and a licensed skipper.

Why this boat trip works so well from Kotor

Kotor is easy to admire from its stone lanes and waterfront, but the bay makes more sense when you see it from a boat. Steep mountains rise around the water, while small islands, old villages, forts, and marinas appear in quick succession.

This tour gives you a broad look at the area in one outing. It is not only a swim stop. You also get church art, naval history, a former prison fortress, a luxury marina, and a final view of Perast.

The experience begins at one of two Hawaii Boat Tours Kotor meeting points. The exact point depends on the option you book, so check your confirmation carefully. Arrive 30 minutes early. Summer traffic can be slow, and late arrivals may not be accepted or refunded.

The listed duration can range from 1.5 to 9 hours depending on the option and schedule. The route described here includes several speedboat legs and is best treated as a substantial half-day outing, with longer versions possible. Ask for the exact length when you book.

Leaving Kotor by modern speedboat

The boat is one of the practical strengths of the experience. It is described as a new, modern speedboat, with fuel included. That matters because this route covers a lot of water, including the outer bay and the Blue Cave area.

A speedboat gives you more time at the stops than a slow craft would. It also creates a livelier ride, with music and open views as you move between locations. The trade-off is that the ride can be windy and bumpy, especially when the sea is not calm.

Life jackets are provided, and the boat carries a first aid kit. The captain is also your guide, so you get commentary without adding a separate guide to the group. Boban is praised for handling rainy conditions calmly, while Aljosa is described as friendly and professional. Music is part of the mood, and several people singled out the song choices as a highlight.

I would keep your phone in a secure, water-resistant place. You can request photos from the captain, but do not count on having every moment photographed. The safest plan is to enjoy the ride first and ask about photos once you are settled.

Perast and Our Lady of the Rocks in 20 minutes

The boat passes Perast early in the route. This small waterfront town is known for baroque buildings, old stone houses, and its position beneath the mountains. From the water, you get a clean view of the town without spending time in traffic or searching for parking.

The actual island stop is Our Lady of the Rocks, a small artificial island with its famous church. You get around 20 minutes here, enough for a short walk, a look at the church exterior, and views back toward Perast and the bay.

Church and museum entry is optional and costs €2. That modest fee is not included, so carry a little cash or confirm accepted payment methods before setting off. If you want a serious look at the interior and museum, 20 minutes may feel short. If you mainly want the island, the views, and a quick sense of the place, the stop works well.

This is one of the calmer parts of the day. After the speed and noise of the boat, a short walk on the island gives you time to stretch your legs. The stop is brief, so do not wander far from the meeting point.

Inside the former submarine tunnel

The boat then reaches a former submarine tunnel cut into the cliffs. The visit lasts about 5 to 10 minutes, depending on the schedule shown for your booking.

This is not a polished museum. Its value comes from the setting. The dark opening in the rock, the narrow entrance, and the wartime purpose make the stop feel more atmospheric than formal. Your skipper explains the tunnel and brings some of its past to life.

Keep your expectations in the right place. You are not getting a long guided tour with displays and exhibits. You are seeing a surviving military structure from the boat and briefly entering or visiting the tunnel area.

That short stop works because it breaks up the sightseeing pattern. The day is not just churches and swimming pools. You also get a glimpse of the bay’s military role during the 20th century.

Mamula Island and its prison fortress

Mamula Island appears as a fortress rising from the sea. It was once a WWII prison, and the fort’s isolated position gives it a stark feel. The tour includes a photo stop, guided commentary, and a pass by lasting about five minutes.

You should think of this as an exterior view rather than a full island visit. The boat provides a strong angle for photos, and the captain explains the island’s past, but the schedule does not promise a long walk ashore.

The history can feel heavy. The fortress is attractive from a distance, yet its purpose was grim. That contrast is part of what makes the stop memorable. Your skipper’s explanation helps turn a quick pass by into something more meaningful.

If you want to explore every historic site at length, this tour may feel too fast. If you prefer seeing several important places in one day, the short stop is a good compromise.

The Blue Cave swimming stop

The Blue Cave is the main event. The boat reaches the cave area after the Mamula stop, and you get about 30 minutes for swimming and snorkeling.

Light reflecting through the water gives the cave area its blue-green color. Conditions vary with the weather and sea, but the clear water is the reason this tour attracts so much attention. You can swim, use the provided snorkeling masks when available, or simply stay aboard and enjoy the view.

The tour also mentions cliff jumping. Treat that as an optional activity, not a requirement. You should judge the conditions for yourself and follow the captain’s safety advice.

Thirty minutes is enough for a refreshing swim, but it is not a full beach day. Put your swimwear on before departure, bring a towel, and keep your phone protected. You will not want to waste half the stop changing clothes or searching for dry storage.

Weather can change this part of the route. In rough sea conditions, the captain may take you somewhere else for safety. One recent outing could not reach the Blue Cave because of weather, although the rest of the trip still went ahead successfully. That is an important point when you book: the cave is the highlight, but it cannot be guaranteed in every season or on every day.

The long ride back across the bay

After the swim, the boat takes roughly an hour to return. This is a chance to settle in and take in the views, but it is also the longest uninterrupted ride of the day.

You may appreciate the speed because it gets you back to Kotor without a slow crawl. On the other hand, anyone prone to motion sickness should prepare carefully. The boat moves quickly, and open-water conditions can be rougher than those inside the sheltered bay.

The route includes views of Porto Novi Marina, a luxury seaside resort filled with yachts and modern waterfront buildings. It offers a sharp contrast with Perast’s old stone architecture and the wartime tunnels. The changing scenery is one of the trip’s strengths: you see historic towns, military sites, resort development, and open sea in one sweep.

Music continues to shape the ride. Several guests specifically praised Boban’s song choices, and one person called the music a 10 out of 10 part of the day. If you prefer a quiet, lecture-heavy cruise, this may not be your ideal style. If you like a relaxed boat atmosphere, it adds energy without requiring constant commentary.

What $53 includes, and what it does not

At $53 per person, the tour offers good value if you want several sights and a swim without arranging separate transport. The cost includes the speedboat, fuel, insurance, taxes, life jackets, snorkeling equipment when available, and a licensed English-speaking skipper.

You also get the boat transfers between Kotor, Perast, the tunnel, Mamula Island, and the Blue Cave area. That matters in the Bay of Kotor, where separate taxis, boat hires, and entrance costs can quickly add up.

The only stated extra is the €2 optional entrance to the Our Lady of the Rocks church and museum. You are paying mainly for transport, access to a packed route, local guiding, and the Blue Cave stop rather than for a long museum program.

Private and small-group options are available. The exact group size is not stated, so check the option before booking if personal space matters to you. A private boat should suit families or couples who want more control over the pace, while a small group usually keeps the cost down.

The tour has a 4.9 rating from 936 reviews, which suggests very strong overall satisfaction. The praise centers on the captains, boat quality, safety, music, and the range of locations. The main caution comes from weather, not from the general operation.

Who should book this experience

I would recommend this outing to you if you want a high-energy day on the water with several different kinds of stops. It suits first-time visitors who want to see more than Kotor Old Town, couples looking for scenic photos, and families with older children who can handle a speedboat ride.

It also suits anyone who likes a local captain rather than a large scripted cruise. Boban and Aljosa are repeatedly praised by name for their friendly manner, safe handling, and explanations. The guide quality matters here because several stops are short. A good skipper helps those brief visits feel worthwhile.

You may want another kind of outing if you are pregnant, have a mobility impairment, or weigh more than the stated limits. The experience is not suitable for pregnant women or for people over 350 pounds, or over 254 pounds depending on the applicable booking restriction shown. Check your specific option before payment because the supplied information lists both limits.

This is also not the right choice if you want a slow cultural tour with long visits at each site. Our Lady of the Rocks receives about 20 minutes, the tunnel about 5 to 10 minutes, Mamula Island about five minutes, and the Blue Cave about 30 minutes. The day favors variety over depth.

Rain does not automatically cancel the trip. Raincoats are provided if needed, but rough seas can force a route change. You should book with some flexibility, especially if reaching the Blue Cave is your main goal.

Practical tips for a smoother day

Wear swimwear under your clothes and bring a towel. Add water, sun protection, and a charged phone, since the boat includes scenic photo opportunities but does not replace your own camera.

Arrive 30 minutes early and look for the Hawaii Boat Tours Kotor sign. Confirm the meeting point because it can vary by booking option.

Ask the captain about photos once you board. Photos are available on request, rather than automatically promised for every participant.

Keep the €2 church and museum fee in mind if you want to go inside Our Lady of the Rocks. The island itself is part of the tour, but the optional interior visit costs extra.

Most important, leave room for weather changes. The captain may replace the Blue Cave or adjust the route when sea conditions are unsafe. That is the sensible choice, even if it means missing the trip’s most famous stop.

Should you book the Kotor Blue Cave tour?

Book it if you want the best all-round mix of swimming, history, and bay scenery for about $53. The modern speedboat, included equipment, fuel, and local skipper make the price fair, while the route gives you far more than a single cave visit.

I would not book it solely for a guaranteed Blue Cave swim. Sea conditions can change the plan, and several historic stops are brief. But if you can accept that uncertainty, this is a lively and well-priced way to see the Bay of Kotor from the water, with enough variety to keep the day moving.
