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

Blue water, wartime tunnels, and a good boat day. This Kotor speedboat trip packs the Bay of Kotor’s best coastal sights into one lively outing. I like the brand-new speedboat and the chance to swim in the Blue Cave, where sunlight turns the water bright turquoise. I also like the mix of beauty and history, from Our Lady of the Rocks to old submarine tunnels and Mamula Island. The main catch is weather: rough seas can change the route, and the ride back to Kotor takes about an hour.

The $53 price is strong value if you want several major sights without arranging separate boats, taxis, and museum stops. Skippers such as Boban and Aljosa earn especially warm praise for safe driving, good music, and clear stories. Bring swimwear, but also pack patience: this is a fast-moving day on open water, not a slow sightseeing cruise.

Key points at a glance

• The Blue Cave is the main event: You get about 30 minutes for swimming, snorkeling, and, when conditions allow, jumping into the clear turquoise water.
• The boat is part of the fun: A modern speedboat covers long stretches quickly, with music and broad views across the bay.
• History breaks up the scenery: Submarine tunnels and Mamula Island add a darker, more intriguing side to Montenegro’s coast.
• Our Lady of the Rocks includes time ashore: You have about 20 minutes to walk around and see the famous church island, while museum and church tickets cost extra.
• Perast is enjoyed from the water: The tour passes the UNESCO-listed town, giving you a fine view of its baroque waterfront without a full town visit.
• Weather can change the plan: The skipper may replace the Blue Cave or another stop if sea conditions become unsafe.

Why this Kotor boat trip works so well

Kotor’s bay is beautiful from the shore, but the full scale of it becomes clearer from a speedboat. You pass steep coastal slopes, old settlements, small islands, luxury marinas, and open stretches of sea in one outing. The boat lets you cover more ground than a walking tour, while the stops keep the day from becoming a simple ride.

This experience also has a pleasing balance. You get a little culture at Our Lady of the Rocks, a little military history at the submarine base and Mamula Island, and plenty of time for sea air and swimming. That variety makes the $53 fare easier to justify, especially if you have only a short stay in Kotor.

The boat leaves from one of two Hawaii Boat Tours Kotor locations, depending on the option you book. Look for the Hawaii Boat Tours Kotor sign and arrive 30 minutes early. Summer traffic around Kotor can be slow, and a late arrival may mean missing the boat without a refund or rescheduled place.

Speeding past Perast and its island churches

The first short ride takes you toward Perast, one of the most attractive towns on the Bay of Kotor. You pass the town rather than stopping for a full visit, so you will see its waterfront, stone buildings, and church towers from the boat.

Perast has a strong old-world character, with baroque architecture pressed between the mountains and the water. Seeing it from offshore gives you the best sense of its setting. You can take photographs without spending time on another walking stop, though anyone wanting cafés, churches, or a longer look at the town will need to return separately.

The boat then reaches Our Lady of the Rocks, the small artificial island opposite Saint George Island. You have about 20 minutes here. That is enough for a short walk, photographs, and a look at the famous church, but it is not a long cultural visit.

The church and museum are optional extras. Entry to the museum costs €2, and that fee is not included. If you want to understand the island beyond its postcard appearance, the small admission can be worthwhile. If your priority is the water and the boat ride, you can simply enjoy the views and stay outside.

Saint George Island is not a landing stop on this trip, but you get a view of its quiet, tree-covered setting. It is a peaceful contrast to the more decorated Our Lady of the Rocks. Your skipper can point out the two islands and explain how differently they developed.

WWII submarine tunnels inside the cliffs

After the island stop, the speedboat heads toward a former submarine tunnel. The ride takes you away from the gentler inner bay and toward a more secretive section of the coast. The tunnel is cut into the rock, with a dark entrance that feels far removed from Kotor’s polished waterfront.

You spend roughly 10 minutes at the tunnel, though the included details also describe the actual visit as about five minutes. Either way, this is a brief stop, not a museum tour. You enter or look into the old military structure while the skipper explains its wartime use and the stories connected with it.

The short visit works because it changes the mood. One minute you are looking at islands and church domes, and the next you are facing a stark concrete opening in the cliff. I like that the tour does not treat the bay as scenery alone. These tunnels show how the coast was used for defense and naval operations.

Do not expect a polished historical exhibition. The appeal is the setting and the sense of discovery, along with the skipper’s explanation. A guide who enjoys telling stories makes a real difference here. Boban received repeated praise for explaining the stops, handling the boat calmly, and adding useful facts without making the ride feel like a lecture.

Mamula Island and its difficult past

The boat continues toward Mamula Island, a small, fortress-topped island at the entrance to the Bay of Kotor. You get a photo stop, a guided explanation, and a pass by the island rather than a long landing visit. Plan on about five minutes.

Mamula’s round stone fortress is visually striking, but its past is grim. It was used as a WWII prison, and the site is linked with stories of harsh detention and escape attempts. The island’s position in the open sea helps explain why it was chosen. From the water, the fort looks isolated and difficult to reach.

This is one of the most useful parts of the trip for anyone who wants more than pretty views. The stop is short, but the contrast between the dramatic setting and the prison history gives the island weight. You will have time for photographs, yet you should not expect a detailed walk through the fortress.

The route may also pass Porto Novi Marina, a luxury seaside resort filled with yachts and modern waterfront buildings. It is a quick visual change from the old fortifications and small historic towns. You get the marina as part of the cruise rather than as a separate stop.

Swimming in Montenegro’s Blue Cave

The Blue Cave is the centerpiece. After another short speedboat ride, you reach the cave area for about 30 minutes of swimming. The water appears turquoise as sunlight enters the cave and reflects below the surface.

You can swim or snorkel, and the boat carries masks when available. You should bring your own mask if snorkeling matters greatly to you, since the supplied equipment is subject to availability. Life jackets are provided, and the boat also carries standard safety equipment and a first-aid kit.

This is a place where timing and sea conditions matter. The water may look its best when sunlight reaches the cave clearly, but the skipper has the final say on safety. The boat company can change the route during rough weather and visit another location instead. Several winter outings had to skip the cave because of conditions, so do not book this experience with the assumption that the swim is guaranteed.

If you are comfortable in open water, the half-hour stop gives you enough time to enjoy the setting without feeling rushed. If you prefer to remain on the boat, you can still take photographs and enjoy the unusual color of the water. Swimwear, a towel, water, and a charged phone belong at the top of your packing list.

Cliff jumping is also mentioned as an option, but treat it as dependent on the skipper, the location, and current conditions. Never assume that a jump will be available simply because it is advertised as a possibility.

The speedboat ride is part of the experience

This is not a quiet wooden boat with a slow, gentle pace. The modern speedboat is designed to get you from Kotor to the outer bay and back in a practical amount of time. The itinerary includes several fast rides, with the return journey taking about an hour.

That speed has two benefits. You can reach the Blue Cave and Mamula Island in a day without spending most of your time on the water, and you get sweeping views as the boat moves between stops. The boat itself has been praised for being clean, comfortable, and new.

The tradeoff is motion. If you are sensitive to speed, spray, or choppy water, choose a calmer day if possible and sit where you feel most comfortable. The route is not ideal for pregnant women, people with mobility impairments, or anyone over the stated weight limits of 350 pounds, or 159 kilograms, and 254 pounds, or 115 kilograms, as provided for the available options.

Music is part of the atmosphere. Boban’s song choices earned repeated praise, and several people described him as relaxed, friendly, and fun. That makes the ride feel more social and less formal. Still, if you want a silent nature trip, the music may not suit your taste.

What the skipper adds to the day

The skipper is both driver and guide, so the quality of the experience depends heavily on that person. The company provides a licensed English-speaking skipper, insurance, fuel, taxes, life jackets, and the boat. Photos are available if you ask the captain.

Boban is singled out for safe handling in rainy weather, useful facts, and a calm manner. Aljosa is praised for professionalism and for making the trip feel special. Those details matter because the tour involves open water, quick changes between stops, and a number of historical sites that have little signage of their own.

You should ask questions when you board. Ask where photographs are best taken, how long the swimming stop will last, and whether the sea conditions may affect the Blue Cave. A good skipper can also tell you what you are seeing as you pass Perast, Saint George Island, Porto Novi Marina, and Mamula.

Is $53 good value for Kotor?

At $53 per person, this is a good deal for a packed coastal day. Your fare covers the speedboat, fuel, skipper, insurance, equipment, taxes, and the main stops. You would spend more time and effort arranging separate transport to Perast, the submarine tunnels, Mamula, and the Blue Cave.

The value is strongest if you want variety. You get a historic island, a military site, a fortress, a marina, a UNESCO-listed town view, and a swim. Few half-day boat trips offer such a broad mix at this price.

The value is less clear if your main goal is a relaxed visit to Perast or a long museum experience. You only pass Perast, and the stops at the tunnel and Mamula are brief. The €2 museum entry at Our Lady of the Rocks is small, but it is one extra cost to remember.

The advertised duration ranges from 1.5 to 9 hours depending on the option and schedule. Check the exact departure time and length before paying, since the supplied route describes a much fuller outing with multiple stops. Private and small-group options are available, which may suit you if you want more room or a more personal pace.

Who should book this experience?

I would choose this trip if you want an active day with swimming, fast boat rides, photographs, and several different sights. It suits couples, friends, and families with older children who are comfortable on a speedboat and in the water.

It is also a good fit if you are staying in Kotor for only a short time. Instead of choosing between Perast, the Blue Cave, and the old military sites, you can sample all of them in one outing.

I would think twice if you dislike open-water motion, need a fully accessible boat, or want long visits at each stop. The schedule moves quickly, and the Blue Cave is weather-dependent. The route can also be modified for safety, which is sensible but means the exact experience is not fixed.

Rain does not automatically cancel the outing. Raincoats are provided, and the skipper may still operate the trip if sea conditions allow. Bring a charged phone in a waterproof pouch if you have one, since the bay offers many photo opportunities and your own protection is not listed as included.

Practical details before you reserve

You can cancel up to 24 hours before departure for a full refund, and the reserve-now, pay-later option keeps your plans flexible. The meeting point depends on the option you choose, so check the confirmation carefully rather than assuming every departure uses the same dock.

Arrive 30 minutes early. This is especially important in summer, when traffic delays around Kotor can be common. Late arrivals may not be accommodated, and limited availability means the company does not promise a refund or a new departure.

The tour runs in English. A licensed captain and crew operate the boat, and snorkeling masks are supplied subject to availability. Church and museum tickets at Our Lady of the Rocks are not included, with museum admission listed at €2.

Should you book the Blue Cave and Kotor Bay tour?

Book it if you want Kotor’s coastline in one energetic package. The Blue Cave swim, new speedboat, and mix of island, military, and coastal sights make $53 a fair price. The strongest guides add warmth and useful stories, with Boban and Aljosa especially praised for safe driving, music, and a friendly approach.

Skip it if you need a slow pace, guaranteed cave access, or a long visit inside every historic site. Weather can change the route, and several stops are short. For an active first look at the bay, though, this is a smart choice, as long as you arrive early, bring swimwear, and accept that the sea gets the final vote.
