From Kotor: Boat to Blue Cave & Lady of the Rocks &Submarine Base

Kotor Bay looks even better from the water. This three-hour speedboat trip takes you from Kotor to the Blue Cave, Our Lady of the Rocks, Perast, submarine tunnels, and Mamula Fortress, packing a lot of scenery into one morning or afternoon. I especially like the beautiful swimming stops and the chance to enter a former submarine tunnel, a sight many visitors miss from land. I also like the low price, about $32.53 per person. The main concern is crowding, along with rough seas and limited commentary on some departures.

The boat leaves from Hawaii Boat Tours at Park Slobode 1 in Kotor and returns to the same place. The operator advertises an English-language tour with mobile tickets, free cancellation up to 24 hours before departure, and a maximum of 80 participants for the activity. In practice, boat sizes described by passengers ranged from 11 to 16 people, so you should expect a shared ride rather than a quiet private cruise.

Key Points Before You Book

• The Blue Cave is weather-dependent: High water, wind, waves, or heavy boat traffic can prevent the boat from entering.
• Swimming may happen outside the cave: Captains sometimes use a nearby swimming spot when the cave is unsafe or too crowded.
• The speedboat ride can be rough: The trip outside Kotor Bay takes roughly 45 to 60 minutes each way, depending on conditions and traffic.
• The submarine tunnel is a memorable stop: You ride into a former military tunnel cut into the mountain and hear stories about its past.
• Our Lady of the Rocks is brief but worthwhile: The man-made island and church are striking, though the stop can feel crowded.
• Cruise passengers need a firm time plan: Kotor is a tender port, and the boat will not normally wait for late arrivals.

What This Kotor Boat Tour Actually Covers

This is not a slow sightseeing cruise. It is a brisk speedboat outing that links several of the Bay of Kotor area’s best-known water sights. You sit low over the water, feel every major wave, and move quickly between stops.

The advertised duration is about three hours, including travel time. That matters. A large part of the trip is spent reaching the Blue Cave and returning to Kotor, leaving short windows at the individual sights. You get variety rather than long visits.

The price is attractive for this route. At about $32.53 per person, it can be a good way to see several coastal sights without arranging separate transport. But the value depends heavily on conditions. If the Blue Cave is closed and the boat is crowded, the outing can feel less rewarding because the ride itself takes up much of the schedule.

The tour is offered in English, though the amount of spoken information can vary by captain. Some trips include useful explanations at the historic sites. Others provide little commentary or use a recording. If learning about Montenegro is your main goal, you may want to pair this with a walking tour of Kotor or Perast.

Leaving Kotor on a Shared Speedboat

The meeting point is Hawaii Boat Tours Kotor at Park Slobode 1, close to Kotor’s waterfront. The gathering area can be busy, with several operators and groups leaving around the same time. Arriving early is wise, especially since the operator asks you to arrive 30 minutes before departure.

Once aboard, expect a practical speedboat rather than a luxury vessel. Some passengers found the boats clean and comfortable enough, while others felt cramped, especially with 13 to 16 people aboard. There were also complaints about late departures, unclear staff identification, and not enough room for everyone to move freely.

Your seat matters. On a fast boat, the ride can bounce hard over wake and open-water chop. Sit securely, hold on when the boat accelerates, and bring sunscreen. You may also get wet. The ride is part transportation and part amusement park, though people with back problems or a strong dislike of rough water should think twice.

The strongest praise goes to the captains who handle the boat well. Several passengers enjoyed the way their driver adjusted speed, avoided other boats, and kept the schedule moving. Captain Boben received especially warm praise from one large family group. Other accounts describe friendly drivers who made passengers feel safe, even when the water was rough.

That experience is not perfectly consistent. A few passengers complained that the captain drove too fast, offered too little safety guidance, or seemed distracted. Since captain performance can shape the whole day, this is one area where expectations should remain practical rather than polished.

The Blue Cave: Beautiful, Crowded, and Not Guaranteed

The Blue Cave is the star of the excursion. Sunlight enters through an opening in the rock and turns the water a striking blue. When conditions are calm and the timing is good, the effect is impressive, especially from inside the cave.

The scheduled stop is about 30 minutes, but that does not mean 30 minutes inside the cave. Boats gather at the entrance, and access depends on waves, water level, traffic, and safety rules. Several accounts describe spending only a few minutes inside before moving on.

Swimming inside the cave may not be allowed. On some departures, the captain takes the group to a nearby spot outside the cave for 10 to 20 minutes of swimming or snorkeling. That substitute can still be enjoyable, with clear water and a chance to cool off, but it is not the same experience as swimming beneath the blue glow.

Weather can change the plan before or during the ride. Rain the night before, high water, or rough seas have all prevented entry. One practical frustration is that the group may only learn this after reaching the entrance. The captain then has to make the safe call, even if the Blue Cave is the main reason you booked.

Heavy traffic is another issue. At peak times, many boats may be waiting outside or inside the cave. That can shorten your visit and make swimming near moving boats feel uneasy. I would treat the cave as a welcome possibility, not a promise. If seeing it is your top priority, check the weather and sea conditions before booking, and accept that nature and local safety rules control the final result.

Bring your own swimsuit, towel, sunscreen, and perhaps a waterproof phone pouch. Snorkeling gear may be available, but equipment has not always been sufficient for everyone. Do not assume that goggles will be provided for every person in your group.

Our Lady of the Rocks and the Short Visit to Perast

Our Lady of the Rocks is a small man-made island opposite Perast. Local tradition says the island grew after sailors placed stones in the water around a rock where an image of the Virgin Mary was found. The church on the island gives the stop its strong cultural and visual appeal.

The boat generally allows about 20 minutes here. That is enough for a quick look around and photographs, though it is a short visit if you want to study the church interior or take your time. Crowds can make the tiny island feel even smaller.

The nearby town of Perast adds another layer to the outing. Its one main street is lined with Baroque buildings, old palazzos, Catholic churches, and defensive towers. From the water, the town has a remarkably preserved appearance, with steep mountains rising behind it and the bay opening in front.

The schedule does not appear to allow a long independent walk through Perast. In other words, you may see the town from the boat or receive only a brief stop, rather than having time for a full town visit. If Perast interests you most, plan a separate land visit on another day.

Entering the Former Submarine Tunnel

The submarine tunnel is one of the tour’s best surprises. The boat heads into a narrow opening in the mountain, where Yugoslav-era military forces once hid submarines and other naval equipment. Inside, the concrete structure feels stark and functional, a sharp contrast to the sunny bay outside.

The stop lasts about 10 minutes. That is enough to enter, look along the tunnel, and hear some background from the captain or guide. The tunnel is not decorated for tourists, which is part of its appeal. You are seeing a real piece of coastal military infrastructure rather than a polished attraction.

This stop also gives you a useful sense of how the Bay of Kotor was used strategically. The mountains provided natural cover, while the narrow waterways made the area valuable for naval defense. Commentary varies, so you may get an engaging story or only a few basic facts.

The boat ride into the tunnel can be a highlight even for people who are less interested in swimming. If the Blue Cave is closed, this is one of the stops that helps rescue the day.

Mamula Fortress and the Farther Reach of the Bay

The boat makes a short stop of about 10 minutes around Mamula Fortress. The circular fort sits on an island at the entrance to the Bay of Kotor and was built as a defensive stronghold. It later served as a prison, giving the site a darker past.

You usually view the fortress from the water rather than spend a long time walking through it. The captain may explain its role and tell stories about the island. The stop is brief, but the isolated setting makes it a worthwhile photo opportunity.

This is also where the ride can feel most exposed to the open sea. The water outside the inner bay is often choppier, and boat traffic can add more wake. If the ride to the Blue Cave already feels uncomfortable, the route around Mamula may not improve things.

Crowds, Timing, and the Cruise Ship Problem

The most important practical warning is for cruise passengers. Kotor uses tender boats for many cruise arrivals, and getting from your ship to shore can take much longer than expected. Some passengers have missed fixed departures after spending hours waiting to come ashore.

The operator follows a strict schedule and may not move you to a later trip if you arrive late. The stated cancellation policy allows a full refund only when you cancel at least 24 hours before departure. Changes made inside that window are not accepted, and a missed departure is not treated like a weather cancellation.

If you are arriving by cruise ship, leave a large buffer between your expected arrival at the dock and the tour departure. Do not rely on the ship’s published arrival time alone. If missing the tour would ruin your day, a cruise-line excursion may offer more protection, though it often costs more.

At the meeting point, look carefully for the correct staff and boat. The dock can be hectic, especially when several groups are gathering. Keep your booking confirmation open on your phone and arrive early enough to sort out any confusion.

Who Will Enjoy This Tour Most?

I think this trip suits you if you want to see several famous sights quickly and do not mind sharing space. It is a good match for:

• First-time visitors with only a short stay in Kotor
• Families who enjoy boats, swimming, and quick sightseeing
• People who want a low-cost route to the Blue Cave area
• Active visitors comfortable with sun, spray, and a bumpy ride
• Anyone interested in unusual sights such as the submarine tunnel

It is less suitable if you want a quiet boat, long stops, detailed guiding, or guaranteed cave entry. You should also think carefully before booking if you have back problems, dislike open-water speedboat travel, or need a flexible departure time.

The experience is strongest on calm days with a skilled captain and a manageable group. It is weakest when the cave is closed, the boat is full, and the sea is rough. Those variables are not minor details. They determine the character and value of the entire trip.

Is the $32.53 Price Worth It?

At $32.53 per person, this is one of the more affordable ways to combine the Blue Cave, Our Lady of the Rocks, the submarine tunnel, and Mamula Fortress. If the boat runs on time, the stops are open, and you enjoy the ride, the price is fair.

The value drops when you spend much of the three hours bouncing across rough water, waiting for fuel, or sitting in a packed boat. Some people also found the same type of trip available near the dock for about 30 euros, so comparing same-day prices may make sense if you are not tied to a fixed schedule.

A private boat costs more but gives you greater control over timing, space, and swimming stops. For a family or small group, the extra cost may be worthwhile. For solo visitors or couples watching the budget, the shared tour remains a reasonable gamble.

Final Verdict: Book It with Realistic Expectations

I would book this tour if you want a fast, affordable introduction to Kotor Bay and you are comfortable with a shared speedboat. The submarine tunnel, Our Lady of the Rocks, Mamula Fortress, and the chance to swim in clear water give the trip plenty of appeal.

I would not book it expecting a calm cruise, a long visit at each stop, or guaranteed entry into the Blue Cave. Check the forecast, arrive well before departure, bring sun protection and water, and understand that commentary may be brief.

For cruise passengers, the decision is more complicated. The fixed departure and strict late-arrival policy create a real risk in Kotor’s tender port. If you can reach the meeting point early, the tour can be a memorable part of your visit. If your shore time is tight, choose an option with stronger schedule protection.
