Blue Cave 3 hours GROUP tour with modern speedboat

The best part of this three-hour speedboat trip is reaching the Blue Cave, a sea cave you cannot access from land. You can swim inside when conditions and boat traffic allow, then swim outside in the clear Adriatic water. I also like the unusual stop at the old submarine tunnels in Kumbor and the easy visit to Our Lady of the Rocks.

I like the small-group setup, with no more than 12 people, and the option to board at Kotor’s port instead of walking to the office. The main catch is the ride itself: once you leave the sheltered bay, the speedboat can pound across open water. If you want a calm sightseeing cruise, this is not it.

Key points to know before you book

• The Blue Cave is the main event: Plan on 20 to 30 minutes for photos and swimming, though heavy boat traffic may limit time inside.
• The open-sea ride can be rough: Wind, wakes, and weather affect comfort and can force a change of plan.
• The submarine tunnels add real character: You go inside a Cold War-era naval tunnel at Kumbor for about five minutes.
• The group is limited to 12 people: That keeps the boat more personal, though the actual boat may feel compact.
• Our Lady of the Rocks is a short but worthwhile stop: You get about 20 minutes on the artificial island, with church and museum tickets extra.
• Cruise passengers have a useful pickup option: The boat can collect you at the Port of Kotor, near the Old Town.

Why the Blue Cave makes this trip worth considering

Kotor Bay gives you a fine boat ride before the main attraction, but the Blue Cave changes the day from ordinary sightseeing to something more memorable. The boat leaves the bay and heads toward the open Adriatic, where the water and rock formations feel wilder than the quiet waterfront around Kotor.

Inside the cave, sunlight filters through the water and gives it the blue glow that supplies the name. The visit is short, usually 20 to 30 minutes, and it combines photo time with swimming. You may enter the cave itself, but you should not treat that as guaranteed. It is a public cave, not a private attraction, and several boats can arrive at once.

That detail matters. During busy afternoon departures, boats may queue near the entrance or occupy the inside chamber. The captain may take you in briefly, or keep the boat outside while you swim nearby. The water outside remains a strong part of the experience, with a smaller cave available in some conditions for extra exploring.

I would bring a swimsuit, towel, water shoes, and your own snorkel gear if you have it. The supplied information does not promise snorkel equipment, fins, or water shoes. You may want to climb around rocks or jump into the water, so secure footwear is more useful than ordinary flip-flops.

The speedboat ride from Kotor

The boat is modern and fast, which lets the tour cover several distant sights in three hours. That efficiency is the reason you can combine the Blue Cave, Kumbor’s submarine tunnels, and Our Lady of the Rocks in one outing.

It also creates the tour’s biggest drawback. The route takes you through Kotor Bay and out onto the open sea. Wind and waves can make the ride choppy, particularly beyond the sheltered water. Some passengers found the crossing rough, and one reported breaking sunglasses after hitting a wake. Keep loose belongings secure and hold on when the boat is moving.

The rear seats can feel less rough when passing other boat traffic, according to one useful tip from the trip. I would still ask the skipper where the smoothest seats are before setting off. The boat may be small, and the maximum group size does not mean you will have a spacious deck.

The pace is also brisk. This is transport with scenery, not a slow cruise that pauses at every attractive headland. Captains may slow down for photographs, and one captain stopped so a passenger could photograph a former prison now used as a hotel, but you should not expect long viewing stops unless they are part of the schedule.

Blue Cave swimming and boat traffic

The Blue Cave works best as a swimming stop rather than a formal cave tour. You board the boat, enter if possible, take photographs, and get time in the water. The captain handles the boat, but this is not a guided cave walk and there is no separate tour guide included.

The cave can be crowded, especially in the afternoon. You might find the entrance busy enough that the best option is to swim outside instead. That is not a wasted visit. The water around the cave is clear, and swimming in open Adriatic water gives you a better chance to stretch out than swimming inside a small chamber shared by several boats.

Weather can change the plan entirely. Strong wind, rain, rough seas, or poor water conditions may prevent the boat from reaching the cave. In that situation, the skipper may offer other stops or swimming options. On some departures, the cave visit has been replaced with another enjoyable route around the bay.

This is a sensible safety choice, not a minor scheduling issue. The trip operator has warned passengers in advance when the weather looked uncertain and offered the chance to cancel. If your heart is set on entering the Blue Cave, check the forecast and keep your schedule flexible.

Kumbor’s submarine tunnels

After the open-water portion, the boat heads to Kumbor, where you enter a submarine tunnel built for naval use during the Cold War. The stop lasts only about five minutes, but it gives the outing something most Blue Cave trips do not have.

The tunnel is dark, narrow, and plain compared with the bright cave and the church island. That is exactly why it is interesting. You are seeing a practical piece of military infrastructure rather than a polished monument prepared for sightseeing. The boat goes inside, giving you a quick look at how the coastline was once used for defense.

Do not expect a long historical presentation. The tour does not include a dedicated guide, and the quality of spoken commentary depends on the captain and the day’s group. Captains including Ivan, Peter, Paki, and Ilija have been praised for explaining local history, while one passenger received little information about the sites along the route.

I would ask questions if you want context. A friendly skipper may explain more when the sea is calm and the group is interested. The tunnel itself is still easy to appreciate without a lecture.

Our Lady of the Rocks and the view toward Perast

The final major stop is Our Lady of the Rocks, an artificial island opposite Perast. The island was built over centuries, from 1452 to 1722, and its small church and museum give you a chance to step ashore after the speedboat ride.

You have about 20 minutes to explore. That is enough for a walk around the island and a look at the church exterior, but not enough for a leisurely visit if you also want to see the museum. Church and museum tickets are not included, so carry some money if you want to go inside.

The island is also a good place to look back toward Perast. From the shore, you get a wide view of the old town, the bay, and the nearby natural island that you pass without stopping. The natural island is visible from the boat and from Our Lady of the Rocks, but it is not part of the walking portion.

This stop adds balance to the trip. The Blue Cave is about water and natural drama. Kumbor is about military history. Our Lady of the Rocks gives you architecture, a short island walk, and a calmer final pause.

What the $60.46 price includes

At $60.46 per person, the tour is priced as a compact sightseeing package rather than a simple boat transfer. Fuel, the professional skipper, entry to the Blue Cave, entry to Our Lady of the Rocks, and the boat ride are included.

You also get free coffee and water at the company office before departure. Wi-Fi is available there, and blankets are offered in winter. Church and museum tickets are extra, as is anything you choose to buy during the stops.

I think the price is fair if you want to see the cave and the wider bay in a limited amount of time. Hiring a private boat would cost more, while a slower standard cruise would not provide the same access to the Blue Cave. The value is strongest for cruise passengers or people with only one free morning or afternoon in Kotor.

The tradeoff is comfort. You are paying for speed and access, not a large seat, a covered lounge, or a relaxed narration throughout the route. If rough water makes you miserable, the same money may be better spent on a slower bay cruise.

Meeting point, pickups, and timing

The main meeting point is the Sea Stars Boat Tours office on Njegoševa in Kotor. The activity ends back there. The office is not inside the Old Town, and the walk from the Sea Gate is about 14 minutes at an easy pace. From the Gurdic Gate, it is about 10 minutes.

For cruise passengers, pickup is available at the Port of Kotor in front of the Old Town. That is the simplest choice if you have a ship departure to catch. Pickup can also be arranged in Dobrota, Muo, Stoliv, Perast, and other specific locations along the route from Kotor.

Confirm your exact pickup place before the day of the tour. One practical problem reported by passengers was difficulty finding the office because there was no obvious tour sign. The operator has generally communicated through WhatsApp, and that is useful for confirming the meeting instructions.

The tour takes about three hours, but allow extra time around it if you have a cruise schedule or a fixed restaurant reservation. Sea conditions, boarding, and pickups can affect the pace. The operator says the tour is usually booked well in advance, with an average booking lead time of 47 days, so reserve early in the busy season.

Who will enjoy this boat trip most

I would choose this tour if you want a lot of scenery and several distinct sights without giving up a full day. It suits confident swimmers, active couples, families with older children, and cruise passengers who want something more memorable than a bus ride.

You should be comfortable with a fast, open boat. The operator does not recommend the experience for people over 100 kilograms or for those older than 65. Most people can participate, but the small boat, boarding, swimming, and rough water deserve honest consideration.

This is not the best choice for anyone who needs a gentle ride, has limited mobility, or wants extensive historical commentary. There is no dedicated guide included, and the amount of explanation depends on the captain. You may get a lively mix of local facts and music, or a quieter ride with only basic information.

Bring a light rain jacket even in good weather. One captain handed out raincoats when a brief shower hit on the return ride, but you should not rely on that. Waterproof your phone, sunglasses, and camera before leaving the bay.

Weather, cancellations, and cruise-day planning

The tour requires good weather. If poor conditions cause a cancellation, you can choose another date or receive a full refund. You can also cancel for a full refund if you do so at least 24 hours before the start time. Changes or cancellations inside that 24-hour window are not accepted.

For a cruise visit, book early enough to secure a time that leaves a generous buffer before all-aboard. The operator has adjusted departure times and pickup locations when cruise delays occurred, which is helpful, but no boat excursion can remove the risk of changing sea conditions or port schedules.

If the forecast is uncertain, contact the operator rather than assuming the trip will run exactly as advertised. A weather-related change may mean missing the Blue Cave but still seeing the tunnels, Perast, or Our Lady of the Rocks. Decide in advance if that alternative would still make the trip worthwhile for you.

Should you book the Sea Stars Blue Cave tour?

Book it if the Blue Cave is high on your Kotor wish list and you want to add the submarine tunnels and Our Lady of the Rocks in the same short outing. The best parts are the direct access to the cave, the chance to swim, the unusual Kumbor stop, and the small-group format.

Skip it if you want a quiet boat ride or if you are uneasy in rough open water. The cave may be crowded, the crossing can be hard on a small boat, and historical narration is not guaranteed at every departure.

For the best chance at a comfortable trip, choose a time with favorable weather, use the port pickup if you are on a cruise, sit toward the rear if the captain recommends it, and bring water shoes and waterproof storage. At $60.46, it is a strong value for an active half-day experience, provided you understand that the sea, not the schedule, has the final word.
