Blue Cave 3 hours GROUP tour with modern speedboat

The best part of this three-hour speedboat trip is the chance to reach the Blue Cave, a sea cave that cannot be reached by road or on foot. You can swim in its clear water, ride through old submarine tunnels at Kumbor, and visit the little island of Our Lady of the Rocks in one compact outing.

I like the small-group format, with no more than 12 passengers, and I like the flexible swimming time. Captains such as Ilija, Ivan, Peter, and Paki have been praised for good boat handling, friendly service, and useful local information. The main drawback is the ride itself: once you leave the sheltered Bay of Kotor, the small speedboat can be fast and rough.

Key points to know before booking

• The Blue Cave is the main event: You get about 20 to 30 minutes for photos and swimming, either inside the cave or just outside it.
• The sea can be rough: The ride to the cave may take about an hour and can feel choppy in wind or boat traffic.
• You see three different kinds of places: A natural sea cave, Cold War submarine tunnels, and a man-made island with a church and museum.
• Pickup can save a long walk: Cruise passengers can request pickup at the Port of Kotor, while other pickup points include Dobrota, Muo, Stoliv, and Perast.
• The group is limited to 12: That is small enough to keep the outing fairly personal, though boat capacity details should be confirmed if you are booking for a private party.
• Weather matters: Poor conditions can prevent the boat from reaching the Blue Cave, with a different date or full refund offered if the operator cancels.

What the three-hour trip actually feels like

This is not a slow sightseeing cruise. It is a brisk coastal outing in an open speedboat, built around getting from Kotor to the Blue Cave and back within roughly three hours.

You begin at Sea Stars Boat Tours on Njegoševa in Kotor, though pickup is available at the Port of Kotor and selected spots along the bay. The office is outside the old town, about a 10 to 14-minute walk from the main gates according to the operator. If you are arriving by cruise ship, port pickup is the simplest choice and saves you from searching for the office.

The boat carries up to 12 people. That is a useful middle ground: more intimate than a large sightseeing vessel, but not necessarily a private excursion. You will have a skipper rather than a dedicated tour guide, so the quality and amount of commentary may depend on the captain assigned that day.

The captains have different strengths. Ilija has been praised for making the trip enjoyable, Ivan for sharing local history, Peter for both driving and guiding, and Paki for safe handling and helpful suggestions. You should expect an informal boat tour rather than a carefully scripted history lesson.

Racing across the Bay of Kotor toward the Blue Cave

The first part of the ride takes you out from Kotor through the Bay of Kotor and toward the open Adriatic. The views are one of the strongest reasons to book this excursion. From the water, you see steep coastal slopes, old settlements, small islands, and the changing shape of the bay without having to retrace the same roads by car.

The speedboat makes the route possible in a short time, but speed has a cost. Several passengers found the ride rough, especially after leaving the protected water of the bay. Wind, wakes from other boats, and open-sea conditions can make the small boat bounce sharply.

Sit toward the back if you are sensitive to motion. One passenger specifically found the rear seats less rough when passing other boats. Hold onto your belongings, too. A pair of sunglasses was broken during a rough moment, and the operator later issued a refund, but it is wiser to secure loose items before the boat gets moving.

The boat may play music, and the skipper may slow down for photographs or point out coastal sights. Still, do not book this expecting a gentle harbor cruise. You are choosing a speedboat because it reaches the cave quickly, and the ride is part of the experience.

Swimming at the Blue Cave

The Blue Cave is the trip’s clear highlight. It is accessible only by boat, and the interior glows with blue-toned water when light enters beneath the cave opening. You have around 20 to 30 minutes for photos and swimming inside or outside the cave.

The word inside needs a little context. This is a public cave, not a private swimming site, and several boats may arrive at once. At busy times, the interior can feel crowded, making it hard to appreciate the color or move around comfortably.

If the cave is too busy, the skipper may take you to swim outside or near a smaller cave. That is not a poor substitute. The water outside is described as exceptionally clear, and you may have more room to swim, climb, or look around than you would inside the main cave.

Bring a swimsuit, towel, and sun protection. Snorkel equipment, fins, and water shoes are useful if you plan to explore around the rocks, although they are not listed as included. The operator provides blankets in winter, and raincoats have been offered during brief showers, but you should still dress for spray and changing weather.

The swimming stop is not guaranteed in every form. Heavy rain, high water, poor visibility, wind, or rough seas can make the Blue Cave unsafe or unattractive. On some outings, the captain has skipped the cave and offered other stops instead. That is the correct safety decision, but it means you should book this for the overall boat journey, not only for one photograph inside the cave.

Entering Kumbor’s Cold War submarine tunnels

After the cave, the boat heads to Kumbor, where you enter old submarine tunnels. The stop lasts only about five minutes, but it adds a completely different mood to the trip.

These narrow military tunnels were built for submarines during the Cold War. Your speedboat goes inside, giving you a close look at a piece of coastal history that is easy to miss from the main route.

This is a quick stop, not a full museum visit. The skipper may explain the site, but the amount of detail varies by captain and language ability. If you want a long historical presentation, this will feel brief. If you enjoy unusual places and a little atmosphere, the tunnel is one of the most memorable parts of the outing.

The boat’s small size is important here. A large tour vessel could not offer the same access, while the speedboat can move directly into the tunnel before continuing along the coast.

Twenty minutes on Our Lady of the Rocks

The final major stop is Our Lady of the Rocks, an artificial island near Perast. Its creation began in 1452 and continued over centuries, giving the island a long connection to local seafaring tradition and religious life.

You have about 20 minutes to explore. That is enough to walk around, take in the view, and decide if you want to enter the church or museum. Church and museum tickets are not included, so carry money if you want more than the exterior and island views.

The island is small, and the stop is less about wandering for hours than taking in a concentrated sight. From here, you get a fine view back toward Perast, one of the most attractive settlements on the bay. You can also see a peaceful natural island nearby from the boat and from Our Lady of the Rocks.

This stop helps balance the outing. The Blue Cave gives you swimming and natural drama, the submarine tunnel gives you military history, and Our Lady of the Rocks adds art, faith, and the old coastal culture of the bay.

What is included, and what you pay for

The price is about $60.46 per person. For three hours on a small speedboat, with fuel, a professional skipper, Blue Cave access, and landing at Our Lady of the Rocks included, that is a reasonable price if the sea is calm and you value seeing several sites quickly.

The value is less clear if you mainly want a long swim. Roughly an hour may be spent reaching the Blue Cave, and the cave stop itself lasts around 20 to 30 minutes. You are also paying for the boat ride, the scenery, the tunnel, and the island visit.

Included services are:

• Fuel
• Professional skipper
• Entry into the Blue Cave area
• Landing at Our Lady of the Rocks
• Coffee and water before departure
• Wi-Fi at the office
• Blankets during winter

Church and museum tickets are extra. There is no separate tour guide, so you should think of this as a skipper-led boat excursion. Some captains provide plenty of local facts, while others may offer less commentary.

At this price, the tour makes the most sense for a first visit to Kotor when you want a lot in a short time. It is less suitable if you prefer a quiet, slow boat with guaranteed access to every stop.

Small group advantages and seating concerns

A maximum of 12 passengers keeps the boat from feeling like a floating bus. You can ask questions, move more easily, and avoid the long boarding process of a large vessel.

The small group does not eliminate the limits of a small speedboat. Seating is close, and every passenger feels the motion. One outing involved a six-person boat, and the ride became uncomfortable in rough conditions. If you have concerns about motion sickness or balance, consider the sea forecast carefully and ask the operator about the boat and seating before departure.

The operator states that the activity is not recommended for people over 100 kilograms or 220 pounds and not recommended for people over 65. Most people can participate, but the combination of climbing aboard, sitting low in a moving boat, and swimming near rocky shores requires reasonable mobility.

Families should pay close attention to the weather. A rough ride may be manageable for adults but unpleasant for young children or anyone who is not comfortable on open water. A booking issue once led a family expecting a smaller private arrangement to share a boat with other passengers, so confirm the group setup directly if that matters to you.

Meeting points, cruise timing, and weather choices

The main meeting point is Sea Stars Boat Tours on Njegoševa in Kotor. Cruise passengers can request pickup at the Port of Kotor, directly beside the old town area. Pickup is also possible in Dobrota, Muo, Stoliv, Perast, and other selected locations along the route.

Give yourself time to find the office if you are walking from the old town. There may not be an obvious sign at the exact starting point, so use the map reference and ask at a local information point if needed.

The operator communicates through WhatsApp and email, and schedule changes have been handled flexibly when cruise ships arrive late. That matters if you are visiting Kotor for only one day. Even so, leave a generous buffer before your ship departure. The trip returns to the original meeting point, but road, sea, and docking conditions can change.

The tour requires good weather. If poor weather cancels the experience, you can receive a different date or a full refund. You can also cancel for a full refund up to 24 hours before the start time. A weather forecast that looks uncertain is worth discussing with the operator before you set out.

Who will enjoy this Kotor boat tour most?

You should consider booking if you want:

• A fast way to reach the Blue Cave from Kotor
• A chance to swim in clear Adriatic water
• A small group rather than a large cruise boat
• Several different sights in one morning or afternoon
• An active outing with a little history and plenty of scenery
• Convenient pickup near the cruise port

You may want another type of excursion if you dislike rough water, need a calm pace, or want detailed historical guiding at every stop. The Blue Cave can be crowded, weather can cancel the main attraction, and the speedboat may feel lively in open water.

Should you book the Sea Stars Blue Cave tour?

I would book this tour if I had three hours in Kotor and wanted a strong mix of swimming, scenery, unusual military history, and a short island visit. The best features are the compact route, small group, friendly skippers, and chance to reach the Blue Cave without arranging a private boat.

I would not book it blindly for a family member who is uneasy on boats or for anyone expecting a quiet cruise. Check the sea forecast, request port pickup if you are arriving by ship, sit toward the back, and protect your phone and sunglasses.

At around $60 per person, it offers good value when conditions cooperate. The Blue Cave itself may be busy, but the swim outside, Kumbor’s submarine tunnel, and Our Lady of the Rocks give the trip enough substance to remain worthwhile even when the main cave is crowded.
