Blue & Green Cave,Sunj beach Small Group Tour with Speedboat

The best part of this 4-hour speedboat tour is the chance to swim straight into Dubrovnik’s Blue Cave, then snorkel at nearby caves around Kolocep Island before finishing at sandy Sunj Beach. The boat ride adds a little speed and fun, while the stops leave room to set your own pace.

I like the flexible morning or afternoon departure, and I like that the captain supplies snorkel gear, pool noodles, water, beer, and white wine. The main catch is simple: this is not a sightseeing cruise for staying dry. You should be comfortable in the water, and the sea can feel cold, especially outside the warmest summer weeks.

Key points before you book

• Blue Cave swimming: You get about 40 minutes to swim near and inside the cave area at Kolocep.
• Three Caves snorkeling: A second stop offers about 45 minutes for snorkeling in clear water and exploring by water.
• Sunj Beach break: You have roughly 1 hour and 40 minutes to relax, swim, or buy lunch and drinks.
• Small-boat feel: Some departures have only six or so people, though the official maximum is 50.
• Helpful captains: Toni, Mate, Matj, Mate, and Luka are among the captains praised for friendly service, local tips, and safe handling.
• Good value at $78.60: The price covers the boat, captain, drinks, and snorkeling equipment, but not food, towels, or sun cream.

Why the Blue Cave stop is the star

Kolocep Island is the first major stop, and the Blue Cave is the reason many people choose this trip. You reach the cave by speedboat, then have time to get into the water rather than simply viewing the entrance from a boat.

The planned swim lasts about 40 minutes. That is enough time for a few swims, photos, and a float without making the whole morning about one stop. The water is clear, and the cave walls give the setting a different feel from an ordinary beach swim.

You will need to judge the water for yourself. Several people found it cold, including in October, though many still considered the swim worthwhile. The boat carries pool noodles, which are useful if you want to float without working hard or if you are less confident in open water.

This is also where departure time matters. Early boats can reach the caves before the heaviest traffic. One morning outing had only a few boats at the cave, while later in the day more than ten boats were reported waiting nearby. If quiet water and easier photos matter to you, choose the morning option when possible.

The cave stop is not a guided archaeological visit. The appeal is natural scenery, swimming, and the simple pleasure of entering a place you could not reach on foot. Captains such as Toni have also gone into the cave with passengers, which can help you find the right route and feel more at ease.

Snorkeling around Kolocep’s Three Caves

After the Blue Cave, the boat moves to Three Caves, also on Kolocep. The schedule allows about 45 minutes here. The focus shifts from the dramatic cave setting to swimming and snorkeling in clear water.

Snorkeling equipment is included, so you do not need to pack your own mask and snorkel. That is a useful saving, especially if you are flying or moving between several Croatian towns. Bring your own towel and sun cream, though, since those are not supplied.

The exact cave names can be a little confusing. The trip description refers to Blue Cave and Three Caves, while some people describe the second swimming area as the Green Cave. In practical terms, expect several cave locations around Kolocep, with time to swim and look beneath the surface rather than a long formal tour inside each one.

This stop suits active swimmers best. You can snorkel, float on a noodle, or spend less time in the water and enjoy the view from the boat. Still, the operator specifically says the tour is not recommended for non-swimmers. There is no promise of a shallow, walk-in swimming area at the cave stops.

Sunj Beach gives the trip a slower finish

After the cave stops, you get about 1 hour and 40 minutes at Sunj Beach. This is the relaxing part of the outing, and it helps balance the faster boat ride and repeated swims.

Sunj is known for its sandy shore, which feels different from the rocky swimming spots common along the Adriatic. You can swim, sit on the beach, or stop at one of the three restaurants for food and drinks. Lunch is not included, so plan to pay separately if you want a meal.

The beach stop also gives you a chance to dry off and settle into a more ordinary seaside rhythm. People have singled out the calamari at the restaurants, but your choice will depend on what is available when you arrive. Credit cards were accepted at the beach in at least one visit, though carrying a backup payment method is still sensible.

Do note the seating arrangement. Shaded lounge chairs may require a food or drink purchase. That is not unusual at a beach restaurant, but it is worth knowing before you expect a free chair for the entire break.

The published timing lists Sunj Beach as a two-hour stop, with about 1 hour and 40 minutes described as free time. Allow for a little movement around the boat and beach rather than expecting every minute to be unstructured.

What the speedboat adds

The speedboat is more than transport between stops. The ride itself is part of the appeal, especially for anyone who likes a little wind and motion between swims. Several departures used clean, comfortable boats with enough room for a small group.

A fast boat also lets the captain cover Kolocep and Sunj Beach in a half-day outing. You do not lose a full day to the water, and you can still leave room for Dubrovnik’s old town, a meal, or another activity.

The tradeoff is exposure to the weather. On a calm day, the ride can be smooth and exciting. In wind or choppy water, it may feel less comfortable, though captains have been praised for handling rougher conditions carefully. The tour requires good weather, so a poor forecast can lead to a change of date or a full refund.

Bring sun protection that will stay secure on a moving boat. A hat, towel, and sun cream are especially useful because none of those are included. You may also want a dry bag for phones and small items, though one is not supplied.

Drinks, equipment, and what the $78.60 covers

At $78.60 per person, this is not the cheapest way to spend a few hours by the sea. It is a fair price if you plan to swim at the caves, use the snorkeling equipment, and enjoy the speedboat rather than treating the boat only as a taxi.

The package includes bottled water, beer, and white wine. Soda is also described as an available included drink. The captain may serve drinks on board after or between the swims, but do not treat the alcohol as the main attraction. You still need to stay alert around the water.

Snorkeling equipment is included, as are pool noodles on departures where they are carried. Those extras improve the value for families and mixed groups, since you do not need to rent gear separately.

Food is not included. Towels and sun cream are also excluded. Once you add lunch and drinks at Sunj, your total spending will rise, so budget for those separately.

The tour’s maximum is 50 people, but the boat can feel much smaller on some departures. Groups of six, or a handful of passengers plus a larger private party, have been reported. Ask about the expected group size if that affects your choice. The phrase small group is most accurate for departures that fill lightly, not as a guaranteed six-person limit.

The captains make a real difference

The strongest part of the human side of this trip is the captain. Toni is often praised for being friendly, helpful, and able to make the boat feel relaxed. Matj, Mate, Luka, and others have also been described as careful drivers who share information about the caves, local food, and nearby islands.

That matters on a water-based trip. A good captain does more than steer. He helps you understand where to swim, keeps an eye on changing conditions, and points you toward a sensible place to eat at Sunj.

The quality can vary by departure because different captains may operate the boat. Most feedback is highly positive, but one booking ended with the operator failing to meet the party at the pickup point. That appears to be an exception, yet it is a reason to arrive early, confirm the meeting details, and keep the company’s contact information handy.

The meeting point is Lapadska obala 4 in Dubrovnik. If you arrive by cruise ship, the walk to the dock has taken about 20 minutes for some people. That makes the tour workable from a ship, especially with the afternoon departure, but you should allow extra time for disembarkation and finding the dock.

Morning or afternoon: which departure works best?

Choose the morning if your main goal is the caves. Earlier departures give you the best chance of reaching the Blue Cave before queues build. You may also find the sea calmer early in the day, although weather conditions can change quickly.

Choose the afternoon if you are arriving from a cruise ship and do not want to rush off at the start of the day. The later option lets you ease into the morning, then spend the afternoon on the water. The drawback is that the caves and beach may be busier.

The tour ends back at the same meeting point. That makes planning easier, since you do not need to arrange a separate return transfer.

The outing lasts about four hours, but allow extra time around the departure and return. Boats run on local conditions, and the schedule includes swimming, beach time, and movement between stops rather than four exact hours on the water.

Who will enjoy this trip most?

I would choose this for a couple, family, or small group that wants several kinds of seaside activity in one half-day. It works especially well for people who do not want to spend all day on a boat but still want more than a standard beach visit.

It is also a good fit for cruise passengers. The dock is walkable from the port for people comfortable with about a 20-minute walk, and the four-hour format can fit within a port call if you allow plenty of time on both ends.

You should be a confident enough swimmer to manage open-water stops. The crew provides noodles and equipment, but those items do not turn the trip into a non-swimmer activity.

I would think twice if you dislike fast boat rides, cold water, or changing weather. The boat is comfortable, but this is an active sea outing, not a covered sightseeing vessel with a fixed view and no splashing.

Cancellation and practical details

You receive confirmation when you book, and the activity is offered in English. It is near public transportation, and most people can participate if they are comfortable with the swimming requirements.

You can cancel for a full refund up to 24 hours before the start time. Changes or cancellations inside that 24-hour window are not accepted for a refund. Since the trip depends on good weather, the operator may offer another date or a full refund if conditions force a cancellation.

Pack a swimsuit, towel, sun cream, secure footwear for getting on and off the boat, and a dry place for your phone. Alcoholic drinks are included, but drink responsibly and keep swimming ability in mind.

Should you book the Blue and Green Cave tour?

Book it if you want cave swimming, snorkeling, and a sandy beach in one well-paced half-day. The strongest value comes from the included boat ride, gear, drinks, and the chance to beat the crowds with a morning departure.

Choose the early tour for the best cave atmosphere. Choose the afternoon if you need a slower start or are fitting the outing around a cruise ship.

Skip it if you are a non-swimmer, want a quiet dry boat ride, or dislike spending extra on beach food. For everyone else, the $78.60 price is reasonable for a lively, flexible outing that combines two very different sides of the Dubrovnik coast.
