Dubrovnik: Blue & Green Caves Private Boat Tour with Drinks

The best part of this four-hour trip is simple: you get off the boat and swim into Koločep’s caves, rather than just pointing a camera at them from the deck. Blue Cave is the headline stop, but the quieter Green Caves often provide the better swimming. A fast, modern speedboat, a small private group, and free drinks make the outing feel more personal than a standard harbor cruise.

I especially like two things here. First, the guides, including Mario, Duje, Robert, and Drago, seem to make a real difference by leading people through tight cave entrances and helping nervous swimmers. Second, the tour ends at Sunj Beach, one of the few sandy beaches in the area, giving you time to swim, eat, or simply dry off in the sun.

The main catch is that this is an active boat trip, not a sightseeing ride. You need to swim for parts of it, Blue Cave can be crowded, and time at Sunj Beach may feel short. Rough water can also change how much swimming you manage.

Key points to know before booking

• Swim into the Blue Cave: The guide leads you from the boat through clear water into the cave, with snorkeling equipment and flotation aids available.
• Green Caves can be the quieter highlight: You visit several cave areas around Koločep, where the water is often calmer and less crowded than at Blue Cave.
• Private speedboat setting: You avoid a large excursion boat and can enjoy a more relaxed group atmosphere, with room to move around the boat.
• Unlimited drinks are included: Help yourself to water, juices, beer, wine, and local rakia during the trip.
• Sunj Beach gives you a proper beach stop: You get about an hour and a half for swimming and free time at the region’s notable sandy beach.
• Bring only swimming gear: Swimwear and a towel are essential. Large bags and luggage are not allowed.

A fast departure from Dubrovnik’s Gruž harbor

The tour begins at Deck & Cheers, on the pier across from the Gruž Market construction site. There is no hotel pickup, so plan time to reach the meeting point on your own. The boat then leaves Dubrovnik harbor and heads along the coast, giving you an early look at the Franjo Tuđman Bridge and the Grebeni Lighthouse.

The speedboat is a big part of the experience. You cover the distance to Koločep quickly, and the ride itself supplies wide sea views and a pleasant sense of motion. It also means you spend less of a four-hour tour simply getting from one stop to the next.

The boat is described as new and well maintained, and several guides are praised for careful handling around narrow cave entrances and crowded areas. That matters here. The quality of the skipper affects both your comfort on choppy water and your confidence when the boat gets close to rock walls.

The private format is appealing for couples, families, and groups of friends. It does not mean you can redesign the entire route, but it does give the outing a more relaxed feel than sitting shoulder to shoulder on a large boat. Some guides also allow music from a passenger’s phone, adding a casual party-boat touch without turning the whole trip into a loud nightclub cruise.

Swimming into Koločep’s Blue Cave

The first major stop is Blue Cave on Koločep Island, with about 50 minutes scheduled for the area. You receive snorkeling gear before getting into the water, and the guide can lead you toward the entrance and through the cave.

This is not a dry cave visit. To see it properly, you must swim. Life jackets are available, and guides can assist people who are not strong swimmers, but the distance through the water can still feel demanding. One practical point is easy to miss when looking at glossy photographs: even a confident swimmer may want a flotation aid for the return journey, especially if the sea is moving.

Inside, the attraction is the change in light. Sunlight enters through the cave opening and gives the water a blue glow, though the effect depends on weather, sea conditions, time of day, and the number of boats nearby. Do not expect every photograph online to match the scene in front of you. Some people find the cave less intensely blue than expected, and the entrance can feel crowded or slightly claustrophobic during busy periods.

That does not make the stop a failure. The experience is still more memorable when you are in the water, looking back toward the opening, than when you remain on the boat. Guides such as Mario and Robert are particularly useful here because they can show you where to enter and help you through tighter sections.

You can also use the provided GoPro. The operator supplies a camera and later sends a link for downloading the images and videos. Ask about it early, since you will want to have it ready before swimming away from the boat. An underwater flashlight may also help in the darker sections, although it is not included in the tour.

Cliff jumping and the Green Caves

After Blue Cave, the boat continues around Koločep for more rock scenery and swimming. Cliff jumping is advertised as part of the fun, but it is optional, and the exact opportunity can depend on conditions and the guide. Do not feel pressured to jump. You can remain on the boat or swim at a safer spot.

The Green Cave portion lasts about 30 minutes, followed by a visit to the Three Green Caves area for roughly 45 minutes. The schedule can sound repetitive on paper, but the stops serve different purposes. One may be a short scenic visit, while another gives you more time to swim, snorkel, or enter a narrow opening with the guide.

For many people, these green-lit rock spaces are the most enjoyable part of the tour. They are less about one famous photo and more about moving between clear-water pockets, shaded walls, and small cave entrances. The water around the caves is the real star, and the guide’s judgment matters when deciding which openings are sensible to enter.

You should expect to get wet several times. Wear swimwear from the start, keep your towel within reach, and leave large bags behind. Wet feet also make the boat ladder slippery, so use the handrail and take your time when boarding. A few passengers have found the metal ladder difficult to grip when wet, a small but useful warning for children and anyone unsteady on their feet.

Sunj Beach, Lopud’s sandy break

The final major stop is Sunj Beach on Lopud, with about an hour and a half for free time. In a region better known for pebbles and rock shelves, a sandy beach feels like a welcome change. You can swim in the warm water, sit on the shore, or have food and drinks at the beach area.

Food is not included, so bring money if you want lunch or a cocktail. Cash is a sensible choice because the beach bar has been reported to accept cash only. A drink purchase may also provide access to a lounge chair and umbrella, depending on the beach bar’s arrangement at the time.

You can rent a golf cart to see more of Lopud, including the medieval monastery and botanical garden. Both are listed as free to enter, but using the cart and fitting in extra sightseeing will take time away from the beach. On a four-hour tour, I would treat the island visit as a chance to swim and relax rather than try to cover every attraction.

The beach stop is also where the schedule can feel tight. Several people have wished for more time at Sunj, especially after spending much of the earlier tour in the water. If beach lounging is your main goal, book a dedicated beach outing instead. If you want caves first and a sandy finish second, the timing works well.

Drinks, music, and the private-boat mood

The included drink policy is unusually generous for a short boat excursion. You can serve yourself water, juices, beer, wine, and local rakia, also called brandy. The operator describes it as fair self-service, so the point is refreshment and social fun, not a formal bar service.

This adds real value. Drinks in Dubrovnik and on popular beaches can quickly push up the cost of a day out, while this tour keeps water and several alcoholic options on board. Still, drink responsibly. Swimming through caves, climbing a ladder, and riding a speedboat are not good activities to combine with heavy drinking.

The atmosphere depends partly on your guide. Mario is often singled out for getting everyone involved, playing music, and joining the water activities. Duje is praised for calm boat handling and information about the islands. Robert has been especially helpful with tighter cave passages. Other guides, including Marin, Drago, Ivan, Michael, and Carlo, are also named positively for their friendly and careful approach.

You may be able to connect your phone to the boat’s music system, but this is not a guaranteed feature. The private setting can suit a group that wants conversation, swimming, music, and a few drinks without the fixed feel of a large cruise.

How much value do you get for $73?

At $73 per person, the price is fair if you plan to use the swimming stops and the included drinks. You are paying for a private speedboat, a guide, snorkeling equipment, a GoPro, several cave visits, transport between islands, and free time at Sunj Beach. Buying drinks separately and arranging boat transport on your own could cost more, especially in high season.

The value is strongest for a group that wants several activities in one outing. You get a boat ride, cave swimming, snorkeling, possible cliff jumping, a beach stop, and refreshments without committing to a full-day cruise. Four hours is long enough to see a lot while short enough to fit into a busy Dubrovnik schedule.

The value is weaker if you dislike swimming or want extensive time ashore. You are paying for access to places that are best reached from the water. If you stay on the boat at every cave and spend only a short time at Sunj, the experience may feel expensive.

The private format also needs a little clarification. It is marketed as a private group option, but the exact group arrangement should be checked at booking. The strongest part of the offering is the smaller, more personal boat setting, not a luxury yacht with formal service.

Choosing the best time and preparing well

The tour runs for four hours, with starting times subject to availability. An afternoon departure can be attractive. One group using the 2 pm slot enjoyed the changing light and sunset colors on the return to Dubrovnik. A morning trip may offer a better chance of reaching the Blue Cave before the busiest period, but cave traffic and weather still vary.

Bring:

• Swimwear
• A towel
• Sun protection
• Cash for food, drinks, or beach extras
• A phone or camera, if you want an extra way to record the trip

Do not bring luggage or large bags. Space on a speedboat is limited, and wet equipment makes bulky baggage awkward.

You should also think honestly about your swimming ability. The guide can help non-swimmers and life jackets are available, but the Blue Cave requires time in the water. If you are uneasy, tell the guide before entering and use the flotation equipment. Parents should explain to children that the cave swim is not the same as walking into a dry cave.

Weather has a direct effect on the outing. Choppy seas can make swimming harder and may change how long you stay in certain spots. The guides appear willing to adjust the experience for safety, but no boat tour can promise ideal water, perfect cave lighting, or a quiet entrance.

Who will enjoy this tour most?

I would recommend it to active couples, groups of friends, and families with confident swimmers who want a compact taste of the islands near Dubrovnik. It suits people who prefer a boat with personality over a formal sightseeing cruise.

It is also a good match if you like variety. You are not spending four hours at one beach or one cave. Instead, you move from bridge views and lighthouse scenery to cave swimming, cliff-jump possibilities, and a sandy beach.

I would be more cautious about recommending it to anyone who cannot swim comfortably, dislikes fast boat rides, or wants a slow cultural tour. The medieval monastery and botanical garden on Lopud are optional extras, not the main focus. The tour gives you a taste of the islands, not a detailed visit to their historic sites.

The 4.7 rating from 814 reviews reflects the broad appeal of the outing, but the recurring cautions are worth taking seriously: Blue Cave can be crowded, the blue color may not match edited online photos, beach time can feel short, and the water may be too rough for easy swimming. One person also found that the GoPro and cliff jumping were not available as expected, so confirm those features with the operator if they are central to your plans.

Should you book the Blue and Green Caves tour?

Book it if you want an active half-day on the water and will make full use of the cave swims, snorkeling gear, GoPro, beach stop, and unlimited drinks. The guides are a major strength, and the small speedboat format makes the trip feel more personal than a standard group cruise.

Skip it if your priority is a long, quiet beach afternoon, a dry sightseeing boat ride, or a guaranteed cliff jump and perfect blue cave lighting. For everyone else, $73 is a reasonable price for a lively four-hour outing that combines Koločep’s caves with Lopud’s sandy Sunj Beach.
