Dubrovnik: Blue & Green Caves Private Boat Tour with Drinks

The Adriatic turns sightseeing into a swim. This four-hour speedboat outing from Dubrovnik combines the glowing Blue Cave, Koločep’s Green Caves, and a stop at sandy Sunj Beach. I especially like the chance to swim inside the Blue Cave with a guide nearby, and the unlimited water, juices, beer, and local brandy make the $73 price feel fair. The main catch is that you need to be comfortable in the water, and the Blue Cave can be crowded or less brilliantly blue than online photos suggest.

I also like the small-group feel and the modern speedboat. Guides such as Mario, Robert, Duje, Drago, and Marin have been praised for helping people through tight cave entrances, setting a relaxed tone, and keeping everyone supplied with drinks. The free GoPro camera is a useful extra, especially when your own phone should stay safely dry.

Plan on a lively outing rather than a quiet nature cruise. The sea can turn choppy, the cave ladder may be slippery, and Sunj Beach often feels too short for people who want a long beach afternoon. Still, the mix of fast boat rides, clear water, cave swims, and cliff jumping gives this trip more variety than a standard coastal sightseeing ride.

Key points at a glance

• Blue Cave swim: You enter the cave from the sea, usually with snorkeling gear and guidance from the skipper.
• Three Green Caves: Koločep offers several swimming spots, including tighter cave passages that confident swimmers can explore.
• Sunj Beach stop: You get about an hour and a half at the area’s only sandy beach, with swimming, food, drinks, and optional golf-cart exploring.
• Private speedboat setting: This is a more personal way to reach the islands than joining a large excursion boat.
• Unlimited drinks onboard: Water, juices, beer, and local rakia brandy are available on a self-service basis.
• Useful extras: Snorkeling equipment, life jackets, and a GoPro camera are included.

Starting across from Gruž Market

The meeting point is at DECK & CHEERS, on the pier just across from the Gruž Market construction site. You do not get hotel pickup, so allow time to reach the harbor on your own. Bring swimwear and a towel, and leave large bags behind because there is no room for luggage on the boat.

Once everyone is aboard, the trip begins with a cruise beneath or near the Franjo Tuđman Bridge. This opening stretch gives you a good look at Dubrovnik from the water and lets you settle into the speedboat before the swimming begins.

The boat then passes the Grebeni Lighthouse, a useful photo stop and a pretty introduction to the small islands outside the city. The fast ride is part of the fun here. You are not simply being carried from one dock to another, you are skimming across open water with the coast shifting around you.

The exact boat and guide can vary. That matters because the guide shapes the mood of the trip. Mario is frequently praised for getting everyone involved, while Robert has been singled out for guiding people through more difficult cave passages. Duje is known for calm handling around busy areas, and other skippers have been described as friendly and attentive.

Swimming into the Blue Cave on Koločep

The Blue Cave is the first major stop, with roughly 50 minutes set aside for the area. You receive snorkeling equipment and can prepare to enter the cave from the boat. This is not a dry sightseeing stop. To experience the cave properly, you need to swim.

Inside, sunlight enters through the water and gives the cave its blue glow. The effect changes with the weather, the angle of the sun, and the number of boats nearby. I would not arrive expecting the intense electric-blue color seen in every promotional photograph. Some people find the cave less dramatic in person, especially when it is crowded, but the setting is still striking.

The guide can swim with you and show you the easiest route through the entrance. Life jackets are available, and guides can assist people who are not strong swimmers. Still, the entrance can feel tight and the swim may be longer than you expect. One practical tip is to ask how far you will be swimming before leaving the boat.

Snorkeling gear adds real value here. You can look into the clear water around the cave entrance instead of treating the stop as a quick photo opportunity. If you are not a confident swimmer, use the flotation equipment and stay close to the guide. You should not feel pressured to enter every passage.

The provided GoPro is another strong feature. You can use it for underwater photos and short videos, then receive a link for downloading the images. That saves you from risking your phone in salt water and gives your group a better record of the swim.

Exploring the Green Caves and cliff-jumping spots

The next stop is the Green Cave, followed by the Three Green Caves area. About 30 minutes is listed for one Green Cave stop and around 45 minutes for the wider group of caves, though the order and exact timing can change with sea conditions.

These caves feel different from the Blue Cave. The Blue Cave is about a single glowing chamber and the anticipation of getting inside. The Green Caves give you more room to swim, look around, and choose how adventurous you want to be. The water is clear, the rock walls are close, and the boat can reach narrow areas that larger craft cannot.

This is also where the trip’s active side comes forward. You may get the chance to jump from a cliff or from a rocky ledge, depending on conditions and the skipper’s judgment. It is optional, not a requirement. Ask about the height and water depth before jumping, and do not copy another person simply because the moment feels exciting.

Some guides enter the water with the group and help people through tight crevices. That personal help is one reason this trip feels different from a boat ride where the crew stays at the helm. At the same time, the quality of the guiding can vary. One guest found the skipper more like a driver than a tour guide, while others praised guides who explained the caves and actively joined the swims.

A small practical point: the metal boarding ladder can become slippery when wet. Use both hands and take your time getting back aboard. An underwater flashlight is not required, but one can help in the darker cave sections.

Sunj Beach gives the afternoon a slower finish

After Koločep, the boat heads to Lopud and Sunj Beach for about an hour and a half. This is the only sandy beach in the area, which makes it a welcome change from the rocky swimming spots around the caves.

You can swim in the warm turquoise water, stretch out on the sand, or order food and cocktails at the beach bar. Some beach businesses offer a lounge chair and umbrella with a drink purchase, but that is separate from the tour price. Bring cash because at least one beach bar has been reported to accept cash only.

The beach stop is long enough for a swim and a break, but many people wish it were longer. If you want a full beach day with a leisurely lunch, this tour will feel rushed. If you prefer variety, the shorter stop works well because it leaves room for three cave areas and the boat ride back.

You can also rent a golf cart to see more of Lopud, including the medieval monastery and botanical garden. The monastery and garden are free to enter, but the golf-cart rental is not included. With only 90 minutes at the beach, I would choose between exploring inland and relaxing by the water rather than trying to do everything.

Sunj is also the most practical place to buy food. Food is not included onboard, so eat before departure or use the beach stop for lunch. Do not expect the crew to provide a meal simply because drinks are included.

What the private boat changes

At $73 per person, this is not the cheapest way to spend four hours around Dubrovnik. The value comes from what is bundled together: a private speedboat, an English-speaking guide, snorkeling equipment, life jackets, unlimited drinks, a GoPro, several swim stops, and a sandy-beach break.

A regular boat trip may give you a similar route, but the private setup offers more control and less crowding. Guides can anchor near a cave, wait while your group swims, and adjust the pace within the available time. One group of nine described having the boat to themselves, which shows that private does not always mean a tiny party of two or four.

The drink policy is generous. Water and juices help you stay hydrated, while beer and local rakia brandy suit the social mood. Drink sensibly, especially before swimming or cliff jumping. The boat is at its best when you can move comfortably between the water and the deck.

The speedboat itself is part of the appeal. Several people praised the modern, comfortable condition of the vessel, and the ride gives the outing a little James Bond flavor without turning it into a formal luxury charter. Music may be allowed, and one guide let the group connect a phone to the boat’s system. That will appeal to social groups, couples, and friends celebrating a birthday.

The downside is exposure to the weather. A choppy sea can make swimming difficult, even if the boat ride remains enjoyable. The water temperature and cave access can also vary by season and conditions. If swimming is the main reason you are booking, confirm conditions with the operator rather than assuming every stop will be possible.

Timing, swimming ability, and comfort

The tour lasts four hours, with morning and afternoon starting times available depending on the date. The afternoon departure has a special appeal. One group enjoyed sunset colors on the return to Dubrovnik after choosing the 2 p.m. slot.

You should be able to swim if you want the full experience. Life jackets and flotation aids help, and the guides can support less confident swimmers, but entering the caves still involves open-water swimming. The Blue Cave may feel claustrophobic to beginners, especially when other boats are nearby.

This is not a good fit if you want to remain seated and dry. It is a better match for you if you enjoy water activities, short bursts of speed, informal guiding, and the freedom to choose between swimming, snorkeling, cliff jumping, or relaxing on deck.

Families can enjoy it, but parents should judge each child’s swimming ability carefully. Young swimmers may need close supervision around the cave entrances, ladders, and cliff-jumping areas. Children should not jump simply because adults in the group are doing so.

Bring only what you need. A towel, swimwear, sunscreen, and a small waterproof pouch are sensible choices. Large bags and luggage are not allowed. The GoPro covers the main photo need, so you can keep your phone safely stored while swimming.

The parts I would weigh before booking

The strongest part of the trip is the combination of stops. You get the Blue Cave, several Green Cave areas, open-water swimming, a cliff-jumping chance, a sandy beach, and a lively boat ride in just four hours. That is a lot of variety for one half-day.

The most common limitation is time at Sunj Beach. If the beach is your priority, you may wish the boat spent less time at the caves. If the caves and swimming are your priority, the schedule is more satisfying.

The Blue Cave is beautiful, but do not judge the entire outing by its color alone. It can be crowded, dark, or less vivid than expected. The Green Caves often provide a more relaxed swim, and some people prefer them because they offer more room to move around.

The operator’s communication has also received praise when plans changed. One booking had to be moved after a boat problem, and the company arranged an afternoon replacement and stayed easy to reach by text. That does not remove the possibility of changes, but it is useful reassurance for a water-based activity.

The tour has a 4.7 rating from 814 reviews, with 89 percent giving the transport a perfect score. Those numbers fit the pattern of the experience: the boat, scenery, guides, and drinks receive the strongest praise, while complaints center on crowded caves, limited beach time, choppy water, a slippery ladder, or missing features on an individual departure.

Who should book this Dubrovnik boat tour?

I would choose this outing if you want an active half-day outside Dubrovnik and like the idea of swimming through natural caves. It works especially well for couples, families with confident swimmers, birthday groups, and friends who want a relaxed social atmosphere rather than a formal sightseeing cruise.

I would be cautious if you dislike boats, get seasick, cannot swim, or want a quiet cultural excursion. The nearby monastery and botanical garden offer a little sightseeing on Lopud, but this is mainly a sea-and-sun outing.

The $73 price is good value when you use the drinks, GoPro, snorkeling gear, and several swim stops. It is less compelling if you do not drink, do not plan to swim, and mainly want time on Sunj Beach. In that case, a beach-focused visit to Lopud may suit you better.

Should you book it?

Book it if you want Dubrovnik’s coast in an energetic, easy package: fast boat, clear water, cave swims, a sandy beach, and a friendly skipper. Choose an afternoon departure if you like the idea of softer light on the ride home, and ask for snorkeling gear and flotation aids before entering the water.

Skip it if you expect a perfectly empty Blue Cave, a long beach afternoon, or a completely dry and relaxed cruise. For confident swimmers who want variety and good value, this is one of the more enjoyable ways to use four hours around Dubrovnik.
