Dubrovnik: Blue & Green Caves Private Boat Tour with Drinks

The best Croatian memories may happen offshore. This four-hour speedboat trip combines swimming inside Kolocep’s Blue Cave with relaxed stops at the Green Caves and Sunj Beach. I like the small-group feel, the modern boat, and the unlimited beer, rakia, water, and juice. I also like that guides such as Mario, Duje, Drago, and Robert often get into the water to help you through tight cave openings.

The main catch is simple: this is not a quiet sightseeing cruise. You need to swim for some parts, the Blue Cave can be crowded, and the time at Sunj Beach may feel short. At $73 per person, it is good value if you want an active boat outing with drinks and several swim stops, but less so if your main goal is a long beach afternoon.

Key points to know before you book

• The Blue Cave visit involves swimming: Life jackets and flotation aids are available, but you still need to get into the sea and swim toward some cave entrances.
• The Green Caves can be the real highlight: They offer open-air swimming spots and, at times, a calmer experience than the Blue Cave.
• The private speedboat makes the route feel flexible: Your guide can take you into narrow cave sections and adjust how the group uses its swim time.
• Drinks are included throughout the boat ride: Beer, local rakia brandy, water, juices, and soft drinks are available on a self-service basis.
• Sunj Beach is the final long stop: You get about an hour and a half for swimming, relaxing, food, or a drink at the beach bar.
• The GoPro is a useful extra: A camera is provided, with a link to download the photos and videos afterward.

Starting at Gruz and heading out by speedboat

You meet at Deck & Cheers, just across from Gruz Market and the construction site, on the pier. Hotel pickup is not included, so allow time to reach the harbor on your own and look for the correct pier area.

The first part of the ride gives you a quick look at Dubrovnik from the water. You pass under or near the Franjo Tudman Bridge, then cruise by Grebeni Lighthouse. These are scenic ride-by points rather than long stops, so keep your phone ready if you want pictures.

The speedboat is a big part of the appeal. You get the wind, the quick ride, and a better sense of the islands than you would from a standard enclosed boat. Several people praised the condition and comfort of the newer boats, while guides were often singled out for professional handling in busy areas.

There is also a social side to the trip. Music may be played from a phone, and the atmosphere can become lively, especially with drinks flowing. That makes this a good fit for couples, families with older children, and groups of friends who want more energy than a formal sightseeing cruise.

Kolocep’s Blue Cave and the first swim

Kolocep Island is the first major stop, with roughly 50 minutes set aside for the Blue Cave. You receive snorkeling equipment, then swim from the boat toward the cave with your guide.

The effect inside depends heavily on sunlight, sea conditions, and how many boats are nearby. When the light reaches the water at the right angle, the cave takes on the blue glow shown in photographs. When the cave is crowded or the light is weaker, the color can be more subdued. One useful expectation: the real cave may look less dramatic than highly edited social media images.

You should also expect a narrow and somewhat enclosed swim. Strong swimmers may find it easy, but less confident swimmers can feel uneasy, especially if several people are entering at once. Life jackets are available, and guides have helped non-swimmers and nervous swimmers through the route. Still, listen carefully before leaving the boat and ask how far you will swim.

Guides make a real difference here. Robert, Mario, and other skippers were praised for entering tight sections with the group and showing people the safest way through. That personal help is one reason this private format works better than simply anchoring near a cave and leaving you to work it out.

Bring a waterproof phone case if you have one. The provided GoPro is an especially good feature because it can capture the parts of the swim that are hard to photograph with a regular phone. The operator provides a download link afterward, according to the information supplied for this activity.

Green Caves, cliff jumping, and open-water fun

After the Blue Cave, the boat continues toward the Green Caves. The schedule includes about 30 minutes at one Green Cave stop, followed by about 45 minutes around the Three Green Caves area.

The name covers a group of sea caves and openings rather than one single chamber. You may see brighter open water, rock walls, and places where the boat can get close to the formations. The Green Caves often feel less claustrophobic than the Blue Cave, and several people preferred them because there was more room to swim and less pressure from boat traffic.

The tour also advertises cliff jumping. This is an optional thrill, not something you need to do. If you want to jump, confirm the spot and the water depth with your guide first. Conditions and the exact activity can vary, and one reported experience did not include the advertised cliff jumping or GoPro. That makes it sensible to treat both as included possibilities rather than guaranteed performances.

You may also jump from the boat, float with a pool noodle, or simply stay aboard and watch. Snorkeling gear is included, but an underwater flashlight could help inside darker sections. The cave interiors can be very dim, so do not expect a full underwater show in every opening.

The boat ladder deserves care. One person found it slippery when wet, so use the handrail and take your time getting back aboard. This is a small point, but wet feet, moving water, and a metal ladder are not a good combination for rushing.

Sunj Beach on Lopud: sand, swimming, and lunch

The final major stop is Sunj Beach on Lopud, reached after the cave visits. The stop lasts about an hour and a half, making it the longest chance to slow down.

Sunj is notable because it is the only sandy beach in the area described for this tour. The warm turquoise water is shallow enough for a relaxed swim, and the sand offers a welcome change after climbing in and out of the boat.

There is a beach bar where you can buy food, cocktails, and drinks. Food is not included in the tour price, so plan to pay separately if you want lunch. Bring cash, since at least one beach bar was reported to accept cash only.

A practical tip from several visitors: buying a drink may provide access to a lounge chair and umbrella. Ask at the beach bar before settling in, since this arrangement may depend on the bar and current conditions.

Some people wanted more time at Sunj Beach. That is the tradeoff built into a four-hour tour that visits several caves. You see more places, but you do not get a full beach day. If your priority is swimming, the boat stops help make up for the shorter beach stay. If your priority is sunbathing, a separate beach visit may suit you better.

Lopud also offers more than sand. You can rent a golf cart to see parts of the island, including the medieval monastery and botanical garden, both described as free to enter. In practice, the cave schedule may leave limited time for a full island outing, so ask your guide about timing before renting anything.

Drinks, equipment, and the private-tour feel

The free drinks are more valuable than they might first sound. You can help yourself to beer, local rakia brandy, water, juices, and soft drinks while the boat is underway or anchored. Several people specifically praised the generous supply, and it helps make the $73 price easier to justify.

Drink sensibly, especially before swimming. Rakia is strong, and the tour includes several water activities. The best version of this trip is one where you enjoy a beer after getting back aboard, not one where you make a cave swim harder than it needs to be.

Snorkeling equipment is included, and life jackets are available. You should still bring your own swimwear and towel. Large bags and luggage are not allowed, so carry only what you need for the boat and beach.

The private group option adds comfort and control. You are not packed onto a large excursion boat, and your guide can keep an eye on different swimming abilities. The experience may still feel lively, especially when music and drinks are involved, but it is more personal than a standard group cruise.

Communication between the operator and customers was also praised. One booking had a boat problem and was shifted to another afternoon departure with helpful text communication. That kind of flexibility matters in Dubrovnik, where weather and sea conditions can affect water activities.

How the timing changes the experience

The tour lasts four hours, but the mood can change depending on your departure time. A 2 p.m. start was praised because the return ride caught the sunset and avoided the harshest midday feel.

An earlier start may help if you want cooler conditions and a better chance of reaching the Blue Cave before peak boat traffic. An afternoon start may give you warmer water and softer light later in the day. The Blue Cave is not guaranteed to be empty at either time, so choose based on your wider Dubrovnik plans.

The route also depends on the sea. Choppy water can make swimming difficult, even when the boat ride remains enjoyable. If swimming is central to your plans, keep a little flexibility in your schedule and avoid booking this as the only activity you care about.

Is $73 a fair price?

At $73 per person, the cost is reasonable for a four-hour private speedboat outing that includes a guide, fuel-based sightseeing, snorkeling equipment, drinks, and GoPro use. You also visit several different locations rather than spending the whole time at one cave.

The value is strongest for people who would otherwise pay separately for a boat trip, snorkeling rental, beach drinks, and photo service. The included drinks alone can add up quickly in Dubrovnik.

The price is less attractive if you do not drink, do not want to swim, or would rather spend most of the afternoon on Sunj Beach. Food is extra, beach rentals may be extra, and there is no hotel transport. Those costs are easy to overlook when comparing tours.

With a 4.7 rating from 814 reviews and 89 percent of ratings giving the transport a perfect score, the overall record is strong. The praise centers on the boats, the guides, the relaxed atmosphere, the caves, and the amount of drink service. The repeated drawbacks are also clear: limited beach time, occasional crowding, subdued cave color, choppy water, and occasional differences between the advertised extras and what happens on a particular trip.

Who should book this Dubrovnik boat tour?

I would choose this for an active half-day on the water. It suits you if you want to swim, snorkel, try a cave entrance, enjoy a speedboat ride, and finish with sand and a beach bar.

It is especially good for:

• Couples wanting a scenic outing with a little adventure
• Families with older children who can manage open-water swimming
• Friends who enjoy music, drinks, and a social boat atmosphere
• Confident swimmers who want to explore narrow cave openings
• Solo visitors who want a ready-made group and a guide-led experience

I would think twice if you dislike boats, get nervous in enclosed spaces, or want a slow beach day. The Blue Cave swim is not ideal for someone who cannot swim unless they are comfortable using flotation support and following close guide assistance.

The English-speaking guides are often a major part of the experience. Mario was praised for getting people involved, Duje for professional driving and local information, Robert for helping with tricky cave passages, and Drago for a calm presence. Your exact guide will vary, but the operator’s strongest feature is the personal attention from the skipper.

Final verdict: book it if you want caves more than beach time

You should book this tour if the idea of swimming into a glowing cave, exploring Green Cave openings, jumping from a rock or boat, and riding a private speedboat sounds better than sitting still for half a day.

The tour is not perfect. Cave lighting is natural, not filtered for social media. The Blue Cave may be crowded, Sunj Beach may feel rushed, and water conditions can change the plan. Still, the mix of cave swimming, comfortable transport, friendly guides, free drinks, snorkeling gear, and beach time gives you a lot for $73.

My practical choice would be the afternoon departure if you like sunset views and a more relaxed pace. Bring a towel, swimwear, a small bag, cash for the beach, and a waterproof way to carry your phone. Then let the guide handle the tight cave sections while you enjoy the sea.
