Blue & Green cave,Šunj beach – with drinks small group speedboat

The best part of this four-hour speedboat trip is its simple pairing: glowing cave water around Kolocep Island, followed by an easy stretch of sand at Sunj Beach on Lopud. You get two very different tastes of the Dubrovnik islands without giving up a full day.

I like the generous time at both cave stops, roughly 30 to 35 minutes each, and the relaxed 90 minutes at Sunj. I also like the guide-led format. Skippers such as Maro, Jakov, Antun, and Paulo have been praised for friendly service, good local advice, and careful handling when the sea turns choppy.

The main thing to weigh is the small speedboat. It can feel personal and quick, but not especially spacious when the boat is full. Equipment reports also vary, so confirm what is actually on board before leaving the port.

Key points to know before you book

• Two cave stops on Kolocep: Swim into the Blue Cave and explore the Green Caves, with time for rock jumping where conditions allow.
• Sunj Beach is more than a quick photo stop: You get about 90 minutes for shallow-water swimming, sand, beach bars, or a meal uphill.
• Small-group atmosphere: The booking allows up to 20 people, with a total tour capacity listed at 30, though some departures are much smaller.
• Drinks are included: Bottled water, soda, and alcoholic beverages are part of the package, but the exact selection and quantity can vary.
• Morning or afternoon departures: A half-day schedule leaves room for other Dubrovnik plans.
• Weather matters: Rough water can change the cave plan, and poor weather can lead to a new date or a refund.

Why this half-day boat trip works so well

Dubrovnik is best appreciated from the water. The old city walls are the headline sight, but the Elaphiti Islands give you a quieter look at the coast, with clear water, small coves, low-key beaches, and rocky shores shaped by the sea.

This excursion keeps the plan focused. You are not asked to spend a full day moving between many islands. Instead, you get two cave visits on Kolocep and a proper beach break on Lopud. That balance is valuable in the hot months, when four hours in the sun can feel just right.

I also like the choice of departure time. A morning trip may help you reach the caves before larger boat groups, while an afternoon departure can work well after a morning in Dubrovnik’s old town. The available schedule gives you some control over how the excursion fits into your stay.

At $78.64 per person, this is not the cheapest way to reach the islands. Still, the price includes the boat, fuel, skipper, taxes, water, soft drinks, alcoholic beverages, and snorkeling equipment. You are paying for a guided outing rather than simply a ferry ride, and the value is strongest if you plan to swim at the caves instead of only viewing them from the deck.

Finding the boat at Lapadska obala 4

The meeting point is the Petar Sorkocevic Summerhouse at Lapadska obala 4, near Dubrovnik Port. There is no hotel pickup, so you need to make your own way there. The activity returns to the same meeting point at the end.

Use the exact address rather than relying only on the name of the summerhouse. Most people have found the dock without trouble, but one account described confusion and having to ask around before finding the correct boat. That is an avoidable nuisance, especially if you are trying to board on time.

The boat ride itself is part of the appeal. A speedboat gets you out toward the islands quickly and gives you open views along the coast. The trade-off is that speedboats tend to have limited shade and less room to move than larger excursion boats. If the water is rough, you may feel the motion more clearly.

The operator describes the trip as small group travel. That can mean a more direct relationship with your skipper, easier questions, and less time spent organizing a large crowd. But the term should not make you expect a private yacht. The listed capacity can reach 30 people, and one boat is described as an eight-meter vessel suited to about eight to ten people. Ask about the expected group size if personal space is important to you.

Kolocep’s Blue Cave and Green Caves

Kolocep is the first stop, and this is where the tour earns its keep. The island is known for rocky shores and clear water, with cave formations that look different from the open sea than they do from inside.

The Blue Cave gets its color from reflected sunlight on the water. Entering it by swimming gives you a close view of the changing blue tones, rather than a quick look from a passing boat. Conditions, light, and sea movement affect how strong the color appears, so do not expect the same effect every hour of the day.

You have about 30 to 35 minutes at this stop. That is enough for a swim, photographs, and time to take in the cave without turning the visit into a rushed splash. It is also short enough that the boat can fit in the second cave stop and the beach later.

The Green Caves offer a different kind of setting. The attraction here is not only the color but the underwater passages. If you are comfortable in the water, you may swim through or beneath parts of the cave area, depending on the conditions and the skipper’s instructions. There are also spots for jumping from the rocks, but this is optional. You should never jump until the guide confirms that the water depth and route are safe.

The water is a major part of the experience. Several accounts describe excellent visibility and enjoyable snorkeling, while another noted that the fish life was not especially varied. That is a useful distinction. Come for the clear water, rock formations, and sense of being in the sea, not for a full reef expedition.

Swimming gear, drinks, and practical comfort

Snorkeling equipment is listed as included, and many departures provide masks and gear for use in the water. However, equipment feedback has not been completely consistent. One account reported receiving masks but no snorkels, while others specifically said snorkeling gear was provided.

That makes a simple question worthwhile before the boat leaves: ask the skipper to show you the available masks and snorkels. If you are particular about fit or hygiene, bringing your own mask and snorkel may be sensible. The tour is still enjoyable without extended snorkeling, but the caves are far more rewarding when you can see below the surface.

Bottled water, soda, and alcoholic drinks are included. The exact offering is not clearly defined, and one account described receiving only one alcoholic drink and no soft drinks. Treat the drinks as a pleasant extra rather than an open bar. Bring any specific beverage you need, especially if you have dietary or personal preferences.

Safety equipment deserves a similar check. One negative account raised concerns about life jackets and the lack of a clear safety briefing. This is a serious point for anyone who is not a confident swimmer. Ask where the life jackets are before departure and listen carefully to the skipper’s instructions around the caves and jumping areas.

The operator responded that the boat carries equipment, but the differing account is still useful to you. A good tour should make safety procedures clear without you having to ask. If you are traveling with children or feel uneasy in open water, raise the issue before boarding.

Ninety minutes at Sunj Beach on Lopud

After Kolocep, the boat heads to Lopud Island and its main draw, Sunj Beach. This is one of the few sandy beaches near Dubrovnik, and the change from rocky cave water to a broad sandy shore gives the afternoon a welcome pause.

You get about an hour and a half here. That is long enough to swim, sit on the sand, walk toward the beach bars, or head uphill to a small forest restaurant. The water is shallow and warm near the shore, with a gradual shift in color from green to blue. Families and less confident swimmers may appreciate the easy entry, though the beach can feel busy during the popular summer hours.

The beach stop is not a guided sightseeing walk. You are dropped off for free time, so you decide how to use it. Some people will head straight into the water. Others may prefer a drink, food, music, or a shaded seat above the beach. Accounts describe beach bars, good food, cocktails, and at times a DJ, but the atmosphere can vary by day.

Lunch is not included. If you want a meal, budget separately for the restaurant or beach bar. The 90-minute stop gives you an opportunity to eat, but do not assume that a full restaurant meal will fit comfortably if service is slow. For a relaxed visit, a swim and a drink may be the better plan.

This stop also helps explain the tour’s popularity. The caves provide the memorable natural sight, but Sunj gives you somewhere comfortable to dry off and slow down. You get a beach experience without arranging a separate ferry and taxi or committing to an entire day on Lopud.

The guides make a real difference

The skipper is not just driving the boat. On a good departure, this person sets the pace, explains the islands, recommends where to eat, and decides how to respond to sea conditions.

Maro has received especially warm praise for being engaging and flexible. Jakov, also spelled Yakob in one account, has been described as friendly and relaxed. Antun, also listed as Anton, has been appreciated for local knowledge and smooth boat handling. Paulo has also been singled out for a strong afternoon trip.

These names matter because the style can vary. One account found the guide quieter but still enjoyed the caves, water, and beach. If you want a running commentary, ask questions as you travel. If you prefer a calm outing with less talk, a quieter skipper may suit you well.

Sea conditions can affect the route. One departure encountered choppy water, and the skipper slowed down and kept an alternative plan in reserve in case the caves could not be reached. That is the right attitude for a water excursion. The caves are the goal, but safe boating has to come first.

Who should book this Dubrovnik excursion?

I would choose this trip if you want a short, active island outing rather than a formal sightseeing cruise. It suits couples, friends, and solo visitors who enjoy swimming and do not need a large amount of space.

It is also a good match if you have only one free half-day. The tour gives you cave scenery, open-water swimming, and a sandy beach in roughly four hours, leaving the rest of the day for Dubrovnik.

You should think twice if you dislike speedboats, get motion sick, or want guaranteed shade and room to stretch out. The boat may feel crowded at full capacity. This is also not the right choice if your main goal is serious snorkeling, since the marine life may be modest and the equipment arrangement can vary.

Families can enjoy the shallow water at Sunj, but parents should ask about life jackets and supervise children around the cave entrances and rock-jumping areas. Most people can participate, but you need to be comfortable getting in and out of the water.

The tour is accessible by public transportation, but hotel pickup and drop-off are not included. Allow time to reach Lapadska obala 4 and confirm the boat before departure.

Cancellation and weather notes

You can cancel for a full refund up to 24 hours before the start time. Changes made inside that window are not accepted, and late cancellations are not refunded.

The trip needs good weather. If poor conditions cancel the departure, you are offered another date or a full refund. The same applies if the minimum number of participants is not reached. That policy is useful, since cave access and speedboat travel depend heavily on the sea.

Should you book the Blue and Green Cave trip?

Book it if you want to combine Kolocep’s caves with a real beach break and you are happy with a compact speedboat. The strongest features are the two 30-minute-plus cave stops, the clear swimming water, the included drinks, and the generous time at Sunj Beach. The four-hour format also gives you a lot without taking over your day.

Before paying, contact the operator with two practical questions: How many people are expected on your boat, and exactly what snorkeling and safety equipment will be available? If the answers suit you, the $78.64 price is fair for a guided half-day on the Dubrovnik islands.
