The best part of this Dubrovnik outing is the quick run across the water to Kolocep, where several sea caves sit close together. You can approach the Blue Cave by boat, jump into the clear Adriatic, and move between the Blue Cave, Green Cave, and three smaller caves without spending half your day in transit.

I like the private boat setup, since your skipper can adjust the pace instead of pushing you through a fixed group schedule. I also like the practical extras: snorkeling gear, bottled water, soda, and a choice of morning or afternoon departure. The main consideration is food. Nothing to eat is included, and four hours can pass quickly if you want generous time at both the caves and Sunj Beach.

Key points to know before booking

Blue and Green Cave Tour from Dubrovnik,private speed boats - Key points to know before booking

  • Kolocep is only about 20 minutes away by speedboat, leaving more time for swimming and cave stops.
  • The Blue Cave is part of a small group of caves, including the Green Cave and three smaller openings nearby.
  • Your skipper controls the pace, with time arranged directly on the boat.
  • Sunj Beach on Lopud adds a sandy swimming stop, a welcome change from the rocky cave coast.
  • Two departure times are offered, usually around 9:30 in the morning or 2:00 in the afternoon.
  • The price is $438.51 per group of up to six, so the value improves sharply when the boat is full.

A fast crossing from Dubrovnik to Kolocep

You meet at Obala Stjepana Radića in Dubrovnik, then head out by private speedboat. The crossing to Kolocep takes about 20 minutes, which is one of the clearest advantages of this trip. You reach the islands quickly instead of spending much of a short outing on a slow ferry.

The boat is intended for a private party, not a mixed group. The supplied information gives the price for up to six people, while the general description mentions space for up to eight passengers. If your party has seven or eight people, confirm the exact capacity and price before paying.

The speedboat ride also gives you a pleasant first look at the Adriatic around Dubrovnik. The real purpose, though, is practical: the boat gets you to the cave coast fast and can move between stops with little fuss.

You can choose a morning departure around 9:30 or an afternoon departure around 2:00. The morning option gives you a longer-feeling day and may suit you if you want to keep the evening free. The afternoon option works well if you prefer a slower start or want to fit the boat trip around sightseeing in Dubrovnik.

The tour lasts about four hours. That is enough for the caves and Lopud, but it is not an all-day cruise unless you arrange an upgrade. If you want long swims, a leisurely beach stop, and extra time at several caves, ask about the full-day option before booking.

A few more Dubrovnik half-days to weigh up

The Blue Cave and Kolocep’s rocky coast

Blue and Green Cave Tour from Dubrovnik,private speed boats - The Blue Cave and Kolocep’s rocky coast

Kolocep’s cave area is the heart of the experience. The skipper takes you toward the rocky side of the island and tries to get as close to the Blue Cave as conditions allow. The exact approach depends on the sea and the boat’s position, so you should think of this as a flexible water outing rather than a guaranteed step-by-step cave visit.

The Blue Cave is the name most people will remember, but it is not the only stop. Nearby are the Green Cave and three smaller caves. Seeing several openings close together gives the outing more variety than a single photo stop.

You can jump from the boat, swim, and use the provided snorkeling equipment. That freedom matters. You are not simply looking at the coast from a seat. You get the chance to experience the caves from the water, where the rock walls and changing light become the main attraction.

The water is described as crystal clear, making swimming and snorkeling a central part of the trip. Still, you should be comfortable entering the sea from a boat. The information does not promise a dock, steps, or a shallow entry at every cave, so ask the skipper about the easiest way in if you have mobility concerns or prefer not to jump.

The skipper usually acts as both guide and safety lead. A good skipper will explain where to swim, help you judge the conditions, and keep the boat positioned as close to the cave as practical. Ado is one skipper specifically associated with this experience. The available feedback describes him as relaxed, helpful, and good at sharing information without filling every quiet moment with commentary.

That balance is important on a private boat. You can ask about the islands, then settle back and enjoy the ride. You can also tell the skipper if you want to stay longer at one spot or move on. The timing is not entirely rigid, which is useful if one cave or swimming area suits your group better than another.

Swimming between the Blue Cave and Green Cave

Blue and Green Cave Tour from Dubrovnik,private speed boats - Swimming between the Blue Cave and Green Cave

The cave section is best for people who enjoy active sightseeing. You may spend much of the time moving between boat and water, looking into cave entrances, and snorkeling near the rocky shoreline. Bring a swimsuit and wear something practical for getting in and out of the sea.

The provided equipment includes snorkeling gear, but you may want to confirm what is supplied if fit matters to you. Bottled water and soda are included, along with refreshing drinks such as beer, water, and juices according to the tour details. The inclusions are useful, but they do not replace a meal.

The private format makes the cave stops easier to enjoy as a group. You do not have to match the pace of strangers, and your skipper can offer choices. The feedback describes a morning outing with four different stops, which gives you a sense of how much variety may fit into the time, though the exact sequence depends on conditions and your preferences.

Do not expect the caves to feel like a formal attraction with paved paths, signs, or a visitor center. Their appeal comes from the natural setting and the simple act of reaching them by boat. If you want a polished sightseeing route with fixed explanations at every stop, this may feel informal. If you prefer time in the water and a less scripted pace, that informality is a strength.

The boat is also a good place to manage your energy. Not everyone in your group has to swim at every stop. Some can stay aboard while others enter the water, then everyone can regroup before moving to the next cave.

Lopud and the sandy stretch at Sunj Beach

Blue and Green Cave Tour from Dubrovnik,private speed boats - Lopud and the sandy stretch at Sunj Beach

After Kolocep, the boat continues to Lopud. The change of scene is welcome. The cave coast is rocky and focused on swimming, while Sunj is known as one of Croatia’s attractive sandy beaches.

A sandy beach gives you an easier place to relax after the cave stops. You can swim from shore, sit on the sand, and enjoy a slower pause before returning to Dubrovnik. For a group with mixed interests, this stop helps balance the active cave portion.

Sunj may be especially useful if someone in your party is less keen on snorkeling or jumping from a boat. They can still enjoy the island setting and swim from the beach. The information does not specify how long the boat remains at Sunj, so arrange the timing with the skipper rather than assuming a fixed beach stay.

This is also where the four-hour length becomes noticeable. You have a speedboat ride, several caves, and a beach stop to fit into a short window. I would tell the skipper early if Sunj is a priority, especially if your group also wants time at the Blue Cave and Green Cave.

The beach is not a meal stop in the tour price. Food is excluded, so bring money if you plan to buy something on your own, or eat before departure. Since only drinks are specifically included, do not count on lunch, snacks, or a packed meal from the operator.

What the private format is worth at $438.51

Blue and Green Cave Tour from Dubrovnik,private speed boats - What the private format is worth at $438.51

The listed price is $438.51 per group of up to six. At six people, that works out to about $73 per person. With four people, it is about $110 each, and with two people, the private format becomes a much more expensive choice.

That calculation is the key to judging the value. If you can fill the boat with family or friends, you are paying for speed, privacy, and control over the schedule. You are not just paying for transport to Kolocep. You are also getting a skipper, snorkeling equipment, bottled water, sodas, and access to a flexible route that covers caves and Lopud.

The price makes less sense if you are alone or as a couple and do not care about privacy. A shared boat could be cheaper, though no shared option is described here. The private boat is most attractive when your group values having the boat to yourselves and can split the cost.

The skipper’s role also adds value. Ado, specifically, is described as giving useful information while allowing quiet time. That is the right style for a short sea outing. You want enough guidance to understand where you are, but you also want time to swim without a running lecture.

The trip is recommended by all listed participants and has a rating of 5 from 34 reviews. That is a strong record, but you should still match the product to your habits. The high marks focus on the skipper, the boat, the scenery, several stops, and the ability to choose whether to stay longer or move along.

Choosing the morning or afternoon departure

Blue and Green Cave Tour from Dubrovnik,private speed boats - Choosing the morning or afternoon departure

The two usual start times are around 9:30 in the morning and 2:00 in the afternoon. Your choice will shape the feel of the trip more than the route itself.

Choose the morning if you want to make the boat trip the main event of your day. You will return with time left for Dubrovnik, though the exact return time depends on the outing’s pace. Morning also gives you more flexibility if you want to ask about extending the trip.

Choose the afternoon if you prefer to explore Dubrovnik first. The later start can be convenient for a relaxed holiday schedule, but remember that the outing is only about four hours. You will be spending part of the later day on the water, so this option may leave less time afterward for other plans.

The weather matters. This activity requires good conditions, and poor weather can lead to a new date or a full refund. The cancellation rule allows a full refund when you cancel at least 24 hours before the start time. Changes or cancellations inside that 24-hour window are not accepted for a refund, except when the operator cancels because of weather.

Who will enjoy this boat trip most

Blue and Green Cave Tour from Dubrovnik,private speed boats - Who will enjoy this boat trip most

I would recommend this outing to a small group that wants an active half-day on the sea rather than a passive sightseeing cruise. It suits friends, couples traveling together, and families who can share the cost and agree on a flexible pace.

It is a good match if you want:

  • A quick trip from Dubrovnik to nearby islands
  • Swimming and snorkeling in clear sea
  • Several cave stops instead of one short photo stop
  • A private boat and skipper
  • A sandy beach break at Sunj
  • Morning or afternoon scheduling

You should think twice if your main goal is a long beach day. Sunj is included as a stop, but the total experience lasts about four hours and also includes the caves and boat travel.

You should also consider your group’s comfort with water access. The activity centers on swimming from the boat and may involve jumping into the sea. Most participants can take part, and service animals are allowed, but the details do not promise a fully accessible boat or beach transfer.

Practical details for a smoother outing

Blue and Green Cave Tour from Dubrovnik,private speed boats - Practical details for a smoother outing

Meet at Obala Stjepana Radića, 20000 Dubrovnik. The activity returns to the same meeting point, so you do not need to arrange a separate ride back from Lopud or Kolocep.

Confirmation is normally sent at booking. If you book within one hour of departure, confirmation may take longer and depends on availability. I would avoid leaving this until the last minute, especially since the experience is often reserved well ahead of time, with bookings averaging about 55 days before the date.

Pack swimwear, sun protection, and a dry change of clothes. These are sensible items for any boat trip, though only the snorkeling equipment, bottled water, and soda are specifically supplied. Since food is not included, plan your meal before departure or ask the skipper what timing will work best for buying food independently.

Keep your schedule loose around the trip. The sea, cave access, and your group’s swimming time can affect the pace. A private outing gives you more control, but it does not remove the need to respect weather and safety conditions.

Should you book the Blue and Green Cave Tour?

Book it if you have a group of up to six, want a private speedboat, and value swimming time over a tightly scripted sightseeing route. The strongest reasons are the short ride to Kolocep, the cluster of Blue and Green Caves, the sandy stop at Sunj, and a skipper who can adjust the day to your group.

At full capacity, the $438.51 cost is reasonable for a private four-hour outing with equipment and drinks included. For a smaller group, the price per person rises quickly, so compare it with other boat options before committing.

I would choose the morning departure for the most flexible day, or the afternoon if you want to spend your earlier hours in Dubrovnik. Just remember that food is extra, cave access depends on conditions, and the trip is designed for people who are happy to swim from a boat. If those points suit you, this is a focused and enjoyable way to add the nearby islands to a Dubrovnik stay.
