Dubrovnik: Blue & Green Caves Private Boat Tour with Drinks

The best part of this Dubrovnik boat trip is the chance to swim into the Blue Cave, rather than simply photograph it from a boat. You also get the quieter Green Caves, cliff-jumping opportunities, and a stop at Sunj Beach, the area’s rare sandy beach.

I like the small private-boat setting and the open drinks policy, which includes beer, local rakia, water, and juice. Guides such as Mario, Duje, Robert, and Drago have earned praise for helping people through tight cave passages and keeping the mood relaxed. The main catch is that cave conditions and crowds vary, and the advertised cliff jump or GoPro may not always be available.

Key points to know before booking

• Blue Cave swimming: You enter from the sea, so swimming is part of the experience. Life jackets and flotation aids are available.
• Three cave areas: The route includes the Blue Cave, Green Cave, and Three Green Caves around Koločep Island.
• Private speedboat: You avoid a large tour boat and get a faster, more flexible ride along the Dubrovnik coast.
• Sunj Beach stop: You have about 90 minutes for swimming, relaxing, food, or a golf-cart outing on Lopud.
• Drinks included: Beer, local brandy, water, juices, and some other self-service drinks are available on board.
• GoPro provided: When available, the action camera lets you record the swims and cave passages without risking your own phone.

Why this four-hour boat trip works

Dubrovnik’s old town gets much of the attention, but the islands just offshore offer a different kind of day. From the water, you see the Franjo Tuđman Bridge, Grebeni Lighthouse, rocky coves, and the low wooded shores of the Elaphiti Islands.

This trip focuses on swimming rather than long historical talks. The guide drives the speedboat, explains how to approach the caves, and helps you judge the water and rock passages. The experience is active, but it is not a full-day expedition. Four hours gives you a good taste of the coast without taking over your entire day.

I especially like the mix of stops. The caves provide the excitement, the open-water ride gives you views and speed, and Sunj Beach supplies a slower finish. That balance makes the outing work for couples, families with older children, and groups of friends who want more than a sightseeing cruise.

The private format is important. You can sit around the boat, listen to music, stop for swims, and spend time with your own group rather than joining a crowded vessel. Some departures have included up to nine people, so confirm the exact boat and group arrangement if complete privacy is essential.

From Gruž to Koločep Island

The meeting point is on the pier just across from Gruž Market and the construction site. You do not get hotel pickup, so allow time to reach the pier on your own.

Once on board, the boat heads past the Franjo Tuđman Bridge. This opening stretch is mainly a scenic cruise, but it helps you see how quickly Dubrovnik changes from city waterfront to open coast.

The boat also passes Grebeni Lighthouse, a small offshore marker that makes a useful photo stop. Guides may point out scenic spots along the way, but the main attraction is the ride itself. A speedboat gives you a lively sense of the coast, though it can feel bumpy if the sea is choppy. Sit where you can hold on, especially if you are prone to motion sickness.

The boat is described as modern and comfortable, and several guides have been praised for careful handling around narrow cave entrances. That matters more here than raw speed. The captain needs to bring you close enough to the rocks while leaving room for swimmers and other boats.

Swimming into the Blue Cave

The Blue Cave on Koločep is the trip’s headline stop. You receive snorkeling equipment, then enter the cave from the water with the guide. Plan on roughly 50 minutes in this area, including swimming, photos, and time around the entrance.

Inside, the water and rock walls create the blue effect that gives the cave its name. The color can look much less intense than photographs suggest, especially when the cave is crowded or the light is poor. I would set your expectations at beautiful and atmospheric, not guaranteed social-media blue.

You need to be comfortable in the water. The route into the cave is not a dry walk, and some passages can feel tight or dark. Strong swimmers may find the entry straightforward, while beginners should use the life jackets or flotation aids available on the boat. Guides such as Robert and Mario have been praised for entering the water with the group and helping people through tricky sections.

Take your time getting back onto the boat. One useful practical complaint concerned the metal ladder, which can become slippery with wet feet. Hold the rails carefully and do not rush the climb.

The Blue Cave can also be busy, even on earlier departures. If you choose the 2 p.m. time slot, you may get warmer late-day light and a sunset-colored ride back, but you should not assume the cave itself will be quiet. The afternoon departure has been especially appealing to people who enjoy the changing light on the return journey.

The Green Cave and Three Green Caves

The Green Cave section is often the more relaxed part of the cave visit. You cruise toward the rock formations, stop for photos, and spend time in the water. The itinerary allows about 30 minutes at one Green Cave area and about 45 minutes around the Three Green Caves.

These stops are less about one famous visual effect and more about moving through a series of natural openings and swimming spots. You might see sunlight slipping across the rocks, dark water beneath overhangs, and narrow passages that larger boats cannot approach as easily.

This is where a capable guide makes a real difference. Robert and Mario have been singled out for taking groups into tighter cave sections, while Duje has been praised for handling crowded water near the entrances. You should still follow the guide’s instructions. A cave may look easy from the boat but feel very different once you are swimming beside the rock.

Bring an underwater flashlight if you have one. Some cave sections are very dark, and the supplied GoPro is better for recording than for lighting your way. The GoPro is a useful bonus, but availability should not be the only reason you book. One visitor reported that the camera and cliff-jumping part were not provided on a particular outing, so treat both as subject to conditions and the crew’s decision.

Cliff jumping and open-water swimming

The tour advertises a chance to jump from a cliff. The exact spot and height can vary, and the activity may not happen on every departure. Never feel pressured to jump. The boat, cave swims, and snorkeling are still the core of the outing.

For confident swimmers, the water stops add a playful edge. You can jump from a suitable rock or boat area, swim around the coves, and use a pool noodle or other flotation aid if offered. The guide can help non-swimmers, but you still need to recognize that much of the tour takes place in open water.

If you are not a strong swimmer, tell the guide before entering a cave. Life jackets are available, and guides have helped people through the water, but this is not a dry sightseeing tour. Anyone with limited swimming ability should stay close to the boat and use the flotation equipment.

Sea conditions matter. On a calm day, the water can be clear and inviting. When the sea is rough, swimming may be harder and the speedboat ride less comfortable. The provider may adjust what you do for safety, so keep your schedule flexible and do not book this as a guaranteed cliff-jumping session.

Sunj Beach on Lopud

After Koločep, the boat heads to Lopud and Sunj Beach. This is the only sandy beach in the region, and its pale sand offers a welcome change from the usual rocky Croatian shoreline.

You get about an hour and a half here, although some people wish they had longer. Use the time for a swim, a drink, a meal, or a slow walk along the beach. The beach has bars where you can order food and cocktails, but food is not included in the tour price.

A useful local tip is to ask about a lounge chair and umbrella when buying a drink. Several people found that one purchase at the beach bar could provide access to a lounger, but bring cash because at least one beach bar accepts cash only.

You can also rent a golf cart to see more of Lopud. The island has a medieval monastery and a botanical garden, both described as free to enter. With only 90 minutes, you will need to choose between a long beach break and a quick island look. I would stay by the water unless you have already had plenty of swimming time and care more about seeing Lopud.

Sunj is a good final stop because it slows the pace. After the cave swims and fast boat ride, you can sit down, eat, and enjoy the warm water without needing to keep moving.

Drinks, music, and the feel on board

The free drinks are more generous than the usual single bottle of water. You can help yourself to beer, local rakia brandy, water, juices, and other listed self-service drinks. This is particularly useful on a hot day, when cave swimming and sun exposure can leave you thirsty.

Drink sensibly. Rakia and beer are easy to enjoy on a boat, but alcohol can affect balance and swimming ability. Hydrate with water before entering the caves, and save most of the drinking for the ride or the beach.

The boat atmosphere can be social without being forced. Some guides have let groups connect a phone to the sound system and choose music. Mario, in particular, has been praised for involving everyone, while other guides take a quieter approach and give you more space.

That difference may matter to you. If you want a lively skipper who joins the fun, ask about guide availability when booking. If you prefer a calm ride, the private format still lets you settle into your own group.

Is $73 a good value?

At $73 per person, the tour offers strong value if you plan to use the swimming stops and the included drinks. You are paying for a private speedboat, an English-speaking guide, snorkeling equipment, a four-hour route, cave access by water, and time at Sunj Beach.

A separate boat hire would likely give you more control but would not necessarily include a guide who knows the cave entrances. A large group cruise might cost less, but you would give up much of the relaxed space and personal help in the water.

The value drops if you do not swim, skip alcohol and soft drinks, or mainly want a quiet beach day. In that case, a simple beach outing may suit you better. The tour is priced for an active coastal experience, not just transport between islands.

You should also budget for food, beach drinks, possible loungers, and a golf-cart rental if you choose to explore Lopud. None of those extras are included.

What to bring and who should book

Bring swimwear and a towel. Wear secure footwear if you have it, since wet boat ladders and rocky cave entrances can be awkward. Leave large bags and luggage behind, as they are not allowed on the boat.

I would book this if you want:

• Swimming in clear coastal water
• A faster, more private alternative to a large cruise boat
• Cave passages and snorkeling rather than only photo stops
• A social outing with drinks and music
• A beach stop that includes time to eat and relax

I would think twice if you dislike open water, have limited mobility around boat ladders, or want a guaranteed cliff jump and a perfectly blue cave. The staff can help non-swimmers, but the main attractions still require you to enter the water.

Cancellation is flexible up to 24 hours before departure for a full refund, and you can reserve now and pay later. Starting times vary, so check the available slot before planning the rest of your Dubrovnik day.

Should you book the Blue and Green Caves tour?

Book it if you want a lively half-day on the sea and you are happy to trade certainty for natural conditions. The Blue Cave may be crowded or less blue than expected, and the sea may limit cliff jumping, but the combination of Koločep’s caves, a modern speedboat, unlimited basic drinks, and Sunj Beach makes this a well-rounded outing.

The strongest version of the trip comes with a guide such as Mario, Duje, Robert, or Drago who gets in the water, explains the cave entry, and pays attention to nervous swimmers. Ask for snorkeling gear and flotation support, bring cash for the beach, and choose the afternoon slot if you like the idea of sunset light on the ride home.
