Dubrovnik: Blue Cave & Sunj Beach Boat Tour with Drinks

The best part of this Dubrovnik boat tour is the chance to swim into sea caves rather than simply view them from offshore. On Koločep, the Three Green Caves and Blue Cave offer clear water, echoing rock walls, and a quick taste of wild Adriatic scenery, followed by a long break at sandy Šunj Beach.

I like the generous 90 minutes at the beach, and I like that drinks and snorkeling equipment are included instead of treated as extras. Skippers such as Mark, Erik, Anthony, Dominic, and Roko also receive repeated praise for keeping the mood easy and helping people feel safe in the water.

The main consideration is that cave access depends on sea conditions. In rough weather, the boat may stop at alternate swimming and snorkeling spots, and this is not a good choice for non-swimmers, people prone to seasickness, or anyone needing step-free access.

Key points to know before booking

• Swim into Koločep’s caves: The Blue Cave and Three Green Caves are the central attraction, with around 30 minutes at each cave stop.
• Šunj Beach gets the longest break: You have about 1.5 hours for swimming, sun, food, or a walk on Lopud.
• Drinks are part of the fare: Water, white wine, beer, Coca-Cola, and Fanta are offered at the stops.
• The speedboat ride is part of the fun: Expect short, brisk transfers between Dubrovnik, Koločep, and Šunj Beach.
• Conditions can change the plan: Rough seas may make cave entry unsafe, so alternate swimming locations may be used.
• Plan for a wet half-day: Bring swimwear and a towel, leave large luggage behind, and use the toilet before check-in.

A four-hour escape from Dubrovnik

At $74 per person, this is priced as a midrange half-day outing rather than a bare-bones boat transfer. You are paying for a skipper and crew, speedboat transport, snorkeling equipment, drinks, and the chance to reach several swimming spots in one morning or afternoon.

The tour covers the Elaphiti Islands, a group of islands just beyond Dubrovnik. You will spend much of the time outside, moving between stops by boat, with short rides of roughly 10 to 20 minutes. That makes the day feel active without committing you to a full-day cruise.

I see the best value here in the combination. A beach trip alone would be easy to arrange, and a cave visit alone would be brief. This tour links the caves with a long sandy-beach stop, so you get swimming, scenery, and downtime in one booking.

It is a shared tour, not a private charter. Some departures have been described as small, including one group of eight participants plus a guide, but the exact group size can vary. If you want a quiet private outing or complete control over the schedule, this is not the right product.

Boarding at Dubrovnik’s bus station dock

The meeting point is at the dock beside the Dubrovnik bus station. If you choose the pickup option, hotel collection and return are available in the Dubrovnik city area, but you must contact the operator before departure to receive the exact pickup time.

That detail matters. Pickup times depend on where you are staying, and failing to confirm the time can mean missing the boat without a refund. If you are meeting at the dock, allow time to find the correct boat and contact the operator by phone, email, or WhatsApp if you have trouble.

The trip begins with a safety briefing from the skipper. A lifejacket can be provided on request, but the tour requires basic swimming ability. You should be able to enter the water, resurface, control your breathing, float, turn, and move to safety.

The speedboat is quick and open to the weather. One person advised sitting toward the back when the sea is rough, and that is sensible advice. The ride can be bumpy, especially for anyone prone to seasickness, so take the medical and comfort restrictions seriously.

Koločep’s Blue Cave and the question of conditions

The Blue Cave is the most dramatic stop on paper. You approach by boat, then enter the cave by swimming through clear water. Inside, the rock changes the light and sound, giving the stop a sheltered, enclosed feel that you cannot get from a normal beach swim.

You generally have about 30 minutes here for swimming, snorkeling, photographs, and looking for marine life. That is enough time to enjoy the place without turning the whole tour into one long water stop.

The cave is also the part most affected by weather and sea conditions. On several late-season departures, the Blue Cave and the Three Green Caves were considered unsafe to enter. The skippers moved the group to other attractive swimming and snorkeling areas instead.

That is not a small footnote. If entering the Blue Cave is your one essential goal, you should accept that nature has the final say. The operator’s strongest practical choice is to avoid forcing a cave entry when the water is rough, even if that means the advertised highlight changes.

Afternoon departures may offer better light inside the Blue Cave, according to one useful tip from the tour. Morning departures, on the other hand, can help you reach the caves and beach before the busiest period. I would choose based on your priority: lighting and later coastal views in the afternoon, or cooler temperatures and a head start in the morning.

Swimming through the Three Green Caves

The Three Green Caves give the tour its second major swimming stop. Their name refers to the green-toned light and water around the cave openings, though the exact effect will vary with sunshine, water clarity, and the time of day.

You will have another roughly 30-minute pause for swimming and snorkeling. The stop is less about checking off a single viewpoint and more about moving through the water, seeing the rock from inside, and listening to the waves echo around the cave walls.

Clear water is a recurring strength of this outing. Several departures included sightings of fish, and the supplied snorkeling equipment makes it easier to look below the surface without bringing your own mask and fins.

Still, this is not a guided scuba session or a technical cave adventure. You are swimming in natural openings with crew supervision and safety instructions. Follow the skipper’s directions, stay within your ability, and ask for a lifejacket if you need extra support. A flotation aid does not replace swimming skills.

The cave stops suit confident swimmers who want a short burst of adventure. If you would rather stay dry, or if you are uncomfortable swimming from a boat, the experience will feel limited. The beach stop offers more choice, but the caves are the reason to book this particular tour.

The long break at sandy Šunj Beach

Šunj Beach is the relaxed middle or final act of the trip, depending on the running order used that day. The published timing gives you about 1.5 hours here, far longer than at either cave.

That extra time changes the pace. You can swim without watching the clock every few minutes, sit in the sun, buy food or a drink, or take a short walk. The beach is described as sandy, which is a welcome change from the rocky shorelines common around the Adriatic.

The surrounding area also offers a botanical garden, a Franciscan monastery, and restaurants. One stop included time to wander on Lopud and find a bite to eat, so you may have more to do than simply claim a patch of sand.

Sunbeds can be available through the beach club, with purchase conditions attached. One practical detail is that the beach is the only location on this tour with toilets. Use the facilities before boarding and do not expect a restroom on the speedboat or at the cave stops.

I like the balance here. After two active swims, you get a proper pause rather than another rushed photo stop. If your group includes someone who prefers sunbathing to snorkeling, Šunj Beach gives that person a reason to enjoy the day too.

What the boat ride feels like

The speedboat connects the stops quickly, with listed transfers of about 10, 15, and 20 minutes. You will not spend hours crawling between islands, but you will get repeated views of the Dubrovnik coast and the Elaphiti Islands from the water.

The boat ride is not silent transport. Music, conversation, and the rush of the boat across the water are part of the atmosphere. Some skippers are playful and energetic, while others focus more on information and safety. The individual guide can shape the mood of the trip.

The crew names most often associated with strong service include Mark, Erik, Anthony, Dominic, Roko, Dino, Matko, James, and Frank. You cannot normally select a particular skipper, but the consistent praise for several members of the team points to a well-established operation rather than a one-person show.

The boat can feel lively when the sea is choppy. People who enjoy a fast ride may see that as a bonus. If you prefer a gentle, stable cruise, sit toward the rear and consider a different type of boat excursion if seasickness is a concern.

Drinks, snorkeling gear, and what to pack

The fare includes one drink at each stop, with water, white wine, beer, Coca-Cola, and Fanta listed among the choices. This is useful after saltwater swimming, and it saves you from carrying a large supply on a small boat.

Do not read the drink inclusion as a full bar service. The wording describes a drink at each stop, although some departures have had plenty of refills available. If you want a specific nonalcoholic option, ask the crew rather than assuming every choice will be stocked.

Snorkeling equipment is included. You should bring:

• Swimwear
• A towel
• Beachwear
• Sun protection
• A small personal bag

Large bags and luggage are not allowed. A dry change of clothes can be useful, but keep it compact and protected from spray. Towels are not supplied, so this is one item you should not forget.

The boat has no toilet, and facilities are available only at Šunj Beach. That makes the pre-departure toilet stop more than a minor convenience.

Pickup, timing, and cancellation details

The tour lasts four hours, but the exact departure time depends on availability and the option you choose. You can book with or without hotel pickup. For pickup, contact the operator in advance and get the precise time for your accommodation.

The meeting point is beside Dubrovnik’s bus station, which is useful if you are arriving by public bus. One departure was reached that way without trouble, and the boat arrived on time. Even so, give yourself a margin because the tour will not wait for a late flight, cruise ship, bus, taxi, or wrong booking date.

Free cancellation is available up to 24 hours before departure, and reserve-now-pay-later booking is offered. Missed tours caused by late or delayed transport are not refundable. A medical refund requires a certificate from a doctor employed by a registered medical clinic.

These rules are strict but clear. I would avoid booking this on a day when your arrival connection is tight. A half-day activity works best when you have already settled into Dubrovnik.

Who should book this boat tour

This tour fits you well if you want:

• A short active outing from Dubrovnik
• Swimming and snorkeling in natural caves
• A sandy beach rather than only rocky swimming areas
• A social shared boat rather than a private charter
• Included drinks and equipment
• Hotel pickup as an optional convenience
• A mix of fast boat rides and unstructured beach time

It is especially good for couples, friends, and families with strong swimmers who want several highlights without spending a full day at sea. The 90-minute beach break also makes it more forgiving than a tour built entirely around rapid cave stops.

Think twice if you have back problems, reduced mobility, or a wheelchair. The experience requires boarding a speedboat and entering the sea for the cave swims. It is also listed as unsuitable for people over 70, people prone to seasickness, and non-swimmers.

The overall score is 4.8 out of 5 from 2,206 ratings, with guide service, safety, clear water, and the timing at each stop receiving especially strong praise. That matches the practical shape of the trip: the crew helps keep things moving, but you still get enough time to enjoy each place.

Should you book the Blue Cave and Šunj Beach tour?

Book it if you want a compact, active taste of the Elaphiti Islands and you are comfortable swimming from a boat. The strongest reasons are the two cave stops, the long pause at sandy Šunj Beach, included drinks, and the chance to let a skipper handle the route.

Do not book it solely on the promise of entering the Blue Cave. Sea conditions can close the caves, and the tour may shift to alternate swimming spots. If you can treat the caves as the highlight rather than a guarantee, the $74 price offers good value for a lively four-hour escape from Dubrovnik.
