Dubrovnik: Blue Cave & Sunj Beach Boat Tour with Drinks

The Adriatic saves its best color for caves. This four-hour speedboat trip links Koločep Island’s Blue Cave and Three Green Caves with a long stop at sandy Šunj Beach, making it a good way to see several coastal highlights without giving up an entire day. I especially like the included drinks and snorkeling gear, plus the lively, personal service from guides such as Mark, Erik, Anthony, Roko, and Dominic.

I also like the balance between active swimming and idle beach time. You can enter the caves, look for fish in the clear water, then spend about 90 minutes at Šunj. The main consideration is simple: you must be able to swim, and rough seas can make the speedboat ride bumpy or close the caves for safety.

Key things to know before booking

• Three cave stops make this more than a beach outing: You swim through the Three Green Caves and visit the Blue Cave around Koločep Island.
• Šunj gives you a proper break: You get about 1.5 hours for swimming, sun, food, drinks, or a walk near the beach.
• The ride is fast and open to the sea: The speedboat covers the route quickly, but people prone to seasickness should think twice.
• Drinks are included at each stop: Water, white wine, beer, Coca-Cola, and Fanta are listed, with one drink included at each stop.
• Morning timing can help: A morning departure may reach the caves and beach before the busiest period.
• The route depends on conditions: The Blue Cave or Three Green Caves may be too rough to enter, with alternate swimming spots used instead.

A four-hour escape from Dubrovnik

At $74 per person, this tour sits in the reasonable middle range for a half-day boat trip from Dubrovnik. You are paying for the speedboat, skipper and crew, snorkeling equipment, drinks at the stops, and possibly hotel pickup and drop-off if you choose that option.

The value comes from the variety. A slower boat trip might spend much of the day getting from one island to another. Here, the speedboat links several stops in roughly four hours, leaving you with cave swimming, open-water views, and a sandy beach in one outing.

This is a shared tour, not a private charter. The group size can be small, with one passenger describing a boat carrying eight participants plus the guide. That makes the trip more social and usually gives the skipper enough time to help people in the water. It also means you cannot set the whole schedule yourself.

The listed rating is 4.8 from 2,206 ratings, and the most consistent praise goes to the guides. Mark is often described as funny and relaxed, while Erik receives credit for keeping swimmers comfortable and safe. Anthony, Roko, Dominic, Dino, and Matko also receive strong praise for their friendly manner, practical help, and local explanations.

Setting out by speedboat

You meet at the dock beside Dubrovnik’s bus station unless you have arranged a pickup from a hotel in the Dubrovnik city area. If you choose pickup, contact the operator before the tour for the exact time. This matters because the pickup time depends on where you are staying, and missing the arranged pickup without contacting the operator means no refund.

The boat ride to the first stop is short, about 15 minutes in the published schedule. The speedboat is part of the fun, with quick runs between the islands and plenty of coastal scenery along the way. It is not a quiet sightseeing cruise, though. If the sea is choppy, expect some bouncing. One useful tip from the experience reports is to sit toward the back of the boat in rougher water.

You receive a safety briefing from the skipper before departure. A lifejacket can be provided on request, but the tour is clear about its swimming requirement. You need to know how to enter the water, resurface, control your breathing, float, turn, and move to safety. A flotation vest helps keep you afloat, but it does not replace swimming ability.

Bring swimwear, beachwear, and a towel. Towels are not supplied, and large bags or luggage are not allowed on board. Pack light, ideally with only the items you need for the water and beach.

Swimming into Koločep’s Blue Cave

The Blue Cave is the most dramatic stop on the route. Its appeal comes from the light inside the cave and the clear water around the entrance. You enter from the sea, so the experience feels more active than simply looking into a cave from a boat.

The planned stop lasts about 30 minutes. That gives you time for a swim, photographs, snorkeling, and a drink, though the exact amount of water time depends on sea conditions and the group. You may also see small fish in the clear water.

The color and visibility depend on the day and the light. One person who visited in the afternoon felt that later timing helped create a stronger blue-cave effect, while morning departures are praised for reaching the stops before crowds. That gives you a practical choice: choose morning for a quieter start, or consider afternoon light if the cave color is your top priority.

Do not treat the Blue Cave as guaranteed. In October, several outings could not enter the Blue Cave or Three Green Caves because conditions were unsafe. The guides used other places to swim and snorkel instead. That is a real limitation if the cave is the main reason you are booking, but it also shows why the skipper must make the final call.

The best guides handle this well. Erik is praised for explaining the cave, playing music, offering drinks, and helping people feel secure in the water. Dino is credited with helping non-swimmers enjoy the boat and surrounding views, though non-swimmers are still not suitable for this activity according to the tour rules.

The Three Green Caves near Koločep

The Three Green Caves provide a different feel from the Blue Cave. Instead of focusing on one glowing chamber, you swim through a group of natural openings and passages. The stop is listed at about 30 minutes, with time for swimming, snorkeling, photographs, and looking for marine life.

The water is the star here. Multiple reports describe it as exceptionally clear, with fish visible while snorkeling. You can bring an underwater camera or GoPro if you have one. The caves are far more memorable from water level than from a seat on the boat, but remember that you need to be comfortable moving through open water.

The skipper will explain how to approach the caves and where to swim. That guidance matters because the openings can feel less straightforward than a normal beach swim. Stay close enough to hear instructions, especially if the water is moving or the boat is waiting outside.

The order of the stops may vary. The tour description presents Šunj as an early stop, while the timed route places the Blue Cave and Three Green Caves before the beach. Departure time, sea conditions, and the skipper’s judgment can affect the sequence. The important point is that the tour is built around all three locations, not a rigid sightseeing timetable.

A long, useful stop at Šunj Beach

Šunj Beach is the relaxing part of the outing. You get about 1.5 hours here, much longer than at either cave. That gives you enough time to swim, dry off, have a drink or a meal, and slow down after the speedboat and cave stops.

The beach is known for its sand, which is a welcome change from the rocky shore found at many Adriatic swimming spots. You might also find time for a walk, and the area is described with a botanical garden, a Franciscan monastery, and restaurants nearby.

This stop is not just filler between caves. It makes the tour easier to enjoy because you are not rushing from one swim to the next. Several accounts call the beach club or loungers a highlight. Keep in mind that loungers may require buying food or a drink, so bring some spending money if you want more than the included refreshments.

Šunj is also the only place on the route with toilets. Use a restroom before boarding because there are no facilities at the cave stops. This is a small detail, but it matters on a four-hour boat trip.

Drinks, snorkeling gear, and the guide service

The tour includes snorkeling equipment, which saves you from bringing your own mask and snorkel. If you prefer your own gear, you can use it, but the supplied equipment makes the trip easier for casual swimmers.

A drink is included at each stop. The listed choices are water, white wine, beer, Coca-Cola, and Fanta. Some people particularly appreciate having a cold drink after swimming, but you should not assume that every beverage is unlimited. The formal inclusion is one drink at each stop.

The guide can make or break a short boat excursion, and this is where the trip receives its strongest praise. Mark is described as entertaining and relaxed, even letting one passenger take the controls briefly. Erik is praised for safety and conversation. Anthony is noted for remembering names and helping create a friendly atmosphere, while Roko receives praise for being attentive and explaining the area.

Other highly rated guides include Dominic, Dino, Matko, James, and Frank. The exact skipper depends on the departure, so you cannot book a particular person based on these names. Still, the repeated pattern is useful: the crew is a major part of the value, not just the transport between stops.

Timing, weather, and comfort

The tour operates for four hours, with departure times available according to the date. A morning trip may help you beat heat and crowds. An afternoon trip may offer better light inside the Blue Cave. If your schedule allows either option, choose based on your priorities.

Water temperature can matter outside the hottest summer weeks. People who went in late October found the water enjoyable but recommended carrying a sweater for the ride after swimming. The boat is exposed, so a dry cover-up is useful even on a sunny day.

Weather can change the plan. Rough water may make the ride uncomfortable, and cave entry can be closed for safety. The tour is not suitable for people prone to seasickness, people with back problems, people with mobility impairments, wheelchair users, people over 70, or non-swimmers.

That list is not a minor footnote. Boarding a speedboat, moving around a beach, and swimming from the boat all require physical ease. If you have doubts, ask the operator about a lifejacket before departure and be honest about your swimming ability.

Who will get the most from this tour

I would choose this trip if you want a lively half-day on the water rather than a long historical tour. It suits couples, friends, and families with older children who can swim and who enjoy a mix of excitement and downtime.

It is especially useful during a short Dubrovnik stay. In four hours, you see parts of the Elaphiti Islands that would be difficult to reach independently, and you still have most of the day left for Dubrovnik.

You will get the most from it if you are happy with a shared boat, limited luggage, and a schedule shaped by the sea. You should skip it if you want a private, quiet cruise, dislike fast boats, cannot swim, or need guaranteed access to the Blue Cave.

Practical booking advice

Choose hotel pickup only if you want the convenience and are staying within the Dubrovnik city area. Otherwise, the dock beside the bus station is the meeting point. Contact the operator by email, phone, or WhatsApp if you need help locating the boat or confirming your time.

The activity offers free cancellation up to 24 hours before departure and a reserve-now, pay-later option. The exceptions matter: no refund is given for missing the tour because of a delayed flight, cruise ship, bus, or taxi, booking the wrong date, or failing to show up at the pickup point. Illness refunds require a medical certificate from a doctor employed by a registered medical clinic.

Do not bring suitcases or large beach bags. Carry your swimwear, towel, beach cover-up, sunscreen, and only the essentials you can keep secure on a shared speedboat.

Should you book the Blue Cave and Šunj tour?

Book it if you want a compact mix of cave swimming, snorkeling, speedboat scenery, and beach time for $74. The included equipment, drinks, crew, and optional transfer make the price fair, especially when you value seeing several places in one morning or afternoon.

Go in with realistic expectations. The caves are weather-dependent, the boat can be bumpy, and this is an active swimming trip rather than a passive cruise. If you can swim, pack light, and accept that the skipper may change the route for safety, this is one of the more efficient ways to spend half a day around Dubrovnik.
