Dubrovnik: Blue Cave & Sunj Beach Boat Tour with Drinks

The best part of this four-hour trip is the chance to swim inside sea caves rather than simply admire them from a boat. The Blue Cave and Three Green Caves on Koločep Island give you clear water, echoing rock walls, and a short, lively ride across the Adriatic. Then you get a proper stretch of sand and sun at Šunj Beach.

I like the small-group feel, which lets the skipper spend time helping people in the water instead of rushing everyone through. I also like the practical extras: drinks at each stop, snorkeling equipment, and optional pickup around Dubrovnik. The main catch is simple: this is an active boat trip, not a sightseeing cruise, and rough seas may close the caves or make the ride bumpy.

Key points to know before booking

• Three swim stops: You visit the Blue Cave, the Three Green Caves, and Šunj Beach, with time in the water rather than quick photo stops.
• Four hours on a speedboat: Expect a lively ride, spray, and some bumps if the sea is choppy.
• Drinks are included: Water, white wine, beer, Coca-Cola, and Fanta are offered at the stops.
• Guides make a difference: Mark, Erik, Anthony, Dominic, Roko, Dino, and other English-speaking skippers have been praised for safety, humor, and local explanations.
• Šunj gets the longest stop: You have about 90 minutes for swimming, sun, a walk, or a drink at the beach.
• Swimming ability is essential: A lifejacket can be provided, but it does not replace the ability to swim and manage yourself in the water.

A fast boat ride from Dubrovnik to the Elaphiti Islands

You meet the crew at the dock beside Dubrovnik’s bus station, unless you choose hotel pickup in the Dubrovnik city area. If you select pickup, contact the operator before the trip to confirm your exact time. That detail matters. Pickup times depend on where you stay, and missing the boat because you did not confirm the arrangements does not qualify for a refund.

After a safety briefing, you board the speedboat and head toward the Elaphiti Islands. The first ride takes about 15 minutes, so you reach the swimming stops quickly instead of spending most of the half-day in transit.

This is a shared tour, not a private charter. The exact group size can vary, but one reported outing had eight participants plus the guide, which gives you a useful idea of the scale. The boat ride is part of the fun, though it is not especially gentle. If you are prone to seasickness, have back problems, or dislike fast boats, this may not be your best Dubrovnik excursion.

Sit toward the back if the sea is rough. That position may give you a more comfortable ride, while the front can feel more exposed to bumps and spray. Bring only what you need because large bags and luggage are not allowed.

Blue Cave on Koločep Island

The Blue Cave is usually the first water stop. You get around 30 minutes for swimming, snorkeling, photos, and a drink. Light entering the cave gives the water its blue glow, though the effect changes with daylight, sea conditions, and the position of the boat.

The experience is more physical than a standard cave visit. You swim toward and through the cave, listen to the waves against the rock, and look back toward the bright opening. Crystal-clear water is a major part of the appeal, and you may see fish while snorkeling.

Your guide explains how to approach the cave and helps keep the group together. Guides such as Erik, Mark, Dominic, Anthony, and Roko have been singled out for making people feel safe and comfortable in the water. That support is useful if you are a confident swimmer but have never entered a sea cave before.

Conditions can change. Several outings in October had to skip entry into the Blue Cave or the green caves because the water was too rough. In those cases, the skipper took the group to other swimming and snorkeling spots. That is a fair safety decision, but you should not book this trip expecting guaranteed access to every cave.

The included drink is a nice touch after swimming. You can choose from water, white wine, beer, Coca-Cola, and Fanta. If you prefer a non-alcoholic option, water and soft drinks are available.

The Three Green Caves and clear Adriatic water

A short speedboat ride of about 10 minutes brings you to the Three Green Caves. You get another 30-minute stop for swimming, snorkeling, photos, and free time. The caves are linked by open water and rock passages, so this stop feels a little more exploratory than a single viewpoint.

The water is the star here. In good conditions, it is clear enough to see fish and the rock beneath you. The caves also provide shade and a cool break from the sun, though the water can feel cold outside the hottest summer months.

You need basic swimming skills. That means entering the water, resurfacing, controlling your breathing, floating, turning, and moving to safety. A personal flotation device can be supplied on request, but it is not intended to replace swimming ability.

This is where a guide’s judgment matters. A skipper such as Dino may show non-swimmers the area from the boat, but the official conditions are clear: non-swimmers are not suitable for this activity. If you are uncertain in open water, choose a boat trip without cave swimming instead.

The short stop also means you should be ready when the boat arrives. Keep your mask, swimsuit, towel, and any waterproof camera easy to reach. An underwater camera or GoPro is especially useful here, since ordinary phone photography is awkward from the water.

Ninety minutes at Šunj Beach

Šunj Beach on Lopud Island receives the longest stop, about 90 minutes. This is a welcome change of pace after the caves and boat rides. You can swim in shallow water, dry off in the sun, walk around, or find something to eat and drink.

The beach is sandy, which is unusual enough on the rocky Dalmatian coast to make it a popular stop. You may also have time to see parts of the surrounding area, including a botanical garden and Franciscan Monastery, though the exact amount of free time depends on the day’s timing and sea conditions.

Beach facilities are more practical here than at the caves. Toilets are available at the sandy beach, but not at the earlier swimming stops, so use the bathroom before check-in and plan accordingly.

Sunbeds may be available, but access can depend on purchasing food or a drink. Do not assume a lounger is included in the tour price. The same applies to meals and towels: neither is included.

The 90-minute stop works well because you are not forced to leave the beach after a quick swim. You have enough time to relax, and the stop gives non-swimmers a more comfortable part of the day. Still, the tour is built around swimming, so people who want a full beach day should book a dedicated beach outing instead.

Drinks, snorkeling gear, and what the price covers

At $74 per person, this sits in the middle range for a half-day Dubrovnik boat excursion. The value depends on how much you use the included features. You are paying for the speedboat, skipper and crew, three major stops, snorkeling equipment, drinks at each stop, and a four-hour route through the Elaphiti Islands.

Optional hotel pickup adds convenience if you are staying away from the bus station. If you can easily reach the meeting dock, you may prefer to meet the boat there and keep the arrangements simpler. Either way, confirm the location and time before departure.

Snorkeling equipment is included, which saves you from carrying your own mask and fins. Towels are not included. Bring one, along with swimwear, beachwear, sunscreen, and a dry layer for the ride back. Even in warm weather, you may feel cool after swimming or when the speedboat is moving.

The drink policy deserves a small clarification. The tour includes one drink at each stop, with water, white wine, beer, Coca-Cola, or Fanta listed as the options. Some customers describe frequent refills, but you should treat the formal inclusion as one drink per stop rather than unlimited alcohol.

The skipper can shape the whole outing

The route is attractive, but the skipper sets the mood and controls the pace. Mark has been praised for humor, music, local information, and keeping the boat lively. Erik is noted for safety and conversation. Anthony has been described as attentive, good with names, and able to speak several languages. Dominic, Roko, Dino, Matko, and other crew members have also received strong praise for friendliness and care.

You cannot normally request a particular guide or guarantee a specific skipper. The useful lesson is to expect a social, informal outing rather than a formal historical tour. The guides explain the caves and area, but the strongest part of their job is practical: choosing safe conditions, helping swimmers, and keeping the group moving.

Some guides may offer a relaxed atmosphere with music and jokes. That will suit you if you want an easygoing half-day on the water. If you prefer quiet nature watching or a detailed lecture about Dalmatian history, this may feel too casual.

The crew also adjusts the route when conditions require it. That flexibility is valuable. A safe alternate snorkeling stop is better than forcing a boat into a cave entrance during rough water, even if the original plan sounds more exciting.

Timing, weather, and the best time to go

Morning departures can help you reach the caves and beach before the busiest period. One useful tip is to choose an early tour if you want cooler temperatures and a better chance of arriving ahead of crowds.

Afternoon departures have a different advantage. The Blue Cave can look more intensely blue later in the day, depending on the sun’s position. If the cave effect is your top priority, an afternoon departure may be worth considering.

The season also changes the character of the outing. September can bring warm weather and clear water with less summer heat. October trips may still offer excellent swimming, but you will want a sweater for the ride after getting wet. Sea conditions are more important than the calendar, and cave access can be restricted when the water is rough.

The boat returns to Dubrovnik after the Šunj stop, with about 20 minutes on the water. Allow a little flexibility afterward if you have an important dinner, bus, or activity. Delayed flights, cruise ships, buses, taxis, or a wrong booking date are not grounds for a refund if you miss the tour.

Who should book this Dubrovnik boat tour?

This trip suits you if you want several experiences packed into one half-day: a speedboat ride, two cave visits, snorkeling, drinks, and a sandy beach. It works especially well for couples, friends, and families with older children who are comfortable in open water.

You will get the most from it if you can swim confidently, enjoy a lively crew, and do not mind a bumpy ride. The included gear and optional pickup make it easy to arrange, while the 90-minute beach stop prevents the tour from feeling like one continuous rush.

I would think twice if you have limited mobility, serious back problems, seasickness, or are over 70. The activity is also unsuitable for wheelchair users and non-swimmers. There are no toilets at the cave stops, and the boat does not accept large bags.

The cancellation policy is reasonably flexible: you can cancel up to 24 hours ahead for a full refund, and reserve now while paying later. Illness refunds require a medical certificate from a doctor employed by a registered medical clinic.

Should you book the Blue Cave and Šunj Beach tour?

Book it if you want an active, compact introduction to Dubrovnik’s nearby islands and like the idea of swimming through caves rather than viewing them from shore. The strongest reasons are the clear water, generous beach stop, included drinks and gear, and the crew’s clear focus on safety and fun.

Skip it if you need guaranteed cave access, dislike speedboats, or want a quiet boat ride with no swimming requirement. Weather can change the route, and the caves may be replaced by alternate snorkeling spots.

For most capable swimmers, $74 is a fair price for the four-hour combination. Choose the morning for cooler conditions and an early start, or the afternoon for a potentially stronger Blue Cave glow. Bring a towel, pack light, confirm your pickup, and be ready to get wet.
