Dubrovnik: Blue Cave, Green Cave & Sunj Beach Speedboat Tour

The best part of this Dubrovnik boat trip is the chance to swim into the Blue Cave, rather than simply look at it from a boat. Sunlight filters through the water and lights the cave in a cool blue glow, while the nearby Green Caves offer clearer water, fish, and room to snorkel.

I like the small-group feel and the smart early departure, which can get you to the caves before the main rush. I also like the mix of activity and downtime: two swimming stops, then 100 minutes at sandy Sunj Beach. The main drawback is simple: this is a water-based outing, so non-swimmers and anyone uncomfortable entering caves should choose another excursion.

Key points

• Blue Cave swimming: Enter the cave by water and see sunlight reflected through the sea.
• Three Green Caves: Snorkel in clear water around Koločep, with time to swim or stay aboard.
• Early starts matter: Guides such as Toni, Antonio, Dominic, and Luka often leave promptly to beat the crowds.
• Sunj Beach stop: Enjoy 100 minutes on Lopud’s sandy beach, with bars and food nearby.
• Speedboat travel: The boat rides are quick, breezy, and part of the fun, but can feel lively on choppy water.
• Useful inclusions: Life jackets, snorkeling equipment, water, beer, wine, and music are included. Food is not.

Why the Caves Make This Dubrovnik Trip Worthwhile

Dubrovnik’s old city is beautiful, but it can also keep you focused on stone walls, polished streets, and busy viewpoints. This speedboat trip gives you a very different morning or afternoon, with open Adriatic water, low green islands, sea caves, and a sandy beach.

The main appeal is not sightseeing from a distance. You get into the water. At the Blue Cave on Koločep, the boat stops for about 40 minutes, giving you time for photographs, swimming, and snorkeling. The cave is shaped by natural openings and the way sunlight reaches the water, creating the blue effect that gives it its name.

The Blue Cave is best for confident swimmers. You need to leave the boat and make your way through the water, often in a confined space. A life vest is available, and the skipper gives instructions, but this is not a dry sightseeing cruise.

The tour then moves to the Three Green Caves, also on Koločep. This stop lasts about 40 minutes and gives you another chance to swim and snorkel. The water is clear enough to see below the surface, and guides may point out fish or use food to bring them closer to the boat.

I like the way these two stops complement each other. The Blue Cave is the visual highlight, while the Green Caves are better suited to relaxed swimming and looking underwater. If you enjoy being active in the sea, the two stops give you enough variety without filling the whole day with cave visits.

The Speedboat Ride From Dubrovnik

The listed meeting point is at Lapadska obala 4, though the exact point can depend on the option you book. You meet your guide at the pier, receive a safety briefing, and board the speedboat.

The first ride takes about 20 minutes. Later boat transfers take about 10 minutes between the cave stops, followed by roughly 30 minutes back to Dubrovnik after Sunj Beach. Those rides are not just transport. You get open views of the coast and a fast run across the water, with music playing and drinks available.

A speedboat lets the group reach places faster than a slower excursion boat. That matters here because the caves are more enjoyable before several other boats arrive. Several guides have made a point of leaving promptly, and the early morning departure is especially useful for quieter cave visits.

The tradeoff is comfort. A speedboat can bounce over waves, and the wind is strong when you are moving. Keep your belongings secure, and do not bring oversize luggage. Wear swimwear under your clothes, pack a towel, and protect any phone or camera you take near the water.

The experience is available as a private or small-group outing. Group size can vary, but the trip is designed to keep the boat social rather than crowded. Some departures have used two boats for a larger booking, while other groups have had about 10 people on one boat. If having plenty of space matters to you, check the group option before paying.

Entering the Blue Cave at Koločep

The Blue Cave is the first major stop, and it is the reason many people book this outing. After the boat reaches Koločep, you receive guidance on the safest way to enter and exit. The actual experience is simple but striking: swim toward the cave opening, pass inside, and look back at the water glowing blue.

The color comes from sunlight passing through the sea and reflecting off the sandy bottom. It changes with the light and conditions, so the cave may look different from one departure to another. An early visit can offer attractive light as well as fewer boats.

This is also where you should be honest about your swimming ability. The activity is not suitable for non-swimmers, and the operator does not accept children under two or people over 95. A less confident swimmer can request a life vest, but you still need to feel comfortable entering the water and moving through a cave.

Your guide can help with the practical details. Toni, Antonio, Dominic, Dominik, Luka, and Luca are among the guides who have led this route, and guests have particularly appreciated clear instructions around the cave entrances. The exact guide depends on the departure, so do not book expecting a specific person.

Bring a waterproof phone case or a camera designed for water if you want photographs. One person had a phone damaged by water, which is a useful warning. The cave is a place to enjoy first and photograph second.

Snorkeling the Three Green Caves

After about 10 minutes on the boat, you reach the Three Green Caves. The stop lasts around 40 minutes, with time for swimming, snorkeling, photos, and a drink.

The Green Caves feel less focused on one dramatic visual effect. Their appeal is the clear emerald-toned water, narrow spaces, and underwater views. You can use the provided mask and snorkeling equipment to look for fish and see the rocky formations below.

Snorkeling gear is included, though one person noted that the mask and snorkel were not always handed out together. If you want to get into the water quickly, check that you have the full set before the boat pulls away from the stop.

The water may feel cold on an early morning departure, especially outside the hottest summer weeks. That is not a flaw in the tour, but it is worth planning for. A towel and warm layer for the boat ride back will make the day more comfortable.

You do not have to spend every minute in the water. You can sit on the boat, listen to music, have water or a drink, and watch others snorkel. That flexibility helps if your group includes mixed swimming abilities, though everyone should be comfortable around open water.

One Hundred Minutes at Sunj Beach

The final stop is Sunj Beach on Lopud, reached after another short speedboat ride. You get about 100 minutes here, which is enough for a swim, a walk, lunch, or a slow drink at a beach bar.

Sunj is a welcome change after the caves. The beach is sandy, and the setting is more traditional for a summer afternoon. You can lie in the sun, swim in shallow water, or walk toward the bars and restaurants near the beach.

Food is not included in the tour, but you can buy lunch, street food, barbecue dishes, regional food, and drinks at the stop. Some guides recommend a particular hillside restaurant or a bar in the woods, but you are free to choose how to use your time.

There is one practical cost to remember. Beach beds may be available with a drink purchase, and one booking noted a €5 drink requirement for free beds. That is not part of the $73 tour price, so bring room in your budget for lunch, drinks, or a lounger.

The 100-minute visit is a good length for a half-day trip, though some people would prefer another 30 to 45 minutes. If your main goal is a long beach day, this tour may feel too busy. If you want caves first and a beach finish second, the timing works well.

Drinks, Music, and the Small-Group Mood

The boat includes water, beer, white wine, and music. That changes the feel of the trip from a strict sightseeing transfer into a relaxed outing with a social edge.

The guides are a big part of that atmosphere. Toni is often described as friendly and fun, Antonio as energetic and welcoming, Dominic and Dominik as safe and entertaining skippers, and Luka or Luca as guides who keep the group involved and offer useful tips. The tone can be lively, with music and jokes, but the core of the trip remains practical safety instruction and organized timing.

This is a good choice if you want to meet a few people without committing to a full-day group cruise. Couples, friends, families with older children, and solo visitors can all fit the format. A nine-year-old enjoyed the trip, but the cold morning water and cave swimming may not suit every child.

The social atmosphere is less suitable if you want silence, privacy, or a formal guided tour. For that, a private option is the better fit. A private boat may also help if your group wants to spend more time snorkeling and less time at the beach, though the exact arrangement depends on the booking.

Is $73 a Fair Price?

At $73 per person, the value comes from combining several separate outings into one half-day route. You get speedboat transport from Dubrovnik, two cave stops, snorkeling equipment, a life jacket, water, beer, wine, music, and time at Sunj Beach.

You still need to pay for food and anything you buy on Lopud. Hotel pickup and drop-off are not included, so you must reach the pier yourself. Those extra costs are small compared with a full-day island excursion, but they should be part of your calculation.

I see the price as fair if you want an active coastal trip without giving up an entire day. The boat covers several island stops quickly, and the early departure can improve the cave experience by reducing crowding. The value is weaker if you do not swim, prefer a quiet cruise, or mainly want to sit on a beach.

The advertised duration can range from two to four hours depending on the departure and option. The listed route includes about 110 minutes at the stops and roughly 70 minutes of boat travel, so you should plan for a substantial half-day outing rather than a quick harbor ride.

How to Prepare for the Best Trip

Book an early departure if your schedule allows. Guides have often left promptly and reached the Blue Cave before larger numbers of boats, which means less waiting and more room to enjoy the water.

Bring:

• Swimwear
• A towel
• A secure waterproof case for your phone
• A light layer for the boat
• Money or a card for food and drinks at Sunj Beach

Do not bring oversize luggage. Keep valuables compact and secured, especially during the faster sections of the ride.

If you are an average swimmer, ask for a life jacket before entering the caves. Listen carefully to the guide’s instructions about the entrance and exit points. The caves are beautiful, but they are not a place for careless swimming.

Bad weather can cancel the tour. If that happens, the operator will contact you and issue a refund. You can also cancel up to 24 hours before departure for a full refund, and the reserve-now, pay-later option gives you some flexibility while arranging your Dubrovnik plans.

Who Should Book This Speedboat Tour?

You should book it if you want a fast, active half-day on the Adriatic and feel comfortable swimming in open water. It suits people who like a mix of scenery, snorkeling, music, and a beach stop rather than one long, slow cruise.

It is especially useful during a short Dubrovnik stay. You can spend the rest of the day in the old city or elsewhere, while still seeing the Elaphiti Islands and Koločep’s caves.

Think twice if you are a non-swimmer, dislike speedboats, need a long beach visit, or want hotel pickup. The cave visits involve entering the water, and Sunj Beach is a scheduled stop rather than an all-day beach escape.

The strongest booking tip is to choose the earliest practical departure and bring a waterproof phone case. With those two choices, you give yourself the best chance of quieter caves, good light, and a relaxed finish at Sunj.

Should You Book It?

I would book this tour if your ideal Dubrovnik day includes clear water, a little adventure, and a beach lunch, all without spending eight hours on a boat. The Blue Cave and Green Caves provide the memorable moments, while Sunj Beach keeps the outing from feeling like nonstop swimming.

Skip it if you want dry sightseeing or a long, quiet afternoon. For confident swimmers who want to see more of the coast, the route offers strong value at $73, especially with an early start and a small group.
