From Dubrovnik/Cavtat: Blue Cave, Sunj Beach Speed Boat Tour
Book on GetYourGuide →Operated by Dubrovnik Boat Tours - Karuzo · Bookable on GetYourGuide
Speed, swims, and turquoise caves just outside Dubrovnik. What makes this half-day special is the mix of snorkeling-style cave stops and proper beach time, plus the sea views you just can’t get from shore. I also love that the tour keeps you moving in a small group, so it feels like a fun day on the water, not a long bus ride with stops you rush through.
Two things I really liked: you get snorkeling equipment (masks and snorkels) and lifejackets/PFDs for safety, and you’re also supplied with drinks—local beer, white wine, ice tea, cola, Fanta, and water—so you don’t spend your energy hunting a bar between swims. The crew generally keeps the vibe high too, and names like Ivan, Mario, Rino, Dora, and Marco show up in reports as guides who add music and a lively pace to the trip.
One drawback to plan for: the cave swimming can be busy and a bit chaotic in summer, and the water can be choppy at the first stop. That means you’ll want basic swimming comfort and a calm head when boats and swimmers are sharing the same narrow spots.

Key highlights to know before you go

- Blue Cave access means a real swim: you enter through a narrow entrance and get a glowing turquoise-light effect.
- Two easy Green Cave options plus one challenge: one passage is narrow and you swim through to come out the other side.
- Šunj Beach is the payoff stop: a 1-kilometer stretch of fine sand with shallow water for a long way out.
- Drinks are part of the experience: beer, wine, soft drinks, and water are included during the ride.
- Small-group feel: it’s a shared tour, not private, and boats can be around a dozen people depending on the day.
A Small-Group Speedboat Day from Dubrovnik’s Coast

This is built for people who want the Adriatic to be the star of the day. You’ll meet at one of several departure points around the Dubrovnik area, then shift straight onto a speedboat for a quick run out along the coast. The ride style matters: speedboats keep the day tight, so you get multiple swim stops without turning the trip into an all-day commute.
Because it’s a shared small group (not private), you usually get a more personal feel on board. You’re not lining up for every step of the process, and you can actually hear what the crew is saying while you’re getting ready to get wet.
Timing-wise, think in blocks: a short ride out, then two separate cave swims, then a longer beach break on Lopud, then back along the coast. That structure is exactly what you want if you’re traveling with limited time and you’d rather spend it in the water than transferring between destinations.

First Views: Dubrovnik’s Walls from Sea Level

Before you even reach the caves, you get the kind of perspective Dubrovnik is famous for. From the sea, the city walls and red rooftops look dramatic and layered, like you’re seeing the city stacked in the direction of the fortifications.
This matters because Dubrovnik is often photographed from viewpoints. Seeing the walls from water level changes the proportions and makes it easier to understand why the old city looks so protected from every approach. If you’re a first-timer, this “arrive by sea” effect helps you get your bearings fast.
You’ll also pass by the Old Port on the way back, which makes the day feel connected—like you started with a seaward look and finished with the same coastline in a different mood.
Blue Cave at Koločep: The Narrow Swim and Turquoise Light

Koločep Island is where the tour earns its name. The Blue Cave stop is short enough to stay energetic, but long enough for real swimming and photos. This cave isn’t just a surface view. Access is tied to water entry: you swim through a narrow entrance to reach the interior glow.
The “wow” moment is the light. When sunlight hits the water and reflects inside the cave, the color turns bright turquoise and looks almost unreal compared to the darker rock around it. That’s the reason people book this tour instead of doing a land-based cave visit.
What to expect in practice:
- You’ll have included snorkeling gear (masks and snorkels), which helps you stay oriented in clear water.
- There’s time for swimming, snorkeling, and exploring the cave area.
- For the more adventurous, there may be cliff-jumping from the surrounding rocks, depending on how conditions feel that day.
A realistic consideration: cave stops can get crowded, and the water can be choppy near the first site. One rider noted strong waves at the start and emphasized the need to think about how you enter. Translation: if you’re even slightly unsure about your ability to handle uneven footing in moving water, keep your movements slow and follow the crew’s guidance.
Three Green Caves: Easy Snorkels and a Swim Through a Passage

After Blue Cave, the tour moves to Koločep again—this time for the Three Green Caves. This stop is often more about variety than a single “one and done” moment.
You get multiple cave experiences:
- Two of the caves are described as wide and welcoming, which makes snorkeling easier.
- The third is narrow and functions like a passage: you swim through and exit on the other side. That’s a different kind of thrill than floating at the edge.
This stop is the one I’d call the “choose your comfort level” moment. If you want calmer snorkeling, you can gravitate toward the wider options. If you want to test your nerves, the passage cave is the challenge.
Also, keep an eye on how the crew times water entry. In peak season, there can be other boats in the area and more swimmers than you’d like at once. It doesn’t ruin the experience, but it does mean you shouldn’t treat cave stops like quiet nature preserves. Have your swim plan ready: where you want to enter, what you’ll do if the current or boat movement feels stronger than you expected, and when you want to return to the boat.
Šunj Beach on Lopud: Shallow Water, Fine Sand, and Lounge Time

Then comes the break you’ll actually feel in your shoulders and legs: Šunj Beach on Lopud. You’ll get around 1.5 hours here, which is plenty to swim, dry off, and settle in with a snack or drink—without feeling like you’re constantly “on” for the group.
Šunj is known for its beach-and-water setup. It’s about a 1-kilometer stretch of fine white sand, and the water stays shallow for nearly 100 meters out. That’s huge. It means you can float, wade, and swim without needing to be a strong open-water swimmer. Even if your cave swimming was intense, Šunj gives you a softer landing.
What about services and comfort? Beach bar operations begin in May, so if you’re traveling in shoulder season you might find the scene quieter. On the sunny-day side, there’s a bar with blue umbrellas where ordering a refreshing drink can get you a complimentary sunbed and umbrella. In one case, a rider mentioned a €15 bar setup tied to getting chairs—so the key is: plan to spend a little if you want the loungers, and confirm what’s included when you arrive.
Bathrooms are mostly your only question for Šunj. Toilets are usually available at the beach on Lopud, and sometimes a speedboat toilet is available. Ask the crew on the day if you’re sensitive to timing.
Drinks, Music, and the On-Board Vibe That Keeps It Fun

This tour isn’t shy about keeping you comfortable while you’re out there. Drinks are included, and the list covers the basics most people want after swimming: local beer, white wine, ice tea, cola, Fanta, and water.
In real terms, this helps in three ways:
- You’ll be less tempted to rush back from swim time because you know a cold drink is coming.
- It makes the ride feel like part of the activity, not just transport between stops.
- It’s easier to socialize, because people aren’t scrambling for cash or planning a separate stop.
The mood on board also matters. Multiple reports mention music while cruising, with some describing it like a disco on the return ride. That kind of energy can be exactly what you want on a vacation day. If you’re the type who prefers quiet, you might still enjoy the ride for the scenery, but just know the playlist can be part of the experience.
Safety-wise, the tour provides lifejackets/PFDs, and there are also noodle floaters available as a better alternative if you want extra help. Lifejackets aren’t a substitute for swimming ability, though. The day still requires basic swimming skills: entering the water, resurfacing, floating, turning, and swimming to safety.
Who This Tour Fits Best (and Who Should Skip It)

This is not an everyone-sails type of trip. It’s fun, but it’s active and water-based.
It suits you if:
- You can swim and feel comfortable in open water.
- You like snorkeling and you want to compare cave swimming versus beach swimming.
- You don’t mind a speedboat ride over waves.
- You want a clear itinerary with a few major highlights instead of lots of quick stops.
It’s not suitable if:
- You have back problems.
- You’re a wheelchair user.
- You’re a non-swimmer.
- You’re prone to seasickness (the ride speed and waves can be a factor).
- You’re over 80.
If you’re on the edge with motion sickness, I’d treat that as a serious planning note, not a minor inconvenience. One rider specifically advised taking travel sickness pills if you tend to get motion-related symptoms.
Price and Value: Is $71 a Fair Deal?

At about $71 per person for a 4–5 hour outing, the value depends on what you’re comparing it to.
Here’s what you’re actually buying for that price:
- Multiple swim stops, not just one cave and done.
- Snorkeling gear included (masks and snorkels).
- Drinks included for the time you’re on the water.
- A long enough beach break to make the day feel like a getaway, not a quick splash.
What’s not included: lunch. So if you get hungry during your return, you’ll want a plan for afterwards.
To me, the deal makes sense if you’ll use the included items: you’ll swim, snorkel, and you’ll take advantage of the drink list. If you’re mostly looking for views and prefer staying dry, you might find the active parts don’t match your style.
Also, consider crowding. In peak summer, caves and cave entrances can get congested with other boats and swimmers. The crew can’t change that. But if you’re flexible and patient, you’ll still get the color, the swimming, and the quick satisfaction of moving from one highlight to the next.
Booking Tips That Make the Day Smoother

A few practical moves can upgrade your experience fast.
- Bring swimwear and a towel. You’ll be changing in motion, and you’ll want to dry off quickly after the caves.
- If you like photos, think about a phone case for underwater shots. One rider specifically called out getting a case that goes underwater for cave pictures.
- Be ready for entry steps and uneven water at the caves. Even strong swimmers can get thrown off by footing when waves hit the boat approach.
- Plan for the boat vibe. Music is part of the mood for many crews, and it can get loud. If you’re sensitive, bring earplugs.
- If the sea is rough, the captain may change the order of cave visits depending on weather and sun position. That’s a normal adaptation, not a sign that something went wrong.
Seasonal reality: Šunj beach bar services begin operating in May. From November to April, the beach stop is adjusted (either Lopud village or Koločep village) because Šunj isn’t open and the sea is cold. If you’re traveling in winter, expect a different feel: less “sun and loungers,” more “coastline time with a practical stop.”
Should You Book This Dubrovnik Blue Cave Speedboat Tour?
I’d book this tour if you want a high-energy, water-first day that combines Blue Cave, Green Cave passage swimming, and Šunj Beach in one tight window. It’s especially worth it if you can swim comfortably and you’ll actually use the snorkeling gear and included drinks.
Skip it if you’re dealing with back issues, mobility limits, or you’re a non-swimmer. If you’re prone to seasickness, be honest with yourself about whether a speedboat ride in open water will make you miserable.
If you’re the type who likes a little adrenaline, loves snorkeling, and wants Dubrovnik’s coastline from the sea, this tour is one of the most efficient ways to turn a half-day into a highlight.
