From Dubrovnik/Cavtat: Blue Cave, Sunj Beach Speed Boat Tour

This Blue Cave and Sunj Beach speedboat day is interesting because it strings together three very different Adriatic moods in one short outing: fast sea views, stop-and-swim caves, and then a sandy island payoff. You also get the dramatic bonus of Dubrovnik’s city walls from the water, which feels like a whole new way to see the postcard.

I love the practical mix of included gear and included drinks. Snorkeling masks and snorkels come with you, and the crew keeps you refreshed with local beer, white wine, ice tea, cola, Fanta, and water. I also love the final free time on Šunj Beach on Lopud, where the water stays shallow far out, so it’s easy to enjoy without rushing.

One consideration: you need basic swimming skills, and you may share the cave area with other boats. If you’re not comfortable getting in, resurface, float, and swim to safety, this trip will feel like work instead of fun.

Key Things To Know Before You Go

• Dubrovnik’s walls from the sea: you see Old Town rise straight out of the Adriatic.
• Koločep Island cave swimming: the Blue Cave and Three Green Caves are built for snorkeling and swimming, not just staring.
• Included drinks keep the mood light: beer, wine, sodas, and water are part of the experience.
• Šunj Beach is the payoff: about 1.5 hours of free time on a sandy Lopud beach.
• Plans can shift with conditions: the captain can reorder stops depending on weather and sun.
• Small-group feel, big water energy: music on board and wave bouncing are part of the fun for many groups.

The Short Reason This Tour Feels Like a Win

This is not a long, complicated excursion. It’s a half-day that’s built around three “you’ll remember this” moments: the sea-cave swim, the unique cave-to-water sightlines, and then the beach where you can finally slow down.

At $71 per person, the value comes from the combination. You’re paying for transportation by speedboat plus structured swim stops plus the snorkeling kit plus drinks. Many similar tours slice this up and charge extra for at least one of those.

From Dubrovnik Or Cavtat, You Start With The Walls Over Your Shoulder

Departures run daily and can pick you up around Dubrovnik and nearby areas like Cavtat, Mlini, and Srebreno, then head toward the Old Town area for the main start. Your exact meeting point can vary, so don’t leave it to chance. Aim to arrive early enough to find your pier and settle your bag.

Once you’re out on the open water, Dubrovnik’s city walls stop being a background detail. From sea level, you see the fortifications and red rooftops stacking up dramatically, and the whole Old Town looks built for looking at from offshore.

Koločep First: Blue Cave Swimming, Snorkeling Gear, And Real Entry Tips

The first swim stop is typically on Koločep Island at the Blue Cave. The cave is known for its narrow entrance and the glow inside, created by turquoise light reflecting through the opening and the sea beyond.

You’ll be given snorkeling equipment (masks and snorkels) before the swim breaks. This matters because it makes the stop more than a quick splash. You can actually float, check the water clarity, and snorkel your way through what you can see safely.

Two practical tips that help here:

• Expect others in the water. It can get busy, and the timing of entries can feel a little chaotic at peak moments.
• Pay attention to how you enter. Some boats report stronger waves around the first cave stop, so use the moment where you can step in without fighting the water.

If you’re comfortable and conditions allow, there may be opportunities for more adventurous moments like cliff-jumping from nearby rocks. Your guide and crew will decide what’s safe in the moment.

Three Green Caves On Koločep: Different Swim Experiences In One Stop

After another short boat ride, the tour continues to the Three Green Caves, also on Koločep. This is one of the reasons the trip earns its name and earns repeat swims as a concept. You’re not just seeing one cave trick.

What makes this stop interesting is the variety in swim access:

• Two of the caves are wider and easier to approach for straightforward snorkeling.
• The third is narrower and can create that unforgettable through-swim feeling, with an exit point on the far side.

That means you can choose your comfort level. If you want a calmer swim, aim for the wider options. If you want a challenge and you’re confident in your swimming, the narrow passage is the one people talk about.

Šunj Beach On Lopud: Shallow Water, Sand Time, And How To Get Loungers

Then comes the main relaxation break at Šunj Beach on Lopud Island. This is a one-kilometer stretch of fine white sand with shallow turquoise water. The key detail for comfort is that the sea stays shallow nearly 100 meters out, so you can swim, wade, and hang out without immediately battling deep water.

You get about 1.5 hours of free time ashore. That’s enough to swim, dry off, and decide if you want to stretch out with a drink or just enjoy the water and the view.

Here’s a small tip that can upgrade your beach time: bars on Šunj use blue umbrellas, and ordering a drink can come with a complimentary sunbed and umbrella setup. If you want that convenience, plan to get your drink early in your beach window so you’re not scrambling later.

Food is not included on this tour, so your beach lunch plans are on you. The good news is that the beach break is timed to let you find options without feeling like you’re trapped in a schedule.

How The Boat Ride Feels: Drinks, Music, And That Speedboat Bounce

A lot of the tour’s energy comes from the time between swim stops. You’re on a speedboat, so you’ll feel movement, spray, and that quick, fun sense of momentum.

Drinks are part of the experience, not an afterthought. The crew provides local beer and white wine, plus ice tea, cola, Fanta, and water. Several guide personalities come through in how the day runs, with names like Ivan and Mario showing up repeatedly in the vibe people report, often paired with a friendly, lively tone.

Music can be loud at times, and some boats switch to a party feel on the return. If you’re sensitive to sound, bring some ear protection or plan to take breaks on the quieter side of the boat.

Timing, Waves, And Why “Small Group” Still Means Shared Caves

This is a shared small-group tour, not a private charter. That affects two things: how long you wait and how crowded the swim stops feel.

At the caves, other boats can be in the water at the same time. You can’t control that. What you can control is your attitude and preparation. Keep your snorkel and mask ready, follow the crew’s entry and exit instructions, and avoid rushing when boats reposition.

Also, the sea and wave conditions can change the feel of each stop. The captain has the right to change the itinerary if weather or sun position makes a different order smarter. In practice, this means you should pack for “flex day” energy, not “perfect conditions only” expectations.

What To Bring So You Enjoy Every Stop (Not Just The Beach)

You don’t need a lot of gear, but the right items make a difference.

Bring:

• Swimwear
• Towel

You might also want:

• A waterproof phone case. People who go to these caves for photos often wish they had one ready.
• Water-friendly shoes if you prefer stability on entry areas.

On safety and comfort: lifejackets (PFDs) are available for everyone, but they are not a substitute for swimming ability. Noodle floaters may also be available as an easier option for additional support.

Safety Reality Check: Swimming Skills Are Non-Negotiable

This tour is not for everyone. It is not suitable for non-swimmers and is not recommended for people prone to seasickness. There’s also a no-go list that includes wheelchair users and people with back problems, and it’s not suitable for people over 80.

If you do swim, the tour expects you to be able to:

• enter the water
• resurface
• float
• turn
• swim to safety

If your confidence is only “I can float at the beach,” you should think carefully. Cave swims and cave approaches are not like a calm swimming pool. The right mindset matters, and so does pacing yourself.

Toilets: Plan For The Beach, Then Ask

Toilets are usually available at Šunj Beach on Lopud. Sometimes a speedboat with a toilet is available, but you should ask the crew on the day because it can vary.

If you’re timing your water intake, it’s smart to treat the beach stop as your reliable restroom window.

Price And Value: Why $71 Can Make Sense Here

On paper, $71 can look steep for a half-day. Here’s why it can still feel like good value:

You’re getting:

• transport by speedboat (and a day that’s focused on sea access)
• multiple swim stops centered on caves and islands
• snorkeling equipment included
• drinks included on board

If you’re the type who would otherwise pay separately for a cave boat, rent snorkel gear, and buy drinks at each stop, the math shifts in the tour’s favor fast.

The only “cost” you might feel is optional: lunch on your own at Šunj, plus any beach bar extras. Still, you control that.

Who This Tour Is Best For (And Who Should Skip It)

This is a strong fit if you want:

• a classic Dubrovnik-area experience that includes actual water time, not just scenic passes
• cave snorkeling or cave swimming as the main event
• a half-day plan that doesn’t crush your schedule

It’s also a good choice for groups who want a social vibe without the hassle of planning. The boat experience tends to stay lively, and guides like Ivan and Mario often bring humor and clear direction.

Skip it if:

• you cannot swim comfortably
• you get motion sick easily
• your mobility is limited (wheelchair access is not supported)
• you have significant back issues

Should You Book This Blue Cave And Sunj Speedboat Tour?

If your ideal day is water, views, and the kind of snorkeling where you can actually see why people come to Koločep, then yes, you should book it. The structure is simple, the stops match the theme, and the included drinks make the whole outing feel easy.

Book with confidence if:

• you can swim well enough to handle cave entry and exit
• you want a memorable mix of cave time and real beach downtime
• you like a small-group speedboat vibe with music and energy

Think twice if:

• you’re seasick-prone or very uncomfortable with moving boats
• you hate crowds, because cave stops can get busy with other swimmers and boats

If you go in prepared, this tour delivers exactly what its name promises: Blue Cave excitement, Green Caves variety, and Šunj Beach sand time to close out the day on a calmer note.
