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

Blue Cave has a way of messing with your sense of color. You get the chance to swim and snorkel in Blue Cave on Koločep, then cool off with Šunj Beach on Lopud, all in one lively half day on a small speedboat. I really like that the tour handles the hard parts for you, with included masks and snorkels and a drinks setup that keeps you comfortable between swims. One thing to plan for: this is real water time, and it does include swimming through caves, so basic swimming skills matter.

I also appreciate the perspective shift you get right away, cruising along Dubrovnik’s coastline with the city walls and red rooftops visible from the sea. Expect short, punchy segments of travel, a few swim breaks, and enough downtime on the beach that you do not feel like you’re just rushing from one splash to the next.

Key highlights you’ll actually feel

• Koločep cave swimming: Blue Cave access is by swimming through its narrow entrance.
• Three Green Caves options: two easier snorkeling-friendly caves plus a third narrow passage that can take swimmers through to the other side.
• Šunj Beach reset: sandy and shallow for a long stretch, so it’s easy to wade, swim, and relax.
• Snorkeling gear included: masks and snorkels are provided, with lifejackets and noodles available for extra help.
• Drinks included during the ride: local beer, white wine, ice tea, cola, Fanta, and water keep the pace easy.
• Crew personality on board: many departures are led by guides such as Ivan, Mario, Rino, or Leo, and the vibe tends to be fun with music.

On the Water Fast, Dubrovnik From the Sea

This tour is built for people who want maximum coastline in minimum time. From Dubrovnik (and also Cavtat, Mlini, and Srebreno on certain departures), you jump into a speedboat and get moving quickly. That matters, because Dubrovnik’s islands look best when you see them from water first, with the Old Town fortifications looming above the Adriatic.

The first payoff is the ride itself. As you cruise past the coastline, you get a dramatic, practical viewpoint of the city walls and rooftops that you simply cannot replicate from shore. It also sets the mood for what comes next: you’re not watching the scenery from a bus window, you’re living it with wind on your face and salt in the air.

You should also note that this is a shared small group tour, not private. Most departures run with enough people for it to feel social, but small enough that you can still find your space for photos and swapping swims.

Getting to Koločep: Short Boat Segments, Big Swim Energy

Once you’re out on the water, the plan is straightforward: boat in, swim, snorkel, repeat. The boat time between stops is usually brief, so your attention stays on what is in front of you. That pacing is one reason this works well as a half-day outing. You get multiple water activities without losing the day to logistics.

Koločep Island is the key. Both the Blue Cave stop and the Three Green Caves stop are on Koločep, meaning you’re not constantly changing regions or dealing with long transfers. The tradeoff is that the day is physically active. You’ll be moving between boat seating and water entry multiple times, and in rougher conditions you’ll want to stay mindful when people are climbing in and out.

If you’re prone to motion sickness, this is also where you should take it seriously. The route is done by speedboat, and the waves can be lively on the way back. A simple precaution can make the difference between enjoying the ride and spending the day focused on your stomach.

Blue Cave on Koločep: The Narrow-Entrance Swim

The Blue Cave is the star name, and it earns it. The cave’s look comes from light filtering in, reflected off the sea, which produces that glowing turquoise effect people come for. What makes it memorable is how you reach it: you access the cave by swimming through a narrow entrance.

That detail changes the whole experience. This is not a “look from the deck” stop. You’ll likely put on your mask and snorkel and get in the water, following the crew’s timing. The water is usually clear enough for good visibility, but you still want to think of this as a swim first, sightseeing second.

What I like about Blue Cave on this tour:

• You have included snorkeling equipment, so you can focus on enjoying the cave rather than searching for gear.
• You get actual time to float, swim around, and explore the interior area at a comfortable pace for a shared group.
• If the conditions and your confidence allow it, there’s often the chance for cliff-jumping from nearby rocks, which can turn the stop into a highlight moment.

A realistic consideration:

• The first entry can feel busy and a bit more chaotic than you might expect in peak season, especially when multiple boats are present. Keep your wits about you around moving boats and swimmers.

Practical tip: bring a towel and consider a waterproof phone case if you want underwater cave photos. Clear water plus real cave light can make your phone screen look boring compared to what your camera could capture.

Three Green Caves: Easy Snorkels and the Brave Passage

After Blue Cave, you head to the Three Green Caves, also on Koločep. This stop is designed to fit different comfort levels, because the three caves are not all the same experience.

Two of the caves are wide and welcoming, meaning they work well for snorkeling without feeling like you are doing an obstacle course. The third cave is the wild card: it’s a narrow passage that can lead swimmers through the island and out on the other side. If you’re comfortable in the water and like a challenge, this is the one that tends to feel most unforgettable.

I like how this is structured. You are not forced into the most intense option. You can choose your own level of bravery within the stop, and your confidence usually determines how much of the cave experience you get.

One heads-up:

• Water conditions can affect entry, and boats crowded around the area can make timing tighter. Nothing ruins the experience, but it’s smart to stay flexible, follow the crew closely, and move efficiently when it is your turn.

Šunj Beach on Lopud: Sandy, Shallow, and Easy to Stay Put

The final stop is Šunj Beach on Lopud, a one-kilometer stretch of fine white sand with shallow turquoise water. The best part for your comfort is that the sea remains shallow for nearly 100 meters out, so you can wade, swim, and relax without feeling like you need to commit to a deep-water swim.

This is where the tour shifts gears from active cave time to pure downtime. You get about 1.5 hours on shore, which is long enough to rinse off, reapply sunscreen, swim again if you feel like it, and still have time to linger.

A detail that makes Šunj extra practical: the boat anchors as close to the beach as possible for easy disembarkation. That reduces friction at the end of the water-heavy day.

What you can do with your time on the beach:

• Swim and float in the calm, shallow water.
• Sunbathe and reset after the caves.
• Enjoy beachfront services if you want them.

And here’s a bonus many people end up loving: if you order a drink at the beachfront bar with blue umbrellas, you receive a complimentary sunbed and umbrella. So you can turn beach time into a comfortable, “we booked this for ourselves” kind of experience, without having to guess how seating works when you arrive.

If you go in months when Šunj services are not operating, you’ll see a different setup. From November to April, the beach stop is adjusted because Šunj isn’t open and the sea is cold. On those dates, you might end up stopping in Lopud village or Koločep village instead, depending on the day and what is open for cafés, restaurants, and shops.

Drinks, Music, and the Real Value of $71

The price is $71 per person for a 4 to 5 hour outing, and the math makes sense if you compare it to buying drinks and snorkeling gear separately. This tour includes local beer, white wine, ice tea, cola, Fanta, and water, plus snorkeling equipment (masks and snorkels).

That included drinks part matters more than it sounds. After multiple swims, it’s not just about taste, it’s about comfort. You get something cold between water sessions, and it keeps the ride feeling like a holiday rather than a workout you have to recover from in secret.

I also like the energy on board. Many guides and skippers bring their personality to the trip. People mention guides such as Ivan, Mario, Rino, Leo, Peter, Dora, Marco, and Tommy, and skippers like Ivan specifically for music and keeping drinks coming. In practice, that usually means a friendly atmosphere, sometimes with music playing on the boat and during the return ride.

Group size can also influence how fun the day feels. One review notes a boat with no more than 14 people, which is a good sign for a shared tour because you’re not constantly bumping elbows.

What is not included:

• Lunch. You’ll need to plan for food on your own when you’re finished.

Finally, consider seasickness risk as part of “value.” If you know you get sick in motion, this is one place where you might spend the money but lose your ability to enjoy it fully. If that’s you, prepare accordingly.

What the Captain May Change, and Why You Should Be Flexible

The tour is guided by conditions at sea. The captain can change the itinerary in bad weather, and also for sun position, which affects how the cave light looks. That means you should pack your mindset for a plan that adapts, not a rigid script.

If weather is rough, you may see stop order swap around. In a typical scenario, you still visit Blue Cave and the Green Caves and you still end with a beach-like break, but the sequencing might shift depending on conditions.

This flexibility is also why the tour often feels smooth on the day. The captain is making decisions to keep you safe and maximize the experience possible with the day’s conditions.

Safety, Swimming Skills, and How Lifejackets Work Here

This is the part you should read like it’s for you, because it is. Lifejackets (PFDs) are always available for safety, but they are not a substitute for swimming ability. You still need basic swimming skills, including the ability to enter the water, resurface, float, turn, and swim to safety.

Noodles are available as a better alternative for extra flotation. That can be helpful if you want support while you float and snorkel.

This tour is also not suitable for:

• People with back problems
• Wheelchair users
• Non-swimmers
• People prone to seasickness
• People over 80 years

So if you’re in any of those categories, you should probably pick a different Dubrovnik experience that stays more on the dry side or uses calmer water.

Toilets and Timing: Small Details That Save Stress

Water days can get tricky when you wonder where you will rinse, use the restroom, or take a breather. Here’s the practical reality: toilets are usually only available at Šunj Beach on Lopud. Sometimes the speedboat has a toilet, but that depends on the boat on the day, so ask the crew when you board.

Timing-wise, the day is organized around short travel legs and set breaks:

• Speed time between stops
• About 30 minutes for Blue Cave time
• About 30 minutes for the Green Caves stop
• About 1.5 hours of free time on Šunj Beach

If you’re trying to squeeze in this tour on a tight vacation schedule, the 4 to 5 hour duration is a good fit. You still have a good chunk of the day to enjoy Dubrovnik Old Town before or after.

Who Should Book This Tour, and Who Should Skip It

This is a great pick if you want a mix of:

• Speedboat cruising and coastline views
• Real snorkeling time with masks and snorkels provided
• Cave swimming experiences that feel active, not passive
• A relaxing sandy beach stop after the adrenaline

It’s especially appealing for couples and friends who are comfortable with water, and for people who want a fun group day that still feels well-timed. The included drinks help it feel like a treat.

You should skip it if:

• You do not swim, or you are uncomfortable with basic water skills
• You’re prone to seasickness
• You have mobility or back issues that make hopping in and out of the boat stressful
• You need wheelchair accessibility

Should You Book the Blue Cave and Sunj Beach Speedboat Tour?

If you’re choosing between a standard sightseeing trip and a water-focused day, this is the better bet. The included snorkeling equipment plus drinks plus a beach break gives you more “experience per hour” than many boat tours that nickel and dime you on gear and beverages.

Book it if you want:

• Koločep cave time with Blue Cave and Three Green Caves
• A sandy, shallow beach finish at Šunj
• A small shared group day with guides like Ivan or Mario bringing energy and music

Skip or rethink it if you:

• Know you get seasick easily
• Are not comfortable swimming and entering cave areas
• Need reliable toilets at multiple stops

If you’re a confident swimmer who loves clear water and wants Dubrovnik from the sea, this tour is one of the most straightforward ways to turn half a day into a real highlight.
