Dubrovnik: Blue Cave & Sunj Beach Boat Tour with Drinks

Dubrovnik’s coves are magic, but this tour makes you swim them. You ride out on a speedboat to the Elaphiti Islands, then you get real water time in famous grottoes like the Blue Cave and the Three Green Caves. I like that the route is built around short, scenic travel moments and then hands-on stops, with a crew that keeps things moving.

I also love the value add here: drinks (water, white wine, beer, juice, plus Coca Cola and Fanta) and snorkeling equipment are included, so you do not have to ration your day or your budget. One drawback to plan for is that cave conditions can change what you can do on the day, so you may not always enter every cave area, even though you’ll still get great swimming spots.

Key highlights worth getting excited about

• Blue Cave swim on Kolocep Island, with photo chances and clear-water snorkeling time
• Three Green Caves, a natural swim-through you’ll want to see slowly, not rushed
• Sunj Beach break, sandy, sun-time focused, and a rare stretch of easy relaxation after swimming
• Drinks at each stop, including wine, beer, juices, and soft drinks, plus water to keep it sensible
• Small-group energy, often around 8 people plus the guide and crew, which helps with safety and timing
• A crew that adapts, including when cave entry is too risky, they shift you to alternate snorkel areas

Speedboat start from Dubrovnik dock to Elaphiti Islands

This is a half-day style outing (about 4 hours) that runs on the water, not from one long bus ride. You meet at the dock next to the bus station, and if you get stuck finding the group, contact them on WhatsApp so you do not lose time. There’s also optional hotel pickup in the Dubrovnik city area, but if you choose it, you need to contact them for your exact pickup time. If you miss pickup or do not contact them, refunds are not issued, so I’d set a reminder the day before.

From there, you hop on a speedboat and get to your first swim zone fast. Expect a quick ride (roughly 15 minutes before the first major stop) with a fun, slightly bouncy feel. If you’re prone to seasickness, this is not the right activity type for you, because it’s built around speed and open-water movement.

Blue Cave at Kolocep, what the stop feels like

The first big highlight is the Blue Cave area on Kolocep Island. This is where the tour’s wow factor starts: the boat glides through coastal scenery, and then you stop for swimming and snorkeling time. You’ll typically get a photo stop, a short introduction, and then break time in the water.

What I like about this stop is that the tour doesn’t just drop you off and vanish. The crew gives guidance on how to handle the cave waters, and multiple guides from this operator have been praised for safety and upbeat instruction. Names that came up again and again in customer feedback include Mark, Erik, Anthony, Domenic, and Roko, with people specifically noting that the crew kept everyone comfortable during swims.

A practical heads-up: cave conditions can affect whether you can enter certain cave sections. On some dates, people weren’t able to go inside the Blue Cave but still got taken to beautiful alternate snorkeling spots. So go in with the mindset of: you’re booking the water time and the caves as the plan, but the crew’s job is also to keep it safe and switch options if needed.

Three Green Caves swim-through, the part you’ll talk about later

After another short speedboat stretch (about 10 minutes), your tour shifts from one famous cave area to the Three Green Caves on Koločep. The main event here is swimming through a natural phenomenon, where light plays across the water and the cave interior creates that distinct green look.

This is not “stand on a dock and look.” You’re in the water, snorkeling, and moving along a guided route. The included snorkeling gear matters here because it helps you spend more of your time actually looking at what’s under the surface and less time fiddling.

One more thing I appreciate: timing. The stop is long enough to get into the water, get your breathing under control, and then slow down to enjoy it. People also reported no rush on snorkeling times, which is a big deal in a place where visibility can be stunning and you’ll want a calm rhythm.

And yes, it’s worth noting temperature and season. In late October, some swimmers said you’ll likely want something warm for after, since you get wet and then chill once you’re back on the boat.

Sunj Beach, your reset button after cave swimming

Then comes the easiest part of the day: Sunj Beach. You’ll have about 1.5 hours here, and it’s your chance to dry off, work on a tan, and stop thinking about breathing technique.

Sunj Beach is described as sandy and one of the best beach breaks in the Dubrovnik area. The tour context makes this especially valuable, because the day is mostly caves and water movement, and Sunj is the contrast. You can simply swim again, snorkel a little more if you want, or lounge and recharge.

A small practical note: toilets are available only at the sandy beach, so use them before you start drifting around the sand. Also, towels are not included, so bring one from your hotel or plan to buy/borrow locally.

Loungers are mentioned in customer feedback, but it sounds like you may need to buy food or a drink to use them. That’s common beach-club logic, so I’d treat any sunbed setup as something you support with a small purchase rather than as guaranteed free access.

Drinks on board and at stops, how the included package really works

The drinks are one of the strongest reasons this tour feels like a good deal. You get one drink at each stop, and the included options cover a mix so you can keep it casual: water, white wine, beer, Coca Cola, and Fanta. This is the kind of detail that matters on a boat day, because hydration and re-fueling are not optional when you’re switching between boat, swimming, and sun.

In real terms, this means you’re not paying for a drink every time you climb back on the boat. Multiple reviews praised that the crew kept the drinks flowing, and people mentioned good variety even for those who prefer non-alcohol beer.

If you want a simple way to judge value, do this mental math: you’re paying once for a 4-hour experience that includes boat transportation, snorkeling equipment, crew guidance, and multiple scheduled swim moments, plus drinks timed to the day. At $74 per person, that combination is what makes it feel more like an activity package than a plain “transport to sights.”

What you bring (and what to skip) for an easy, low-stress day

You’ll want swim-ready basics, because the tour is built around water time. Bring:

• Swimwear
• A towel
• Beachwear for the Sunj break

What not to bring: luggage or large bags are not allowed. This is the kind of rule that keeps things safe and prevents clutter in and around the boat. If you’re planning a day trip, travel light and leave big stuff behind.

One more “don’t forget” I’d add: if you snorkel often, consider a waterproof camera or small action cam. A tip in the feedback said an underwater GoPro style camera would be great for Blue Cave footage, since you’ll be in the water long enough to capture the highlights.

Safety, swimming skills, and why the crew matters

This activity requires real comfort in the water. The tour explicitly states swimming skills are essential, including being able to enter the water and resurface, control breathing, float, turn, and move to safety. That’s not a paperwork detail. It’s what keeps the whole operation smooth when the tour is moving from one swim stop to the next.

A lifejacket can be provided on request. In the real world, this is useful for peace of mind, but the message from the tour details is clear: a lifejacket is not a replacement for swimming skills.

This is also not ideal for everyone. It is not suitable for people with mobility impairments, wheelchair users, back problems, people prone to seasickness, people over 70, or non-swimmers. If any of those apply to you, it’s worth choosing a different kind of Dubrovnik outing.

From customer feedback, the guides frequently earn praise for keeping swimmers safe and organized. Names like Matko and Dino came up with comments about making sure passengers were comfortable, assisting when needed, and maintaining a friendly but professional vibe.

What the timing and group style means for your day

You’re not spending the day in a museum line or waiting around. The structure is action-light between stops:

• quick speedboat rides
• then a defined swim and snorkeling window
• then boat time again

People also noted a small group feel, including one mention of 8 participants plus the guide. For you, that usually translates into less crowding at entry points and more attention when you’re adjusting fins or deciding where to enter the water.

And if you’re thinking about when to go, one customer tip is to choose the afternoon for better Blue Cave color. That’s not guaranteed, but it’s a practical angle if you have date flexibility.

Who this boat tour is best for

I’d point this tour at three kinds of people:

You’ll love it if you want adventure with structure, meaning you get guided swimming moments and clear time blocks rather than wandering on your own. You’ll also enjoy it if you like social energy but still want a smaller group, because the setup is more intimate than a big excursion boat.

Finally, it’s a strong match if you want a classic Dubrovnik day break from the city vibe. Many people described it as a refreshing escape, especially when weather around Dubrovnik felt clouded or windy on other days.

It’s not for you if you want guaranteed cave entry every time, if you dislike being in cold or chilly water at certain seasons, or if you do not meet the swimming skills requirement.

Should you book this Blue Cave and Sunj Beach tour?

If you want the Elaphiti Islands to be more than postcards, yes, I’d book it. The best part is the combination: Blue Cave plus Three Green Caves plus Sunj Beach, all in one short day, with snorkeling gear and drinks included. For the price, you’re paying for a real water-based experience, not just transportation.

The only real reason to hesitate is if you are a non-swimmer, have mobility or back limitations, get seasick, or simply dislike swimming. Also, if you’re hoping for a perfect Blue Cave inside-the-cave experience every single day, accept that conditions can affect cave entry and the crew may shift you to alternate snorkeling spots. That’s not a downgrade, it’s the tour prioritizing safety and keeping your time on the water worthwhile.

If you’re fit for a swim day, this is a high-energy, good-value way to see what makes Dubrovnik’s nearby caves famous.
