Dubrovnik: Blue Cave Tour by Speedboat

Dubrovnik’s caves are a short, salty ride away. This Blue Cave by speedboat tour packs snorkeling in crystal-clear waters with real time at the Blue Cave and the Three Green Caves, plus a laid-back beach break on Šunj.

I especially like how the day is built for variety, not just one photo stop. You get a mix of swimming, cave exploring, and then a sandy shore where you can dry off, drink something cold, and enjoy the sea air. One thing to watch is the meeting point, since multiple boats often leave and it can take a moment to identify the right one.

Key highlights you can plan around

• Blue Cave + Three Green Caves in a single half-day route, with short, efficient swim stops
• Snorkeling gear included, so you do not have to track it down in town
• Open speedboat with drinks on board, expect wind, salt spray, and a fun ride
• Šunj sandy beach time with an easy walk through shallow water before you hit the sand
• Jumping into the sea from natural rocks, when conditions and your comfort level match
• Guide in English and Croatian, with the captain keeping the pace steady

Blue Cave and Three Green Caves, in a 4-hour hit

This tour is designed like a greatest-hits playlist. In about 4 hours, you cover a speedboat ride, two cave areas, and a beach stop long enough to actually feel like you switched gears. That matters because Dubrovnik’s coastline looks best when you move, not when you stand around waiting.

The main draw is the mix of cave time and water time. You are not just looking at the caves from the boat. You will swim and snorkel around the cave entrances, and you’ll have moments where you can just float, catch your breath, and let the water do its thing. The other win is the beach finish on Šunj, which gives you a soft-sand landing after all that wet time.

Timing is tight, but not rushed. Most stops are built around practical sessions, like about 45 minutes at the Three Green Caves, roughly 60 to 90 minutes at Šunj, and around 30 minutes at the Blue Cave. That’s a good match for people who want a fun outing without losing a whole day.

Getting started: the Knjižnica za društvene znanosti meeting point

The tour starts at Knjižnica za društvene znanosti. The operator’s staff is supposed to be waiting there, and you are advised to look for Antonio or someone in a red shirt tied to Adriatic Boat Tours. That sounds simple, but the reality is that this area can have several departures happening at once.

My advice: get there a little early and scan for the red shirt and for the staff names. If you feel unsure, ask quickly. One person noted that finding the exact boat took a moment because multiple boats left from the same general area. You do not want to lose time if you’re coordinating other plans that day.

Once you’re with the right group, things usually move fast. You will board, get your snorkel gear and waterproof bag details, and head out.

The speedboat ride: what it feels like, and why it matters

You’re in an open type speedboat, so this is not a sit-back-and-ignore-the-weather kind of trip. You will feel wind, cold, and sea spray as you ride between stops. If you hate getting splashed, you’ll want to dress with that in mind.

The upside is that the ride itself is part of the experience. You get sea breeze in your face, sun on your shoulders when it’s out, and constant coastal views as you hop from island to island. Plus, the boat is equipped with cold drinks, which helps a lot after you’ve been in and out of the water.

A big practical point: there is no toilet on the speedboat, and the only restroom is at the beach stop. That is one of those details that can quietly change your comfort level for the whole trip. Use the restroom before departure, and if you feel like you need a bathroom later, time it around the beach.

Also, this tour is described as not suitable for people prone to seasickness. If you know you get motion sick on boats, treat that as a serious warning and consider a different plan.

Stop 1: Three Green Caves on Koločep, snorkel time on purpose

Your first island cave stop is the Three Green Caves on Koločep. Expect around 45 minutes here, and it is structured so you can do the two most important tasks: get in the water and get oriented enough to explore without panicking.

This is a swim-and-snorkel stop. The rules are simple: you need to swim to access the caves, and you may have to walk through shallow water to reach the sandy areas later on the day. If you’re a decent swimmer, you’ll probably find the water time more fun than stressful. If you’re not, you may feel rushed or uncomfortable.

You’ll also likely be doing some photo time. The stop includes a photo stop plus free time for swimming and snorkeling. That combination is key. Caves are gorgeous, but you also need a little time to catch your breath, adjust your goggles, and take a few shots without holding up the group.

One more note: the sun can be strong. Even if the ride is breezy, you can still burn while you’re floating or climbing around in the glare. Bring sunscreen and plan to reapply if you get long sun exposure.

Practical tip for cave snorkeling

Keep your snorkel gear handy and give yourself a minute to adjust before you go under. If you spend the first few minutes figuring things out underwater, you’ll lose time and confidence.

Stop 2: Šunj beach on sandy land, not just a quick stop

Next comes the sandy beach stop at Šunj. You get around 60 to 90 minutes, which is long enough to do more than rinse off. This is where you earn the “treat yourself” part of the tour.

There’s supposed to be a beach bar, and you’ll have the option for cocktails or food. Even if you don’t plan to order much, the beach break changes the whole mood of the outing. Instead of chasing cave moments in your swim schedule, you can sit, dry a bit, and refocus.

You should also know the access detail: you will need to walk through shallow water to get to the sandy beach. That is not a problem for most people, but it’s still worth calling out. Wear flip-flops or water-friendly shoes, not footwear that you hate getting wet.

And remember the sun. The tour includes plenty of water time, but beach time means direct light on skin. If you forget sunscreen or go in only lightly protected, this stop is where you’ll pay for it.

Stop 3: The Blue Cave on Kolocep, the main event

The last big moment is the Blue Cave on Kolocep Island. You’ll spend about 30 minutes there for swimming and exploring, which makes it the shortest stop, but also the one people talk about most.

The Blue Cave is a “get in, see what you came for, and enjoy it” kind of place. You will need to swim to get into the cave area, so being comfortable in the water matters. You can also jump into the sea from natural rocks surrounding the islands, and this typically happens more than you might expect during the Blue Cave portion, simply because it’s fun and the group energy often shifts toward playful confidence once everyone realizes the conditions are manageable.

If you’re not into jumping, you can still have a great time by swimming, snorkeling near the cave area, and taking a few calm moments to look around. Your comfort level sets the pace here, not the group.

One last practical consideration: towels are not included. If you want to feel comfortable after your final swim, bring a towel. Otherwise, you’ll be that person trying to dry off with what you’ve got, while everyone else looks relaxed.

What’s included, and what you’ll still want to bring

Here’s what the tour covers, and it’s enough to reduce stress if you pack smart:

• Snorkeling gear
• Waterproof bag
• Drinks: water, beer, wine, and coca cola
• Fuel

What’s not included:

• Food
• Towels
• Tips for the crew
• Hotel pickup and drop-off

I like that drinks are included because it makes the tour feel complete. When you’re wet, tired, and in the sun, having cold water and a cold beer option helps. It’s also helpful that there’s coca cola in addition to alcoholic options, so you can choose what suits you.

What you should bring is spelled out, and I agree with it:

• Sunglasses
• Swimwear
• Towel
• Camera
• Sunscreen
• Flip-flops
• Credit card and cash

You might think the credit card and cash details are extra, but since the beach bar and possible food are not included, having payment options makes it easier to handle what you want in the moment.

Also, no pets, no smoking, and no large luggage. Keep it simple, because you’ll be near water and on a boat with limited space.

Price and value: is about $82 worth it?

At $82 per person for a 4-hour excursion, you are paying for three things at once: speedboat transport, cave access time, and snorkeling gear plus drinks. In other words, you’re not just buying a ticket to a viewpoint. You’re buying a half-day water experience.

For value, the big wins are:

• Gear is included, so you avoid rental hassle
• Drinks are included, which makes the beach stop less awkward
• Three cave-related moments happen within a short window, and the boat takes you between them

If you compare this to trying to DIY cave snorkeling on a busy day, the tour’s structure is what you’re really paying for. It saves time, handles the route, and keeps everything moving on a schedule that fits a half-day.

That said, the price may feel steep if you mainly want photos from shore. This tour is built for swimming and snorkeling. If you do not plan to get in the water, you might feel like you paid for a swim-centric day.

Who should book this Dubrovnik speedboat caves tour

This outing is a good fit if you want:

• Snorkeling time without having to plan boats, gear, and route
• A quick taste of island hopping around Dubrovnik
• Sun, sea breeze, and a beach finish at Šunj
• Comfort with an open boat and active stops

It might not be your best match if:

• You get seasick easily
• You have back problems, or mobility limitations that make swimming and shallow-water walks hard
• You are pregnant
• You need wheelchair access
• You’re traveling with a young baby under 1 year

One of the review takeaways that lines up with your decision-making is that the vibe is often upbeat, with the captain keeping the ride fun through music and steady control. A named captain, Mario, was described as excellent, with great music choices and strong boat handling. That kind of experience matters when you’re riding an open speedboat and you want the trip to feel safe and relaxed.

Should you book it? My practical verdict

I’d book this tour if you’re excited by water time and you want Dubrovnik’s caves and the beach, all without stretching your day. The mix of Three Green Caves, Šunj sandy beach, and the Blue Cave gives you variety, and the included gear plus drinks make it easy to travel light.

Skip it or think twice if you’re not a confident swimmer, hate motion on boats, or strongly prefer dry, shore-based sightseeing. The cave access depends on swimming, and the beach involves walking through shallow water, so your comfort level in and around the sea is the deciding factor.

If that sounds like you in a good way, you’ll likely come away feeling like you packed a lot of real Dubrovnik coastline into a single half-day.
