Crystal water, fast boat, famous caves. What makes this Dubrovnik Blue Cave tour stand out is the mix of cave time in Koločep and the easy deck life, with hosts like Vinny and Karolina keeping the vibe friendly and the drinks moving. One thing to consider: this is an active water day, so if you’re uncomfortable getting in and out or you’re prone to seasickness, you’ll want to think twice.

The boat itself is built for sun and sea views, with snorkeling gear, life jackets, and onboard toilets/showers—plus sunbeds and shade under the hardtop. You’re also cradled between stops: quick speedboat hops, focused swim windows, then a proper beach break at Šunj.

Key highlights that matter

• A tight 4-hour loop: fast hops between the sea stops, so you get a lot without losing a whole day to travel.
• Koločep caves with real snorkeling time: multiple cave visits plus swim/snorkel windows designed for different comfort levels.
• Unhurried Šunj Beach break: an hour to relax on sand with calm, shallow water.
• Blue Cave photo-and-swim stop: short but unforgettable, with the option to snorkel or swim depending on conditions.
• Crew-led comfort and safety: guidance in the water and gear support (life jackets, and in some cases extra swim aids).
• Onboard drinks included: alcoholic and non-alcoholic beverages served throughout the tour.

Finding MARINERO excursions at Dubrovnik’s Old Town Harbor

Your day starts in the Old Town Harbor. Look for MARINERO excursions at the small pier in the harbor area, next to the restaurant Lokanda. It’s the kind of meeting point where you’ll want to show up a few minutes early so you can locate the right boat without stress.

Pickup is optional if you’re staying in Dubrovnik (and you’ll need to enter your hotel or accommodation address during booking). If you do request pickup, the driver waits no longer than 5 minutes after the scheduled time—so have your group ready.

Why this matters: this tour runs on water schedules. Getting there on time helps you start calmly instead of rushing into the first speedboat ride.

The 25-minute speedboat run: views you can’t get on foot

After boarding, you’ll set off for about 25 minutes on the water. This is more than just transport. You’ll be cruising along coastline and looking at rugged edges of the Adriatic from a spot that’s simply not available from the walls.

What you can do during this phase:

• Get your first round of photos and a feel for the boat’s pace.
• Relax on deck with included drinks.
• Let the open air cool you down before the swim-heavy stops.

Most people like this start because it’s an immediate change of scene. One moment you’re in Old Town bustle; the next you’re in open water with the sea doing all the heavy lifting for scenery.

Koločep’s three green caves: the main swim session

The first major stop is Three Green Caves on Koločep, with roughly 45 minutes on site. This is your “water time” anchor of the tour: there’s a brief photo stop and visit time, then you settle into swimming and snorkeling.

Here’s how it usually plays out on the water:

• You’re given snorkeling equipment and life jackets.
• You get time to explore in the water and look around for fish and formations.
• Drinks and small onboard hospitality continue through the stop (including alcoholic and non-alcoholic options).

A couple useful details from experience-based feedback:

• The cave route can include spots where you have to swim through tighter areas. Some entrances feel more challenging than others, so better swimmers tend to enjoy the full range of what’s possible.
• Crew members often stay close. Several guides were described as getting in the water to help people feel safe and confident, including support for those who needed extra help.
• Swim aids like pool noodles have shown up on this trip for people who want extra reassurance.

Possible drawback to keep in mind: snorkeling quality can vary. One comment flagged that the snorkel masks weren’t perfect for everyone, and not every setup matched the snorkel connection well. If you’re picky about fit, bring your own mask if you travel with one.

The 10-minute hop to Šunj Beach: change of pace on purpose

Between stops you’ll cruise again—about 10 minutes—to reach Šunj Beach. That short run is a breather. You go from cave water to an open-sand setting, so your body gets a reset before the next swim moment.

You’ll also get more deck time for photos of the coast and sea color. It’s one of those “you’ll understand why people come here” segments.

Šunj Beach for an hour: relax, swim, and actually dry off

Šunj Beach is your break: about 1 hour of free time. It’s known in the Dubrovnik area for a calmer feel, with shallow, more forgiving water than the cave zones.

What you can do here:

• Sunbathe and cool off in the sea.
• Walk around and soak up the beach atmosphere.
• Use the included bar service—drinks like cocktails, coffee, and other options come up during this stop.

Why this stop is valuable: it balances the cave intensity. Cave swimming is active, stop-and-start, and often involves short bursts where you’re focused. Šunj lets you shift gears to “slow down” mode—especially if you’ve been in and out of gear and trying to keep track of your swim confidence.

Practical tip: the sun can be intense even with shade on deck. Bring sunscreen and a hat, and plan your swim windows so you’re not just burning time under direct light.

The Blue Cave stop on Koločep: short window, big payoff

The final sea highlight is the Blue Cave on Koločep Island, with about 30 minutes at the location. This is the famous stop—the one people talk about for that glowing blue look and the “how is the water that color?” effect.

How it works in practice:

• You’ll arrive, get time for a photo stop and a visit.
• Swimming/snorkeling is typically part of the experience, and access may depend on water conditions.
• You’ll have a limited window, so it’s best to think of this as a focused moment rather than a long hangout.

One important consideration: water conditions can change what’s possible. There’s at least one clear example of the Blue Cave being more difficult to reach when the sea state wasn’t ideal, so the crew adjusted accordingly. When the skipper changes the route for safety or conditions, the priority is making sure you still get the best possible experience.

If you’re not the strongest swimmer: you can still enjoy the day, but this cave stop may require more comfort in the water than a simple beach swim. Life jackets are provided, and crew assistance is part of the safety culture, but you’ll want to be honest with yourself about your comfort level.

Deck life: toilets/showers, shade, and the drinks that keep it fun

One of the underrated wins on this tour is how comfortable the boat is for a speedboat day. The boat is described as brand new with:

• sunbeds and lounge cushions
• toilets and showers
• sound system and sun protection under a hardtop
• wind and water splash protection

So you can stay comfortable between swim stops without feeling like you’re constantly exposed.

Then there’s the social engine: included alcoholic and non-alcoholic drinks, served throughout the tour. This isn’t just a token beverage. People consistently mention that drinks keep coming and that the crew makes sure everyone has something. Some crews are also described as upbeat and fun, with music helping set the mood.

I like this setup because it removes friction. You’re not tracking money or waiting in line. You’re focusing on enjoying the coast.

Timing and pace: 4 hours that feel full, not rushed

This is a 4-hour tour. It’s short enough to fit into a Dubrovnik itinerary without wrecking your evening plans, but it’s busy enough that you’ll come off the boat feeling like you actually did something.

The pace is built around:

• quick travel segments (25, 10, 15, and 20 minutes)
• one longer cave session (45 minutes)
• a beach break that actually gives time to relax (1 hour)
• shorter but memorable final cave time (about 30 minutes)

For best results, show up thinking this is an active half-day. It’s not a slow sightseeing cruise where you sit for hours and watch. You’re out on the water, and you’ll spend part of the day in swim gear.

Who should book this Dubrovnik speedboat cave tour

This one fits travelers who want:

• an out-on-the-water experience fast
• snorkeling and cave exploration without a full day commitment
• included gear and onboard drinks that keep the day light

It’s less ideal if you:

• have back problems
• use a wheelchair
• are over 60
• are prone to seasickness

If you’re traveling with kids or a group with mixed comfort levels, the crew support can help. Life jackets are provided, and extra swim aids have been mentioned in feedback. Still, the core experience depends on people being okay with ocean swimming.

Group size can vary. One report mentioned a small group around 10 people, which usually means more room to breathe. But you shouldn’t count on a specific headcount—book for the itinerary, not the crowd.

Price and value: $73 for boat, caves, gear, and drinks

At around $73 per person for a 4-hour tour, the value is strongest if you add up what’s actually included:

• new/luxury speedboat transportation
• snorkeling equipment and life jackets
• alcoholic and non-alcoholic drinks during multiple stops
• crew and local skipper
• hotel pickup and drop-off if you select it

If you were booking boat transport separately and renting snorkeling gear separately, the cost can climb quickly. Here, the package keeps you doing the fun parts—water time, caves, beach—without extra line items.

My advice to get the most value: treat it like a swim-focused day. If you skip snorkeling and never get in the water, you lose a lot of the point of the route.

What to bring for cave swimming and beach time

Use the packing list seriously. You’ll be in and out, and you’ll be exposed to sun between stops.

Bring:

• comfortable shoes
• sunglasses and sun hat
• swimwear (plan to wear it underneath if possible)
• towel
• sunscreen
• a waterproof camera (or a waterproof case/phone bag)
• basic camera

Why towels and waterproof storage matter: beach time at Šunj is for relaxing, but cave time can mean wet hands, wet gear, and quick changes. If you don’t protect your phone/camera, you’ll regret it later.

Should you book this Blue Cave + Koločep caves speedboat?

Yes, if you want a classic Dubrovnik sea day with a smart mix of cave exploration and a real beach break. This tour is best for people who enjoy snorkeling or at least comfortable swimming, and who like the idea of drinks and music while the coast slides by.

Skip it (or choose another style of tour) if you’re worried about open-water comfort, seasickness, or rough conditions affecting access. The skipper can change the plan for safety, and the most famous cave stop depends on sea state.

If your goal is to see the coast from the water and get multiple swim moments in just 4 hours, this one makes a lot of sense.
