There’s something about speedboats that makes Croatia feel personal. This small-group outing pairs big-ticket scenery with real water time: you’ll get postcard views of Dubrovnik’s city walls from the sea, then swim in the Blue Cave and finish with free beach time at Šunj on Lopud. I like that it’s active without being exhausting—you’re in the water often, but the crew keeps the day moving. One thing to consider: this is a swim-focused trip, so if you’re not a comfortable swimmer or you get seasick easily, it may not be your best match.

I also like the “kept simple” pacing. You’ll be out about 4 to 5 hours, and drinks are included throughout (local beer, white wine, ice tea, cola, and water, plus Fanta). On boats with hosts such as Ivan and Mario, the vibe is often playful and upbeat, with steady handling and music on the ride. The only drawback I’d flag is crowding at cave stops in peak season, which means you’ll want to be calm and follow crew directions when lots of swimmers share the water.

Key things I’d prioritize on this tour

• Dubrovnik views from the water: city walls and rooftops look dramatically different by boat.
• Blue Cave snorkeling: glowing turquoise light and a short, swim-through style entry.
• Three Green Caves variety: two easier swim-in options plus a narrow passage for the brave.
• Šunj Beach on Lopud: a sandy 1-kilometer stretch with shallow water far out.
• Drinks included all day: beer and wine for the grown-ups, soft drinks for everyone else.
• Crew energy: guides like Ivan, Dora, and Rino are often praised for fun hosting and clear directions.

Dubrovnik City Walls, Sea-Level Views, and Why This Starts With a Ride

The best part of Dubrovnik isn’t just what you see from shore—it’s how high the walls rise above the Adriatic. This tour leaves from Dubrovnik Old Town port (and also offers starts from Cavtat, Mlini, and Srebreno), then you head out by speedboat so the city looks like a fortress floating over the water. It’s fast, scenic, and it sets the mood right away: you’re not waiting around for “the highlight,” because the coastline shows up immediately.

You’ll cruise along the coast and get a pass-by view back near the end, which is a nice touch. A lot of half-day tours in this area rush the sea portion; here, the boat time actually feels useful because you’re constantly reading the coastline—where the cliffs drop, where islands sit close enough to swim, and how the medieval walls dominate the view from below.

One practical note: the captain can change the order of cave stops depending on weather or the sun angle. That’s not a deal-breaker—it usually means you’re getting the most workable conditions for swimming and visibility. When you’re flexible, you tend to have a smoother day on the water.

Entering Koločep’s Blue Cave: Snorkeling Time That Feels Like a Secret

The Blue Cave stop is where the tour earns its name. Located on Koločep Island, it’s accessed by swimming through a narrow entrance, so you’ll want to be mentally ready for a quick “in and out” moment rather than a long, walk-around visit. Once you’re inside, the water and light create that famous turquoise glow, and you’ll understand why people stop here even when they’ve seen photos already.

You get included snorkeling equipment (masks and snorkels). That matters because it turns the stop into real exploring time instead of just looking at the entrance from above. You’ll also have a chance to float and swim around in crystal-clear water, and if you’re comfortable and conditions allow, you can even try cliff-jumping from nearby rocks. (If you’re not a jumper, you’ll still get plenty of swim and snorkel time.)

What to expect during the swim

• Entry is by swimming, not by stepping off a dock.
• Sometimes the approach can include choppier water depending on conditions.
• You’ll want to listen closely at the “how to get in” moment.

In peak season, cave areas can get busy. Even then, the Blue Cave experience still works because you’re not just crowding a viewpoint—you’re in the water, which changes the feel. If you don’t love chaos, stay flexible, keep a steady rhythm, and take your cues from the crew.

Three Green Caves on Koločep: Pick Your Comfort Level

Not long after the Blue Cave, the tour moves to the Three Green Caves, also on Koločep. This is a clever part of the itinerary because it gives different options for different comfort levels. Two of the caves are described as wide and welcoming, which makes snorkeling and floating feel easier. The third is the showpiece for the confident swimmers: a narrow passage that lets you swim through the island and exit on the other side.

That variety is the difference between a “checkbox” cave stop and a real experience. If you’re happy snorkeling, you can choose the more straightforward entrances and enjoy the greenish light and water clarity. If you’re feeling brave, you can aim for the tighter swim-through passage and get that adrenaline boost without needing anything beyond your own swimming ability.

A smart tip for this stop: practice your comfort before you commit to the narrow passage. If you’re unsure, start with the wide cave option first. Once you’ve got your breathing and timing down, you’ll know whether the third cave is for you.

Also, the water can be shared with other boats at this point in the day. That doesn’t mean it’s bad—it means you should keep your head up, keep your mask/gear secure, and don’t rush the entry. The crew handling and timing matter here.

Šunj Beach on Lopud: 1.5 Hours of Sand, Shallow Water, and Easy Unwinding

After all the swimming, the Šunj Beach stop on Lopud Island feels like the exhale. You’ll get about 1.5 hours of free time on a sandy shoreline known for shallow water that stays warm-ish and swim-friendly far out (reported to be shallow nearly 100 meters). That’s perfect if you want to rinse off, float, and settle into the “vacation” mode without constantly fighting waves.

The speedboat anchors close to shore for easier disembarkation. Once you’re on the sand, you can swim again, sunbathe, or simply hang out. There are beach bars, and you can order a refreshing drink at a beachfront bar with blue umbrellas—when you do, a sunbed and umbrella are complimentary. (So you don’t have to choose between relaxing and spending.)

You’ll also find this stop is usually where toilets are available. The general note is that toilets are typically only at Šunj, though sometimes a speedboat with a toilet is available. If this matters to you, it’s worth asking the crew on the day.

Season changes the beach setup. Šunj bars and services begin operating in May. From November through April, the beach stop gets adjusted to Lopud village or Koločep village depending on the day and what’s open. In other words: you can still do the tour off-season, but the “sand-and-shade” experience may swap to village time with open cafés and shops.

Drinks, Music, and the On-Board Comfort That Keeps It Fun

One reason this tour gets repeated praise is the “you don’t have to think about it” drink situation. You’ll have local beer and white wine onboard, plus ice tea, cola, Fanta, and water. The practical value is obvious: after snorkeling and swimming, you’ll actually want cold drinks, and you won’t waste time and money hunting them down.

The boat vibe is also part of the fun. Multiple people describe music on board and a party-like feel on the return ride. Guides such as Ivan and Rino are repeatedly connected to a lively hosting style and good boat energy—so even when the water is doing its thing, the mood doesn’t drop.

What to bring for comfort

• Swimwear (you’ll be in the water early)
• A towel
• If you want phone photos, consider water-friendly protection so you can bring your phone into the cave-water moments safely

One small realism check: this is a speedboat, so hold onto yourself during choppier stretches. The most common complaint isn’t the route—it’s that people underestimate how rough it can feel on open water.

Timing, Group Size, and the “How the Day Feels” Reality

This is set up as a shared small group tour (not private), and the day is built around a straightforward rhythm: ride, swim, ride, swim, beach. Total duration is about 4 to 5 hours, which makes it doable even if you have a busy Dubrovnik schedule.

You’ll do multiple short speedboat segments between stops. The time at the water is also focused: about 30 minutes at Blue Cave and about 30 minutes at the Three Green Caves, plus around 1.5 hours at Šunj Beach. The tour then returns to your starting point, passing near Old Port Dubrovnik.

Group size matters for comfort in crowded water. Some boats are reported at around 14 people, which generally feels manageable for listening to instructions and getting your turn at entrances. If you prefer quiet, this won’t be that kind of outing—but if you like shared energy and you don’t mind a bit of boat-to-boat activity around the caves, it feels lively in a good way.

Weather affects everything here, especially the first cave stop. The captain can adjust order if conditions aren’t ideal. If you’re the type who likes control, just remember that you’re in a dynamic coastal environment, and the crew’s flexibility is part of why the tour stays on.

Safety and Suitability: Who This Trip Fits Best

Safety here is not just “lifejackets on.” Lifejackets (PFDs) are available, but they’re not a substitute for swimming ability. Basic swimming skills are required, including the ability to enter the water, resurface, float, turn, and swim to safety. Noodle floaters are also available if you want extra support.

This tour also isn’t meant for everyone:

• people with back problems
• wheelchair users
• non-swimmers
• people prone to seasickness
• people over 80

That isn’t meant to discourage you—it’s meant to keep the day enjoyable for everyone. Speedboat entry and cave swimming have real physical demands, even if you’re only in the water for short windows.

If you’re worried about motion sickness, plan for it. Choose a time when you can handle waves best, and consider bringing medication if you know you need it. Even then, if you’re highly sensitive, you’ll probably feel it on a speedboat ride.

My bottom-line safety advice: be honest about your comfort level. If you can swim confidently and you’re okay with narrow cave entry by swimming, you’ll likely have a great time.

Price and Value at About $71: Included Access, Not Just Views

At around $71 per person for a 4 to 5 hour outing, this tour isn’t just paying for a scenic boat ride. You’re paying for access to cave swimming spots that would be hard and time-consuming to manage on your own, plus snorkeling gear (masks and snorkels) and a meaningful amount of included drinks.

Lunch is not included. So if you’re the type who eats a lot on vacation, you’ll probably buy something on or near the beach during your Šunj Beach free time. The value still works because you’re not spending that money to replace water access—you’re buying food after you’ve already gotten the swimming and the major sightseeing.

Where the price feels justified is the combination:

• guided handling and timing between stops
• included snorkeling equipment
• repeated water time, not one quick swim
• drinks included throughout the day

If you’re the kind of traveler who hates adding up small extras, you’ll like this setup. You’re already covered for the main extras that usually pop up on island tours.

Should You Book the Dubrovnik Blue Cave and Šunj Speedboat Tour?

Book it if you want a half-day that mixes big-sea views with hands-on swimming: Blue Cave, Three Green Caves, and then sand time at Šunj. It’s a strong pick for active couples and friends, and for solo travelers who are comfortable sharing a boat and joining a small group energy.

Skip it (or choose a different day plan) if you’re a non-swimmer, you get seasick easily, or you don’t want to deal with narrow cave entry and shared water conditions. It’s also a tough fit for people with back issues.

If you can swim and you’re excited by cave snorkeling and a real beach payoff at the end, this is one of the more efficient ways to experience the islands around Dubrovnik in just a few hours.
