Blue water, fast boats, and cave swims await. This 4-hour outing takes you from Dubrovnik to the Elaphiti Islands for Three Green Caves snorkeling and a Blue Cave swim, plus drinks served on board. I also like the way the stops are paced: enough time in the water, then real downtime on sand instead of constant rushing.

You’ll get a proper boat-day feel—speedboat hops between islands, a skipper’s safety briefing, and snorkeling gear included. I’m especially fond of the small touches that show up in how guides work, like Mark, Erik, Matko, and Anthony keeping the group moving smoothly and making sure everyone knows what to do before the water part.

One consideration: the cave entries can depend on conditions. If Blue Cave access isn’t possible on your date, you may still swim at alternative spots, but it won’t be the exact same experience. Also, this tour expects real comfort in the water—non-swimmers need not apply.

Key takeaways

• Cave time you can actually do: organized swims at Kolocep’s Green Caves and the Blue Cave area.
• Drinks are part of the rhythm: water, white wine, beer, plus Coca Cola and Fanta served at stops.
• Sunj Beach is your reset: 1.5 hours on the sand on Lopud’s coast, with optional lounge-style relaxation (food/drink may be needed).
• Small-group energy: it’s a shared tour, and some departures run with very few passengers.
• Your comfort depends on swimming: you’ll need essential swimming skills, and lifejackets are only available on request.

Speedboat Start: The Elaphiti Islands in One Breathless Stretch

The day starts with a quick speedboat ride out of Dubrovnik’s harbor area. Expect about 15 minutes on the water early on—long enough to feel like you’re leaving the crowds behind, not so long that anyone gets restless. The boat itself is part of the fun: there’s music on board on many departures, and you’ll get a feel for the coastline as the crew works through the day’s route.

If you picked hotel pickup (available in Dubrovnik city area), you’ll be collected and dropped back after the tour. If not, you’ll meet the group at the dock next to the bus station—simple, but you should plan to arrive a few minutes early. One practical tip: if you’re even slightly unsure where the dock is, message the operator on WhatsApp rather than trying to guess on the day.

Safety matters here. Before the swimming starts, you’ll get a briefing from the skipper/crew. And if you’re someone who likes clear instructions (or you’re traveling with friends who want them), this tour tends to be structured in a way that reduces confusion when it’s time to gear up.

Kolocep’s Blue Cave Swim: Crystal Water, Real Conditions

The first big wow moment is Kolocep Island and the Blue Cave area. In calm-to-seasonal conditions, you’re set up for a swim experience that feels almost surreal—clear water, rocks you can see through, and the kind of marine life viewing that makes a snorkeling stop feel like more than a photo break.

What you should know upfront: Blue Cave access can vary by day. Some departures can’t enter the cave itself due to safety and sea conditions. When that happens, guides often switch you to other excellent swimming/snorkeling spots so you still get the signature feeling of the area—caves, color, and that “how is this real?” water clarity. So even if you’re traveling at a time when conditions are a bit unpredictable, you’re not left with just a scenic boat ride.

This is also the part of the trip where seating location can matter if the sea is choppy. One helpful piece of advice from real departures: if you’re sensitive to rough water, sit toward the back of the boat rather than the front.

Three Green Caves on Koločep: Swimming Through Color

After another short speedboat hop (around 10 minutes), you’ll head to the Three Green Caves on Koločep. This stop is the heart of the tour’s snorkeling promise: a natural phenomenon where the water and cave openings create that green glow effect people come for in the first place.

Here’s what makes this stop work for most people: the crew keeps the flow moving, but it’s not a frantic “jump in, out, next!” situation. You should expect guided entry and time to swim and snorkel at your own pace within the group’s schedule. Snorkeling equipment is included, so you don’t need to bring gear. You’ll also likely have a good window for photos and just watching fish and shifting light below the surface.

If you’re traveling in shoulder season, plan for temperature swings. One October departure note: the water can be wonderful, but you’ll want something warm after you get out—at least a light layer or a quick-dry top. (Croatia in autumn can be sunny while still making that post-swim wind feel sharp.)

Sunj Beach (Lopud): Sand Time That Actually Feels Like Vacation

Then comes the part I love most for balance: Šunj Beach. You get about 1.5 hours here, which is long enough to stop thinking about time slots and just enjoy being on a sandy Adriatic shoreline.

This isn’t a “five minutes, move on” stop. You’ll have a proper break to swim in open water again, cool down after cave snorkeling, and stretch out on the beach. There’s also a lot happening around the beach area—your time on Šunj can include sandy shore views, plus access to an area with a botanical garden and a Franciscan monastery, along with restaurants nearby.

Some guests like to spend this window walking a little, not just lying down. If you want a snack, plan on doing it here. One useful reality check: sun loungers can be part of a beach setup, but they may require buying food or drinks on site—so don’t assume you can just claim the “best seat” for free.

This stretch also helps if you went in a bit nervous about the swims. By the time you reach Sunj Beach, your confidence usually catches up with your adrenaline.

Drinks on Board: Included Refreshments Without the Hard Sell

Let’s talk about the drinks, because on this kind of trip they genuinely affect your comfort. One drink at each stop is included, typically water, white wine, beer, and also Coca Cola and Fanta. That’s a simple list, but it’s practical: you can cool off with water, choose something alcoholic if you want, or go non-alcoholic if you prefer.

In the real world, the way drinks are handled can vary slightly by crew. Some skippers are known for keeping refills coming and keeping everyone happy, especially during swim transitions when people are most likely to forget they’re cold and need water. If you have a specific preference (like non-alcohol beer), you should be able to work with the crew, because many guides seem comfortable accommodating requests.

Just don’t treat this like an unlimited party cruise. The trip still has set swim windows and timing between stops. The drinks work best as a complement—something to enjoy while the day’s big moments happen.

Gear, Safety, and the Swimming Skills Requirement

Snorkeling equipment is included, which is a big deal. You don’t need to pack a mask or ask around for rental gear. The crew will also help you understand where to swim and how to manage entry safely.

But the main safety point is not about gear—it’s about you. This tour requires swimming skills, including being able to enter the water, resurface, control breathing, float, turn, and move to safety. If you can’t do that confidently, skip this one and choose something more shore-based.

A lifejacket can be provided on request. It’s there for safety support, not as a substitute for swimming skills. And if you’re prone to seasickness, this speedboat route might be tough; the tour is not designed around motion-sensitive travelers.

Also, logistics on a boat day can be stricter than you expect. Toilets are available only at the sandy beach. So use the toilet before you check in and plan your day around that reality.

What You’ll Actually Want to Pack (and What You Should Skip)

This tour is very “carry less” friendly. You’ll want swimwear and beachwear, and you should bring your own towel because towels are not included. If you’re worried about getting cold after swims, bring a light layer too—especially if you’re traveling outside peak summer.

Don’t bring luggage or large bags. The tour is set up for quick transfers and short boat stops, so extra bulk just makes everything slower and more annoying.

One small but important planning tip: if you’re traveling in a group, agree on who’s responsible for what. In practice, the swimming portion can move fast enough that it’s helpful to have everyone ready with the right clothes and gear before the boat stops.

Guides and the Small-Group Feel That Changes Everything

A big reason this tour earns strong ratings is how consistent the experience feels once you’re on board. Multiple guides are repeatedly mentioned for being fun while staying professional—examples include Mark, Erik, Matko, Anthony, Roko, Dino, James, and Frank.

What I take from that pattern is simple: the best tours here aren’t just about the caves. They’re about how the crew manages the transitions—getting you into the water safely, keeping the timing relaxed enough to enjoy, and still keeping the group organized.

Some departures also run small. One booking listed about 8 participants plus a guide. If your goal is to avoid feeling like you’re in a long school trip line, you’ll likely like this setup.

Who This Tour Fits Best (and Who Should Look Elsewhere)

This is a great choice if you want:

• A half-day water experience with snorkeling you can do
• Time to relax on sandy beach (not just a quick stop)
• Included drinks during a day spent outdoors
• A crew that prioritizes safe swimming and clear instructions

It may be a bad match if you:

• Are a non-swimmer
• Have back problems or mobility impairments
• Use a wheelchair
• Get seasick easily
• Are prone to panic in open water situations

If you’re unsure about your swimming comfort, don’t guess. This is not the kind of tour where you can easily “watch from the boat” for the main events.

Should You Book Dubrovnik Blue Cave & Sunj Beach?

If you want a classic Dubrovnik-area escape that combines cave swimming, crystal water, and a proper sandy break, I think you’ll like this one. The value is strongest because it bundles the essentials—skipper and crew, snorkeling equipment, hotel pickup/drop-off in Dubrovnik city area if you choose it, plus drinks at each stop.

I’d only hold off if you know you’re not comfortable in the water or you’re traveling with someone who struggles with swimming. Also, if Blue Cave entry is your only reason for booking, keep expectations flexible. Conditions can change what’s possible, and you may end up with excellent alternative swims instead of the exact cave penetration you pictured.

If you can swim and you’re ready for a fast, fun boat day, book it. Bring a towel, plan for cooler air after autumn swims, and keep your camera charged for that green-and-blue underwater glow.
