A private boat day on the Saronic Gulf.

What makes this trip fun is the mix of real swimming time with island views you can’t really get from shore. I love that the itinerary is built around calm anchorages and short hops between spots, so the day feels relaxed instead of rushed. I also love the “you’re in charge” feel, with a skipper who shares local knowledge and gives you space to choose between a swim, a snack, or a stretch of walking. One consideration: the price listed per group doesn’t include the fuel surcharge (€450 per booking), so budget for that before you book.

You’ll spend about 9 hours at sea, starting at Agios Kosmas Marina around 10:00am and ending back at the same meeting point. The day is structured into four stops with set time windows, but the vibe is flexible enough that you can tailor the rhythm to your group. This is a smart pick if you want a private charter experience without the stress of planning ports, gear, or swim logistics.

Key highlights you’ll care about

• Atlantis Shipwreck area near Aponisos for a low-effort, high-reward swim/float stop
• Megali Bali bay on Agistri with sheltered conditions for easy swimming
• Perdika lunch time in a hilltop fishing village with classic Cycladic views
• Moni Island’s no-buildings feel plus snorkeling and possible wildlife sightings
• Sea scooters + snorkeling gear included, along with drinks, snacks, and WiFi on board
• Private group for up to 11 so you control the pace with your crew

The Saronic Gulf route that feels smooth, not hectic

This is the kind of private day-trip that works because it’s planned like a “gentle day at sea,” not a sightseeing checklist. You’re not trying to cram five different places into five different feelings—you get time to actually enjoy each stop.

The four anchorages connect the Aponisos / Agistri / Perdika / Moni loop in a way that keeps travel segments reasonable. That matters. When the in-between time is comfortable, you remember the good part: the water, the views, and the moment you decide to jump in instead of just watching other people enjoy it.

Also, you get real skipper input. Expect a captain who explains what you’re seeing and helps you find the best moments for swimming and snorkeling based on the conditions.

Aponisos Island and the Atlantis Shipwreck swim stop

First up is the islet of Dorousa (also called Dorousa), just southwest of Agistri. The boat anchors roughly half a nautical mile opposite Aponisos, and this is where you’ll hear about the infamous Atlantis Shipwreck.

You get about 2 hours 15 minutes here. That’s enough time to do the classic boat-day move: a calm swim, a snorkel check, then a slow return to the yacht to rinse off and reset. Since admission is listed as free for this stop, you’re paying for the boat day itself—no extra ticket hurdles.

What to watch for: a shipwreck area can mean varying underwater conditions. You’ll have snorkeling equipment available, but if you’re not an experienced swimmer, keep it simple—float first, then decide. The best plan is to let your captain point you toward the easiest water entry and the calmer zones.

Angistri’s Megali Bali bay: sheltered swimming with cliffs and greenery

Next, you head to Angistri, where the highlight stop is the Megali Bali beach area in Limenaria. This bay is tucked in and protected by rugged cliffs and dense greenery, and the key detail is that it’s only accessible by boat.

You’ll have about 1 hour 45 minutes at anchor. That shorter window still makes sense here, because the goal is quality over quantity: you’re going to swim, enjoy a wind-protected spot, maybe snorkel, then move on while the day still feels fresh.

The practical advantage is the shelter. When bays protect you from wind, the water tends to be calmer, and that means an easier swim for everyone—kids, non-swimmers, and snorkel pros alike.

Perdika: lunch in a hilltop fishing village with sea views

After swimming time, it’s time for a very Greek break. The boat goes to Perdika, a small fishing village in the Saronic Gulf that’s known for traditional Cycladic architecture built on top of a hill.

You’ll have about 2 hours 30 minutes here—plenty of time to wander a bit, soak up the views, and settle into a seafood lunch. This is also a good stop if you want the day to feel balanced. After all the saltwater time, you can take a slow walk and give your body a break from the heat and wind.

The “consideration” at this stop is simple: lunch spots are part of the experience, but your best results come when you arrive hungry and ready to choose. If your group has mixed tastes, tell the skipper early what works for everyone and plan your meal around that.

Moni Island beach: snorkeling, still water, and wildlife you might see

In the afternoon, the itinerary turns toward Moni Island, located next to Aegina. The standout here is that Moni has no permanent residents and no buildings, so the feel is pure nature—clean beaches, clear water, and minimal distractions.

You get about 2 hours 30 minutes at this stop. This is your best stretch for slowing down: swim, snorkel, grab a drink, and if you’re up for it, you can also hike around the island. The day is designed so you can recharge instead of constantly moving.

One of the more memorable details is the possible wildlife spotting. The island is described as a place where you might encounter deer, Kri-Kri goats, squirrels, peacocks, and falcons. You shouldn’t expect a safari-style guarantee, but the environment is clearly set up for nature moments if conditions are right.

If you’re bringing snorkel enthusiasm, Moni is the place to use it. Clear water plus unspoiled shoreline makes it easier to enjoy the underwater view without feeling like you’re fighting the conditions.

What’s included on board (and why it changes the value)

This charter isn’t just a boat that moves you between islands. The “included” list is what makes it feel like a full experience.

You’ll have:

• Skipper & crew
• Water toys
• Sea scooters
• Snorkelling equipment
• Alcoholic beverages
• Bottled water
• Snacks and soda/pop
• WiFi on board

Those items matter because they replace the usual extras that add up. A lot of day charters make you bring or rent snorkeling gear and then sell snacks separately. Here, the basics are already covered, so you can focus on using time well—swim, snorkel, and relax.

A personal note on the overall feel: even when the itinerary is set, the onboard setup makes it easy to change your plan on the fly. If you want more water time, you can; if you want to sit with a drink and just watch, you can do that too.

And based on how the crew is described in past trips, you can also expect a professional, calm approach to planning—captains named Apollo and Vasileios/Vasilis show up as examples of communicative, attentive onboard leadership. Not every charter will be identical, but that style is consistent with what this company aims for.

Price and value for a private group up to 11 people

The price is listed as $1,806.17 per group (up to 11) for about 9 hours. That’s a large chunk of money, so you need to think in group math, not per-ticket math.

If you fill most of the boat, you spread the cost and the included services start to look like real value. You’re not only paying for transport—you’re also paying for a skipper and crew, swim gear, and boat-time drinks and snacks. When you factor in sea scooters and snorkelling equipment being included, the experience starts to resemble a premium day you’d otherwise piece together with multiple bookings.

Then there’s the one extra you must plan for: a fuel surcharge of €450 per booking. Since that’s per booking (not per person), the more people in your group, the less it hurts your per-person total.

My practical advice: if you have fewer than about 6 people, ask yourselves whether you want a true private feel or you’d be happier with a smaller group option elsewhere. If you can fill your group closer to 10–11, this looks like a strong way to buy comfort and flexibility in one package.

Timing, meeting point, and how to make the day match your style

The tour starts from Agios Kosmas Marina (Leof. Poseidonos 18, Elliniko, 167 77, Greece) with a listed start time of 10:00am. You end back at the same meeting point.

Here’s a useful flexibility detail: the trip can start whenever you want, but it must finish by 7:00pm. So if you prefer later light for photos, or you need to work around morning plans in Athens, you can likely adjust—just make sure you keep that end-of-day cutoff in mind.

What I’d do to get the best day:

• Tell the skipper what you want most: swimming, snorkeling, a slower walk in Perdika, or hiking on Moni
• Bring a swimsuit-ready plan. You’re at sea for hours, and the best parts happen when you’re willing to hop in
• Use the snorkeling gear early if it’s clear. Later can still be great, but conditions change

Also, this requires good weather. If wind or rougher seas roll in, expect the day’s comfort to shift. The operator states the experience needs decent conditions, and you’ll be offered another date or a full refund if the trip can’t run due to poor weather.

Should you book this private boat day-trip?

Book it if you want a private day that’s built around swimming time, not just photo stops. This is especially worth it when you can split the group cost and when your crew will actually use what’s included—sea scooters, snorkeling gear, and the drinks/snacks onboard.

Skip it (or reconsider) if your group is small and you’re paying the full charter with no room to spread costs, or if your schedule can’t flex around weather. A boat day is happiest when conditions are right, and this one is designed for that.

If you do book, you’ll likely come away remembering the water moments: the sheltered bay at Angistri, the nature-feel at Moni, and that first swim stop near the Atlantis Shipwreck area. It’s a day that feels like you’re borrowing local calm for a while.
