Private Boat Day-Trip to Angistri, Aegina and Moni

The best part of this private boat day is the freedom to trade crowded ferry decks for quiet coves and clear water. From Athens, you reach four very different stops in the Saronic Gulf, including the Atlantis Shipwreck near Dorousa and the unbuilt island of Moni.

I like the private format, which lets your group choose a slower swim, a longer lunch, or extra time on shore. I also like the practical touches: sea scooters, snorkeling gear, water toys, snacks, drinks, WiFi, and captains such as Apollo and Vasilis who help shape the day.

The main consideration is price. The listed cost is $1,806.17 for up to 11 people, but a €450 fuel surcharge is extra. That can be sensible for a full group, yet costly for a small party. You also need good weather, and the day must finish by 7 p.m.

Key points to know before you book

• The Atlantis Shipwreck comes first: You spend about 2 hours and 15 minutes near Dorousa, the islet opposite Aponisos, with time for swimming and exploring from the boat.
• Megali Bali is a sheltered swim stop: This small bay near Limenaria on Agistri is protected by cliffs and greenery, and it is reached by boat.
• Perdika gives the day a proper lunch stop: The fishing village has traditional Cycladic-style buildings and seafood restaurants overlooking the water.
• Moni is the quietest stop: With no permanent residents or buildings, it offers swimming, snorkeling, drinks, hiking, and the chance to spot deer, Kri-Kri goats, squirrels, peacocks, and falcons.
• The boat is stocked for a full day: You get water, soft drinks, alcoholic beverages, snacks, snorkeling equipment, sea scooters, water toys, and bottled water.
• The value improves with a large group: The boat is private for up to 11 people, so the per-person cost changes sharply depending on how many join you.

Leaving Athens from Agios Kosmas Marina

The day starts at 10 a.m. at Agios Kosmas Marina, Leof. Poseidonos 18 in Elliniko. This is a southern Athens departure point, not a central city meeting spot, so allow time to reach the marina. The official end point is the same place.

The cruise lasts about nine hours, with the schedule designed to finish by 7 p.m. You can apparently choose a later or earlier starting time, but the day still has to end by 7 p.m. That gives you useful flexibility if your group wants a quieter morning, though a late start means less time at each stop.

This is a private activity, so only your own group participates. That matters more than it might seem. You do not have to fit around strangers during a swim, wait for a large group to reboard, or follow a rigid shore schedule. A private boat also works well for families, couples traveling with friends, and groups with mixed interests.

The boat is described as modern, clean, and well maintained. A family group with three young children found it comfortable, with plush towels, snorkeling equipment, fruit, Greek rosé, soft drinks, and a charcuterie board available during the day. Those details suggest a more polished outing than a basic boat transfer.

Dorousa and the Atlantis Shipwreck

The first stop is described as Aponisos Island, but the actual point of interest is the islet of Dorousa, also spelled Dorousa, about half a nautical mile opposite Aponisos. It belongs administratively to Agistri.

This is where you find the Atlantis Shipwreck. You have about 2 hours and 15 minutes here, making it the longest early stop. The appeal is simple: the wreck gives you something to look at beneath the water, while the surrounding sea provides space for swimming and relaxing away from a built-up beach.

Because this is a boat-access stop, you are not arriving at a conventional beach with a promenade, shops, or changing rooms. Bring your swimsuit under your clothes and use the onboard facilities and equipment. The supplied snorkeling gear should make it easier to look around the wreck, while the sea scooters and water toys offer more active ways to use the stop.

Your skipper’s guidance will matter here. Conditions around a wreck can vary with wind, visibility, and water movement, and the crew can help you decide how much time to spend swimming compared with staying aboard. If some members of your group do not want to enter the water, the boat still gives them a comfortable place to enjoy the view.

One small point needs attention when you book: the stop names can sound confusing. Aponisos, Dorousa, and Agistri are connected in this part of the schedule, but they are not all the same place. Ask the operator to confirm the exact anchorage and what you will see there.

Megali Bali Bay on Agistri

After the shipwreck stop, the boat heads to Agistri and anchors at Megali Bali beach in the Limenaria area. This is a small bay enclosed by rugged cliffs and thick greenery. It can only be reached by boat, which explains why it feels more secluded than an ordinary island beach.

The bay is sheltered from the wind, making it a strong choice for the main swimming portion of the day. If you prefer calm water, this may be one of the most enjoyable stops. You can use the snorkeling equipment, take out a sea scooter, or simply float beside the boat.

You have about 1 hour and 45 minutes here. That is long enough for a proper swim without turning the whole day into one beach stop. I like the balance: the schedule gives you real water time, but still leaves room for a village lunch and a final stop on Moni.

The tradeoff is that the bay is small. You should not expect a wide sandy beach or a full range of facilities. The charm comes from the cliffs, the greenery, and the quiet approach by sea. If your idea of a beach day includes cafés and easy access from land, this stop may feel too spare. If you want a calm place to swim, it fits the trip well.

Lunch and village time in Perdika

Perdika is the shore stop that gives the cruise a more local, human rhythm. This small fishing village sits on a hill above the water and has buildings with a Cycladic look, despite being in the Saronic Gulf rather than the Cyclades.

The schedule allows about 2 hours and 30 minutes here, the same amount of time allotted to Moni. That is generous for lunch. You can sit at a local seafood restaurant, enjoy the views, and take a short walk through the village instead of rushing back to the boat.

The village is presented as the ideal place for seafood, but lunch is not included in the listed package. Plan for that extra expense. The crew can help organize a restaurant reservation, and one family particularly valued having lunch arranged at a good spot with a view. Still, ask in advance whether your preferred restaurant and meal are included in the planning, or whether you will pay the restaurant directly.

Perdika also gives you a break from swimming. That matters on a nine-hour boat day. You can dry off, eat properly, stretch your legs, and see a working fishing village before returning to the water.

The setting is scenic, but do not treat this as a major sightseeing tour. The attraction is the combination of a small harbor, hillside views, seafood, and traditional architecture. If your group includes people who want more shore time, Perdika is the stop most likely to satisfy them.

Moni Island in the afternoon

Moni is the final stop, next to Aegina. It has no permanent residents and no buildings, so the mood is different from Perdika and Agistri. This is a natural stop rather than a village visit.

The island is known here for clear water, unspoiled beaches, and snorkeling. You have about 2 hours and 30 minutes, giving you enough time to swim, use the water toys, have a drink, or walk on shore. The wildlife is part of the attraction. You might see deer, Kri-Kri goats, squirrels, peacocks, and falcons.

Do not assume every animal will appear on every visit. Wildlife is unpredictable, and the point is the chance to see it in an undeveloped setting. Keep food and personal belongings secure, and follow the crew’s advice around animals.

Moni is also the best stop for a group that cannot agree on one activity. Swimmers can stay near the boat, confident snorkelers can explore the water, and others can walk or sit with a drink. The lack of buildings is a benefit if you want peace, but a drawback if you need shops, shade structures, or a proper café.

Because Moni comes late in the day, it also works as a relaxing finish. After lunch in Perdika, you can spend the final stretch in the water or on the beach rather than fitting in another formal attraction.

What comes onboard for your group

The package includes a skipper and crew, bottled water, soft drinks, alcoholic beverages, snacks, WiFi, snorkeling equipment, sea scooters, and other water toys. The equipment makes the tour feel like a full day on the water rather than a simple charter between four points.

The onboard food is worth clarifying before departure. The package lists snacks, but individual arrangements can vary. The supplied experience includes examples of cut fruit, a charcuterie board, Greek rosé, and drinks for children, yet you should confirm what will be prepared for your booking and tell the operator about dietary needs.

The same applies to lunch. The restaurant meal in Perdika is not listed as included, even though the crew can assist with arrangements. Budget for lunch separately unless your booking confirmation says otherwise.

The crew’s role is another strength. Apollo is praised for being polite and professional, while Vasilis or Vasileios is associated with careful itinerary planning, lunch arrangements, and transfer help. The most useful style of guiding here is light-touch: enough information to explain the islands, but enough space for your group to enjoy itself.

One family also received hotel pickup and drop-off. The stated meeting point, however, is Agios Kosmas Marina, so do not count on a private transfer unless it is confirmed in advance. Treat that as a possible arrangement, not a standard inclusion.

Is $1,806.17 plus fuel a fair price?

The base price is $1,806.17 per group of up to 11 people, with a separate €450 fuel surcharge per booking. That means your real cost is higher than the headline figure, and currency exchange rates will affect the final amount.

For 11 people, the base price works out to about $164 per person before the fuel surcharge. Split the €450 fuel fee evenly, and the total remains easier to justify for a full group. For five people, the same boat becomes much more expensive per person. For two people, this is a luxury splurge rather than a value outing.

The price includes a private boat, crew, a full day, several swimming locations, onboard drinks and snacks, and activity equipment. It also buys control over the pace. If you value privacy and do not want to spend the day on scheduled ferries, the cost can make sense.

It is less compelling if your main goal is simply to reach Aegina or Agistri. Public ferries are a different kind of trip and will cost far less, though they cannot offer private coves, a custom route, onboard equipment, or a captain focused only on your group.

Ask for the total price in writing before paying. Confirm the €450 fuel surcharge, lunch arrangements, transfer requests, the boat model, and what food and drinks will be available. Those questions prevent the most likely surprises.

Who will enjoy this private cruise?

I would recommend it most for a group of six to 11 people that wants a relaxed day outside Athens without planning every ferry, taxi, beach, and restaurant separately. Families can benefit from the private space and flexible timing, especially since water toys, towels, snacks, and drinks are available.

It also suits friends who want a social day with swimming and wine, couples traveling with another couple, and anyone who prefers quiet coves to busy public beaches. The route gives you a good mix of water, a village, seafood, wildlife, and boat views.

You should think twice if you dislike being on a boat for long periods, need a guaranteed sandy beach, want extensive archaeological sightseeing, or are working with a tight budget. This is not a ruins-focused Aegina tour, and the day includes substantial time aboard.

The tour requires good weather. If poor conditions force cancellation, you are offered another date or a full refund. You can cancel for a full refund up to 24 hours before the start time, but changes made inside that window are not accepted.

Final decision: book it for the right group

Book this cruise if you can fill much of the boat and want a private, flexible day built around swimming. The strongest reasons are the Atlantis Shipwreck, the sheltered Megali Bali stop, a proper seafood lunch in Perdika, and the unbuilt shoreline of Moni.

I would not book it blindly for a small group. First confirm the total cost with fuel, the exact boat, lunch plans, and whether pickup is available from your hotel. If those details fit your budget, this is a well-rounded way to see the Saronic Gulf without spending the day following a crowd.
