Heraklion Luxury Sailing Catamaran Dia Island | Gourmet Menu
Sea days do not get much tastier. This 5.5-hour cruise from Heraklion to Dia Island pairs a modern catamaran with chef-prepared Mediterranean food, swimming, snorkeling, paddleboarding, and an open bar. I especially like the fresh onboard cooking and the polished, attentive crew, led by Captain Thanasis on many departures. The main thing to consider is the price: at $141 per person, this costs more than a basic boat trip, and rough conditions can limit some water activities.
You meet at Marina Café in Heraklion Port, then sail past the Rocca a Mare Fortress before spending about three hours in a calm bay at Dia. The maximum group of 22 keeps the trip fairly personal without the cost of a private charter. Cocktails and hotel transfers cost extra, but wine, beer, soft drinks, water, snacks, dessert, and the main meal are included.
Key points before you book

- Chef-prepared food is the star: Expect a fresh seafood menu, with chicken, vegetarian, and children’s alternatives available if requested at least one day ahead.
- Dia Island brings the scenery: The boat anchors in a sheltered bay with clear water, open sea views, and an untouched coastline reached only by boat.
- The catamaran feels spacious: Shaded areas, comfortable seating, toilets, a shower, and free Wi-Fi make the day easier than a cramped small-boat outing.
- Water activities are included: Snorkeling gear, swimming vests, fishing equipment, SUP boards, a canoe board, inflatables, and swimming noodles are provided.
- The crew earns high marks: English-speaking certified staff are attentive without making the trip feel stiff or formal.
- Weather still matters: Wind and sea conditions can reduce the available activities, so bring a flexible attitude along with your swimsuit.
Starting at Marina Café in Heraklion Port

The meeting point is the entrance to Marina Café at Heraklion Port. An EOS Yachts crew member meets you there and guides you to the catamaran for check-in, so you are not left hunting around the harbor looking for a boat.
Arrive at least 15 minutes before departure. The boat leaves at the scheduled time, and this is one occasion when being fashionably late means watching your cruise depart without you.
The first welcome includes coffee, local Cretan treats, cake, and savory delicacies. You also receive a short safety briefing before setting off. It is a useful balance: enough information to know where the safety equipment is and how the water activities work, but not a long lecture that delays the fun.
You need to provide each passenger’s full name, passport or ID number, date of birth, nationality, and gender for Greek naval regulations. Have those details ready when booking, or send them at least one day before departure.

Sailing past Koules Fortress

The first sightseeing moment comes almost immediately, as the catamaran passes the Rocca a Mare Fortress, usually called Koules Fortress. This sturdy stone landmark guards the entrance to Heraklion’s old Venetian harbor and gives you a strong city-to-sea opening for the day.
There is a short photo stop of about five minutes, followed by roughly an hour of sailing toward Dia Island. The ride gives you time to settle into the boat, find a sunny or shaded place, and watch Heraklion recede behind you.
The journey is part of the appeal. You are not being rushed from one port to another in a crowded transfer boat. The catamaran gives you room to sit, talk, take photos, and enjoy the Aegean views. Keep an eye on the water for seabirds and, if luck is on your side, dolphins. One passenger described seeing dolphins as a special highlight, but wildlife sightings are never guaranteed.
The catamaran: luxury that matters at sea

The boat is new, clean, and well maintained, with enough space to avoid feeling packed in. The reviews repeatedly praise the generous layout, modern finish, black shades and tents, and comfortable areas for sitting or stretching out.
That shade matters. A five-and-a-half-hour trip under the Cretan sun can become tiring, especially in July and August. The covered areas let you enjoy the view without spending every minute trying to protect your face and shoulders.
There are men’s and women’s toilets, a shower, and free Wi-Fi onboard. The facilities will not turn the catamaran into a hotel, but they remove several common annoyances from a long day at sea. You can rinse off after swimming, change your level of comfort, and stay connected if needed.
The trip is described as semi-private, with no more than 22 people. That is not the same as having the yacht to yourself, but it is a useful middle ground. You receive the social feel of a shared cruise while avoiding the scale of a large excursion vessel. Private charters are also available by arrangement if you need a more personal setup.
Three hours in Dia Island’s sheltered bay

After about an hour at sea, the catamaran anchors in one of Dia’s quiet bays. The island is linked to Greek myth and is said to have been shaped by Zeus. You do not need to be a mythology expert to appreciate the setting. The real attraction is the clear water, rugged shore, and sense of being away from Heraklion’s harbor.
The boat remains the center of the experience. You are not being dropped on a developed beach with rows of sun loungers and snack bars. Instead, you stay aboard while using the water around the catamaran, which makes the day simple and comfortable.
This stop lasts about three hours, so you are not forced to choose between eating and swimming. You can spend time in the water, return for lunch, then go back out for another swim or paddle. That longer stop is one reason the cruise feels more relaxed than a quick sightseeing boat ride.
Bring a towel, swimsuit, and plenty of sunscreen. You should also expect wet steps and surfaces near the water, so keep phones and cameras secure when moving between the deck and sea.

Snorkeling, SUP, canoeing, and fishing

The included equipment gives the Dia stop some variety. You can use snorkeling gear and swimming vests, paddle a stand-up board, try the canoe board, fish from the boat, or simply use the inflatables and swimming noodles.
The snorkeling is best suited to casual exploration rather than a serious underwater expedition. The seabed around Dia has marine life, and the clear water makes it worthwhile to put on a mask even if you only spend a short time looking around.
The SUP and canoe boards offer a more active way to see the bay. You can also choose to do absolutely nothing, which may be the wisest plan after lunch. A good boat day gives you choices, and this one does not demand that you join every activity.
A sea scooter is available only on request and requires advance booking. Priority is given in booking order, so do not assume one will be waiting onboard. It costs extra, unlike the standard snorkeling and paddle equipment.
Weather can change the balance of the day. One departure had fewer activities because of sea conditions, although the crew still took good care of everyone. This is normal for any open-water outing. The catamaran offers comfort, but it cannot negotiate with wind and waves.
The onboard meal is more than standard boat food

The main meal is one of the strongest reasons to pay more for this cruise. A chef prepares fresh Mediterranean food onboard using local ingredients, rather than handing out prepacked sandwiches or a basic buffet.
The seafood menu can include dishes such as a seafood risotto. One especially praised version used Greek kantaifi shrimp, a creative local touch that gives the meal more character than a generic pasta dish. The exact menu can change with the season and supplies.
The standard meal also includes gourmet platters with assorted cheeses and cold cuts, followed by seasonal fruit and a local Cretan dessert. Raki is served as part of the traditional finish.
Food alternatives are available, but you need to request them at least one day before departure. Choices include chicken, vegetarian, and children’s menus. A meat risotto, lasagna-style dish, and moussaka-style preparation have all been served on different trips, but you should confirm your preferred option in advance rather than count on a last-minute change.
The all-inclusive bar covers water, soft drinks, local white wine, and beer. This is a real value point because drinks can add up quickly on a half-day cruise. Cocktails are not included, though they can be requested separately.
Hospitality from Captain Thanasis and the crew

The crew’s service receives almost as much praise as the food. Captain Thanasis is described as friendly, calm, skilled, and good at making people feel part of the day without turning the trip into a forced group party.
Staff regularly offer drinks, answer questions, help with the equipment, and keep an eye on people in the water. The tone sounds attentive rather than formal. That suits this kind of cruise. You want help when you need it, then space to enjoy the sea.
The crew has also handled special occasions thoughtfully. Birthday cakes and small celebrations have been arranged from booking details, including surprises for people who did not make a separate request. If you are celebrating, add the information to your booking so the team has a chance to prepare.
This personal service is particularly valuable on a shared cruise. A boat can be beautiful and the scenery can be perfect, but a distracted crew can spoil the mood. Here, the human side of the experience appears to be a major part of its appeal.
Sailing back toward Heraklion

After lunch and a final swim, the catamaran heads back toward Heraklion. The return takes about an hour, giving you a chance to dry off, order another included drink, and settle into the view.
Late departures may offer a sunset or golden-hour return, and several people singled out the ride back as one of the most memorable parts. Exact light depends on the departure time and season, so do not treat a dramatic sunset as guaranteed. Still, the open Aegean view makes the return pleasant even in ordinary daylight.
The boat arrives back at Marina Café, where the day began. The total duration is about 5.5 hours, including the outbound and return sailing, the brief fortress sightseeing stop, and the three-hour stay near Dia Island.
Is $141 a fair price?

At $141 per person, this is not the cheapest way to reach Dia Island. You can find simpler boat trips with fewer facilities and less food for less money.
The comparison changes once you count what is included. You receive a modern catamaran, certified English-speaking crew, a chef-prepared main meal, snacks, dessert, an open bar with beer and wine, snorkeling equipment, SUP and canoe gear, fishing equipment, inflatables, a shower, toilets, and Wi-Fi.
I consider the price fair for someone who values comfort and food as much as the island stop. The meal alone is a noticeable step above basic excursion catering, and the spacious boat makes a long half-day easier. It also compares well for couples celebrating a birthday or an occasion when a plain transfer boat would feel too ordinary.
The value is weaker if you mainly want a quick swim and do not care about the meal, drinks, or boat facilities. Private transportation is not included, and cocktails cost extra. Hotel pickup can be arranged on request, but it should be treated as an additional service rather than part of the advertised price.
Who should book this Dia Island cruise?
I would suggest this trip to couples, families, small groups, and anyone who wants a polished day on the water without hiring a private yacht. Families benefit from the children’s menu, swimming vests, inflatables, and range of water activities.
It also suits people who are new to sailing and want comfort close at hand. The crew provides safety guidance, the boat has proper facilities, and you can choose between activity and rest.
This is less suited to someone seeking a quiet private charter, a serious sailing lesson, or a guaranteed dolphin sighting. It is also not ideal if your main goal is a long time walking on Dia Island, since the experience centers on the anchored catamaran and the surrounding water.
Book early if you need a sea scooter, a specific alternative meal, or a birthday arrangement. For the smoothest start, arrive 15 minutes early and keep your schedule clear around the fixed departure time. Free cancellation is available up to 24 hours before departure, and you can reserve now and pay later.
Final verdict: a strong choice for a comfortable sea day
I would book the EOS Yachts cruise if you want Dia Island with good food, reliable service, and a boat that feels more like a small floating lounge than a basic excursion vessel.
The strongest reasons are the chef-prepared meal, generous equipment, shaded modern catamaran, and crew attention. The main cautions are the $141 price, extra cost for cocktails and transfers, and the fact that weather can change the water activities.
For a birthday, anniversary, family treat, or final special day in Crete, this is an easy choice. If you only want the lowest-cost way to swim near Dia, choose a simpler boat trip. If you want the whole package and can accept the premium, EOS Yachts offers very good value.
