Heraklion: Dia Catamaran Tour – Lunch, Open Bar & Snorkeling

The best part of this Heraklion catamaran cruise is the balance: you get a proper sailing trip, a long swim stop at Dia Island, and a fresh lunch without having to plan any of it yourself. I like the roomy boat, the clean facilities, and the fact that you can spend the day swimming and paddling or simply stretch out in the sun. I also like the family touches, from children’s meals and toys to the inflatable flamingo.

The main consideration is the price, about $141 per person. That is not a cheap beach outing, but it covers five hours, a spacious semi-private boat, food, drinks, equipment, and crew service. The cruise is also weather-dependent, and pregnant travelers should not book it.

Key points at a glance

• Dia Island by catamaran: Sail from Heraklion to a quiet bay with clear water and scenic views.
• A full meal on board: Start with coffee, tea, pies and cheese, then enjoy Mediterranean dishes with seafood, meat, and special options for children.
• Plenty to do in the water: Use the snorkeling and fishing gear, SUP boards, canoe, arm floaties and inflatable toys.
• A comfortable family setup: The boat has shaded and sunny seating, cabins for resting, Wi-Fi, music, toys and life jackets.
• A semi-private feel: The catamaran can accommodate up to 20 people, giving the trip a more personal atmosphere than a large ferry-style excursion.
• Useful pickup options: Transfers can be arranged from many resort areas, although hotel pickup is not included in the standard price.

Why Dia Island is best seen from the water

Dia Island sits off the coast of Heraklion, and the approach is part of the pleasure. From the catamaran, you see the island from the sea rather than arriving at a crowded harbor or following a fixed beach excursion schedule.

The island stop takes about two hours and 45 minutes. That is enough time to swim, try the water equipment, eat lunch, and still have room to slow down. You are not simply stepping ashore for a quick photo. The focus is the bay itself, with clear water, open views, and time to enjoy the sea at your own pace.

I especially like that the cruise does not force every passenger into the same activity. If you want action, you can use the SUP boards, canoe, snorkeling gear or fishing equipment. If you prefer a quiet afternoon, there is space to sit in the sun or shade and watch the children play.

Boarding at Heraklion harbor

Plan to arrive 15 minutes before departure. The meeting point is at the Marina Café, at the tables facing the sea and boats. A crew member wearing a DanEri shirt will meet you there.

Parking is available at the marina for about €5 per day. That small detail matters if you are driving from a resort area and do not arrange a transfer. Pickup and drop-off can be added from places including Heraklion, Ammoudara, Karteros, Kokkini Hani, Gouves, Hersonissos, Malia, Stalida, Agia Pelagia, Lygaria, Sissi and Milatos.

Once aboard, the crew gives a safety briefing and welcomes you with coffee, tea, detox water and fresh pies. A cheese platter is also included. This first 15-minute period is practical as well as pleasant, since it gives you time to settle in, find a seat and learn where the safety equipment is kept.

The crew is Red Cross certified, and life jackets are available. That will reassure parents, especially on a boat carrying children. The trip is also listed as wheelchair accessible, though you should confirm the exact boarding arrangements when booking if anyone in your group needs assistance.

The hour-long sail to Dia

The crossing to Dia takes about an hour. This is not dead time. It is when you can enjoy the boat, get comfortable, and watch the Heraklion coast recede.

The catamaran has broad areas for sitting and relaxing, with both sunny and shaded spots. The front is popular with children who want a little spray and a better view of the water. Adults may prefer the rear or shaded seating, especially during the warmer part of the day.

Free Wi-Fi and selected music are available. Unlimited soft drinks, beer and white wine are served throughout the cruise. The open bar works well here because the trip is long enough to feel like a day out, not simply a short transfer. Still, you will want to pace yourself, especially in the sun and on a moving boat.

The crew may include Captain Joana, Captain Giannis, Gianna and chef Konstantinos, depending on the departure. The service is one of the strongest parts of the experience. Expect help with the equipment, friendly attention, and practical guidance rather than a formal sightseeing lecture.

A long swim stop in Dia’s clear water

The catamaran anchors in one of Dia’s bays for the main part of the day. This is where the trip earns its place on a Crete itinerary.

The water is clear enough for snorkeling, and masks and other equipment are provided. You may see small marine life close to the boat, though the experience is more about enjoying the open water than visiting a major underwater site. Bring your towel and swimwear, and apply sunscreen before boarding.

The SUP boards and canoe add variety. You can paddle around the anchored catamaran, take turns with your family, or simply swim from the boat. Fishing equipment is also available, although the information provided does not promise a catch or a dedicated fishing lesson.

For children, the arm floaties, life jackets, inflatable toys and flamingo make the swimming stop more playful. A box of toys is available on board too. Younger children can stay involved even if they are not ready for snorkeling or paddleboarding.

One practical point: the activity is centered on the sea. If you are looking for a long walk on Dia Island or a guided exploration on land, this is not that kind of excursion. You spend your time around the bay and on the catamaran, with the water as the main attraction.

Lunch on a moving restaurant

Lunch is freshly prepared on board and served during the Dia stop. The meal includes salads, hot dishes, seafood and meat, followed by homemade dessert.

This is more satisfying than the usual sandwich and bottled-water setup found on many boat trips. The menu is designed for a mixed group, with vegetarian, vegan and gluten-free options available when requested in advance. Children have a special meal option, which removes one common source of stress for families.

Chef Konstantinos is specifically praised for the seafood, but the meal is not limited to fish. Meat dishes, salads and hot sides give you a broader choice. If you have a strict dietary need, make the request at booking rather than waiting until boarding.

The open bar includes unlimited soft drinks, white wine and beer. Coffee, tea, detox water and welcome snacks are provided earlier in the morning. Alcohol is available, but the cruise is not built around partying. The mood is closer to a relaxed lunch on the water, with swimming and conversation between courses.

The return sail and the slower final hour

After lunch and the water activities, you have time to dry off, sit back and enjoy the return crossing. The trip includes another hour on the catamaran, so it helps to keep a dry layer or cover-up nearby.

The return route gives you a second chance to enjoy the views without rushing to the next activity. Some departures may catch warm late-day light, and the sunset can be especially attractive on the way back, depending on the timing and season.

Families get a useful bonus here: children who are tired from swimming can rest in the cozy cabins. That makes this a better choice for a full family day than a smaller open boat with nowhere to escape the sun.

The activity ends back at the original meeting point. If you arrange a transfer, the provider can return you to the listed resort areas.

What the $141 price includes

At about $141 per person, this cruise sits above a basic group boat trip. The value depends on how much of the package you will use.

You are paying for:

• Five hours on a spacious sailing catamaran
• A semi-private group setting, with capacity for up to 20 people
• Coffee, tea, detox water, pies and cheese
• A freshly prepared Mediterranean lunch
• Seafood, meat and plant-based meal choices
• Unlimited soft drinks, beer and white wine
• Snorkeling, fishing and swimming equipment
• SUP boards, canoeing gear and inflatables
• Wi-Fi, music, cabins, toys and life jackets
• An experienced crew and liability insurance

If you would otherwise pay separately for a boat trip, lunch, drinks and water equipment, the price becomes easier to justify. The spacious catamaran also matters. A crowded, low-cost boat can make a long day feel tiring, while this setup gives you more room to sit, move around and take a break.

The price is less attractive if you do not drink alcohol, skip lunch, or plan to stay dry. In that case, a simpler harbor cruise may suit you better. For families and groups who want everything organized, the package is stronger value.

Who will enjoy this cruise most

I would recommend it most to families, couples, friends, and anyone who wants a gentle day at sea without arranging each part separately.

It works particularly well for families because the boat provides life jackets, floaties, toys, a children’s meal, cabins and several kinds of water activity. Kids can move between swimming, paddleboarding, the inflatable flamingo and the front deck, while adults can sit in the shade with a drink.

It also suits adults who want a polished outing rather than a bare-bones boat ride. The crew, food and spacious seating give the trip a more special feel, which can work well for a birthday or anniversary. For special occasions, the team provides a complimentary gift.

This is not suitable for pregnant women. It may also be a poor match if you dislike boats, strong sun, or swimming-based activities. The cruise can be rescheduled or canceled in bad weather, so keep some flexibility in your Crete plans.

What to bring and what to arrange early

Bring a towel, sunscreen and swimwear. You also need a passport or ID card, and a copy is accepted.

When booking, provide each passenger’s full name, date of birth, passport or ID number, and nationality. Port authorities require these details before the cruise can receive permission to sail, so this is not paperwork to leave until the last minute.

Request dietary needs in advance, including vegetarian, vegan or gluten-free meals. If you need hotel transport, select the appropriate transfer option or ask about availability before paying. Standard hotel pickup and drop-off are not included.

The trip is offered in English and Greek. Private groups are available if you want a more personal arrangement for your family or friends.

Should you book the Dia catamaran cruise?

Book it if you want one well-organized day that combines sailing, swimming, lunch and drinks. The spacious catamaran, attentive crew, fresh meal and useful family equipment make this more than a simple trip to a beach.

I would be especially comfortable recommending it to families with children, small groups celebrating something, and visitors who want a taste of sailing without committing to a full-day yacht charter. The five-hour length is also sensible: enough time to reach Dia and enjoy the bay, but not so long that the day becomes exhausting.

Skip it if your main goal is a cheap boat ride, a long hike on Dia, or a quiet alcohol-free outing. At $141, you are paying for comfort, service, food and convenience. For the right group, that combination makes the cruise a strong use of one day in Crete.
