A floating daybed beats beach hopping. This semi-private catamaran cruise from Hersonissos takes you to Dia Island, an uninhabited Natura 2000 protected area of clear water and simple sea-time. I love that you get proper snorkeling gear plus SUP boards, so you can switch between active and just floating without hunting for equipment.

Food and drinks are a big part of the appeal. You’ll enjoy a nutritionist-style light brunch and a Mediterranean lunch onboard, with unlimited drinks including wine, beer, coffee, tea, and soft drinks.

The one downside to plan around: towels and sunscreen are not included, and private cabins are only on request (not guaranteed).

Key points you’ll actually care about

• Dia Island is protected and uninhabited, so your swim stops feel calm and less crowded than most.
• Snorkeling masks and fins, plus SUP boards are included, which makes the whole day easier.
• Unlimited drinks with a true onboard meal helps this feel like full value, not just a boat ride.
• A professional English-speaking crew, including names you may hear like Captain Alex, can make the experience smooth for families.
• Kid-friendly extras by request, like toys, floaties, and the inflatable pink flamingo, help keep everyone engaged.
• Small group (max 20) on a modern catamaran means you spend less time waiting around.

Why Dia Island feels different than most Crete day trips

Most boat days in Crete follow the same formula: you sail, you stop, you take pictures, you return. Dia Island is different because it’s uninhabited and protected under the Natura 2000 framework, which means the focus stays on the water, the coastline, and respectful use of the area rather than heavy development.

You’ll sail from Hersonissos in the morning and spend time around Dia Island with plenty of room to spread out onboard. That matters. When the group is small and the boat has sunbeds and shaded lounges, you can actually enjoy the pace instead of feeling packed in.

Then there’s the story angle. Dia Island is tied to legend about Zeus shaping the land. You don’t need to be a mythology person to enjoy that detail. It just gives the stop a sense of place, like you’re floating around a real spot with a long cultural thread.

The catamaran setup: sunbeds, shade, and water gear that gets used

This cruise is built for comfort, not just motion. The catamaran has sunbeds and shaded lounges, plus an onboard WC and an outdoor shower. That last part sounds small until you’re out on the water, warm, and ready for a quick rinse.

The water-time equipment is a big deal for value. You’ll get:

• snorkeling gear (high-quality masks and fins)
• stand-up paddleboards (SUP)
• swimming jackets and inflatable noodles for easier, comfy floating
• an inflatable flamingo (pink, for fun)
• fishing gear for a gentle try at fishing

A lot of boat tours say they include activities. Here, the equipment is actually listed and included, not just promised. That means less scrambling, less rental hassle, and more time doing what you came for.

Also, the boat has music and free Wi-Fi onboard. You likely won’t need it all day, but it helps if you want to check messages, update photos, or just keep the mood steady while you’re cruising.

The onboard food and drinks: brunch, lunch, and unlimited refills

If you’re worried a day cruise will be light on food or heavy on filler, this one is designed to feel like a real meal day. The morning starts with welcome drinks like espresso, detox water, teas, and protein cocktails.

Then you get a light healthy brunch and a Mediterranean lunch onboard, made from fresh ingredients from a local Cretan farm. The wording emphasizes organic and farm-sourced ingredients, and the structure matters: you eat like a person, not like you’re grazing between stops.

A nutritionist designed the brunch and lunch approach. Practically, that often means balanced portions and foods that travel well on a boat. It doesn’t mean you’ll only eat leaves and health water. The lunch is described as Mediterranean, and it’s served as part of the onboard day rather than a quick snack.

Vegetarian and children’s options are available on request. That’s the kind of detail that helps families avoid that awkward moment of realizing your kid will only eat bread and regret.

Drinks are also handled like a true all-inclusive day, within the limits of the open bar. Unlimited drinks include:

• water
• soft drinks
• local beer
• white wine
• coffee and tea

One caution: cocktails and alcoholic beverages beyond the open bar selection are not included. If you’re a cocktail person, you might plan to stick to wine or beer included in the selection, or budget a little extra for specialty drinks.

What happens during the sailing day from Hersonissos to Dia

You’re looking at about 6 hours 30 minutes on the water. The start time is 9:00 am, and the tour returns to the same meeting point.

A typical flow goes like this:

1. Morning departure from Hersonissos, with welcome drinks and time to get settled.
2. Cruise toward Dia Island, when you can lounge, swim a little if conditions allow, and get comfortable on the boat’s sunbeds and shaded areas.
3. Dia Island time, the heart of the day, where you’ll have the chance to snorkel, try SUP, and enjoy float breaks.
4. Onboard lunch, served during the day while you’re still out on the water.
5. Relaxed sail back, with snacks and unlimited drinks keeping the mood easy.

The exact order of every minute isn’t something you can control, because sea conditions matter. But the structure is clear: you’re not rushing straight to food or straight to a single swim and done. You get the rhythm of a full day.

And Dia Island being uninhabited helps the experience feel more like real sea time. You’re not sharing the space with a lot of hotels and beach traffic. You’re sharing it with water, light, and a small group on a catamaran.

Snorkeling and SUP: the included activities that make the cruise worth it

Here’s how I’d think about the included activities: they’re not add-ons. They’re part of the day’s value.

Snorkeling gear inclusion is key. A good mask and fins make a noticeable difference compared to cheap rentals. With high-quality masks and fins included, you’re set up to actually enjoy your swim instead of fighting gear.

SUP boards are also included, which changes the experience. A lot of boat days have snorkeling, but fewer include SUP. With SUP, you can:

• paddle along at your own pace
• take a calmer look around the water than you get from snorkeling
• bring your kids along if they can handle the board safely

If you want low-effort fun, the float options help. Swimming jackets, inflatable noodles, and the inflatable flamingo give you ways to enjoy the water without needing to be a strong swimmer.

Fishing gear is included too, and it’s described as a gentle fishing experience. That’s a nice option if you want something to do without committing to a long shore stop.

Practical note: if you’re prone to motion sickness, your best chance is to grab a spot that’s stable and positioned where you feel less rocking. That’s not a tour-specific tip, it’s just sea reality.

The crew and family vibe, with Captain Alex and Annais in the mix

A great crew makes or breaks a day like this. The onboard staffing is described as professional and English-speaking, and the vibe comes through in the experience design: refreshments are offered throughout, and the day is run in an organized way so you’re not constantly trying to figure out what’s next.

You might hear names like Captain Alex and Aleksandr, plus Annais the cook. Crew friendliness isn’t just a nice touch here. When you’re traveling with kids, or when different people want different levels of activity, a calm and helpful crew keeps the day flowing.

For example, toys for kids are available by request. That’s not just a cute extra. It signals that the company expects families to book and wants to reduce boredom between swims and meals.

If you’re traveling as a couple or with friends, the same crew focus helps too. It means fewer interruptions and less downtime. The day stays smooth, and you can keep enjoying the water and the onboard food.

Price and value: what you get for $174.03 per person

At $174.03 per person, this is not a bargain-bin boat ride. But it’s also not overpriced in the way that some “all-inclusive” tours feel, because the inclusions are substantial for a 6.5-hour day.

You’re paying for:

• a modern luxury catamaran experience
• professional English-speaking crew
• snorkeling masks and fins
• SUP boards
• swimming jackets and inflatable float options, including the flamingo
• fishing gear for a gentle try
• onboard brunch and Mediterranean lunch
• welcome drinks plus unlimited drinks (within the open bar selection)
• music and free Wi-Fi onboard
• onboard WC and outdoor shower

When you add it up, the value comes from not having to rent or purchase the core day elements. If you tried to build this yourself, the costs for boat access plus equipment plus lunch and drinks would usually creep up fast.

The only part to watch is drinks beyond the included selection. If you want cocktails specifically, you’ll have to pay extra for anything outside the open bar list.

Who this cruise fits best, and who might prefer something else

This works well for most kinds of travelers:

• Families with kids, because there are float options, kid toys available by request, and a crew that helps keep the day comfortable.
• Couples and friends, because you get plenty of lounging time plus water activities without feeling like you’re on a tight schedule.
• Swimmers and snorkelers, because the gear is included and Dia Island time is the point.

It might not be the perfect choice if you’re chasing a super-immersive, long shore exploration. This is a boat day, not a hiking or sightseeing marathon. The highlight is the sea experience plus the onboard comfort.

Before you go: packing tips and small choices that help

Since towels and sunscreen are not included, pack those. Also bring your own personal care items.

If you want a private cabin, know that it’s on request and not guaranteed. If privacy matters to you, consider planning your expectations around shared lounging and sunbeds. In a day like this, the outdoor and deck spaces can actually be the best part.

You’ll also start at DanEri Yachts in Limenas Chersonisou, at Agias Paraskevis 125 (meeting point). The meeting location is near public transportation, which is useful if you don’t want to rely on a private car.

Finally, dress for sun and sea. Even with shaded lounges, you’ll spend hours outside.

Should you book this Dia Island catamaran cruise?

I think you should book it if you want an easy, all-inclusive day on the water where the core activities are handled for you. Dia Island time plus included snorkeling and SUP makes it feel like more than a simple sightseeing cruise. Add lunch, unlimited drinks, and a small group size, and it becomes a solid “spend a day well” choice.

Skip it if you mainly want shore time, or if you’re hoping for cocktails beyond the open bar selection. Also, if you dislike packing basic essentials like towels and sunscreen, factor that in.

If you’re on the fence and you’re traveling as a couple, with friends, or with kids, this is the kind of day that tends to land well. You get comfort, you get water toys, and you get a meal that feels like part of the trip, not an afterthought.
