Picture blue water and no hurry. This small-group catamaran trip from Heraklion delivers a relaxed day at Dia Island with an onboard open bar, fresh Mediterranean food, and plenty of ways to play once you drop anchor.

I especially like the freshly prepared lunch on board and the fact that the crew handles the details so you can just swim, snack, and float. The other big win for me is the activity mix: snorkeling gear, stand-up paddleboards, and pool noodles are there without you having to bring a thing.

One thing to consider: the experience is small on your boat (up to 14), but the Dia beach stop can still mean other boats nearby, so expect a shared cove vibe at times. Also, I’d do a quick once-over of seat clips and the toilet setup when you board, since a few minor maintenance issues have popped up in past trips.

Key Takeaways Before You Go

• Up to 14 people keeps this day from feeling like a cattle call.
• Time at Dia is the heart of it, with hours to swim and use the water toys.
• Food is made onboard, including brunch and a full Mediterranean lunch plus a homemade dessert.
• Unlimited drinks include local beer and white wine, alongside soft drinks and water.
• Comfort extras matter: restrooms, Wi-Fi, sunbeds, and an outdoor shower.
• Activities are bundled in: snorkeling, SUP boards, noodles, and even gentle fishing gear.

A Small-Group Catamaran Day to Día Island

This is the kind of trip that works because it focuses on one place—Dia Island—then turns it into a full day on the water. You sail out from Heraklion in a modern luxury catamaran, find a great spot, and spend the afternoon swimming and playing in the sea around Dia.

What makes it feel premium is the blend of comfort and included stuff. You’re not just “getting a boat ride.” You’re getting a real day at sea: shaded lounges and sunbeds, onboard music, a restroom on board (plus an outdoor shower), and Wi-Fi so you can post photos without sprinting back to shore.

And because the max group size is 14, it’s easier to hear the crew, follow safety instructions, and actually enjoy your own space on deck.

What the 6.5 Hours Actually Feel Like

The tour runs about 6 hours 30 minutes (with the start time at 9:30 am). In practice, it’s a slow, fun progression: you meet at the port, cruise out, then spend the bulk of the day anchored near Dia.

At Dia, you’ll get a longer block of time (about 4 hours) to enjoy the water. That’s enough to do a snorkel session, swim a few laps, try paddleboarding, then still have time to hang out and recover with a drink and lunch.

Expect a typical “sail, stop, play, eat, sail back” rhythm. It’s not a multi-stop itinerary built around constant movement. If that sounds like a relief to you, you’ll probably like this.

Día Beach: Swimming-First, Adventure-Bonus

Dia Island is the point. Once you arrive at the bay, you can swim, jump from the boat, and explore underwater life with the provided snorkeling equipment. This is one of those locations where you’ll likely spend more time in the water than you planned—especially if you’re the type who looks at the sea and thinks, yes, I should probably go in.

Included gear helps you jump straight into it:

• Snorkeling masks and fins (high-quality)
• Swimming jackets (for extra confidence)
• Pool noodles and inflatable float options
• Stand-up paddleboards (SUP)

You can also borrow inflatable items like an inflatable flamingo for pictures. It’s silly in the best way, and it tends to be the kind of “how did we get this on a boat?” memory you’ll still laugh about later.

There’s also fishing gear included for a gentle try—so if you like casual “maybe I’ll catch something” fun, it’s there without extra cost.

The practical catch: Dia is uninhabited, so plan on your time there being about the water and relaxing, not a long village wandering day. If you want to explore on foot, bring proper footwear, since the island isn’t necessarily made for bare feet.

Food and Drinks: Brunch, Mediterranean Lunch, Open Bar

This is one of the biggest reasons people rate it so highly. You get light brunch plus a freshly made Mediterranean lunch onboard, with a homemade dessert. The lunch is timed so you’re eating after you’ve already been swimming—so you don’t feel like you’re turning your holiday into a cafeteria line.

Drink-wise, the open bar is generous within its selection. You’ll have unlimited access to:

• Water
• Soft drinks
• Local beer
• White wine
• Plus coffee/espresso and teas, along with items like detox water and a protein cocktail

A nice detail: there’s music onboard, and the Wi-Fi is available while you’re relaxing on deck. That combination makes lunch and snack breaks feel like part of the day, not just a requirement.

One limitation to note: cocktails and alcoholic drinks beyond the open bar selection aren’t included. If you’re a cocktail person who likes fancy pours, you may want to plan your expectations.

The Boat Setup: Comfort That You Notice Midday

A premium day at sea is mostly about the little comfort wins. Here you get:

• Sunbeds and shaded lounges
• A restroom (onboard WC) plus an outdoor shower
• Life jackets
• Onboard Wi-Fi
• Music
• Plenty of deck time without feeling cramped

Also, you can borrow the gear you need without negotiating rental prices or waiting in a line. That matters because when you’re in vacation mode, you want your “yes” activities to be frictionless.

Private cabins can be requested, but use isn’t guaranteed. If your top priority is total privacy, consider that you’re still booked into a shared deck day. For most people, the open-air lounging space is the real appeal anyway.

One more practical note: at least one past trip included reports of small broken seat clips near knee level and a toilet door lock issue. That doesn’t scream unsafe from what’s provided, but it does suggest it’s worth doing a quick check when you step onboard—then flag it to the crew right away.

Group Size and the Small-Group Promise

With a maximum of 14 travelers, this is designed to feel more personal than the big party boats. In many trips, you end up with a handful of passengers, and it’s easier to get attentive guidance.

That support shows up in the way the crew runs the day. Names like Spiro, George, Sergey, Thomas, and Alexander have been mentioned in past experiences, and guests appreciated clear instructions and friendly hosting.

Just keep one nuance in mind: small group is about what’s on your catamaran, not about the sea behaving like it’s private. At Dia, other boats may be nearby at anchor, and you might hear other music from time to time. If you’re especially noise-sensitive, pick your expectations accordingly.

Price and Value at Around $181.41

At $181.41 per person, you’re paying for three things at once:

1) A modern catamaran and a crew running the day

2) A full onboard food plan (brunch + Mediterranean lunch + dessert)

3) Included water time tools (snorkeling gear, SUP, noodles, and more)

When a boat tour charges extra for snorkeling rentals, food, and alcohol, it adds up fast. Here, the bigger-ticket items are bundled. That’s part of why the overall rating is extremely strong, with 97% recommending it.

That said, value is personal. If your day is only about sailing and you don’t plan to swim or use the included gear, then you may feel less excitement for the price. On the other hand, if you want a prepared lunch on a comfortable deck and you’ll actually use the water toys, it’s likely to feel worth it.

Practical Tips for a Smooth Day at Sea

These are the things that help you enjoy the day without last-minute stress:

• Bring sunscreen and personal care items. Towels and sunscreen aren’t included.
• Plan to wear something you can get wet. The water jackets are there, but your clothes still matter.
• If you think you might explore Dia on foot, pack proper footwear.
• Wear reef-friendly habits if you have them. It’s a sea day, and you’ll be happier if you’re not thinking about your steps.
• Have a light plan for photos. The inflatable flamingo is there for fun shots, but bring your best attitude—gear can’t fix bad timing.

If you’re staying outside Heraklion, budget extra time for getting to the meeting point. This trip starts at Café MarinaLeof. Nearchou, Iraklio 712 02.

Who Should Book This (And Who Might Not)

This catamaran day fits best if you want:

• A relaxed schedule built around one standout stop
• Included food that’s more than snack plates
• Real time in the water (snorkeling, SUP, floaties)
• A smaller group feel without turning it into a private charter price

You might pass if:

• You’re expecting absolute silence and zero boat traffic at anchor
• You only want basic swimming time and won’t use snorkeling or SUP
• You’re very specific about cabin privacy (private cabins are request-only and not guaranteed)

Should You Book the Dia Island Catamaran?

Yes, if your idea of a great Crete day is: sailing out, dropping anchor, then spending hours in clear water with food and drinks taken care of. The combination of small-group size, onboard lunch, and included snorkeling + SUP is what makes this trip consistently satisfying.

I’d especially recommend it to couples, small families, and friend groups who like structure-free fun—swim when you want, eat when you’re hungry, and let the crew handle the rest. Just go in knowing it’s small on your boat, and the cove can still be shared.
