Dia Island feels custom-made for a luxury day at sea.

On EOS Yachts’ Heraklion luxury catamaran run to Dia Island, I like the smooth, modern feel from the moment you step aboard, and I especially like that the food is chef-cooked onboard instead of buffet vibes.

Next up: you get a full menu of choices for how you want to spend your time. The included water gear (snorkeling, SUP, canoe boards, fishing gear, plus inflatables) means you can go active or just drift and take photos—then do it again after lunch while the boat stays put in a calm bay.

One thing to think about: this is a semi-private trip with a maximum of 22 people, so it’s not a total buy-the-whole-boat situation. Also, on days with rougher conditions, you might find some water fun is less relaxed than on perfect-glass seas.

Key Things You’ll Notice on This Dia Island Cruise

• Modern, well-maintained catamaran feel that’s designed for comfort (including W.C. for men and women plus a shower).
• Chef-made Mediterranean menu onboard, with seafood plus meat and vegetarian options.
• Dia Island time in a boat-access-only bay, built around swimming and snorkeling.
• A true activity mix: snorkeling gear, swimming vests, fishing gear, SUP, canoe boards, and inflatable sea toys.
• Open bar included (local white wine, beer, soft drinks, and water) to match the full meal plan.
• Captain and crew professionalism, with Captain Thanasis and the onboard chef repeatedly highlighted in feedback.

Meeting at Marina Café: how the day starts smoothly

Your cruise begins in Heraklion Port at the entrance of Marina Café. A crew member will meet you there, guide you to the boat, and get check-in moving.

This matters more than you’d think. The schedule is tight, and the cruise departs exactly on time, so I’d treat that 15-minute early arrival as non-negotiable. Once you’re on board, you’ll start with welcome touches—local Cretan treats plus coffee—then a short safety briefing that keeps things calm without dragging.

If you’re the type who likes to know where you’re going, you’ll appreciate how quickly the staff gets everyone oriented, especially on a catamaran where moving around the deck is part of the fun.

Rocca a Mare (Koules area) photo stop: quick sights, then out to sea

Before you settle into the Dia Island plan, you’ll have a brief port-side moment with a fortress photo stop at Rocca a Mare / the Koules Fortress area. It’s short—just enough time to grab a few photos and orient yourself to the coastline.

Then the catamaran cruise phase begins. Think of this as your decompression period: you’re underway, the sea starts opening up around you, and you’re not yet “stuck” in swim-mode. This early timing helps because Dia Island’s best moments happen once you’re anchored in that calm bay.

Practical note: if you get motion sensitivity, this is when I’d stay near the most stable parts of the boat and keep your focus on the horizon.

The 5.5-hour Dia Island focus: swimming in a myth-shaped bay

Dia Island is the main character. The experience is built around getting you to a place that feels remote but is reachable by boat: hidden bays that aren’t accessible by land.

You’ll spend about 3.25 hours at Dia Island, and the structure of that time is what makes it enjoyable:

• First: swim and snorkel while the light is good and the water is fresh-feeling.
• Middle: switch activities (SUP or canoe board if you want motion; fishing gear if you want to slow down).
• Later: go back in again after lunch, when you’re full and ready for round two.

Dia is tied to myth and legend—there’s a local story that Zeus had something to do with its shaping. You don’t need to be a mythology expert to enjoy that vibe. The real payoff is visual: bright water, steep tones of blue, and that “we’re anchored in a postcard” feeling.

What you can do once anchored

This isn’t one of those trips where you get a single, short swim. The included gear is meant to keep you busy:

• Snorkeling gear plus swimming vests
• Stand-up paddleboards (SUP) equipment
• Canoe board equipment
• Fishing gear
• Inflatable sea toys and swimming noodles

On request, sea scooters are available, but they require advance booking and follow priority order. If this is a must-do, don’t treat it as a last-minute add-on.

Wildlife spotting: dolphins and seabirds

There’s a good chance to see wildlife on the journey—especially dolphins and seabirds. I’d keep your phone ready, but also do the simple thing: look up and scan the water. The best sightings often happen before you remember to switch from photo mode to just watching.

Lunch onboard: chef-cooked Mediterranean flavors, not boat-food compromises

The meal plan is one of the biggest value drivers here. On board, you’ll get:

• Welcome platters with assorted cheeses and cold cuts
• A premium Mediterranean seafood menu, freshly prepared onboard
• Seasonal fruits and local dessert
• Raki as part of the finish
• An open bar with unlimited water, soft drinks, local white wine, and beer

What I like is that you’re not stuck with one “boat version” of a meal. There are meat and vegetarian options, and the menu is designed as a real onboard dining experience.

The chefs get credit for timing and flavor even with the reality of cooking at sea. In feedback, people specifically mention standout dishes like seafood risotto and Greek-style preparations, plus a more comforting meat option served as a hearty baked-style dish. That’s a big deal on a cruise, because the kitchen constraints usually show up in weaker tours.

Drinks included: why it changes the vibe

If you’re used to day trips where drinks feel like an afterthought, this is different. The open bar runs alongside the whole experience, so you can pair a glass of local white wine with lunch and dessert without doing mental math.

Is it a full cocktail bar? Not exactly. Cocktails are not included, but there’s an open bar and the focus stays on easy, included drinks.

The afternoon flow: activities, resting, and a second chance to swim

After lunch, you won’t feel like the day is “over.” Instead, there’s another stretch of downtime where you can go back to the water.

This is where the catamaran format shines. You’re not hiking to a beach, not waiting for a shuttle, and not losing half the day to transit. You swim, you snack, you switch activities, and you rest in between—then you do it again.

If conditions change, the crew keeps the mood steady. Some trips run on perfect calm water; on less friendly sea states, you might see fewer people fully commit to every water toy. But the overall plan stays centered on swimming and snorkeling time, supported by the gear and steady crew attention.

Sailing back to Heraklion: sunset views that feel earned

The return leg is about one hour back toward Heraklion, with views across the Aegean Sea. This timing is set up for golden-hour effects—especially if you’re on board when the light turns softer near late afternoon.

If you’re the kind of person who takes photos “only when it’s worth it,” this is one of those rides where it usually is. The scenery looks different from deck level than from shore, and the catamaran position keeps the horizon feeling open.

You’ll also see the practical side of the boat here. A WC and shower mean you’re not stuck in sand-and-salty misery after the swim portion. And free Wi‑Fi means you can still share the day if you want—though I suspect most people won’t.

Price and value: $141 for what you actually get

At $141 per person for about 5.5 hours, the honest value question is simple: what’s included, and what does it replace?

Here’s what you’re effectively buying:

• A premium catamaran ride (not a basic motorboat shuffle)
• A real chef-prepared lunch with seafood plus meat/vegetarian options
• Welcome snacks and platters
• An open bar for the day (wine, beer, soft drinks, water)
• Snorkeling gear and swimming vests
• SUP, canoe boards, fishing gear
• Inflatables and swimming noodles

So yes, it’s a splurge compared to generic boat trips. But it’s also structured like a full experience: food, drinks, and multiple activity options are included rather than treated as extras.

Two costs to watch:

• Sea scooters cost extra and require advance booking with priority order.
• Private transportation to the port is not included by default (it’s available on request).

Best fit: who this Dia Island cruise works for

This is an easy recommendation if you want your Crete time to feel special without turning it into work. I think it fits best for:

• Couples who want a luxury, relaxed day with swimming and a proper meal
• Families who need a setup that keeps kids (and adults) active with SUP, snorkeling gear, and inflatables
• Food lovers who care that the chef is cooking onboard rather than “reheating something and calling it a day”
• People celebrating something: the crew sometimes arranges birthday surprises like cake when it’s part of the booking setup

It might be less ideal if you’re looking for a long, land-based itinerary with guides talking nonstop about ruins and museums. This cruise is about being on the water and making the sea time count.

Quick packing list and on-board comfort reality check

Keep it simple:

• Swimwear
• Towel
• Sunscreen

Board comfort is part of the ticket price here. You’ll find W.C. (men and women) and a shower, which is a big quality-of-life upgrade when you spend hours in the water.

One more practical note: you’ll likely need to provide identity details for Greek naval regulations—full name, passport or ID number, date of birth, nationality, and gender—during booking or at least one day before departure. That’s normal for Crete port regulations, but it’s better to have it done early.

Should you book Heraklion Luxury Sailing Catamaran Dia Island?

Book it if you want a luxury catamaran day where the main event is Dia Island water time, the meal is genuinely a highlight, and you don’t want to stress about what’s included. The combination of chef-cooked lunch, open bar, and a full activity menu (snorkeling, SUP, canoe boards, fishing gear, and inflatables) makes the price feel more like a package than a ticket.

Skip it only if you’re mainly craving a shore-based sightseeing day, or if you’re traveling with strict expectations about every activity being available no matter the sea conditions. On the water, nature runs the show.

If your goal is an easy, beautiful half-day that looks great in photos and tastes even better at lunch, this is one of the most straightforward ways to do it from Heraklion.
