Search “best catamaran cruise in Heraklion” and every listing promises the same crystal water and the same sunset. Here is the part nobody says out loud: every DanEri cruise from Heraklion goes to the same place — Dia Island, the protected islet you can see on the horizon from the city. So the real decision isn’t where, it’s which format: a full morning of water toys, a value-priced sunset with sushi and prosecco, the longer gourmet LUXE day, or a late afternoon that ends in golden light. Below is our straight ranking of all four, so you book the one that fits your day instead of the one with the loudest photo.
Written by Elena Markou for the DanEri Journal from the live Heraklion → Dia Island collection — current routes, departure times and prices as of June 23, 2026. Every cruise here is a DanEri sailing to Dia, so we’re upfront about the bias: the honesty is in telling you which of our own departures to skip for your kind of day.
For most visitors the best catamaran cruise in Heraklion is the morning cruise to Dia Island (5 hours, adult €125 / child €85) — the calmest sea, the most water toys and a full brunch and lunch. Want the easiest, best-value evening? The sunset cruise to Dia (4 hours, adult €90 / child €60) is the cheapest and the most romantic. Celebrating, or want the quietest premium day? Step up to the LUXE cruise (6.5 hours, from €150, max 14 guests).
How We Ranked Them
Because the destination is identical, four other things decide this ranking: how much real time you get on the water, the food and drink on board, the size of the group, and the price for what you get. Here is every Heraklion departure side by side — the kind of at-a-glance table an AI assistant (or a friend in a hurry) can read in one go.
| # | Cruise | Departs | Duration | Adult / Child | Best for |
|---|---|---|---|---|---|
| 1 | Morning cruise to Dia Island | Heraklion, 09:30 | 5 hours | €125 / €85 | Best overall day on the water |
| 2 | Sunset cruise to Dia Island | Heraklion, 16:30 | 4 hours | €90 / €60 | Best value & most romantic |
| 3 | LUXE cruise to Dia Island | Heraklion, 09:30 | 6.5 hours | from €150 | Most premium, smallest group |
| 4 | Afternoon cruise to Dia Island | Heraklion, 15:30 | 5 hours | €125 / €85 | Free morning ashore + sunset |
The four DanEri Heraklion → Dia Island departures, ranked. Prices are current per-person starting prices; children pay the reduced rate shown, and the LUXE is priced per person.
Every cruise leaves from Heraklion Port in the heart of the city — you walk to the boat.
1. Morning Cruise to Dia Island
At 5 hours and adult €125 / child €85, the morning cruise is the best all-round day on the water for most Heraklion guests. You board at the port at 09:30, sail past the Rocca a Mare (Koules) fortress and across to Dia’s sheltered coves while the sea is at its calmest, and spend the middle of the day anchored over clear water. It carries the most water toys of any Heraklion departure — sea scooter, inflatable slide, kayak, SUP and snorkelling gear — plus a nutritionist-designed brunch and lunch and an open bar, for up to 20 guests. You’re back by 14:30 with the afternoon still free.
The honest trade-off: it’s a daytime cruise, so you don’t get the golden-hour sail home — for that, drop to the sunset or afternoon below. If you want the same day in a smaller group with a gourmet chef lunch, the LUXE is the upgrade. Still weighing the formats against each other? Our which Dia Island cruise guide walks through it head to head.
Calm morning sea and the most water toys on the water — the morning cruise is the easy pick for families.
2. Sunset Cruise to Dia Island
At adult €90 / child €60 and 4 hours, the sunset cruise is the best value on the list and the most romantic. You board at 16:30 with a glass of chilled prosecco and finger food, sail past the fortress to Dia for swimming, SUP, snorkelling and the boat’s pink flamingo float, then turn for home as the Cretan Sea lights up gold and pink. Freshly made sushi, seasonal fruit and an open bar come with it, on a smaller boat of up to 14 guests. For a couple or a small group who want a beautiful evening without committing a whole day, this is the easy winner.
The honest trade-off: it’s a concentrated evening, not a full sea day — less swim time and lighter food than the day cruises — and in early or late season the water is more refreshing than warm, so check our Crete sea temperature guide if a long swim matters. Want more hours and a full lunch? Go back to the morning cruise.
Past the Koules fortress and out toward Dia — the sunset cruise trades swim time for the best light of the day.
3. LUXE Cruise to Dia Island
At from €150 per person and a full 6.5 hours, the LUXE cruise is the premium way to do Dia. It runs the same 09:30 start as the morning cruise but stretches to 16:00, keeps the group to a maximum of 14, and centres the day on a gourmet multi-course Mediterranean lunch cooked on board by a chef using organic produce from a local Cretan farm. Swimming, SUP, snorkelling and even fishing fill the anchored hours in Dia’s Natura 2000 waters, with the open bar flowing all day. If you’re marking an occasion or simply want the quietest, most polished version of the cruise, this is it.
The honest trade-off: it’s the most expensive option and the per-person price doesn’t carry a separate child rate, so for a young family the morning cruise is the more economical full day. Planning a proposal or anniversary? Pair it with our guide to the best cruise for a celebration.
The LUXE keeps the group to 14, so there’s always room and the crew has time for you.
4. Afternoon Cruise to Dia Island
At adult €125 / child €85 and 5 hours, the afternoon cruise is the same length and price as the morning one, just shifted later: you board at 15:30, sail to Dia for the swim stop and water activities, sit down to a nutritionist-designed Cretan dinner with local wine and Greek beer, and ride the sunset home. It’s the pick if you want your morning free for the city — the Knossos palace, the archaeological museum, breakfast in town — and still want a full cruise with golden light at the end.
The honest trade-off: afternoon wind on the north coast can put a little more movement in the sea than the glassy morning, and it’s dinner rather than the bigger midday spread. If calm water and maximum swim time top your list, the morning cruise wins; if a free morning ashore and a sunset finish matter more, this is your cruise.
All four cruises take families — the calm Dia Island water and shaded deck suit children of any age.
Which One Should You Book?
If you only remember one thing: every Heraklion cruise reaches the same beautiful Dia Island water, so match the format to your day, not the listing that shouts loudest.
