The chart

Where the boats actually sail

Nearly every trip we list from Heraklion crosses seven nautical miles to Dia Island and anchors in one of the sheltered coves on its south side. In the east, the one Agios Nikolaos trip on our list is a semi-private catamaran that sails Mirabello Bay towards Spinalonga. In the far west, we list one shared catamaran: the Balos and Gramvousa day from Kissamos. Tap a route for the trips that sail it.

How sailing in Crete actually works

Most of what we list sails to Dia Island, the bare little island a short way off Heraklion, because that is where the calm water, the swim stops and the easy logistics are. The real choice is how you go. A semi-private trip puts you on a shared boat — up to 10 guests on a sailing yacht, 22 to 25 on a catamaran — for 70 to 145 euros a head, which is the best value for couples and solo travellers. A private charter is the whole boat to yourselves, from 390 euros for a 4.5-hour sail to Dia on an Elan 37 that takes up to eight; for four people that is about the price of four 98-euro seats, so it pays off for a group rather than for a couple.

The thing a booking page does not spell out is the wind. From June to September the Meltemi blows from the north to north-west, and on a strong day the far-western run to Balos and Gramvousa, the most exposed trip we list, is the first to be cancelled or rerouted. Dia’s south-side coves and the water around Spinalonga and Kolokitha are more sheltered, which is one reason most of the trips we list are Dia trips. The Meltemi is most persistent in July and August; May, June, September and October are usually calmer, and October is about a third less crowded than August.

Sailing in Crete: frequently asked questions

How much does a sailing trip or catamaran cruise in Crete cost?

2026 prices on the trips we list: a semi-private day cruise costs 70 to 145 euros per person (Dia from Heraklion, Spinalonga from Agios Nikolaos), with a meal, drinks and snorkel gear in the fare; a hotel transfer, where one is offered, is usually extra. A five-hour coastal sail from Heraklion is the cheapest seat we list at 65 euros, with water but no meal. The shared Balos and Gramvousa catamaran is 220 euros per person. A private whole-boat charter to Dia runs from 390 euros for a 4.5-hour sail on an Elan 37 that takes eight to 990 euros for a Dufour 520 that takes sixteen, which only works out once your group is big enough to share the cost. The per-person price is almost always all-in on board, so there are few surprises on the day.

What is the difference between a private and a semi-private cruise?

On a semi-private cruise you share the boat with other guests — up to 10 on the sailing yachts we list, 22 to 25 on the catamarans — pay per person (70 to 145 euros) and follow a fixed route and departure time. It is the social option and the best value for couples and solo travellers. A private charter is the whole boat to yourselves. Every private on our list is a sailing yacht to Dia, from 390 euros for an Elan 37 that takes eight to 990 euros for a Dufour 520 that takes sixteen, and the listings also differ in hours and in what is included. You pick the departure and set the pace with no strangers aboard. For four people the 390-euro boat costs about what four 98-euro seats do, and full it works out at about 49 euros a head, so it pays off for a group rather than a couple. It is also calmer for kids, non-swimmers and anyone wary of crowds.

Which port do the cruises leave from, and is hotel transfer included?

Most of the trips we list leave from Heraklion port and sail to Dia Island, about 7 nautical miles offshore. The one Spinalonga and Kolokitha catamaran we list sails Mirabello Bay in the east from Agios Nikolaos marina, and the one Balos and Gramvousa cruise leaves Kissamos port in the far northwest, which is a long transfer if you are based around Heraklion. No trip we list includes a hotel transfer as standard. Several offer one, usually at extra cost: the Balos boat offers a private return transfer from your hotel, and the 70-euro semi-private lists hotel pickup as a booking option. On every trip we list you can request a transfer when you book, but its price and availability are confirmed only afterwards. Check the transfer terms on each booking page, which also shows the meeting point on a map.

When is the best time of year to sail in Crete, and what if it is windy?

June and September suit most people: the sea is 22 to 25°C and the Meltemi is off its July and August peak. May and October are about a third less crowded than August, with the sea at 19 to 20°C in May and 22 to 23°C in October. The Meltemi, a north to north-west wind, blows from roughly June to September and builds from late morning, so a morning departure is usually the calmer one; a strong spell can blow day and night for several days and cancel trips. The run to Balos and Gramvousa is the most exposed trip we list and the first to be cancelled or rerouted, while Dia’s south-side coves and the water around Spinalonga are more sheltered. No trip on our list promises a reschedule or a refund for weather, so read the cancellation terms before you book.

Will I get seasick, and are the trips ok for kids and non-swimmers?

A catamaran sits flat and does not heel like a sailing monohull, so the motion is much gentler, and the anchorages at Dia and around Spinalonga are sheltered from the summer wind. Face forward, get fresh air and bring tablets just in case. Most trips we list suit families: sheltered anchorages you can swim straight off, snorkel gear and SUP boards, and on the catamarans swim vests, inflatables or water toys. The exception is the 65-euro coastal sail, which takes guests aged 6 to 17 only with a legal guardian and no one under six. Non-swimmers can stay aboard comfortably, and a morning departure is usually the smoother one for sensitive stomachs.

Is lunch, drinks and snorkel gear included, and can we swim during the cruise?

Yes, there are dedicated swim and snorkel stops at anchor, often 1.5 to 3 hours in clear water at Dia, Kolokitha or Balos, with snorkel gear and SUP boards on every trip we list except the 65-euro coastal sail. Inclusions vary by trip: the per-seat Dia boats and the catamarans include a meal and drinks, and on the 145-euro catamaran the meal is a chef-cooked seafood menu with an open bar. Some private yachts serve fruit salad and drinks, with a full menu as an optional add-on on request, and the coastal sail includes water only. Bring your own towel, as every trip on our list asks. Check each booking page for exactly what is included.

Do I need a separate ticket for Spinalonga, and how long do the trips last?

Not for the trip we list. The one Spinalonga boat on our list, the 140-euro semi-private catamaran from Agios Nikolaos, stops for swims around Spinalonga and in Kolokitha Bay and shows you the fortress from the water; its listing states no landing. The fortress island, the former leper colony, has its own entrance ticket if you visit it another way. On length, the Spinalonga cruise runs 5 hours, the Dia trips 4.5 to 6.5 hours and the Balos and Gramvousa day 7 hours, swim stops included. Afternoon departures run about as long as the morning ones; in the main season most leave between 15:00 and 16:30 and are back around 21:00, so we list no shorter sunset option.

Is a boat trip in Crete worth it?

For most visitors, yes — it is the one day that shows you the island from the water rather than from a car. On our list, 70 to 145 euros per person buys four and a half to six hours out on a semi-private boat: a skippered trip to Dia or around Spinalonga, two to three hours anchored in a clear cove for swimming and snorkelling, and a meal with drinks on deck. If you are picking a single splurge day on Crete, a sailing trip plus a good taverna dinner is hard to beat.

Should I book ahead, and can I cancel or get a refund?

Book early for July and August, especially for an afternoon departure or the Balos and Gramvousa day; shoulder-season midweek dates are much easier. Most trips we list need 24 to 48 hours’ notice. Every trip on our list offers free cancellation up to 24 hours before the trip, though booking fees are non-refundable, and none promises a reschedule or a refund if the weather cancels a sailing, so read the terms before you pay. Booking online holds your place without relying on a phone call or email on a busy summer day.
