A client wrote to me in March asking a question I get in some form almost every week. She had five nights, a party of eight, and a picture in her head: board in Mykonos, wake up under the caldera in Santorini. How much, and how long?
The honest answer took me three paragraphs and she booked ten days later, on a different itinerary than the one she had imagined. Not because I talked her out of Santorini, but because the distance between those two islands is the single most misunderstood number in Greek chartering, and once you understand it the week plans itself.
So here is the whole thing, with the real distances from our own sailing distance calculator, the documented depths and holding from the anchorage guides we publish, and the part almost nobody tells you: this route does not work the same way in both directions.
How far is Mykonos from Santorini by yacht?
There are three honest answers, and confusing them is where most of the bad advice starts.
- As the crow flies, about 60 nautical miles from Mykonos to the caldera at Oia, and about 67 to Vlychada on the south coast. The ferry companies publish 63 to 65 miles for their own track, which matches.
- As a yacht actually sails it, allowing for headlands, island channels and harbour approaches, our own sailing distance data puts the direct passage at 80 miles.
- Island hopping through Paros, Naxos and Ios, 97 miles.
The number that matters to you is the third one, and the reason is the whole point of this article. Nobody should sail this route in one go.
Sailed the way it is actually meant to be sailed, through Paros, Naxos and Ios, those 97 miles arrive in four short pieces instead of one long one:
- Mykonos to Paros, 30 nautical miles
- Paros to Naxos, 12 nautical miles
- Naxos to Ios, 30 nautical miles
- Ios to Santorini, 25 nautical miles
Seventeen extra miles over the direct passage buys you four islands, four anchorages and four evenings ashore. That is the whole argument of this article in one line.
How long does the direct passage actually take?
Between about five and twelve hours, depending entirely on what you are aboard. Those are planning figures, not brochure figures, and the difference matters.
The planning speeds we use are around ten knots for a motor yacht or power catamaran on passage, and six to seven knots for a sailing catamaran making reasonable progress. A captain never plans a passage at a yacht's top figure. P/CAT ELLY II documents a top speed of 20 knots and M/Y ONE documents 41, but nobody crosses this stretch of Aegean at 41 knots with guests aboard, breakfast on the table and a swell on the beam.
So the direct passage is about eight hours under power on a typical crewed catamaran, and closer to twelve under sail. A genuinely fast motor yacht changes that: M/Y STAR LINK documents a 24 knot cruise, which turns the same water into a morning rather than a day. On most of the fleet, though, you would leave Mykonos before breakfast and arrive at the caldera in the late afternoon, having seen nothing all day but water. Some people want exactly that. Most people, when they hear it out loud, do not.
Why is Santorini to Mykonos harder than Mykonos to Santorini?
Because the Meltemi blows from the north, and the two directions are not the same passage. This is the part that almost never appears in the guides, and it is the single most useful thing on this page.
The summer Meltemi is a northerly, strongest from the middle of July to the middle of August, typically Force 5 to 7 and gusting harder in open water. Every anchorage guide we publish carries the same standing advice: plan the southbound legs downwind, and take your overnights on lee and southern coasts.
Going south from Mykonos, that wind is behind you. The yacht settles, the motion goes long and easy, and the miles pass without anyone noticing them. Our own Ios island guide puts the last leg at 25 miles with the Meltemi astern.
Going north from Santorini in the same weather, you are pushing into it. The same 80 miles becomes a longer, wetter, slower day, and a sailing yacht will be tacking, which lengthens the distance again. It is entirely doable and crews do it all season. It is simply not the same holiday.
If your heart is set on one direction, make it Mykonos to Santorini. If your flights force the other way, tell me early, because in July and August that changes which yacht I would put you on.
What does the route look like broken into legs?
Four passages, none longer than three hours under power, with an island at the end of each. This is the shape of the week I book most often, and it reads like this.
Mykonos to Delos and Rhenia, then Paros
Delos sits twenty minutes from Mykonos and closes to visitors in the early afternoon, so the move is an early one. The Delos and Rhenia anchorage guide documents the site anchorage at 4 to 5 metres over sand and rock, holding only moderately good, with at least 35 metres of chain recommended, and visiting hours of roughly 08:00 to 15:00. South Bay on Rhenia next door gives excellent shelter from the Meltemi and is where you swim once the site is behind you.
Then 30 miles to Paros. In August, Naoussa harbour is competitive, so the move is to anchor outside in Plastira Bay and tender in. If the Meltemi is up, the east coast of the island around Piso Livadi and Drios gives shelter that Naoussa cannot.
Paros to Naxos, and the Despotiko detour
Twelve miles, the shortest leg of the week, which is why this is the day to spend somewhere rather than move. The Antiparos anchorage guide documents the Despotiko channel at 4 to 9 metres over sand with excellent holding, and calls it one of the most protected anchorages in the southern Cyclades in a northerly blow. It is a Cycladic ritual: anchor at the islet, swim, eat aboard.
On Naxos, Chora harbour carries 4 to 7 metres with the breakwater anchorage in the northeast corner giving Meltemi shelter, and Ormos Kalando on the southeast coast runs 3 to 6 metres over sand and is one of the best Meltemi lees on that side of the island. Anchor at Plaka for lunch. Visit the Chora by tender in the evening rather than lying off it.
Naxos to Ios
Thirty miles south, and the day the Cyclades stop being crowded. Ios is the classic overnight before Santorini for a reason: the port at Yialos has laid moorings in the east basin with excellent Meltemi shelter, and Manganari on the south coast runs 4 to 10 metres over sand with good holding and is well protected from the Meltemi, while being completely open to anything from the south.
If you have the appetite for a detour, Koufonisia and Amorgos sit east of this line and almost no Mykonos departure ever reaches them.
Ios to Santorini
Twenty five miles, two and a half to three hours under power, and the arrival that everyone came for. Approach the caldera from the south. The light in the late afternoon on that western wall is the reason people book this route in the first place.
Where do you actually stop between Mykonos and Santorini?
Six anchorages carry the week, and we publish documented depth and holding for most of them rather than adjectives. Depths and holding below come from published cruising sources, and your captain will confirm the anchor drop against current charts on the day.
- Rhenia, South Bay. Excellent shelter from the Meltemi, beside the archaeological site.
- Antiparos, Despotiko channel. Four to nine metres, sand, excellent holding, one of the most protected southern Cyclades anchorages in a northerly.
- Naxos, Ormos Kalando. Three to six metres, sand, one of the best Meltemi lees on the southeast coast.
- Ios, Manganari. Four to ten metres, sand, good holding, well protected from the Meltemi and wide open to the south.
- Folegandros, Vathi and Angali. Four to five metres, sand and weed, good holding, with strong gusts and swell when the Meltemi blows.
- Sikinos, Alopronia. Seven to ten metres, sand with some Posidonia, the island's only organised anchorage and open to the south.
Folegandros and Sikinos sit just west of Santorini and turn a four leg route into a five leg one. They are the two islands guests mention most often afterwards, which tells you something about what people actually remember from a week in the Cyclades.
Can you charter a yacht one way from Mykonos to Santorini?
You can, and I would usually advise against it, for a reason that has nothing to do with selling you a longer week. A yacht that finishes in Santorini has to get back to where it started, and somebody pays for that. It appears on your quotation as a delivery or repositioning fee, and on a one way Cycladic leg it is rarely small.
There is a second problem, which is that a one way charter compresses 80 miles into your only sea day. If the Meltemi is at full strength that morning, you have no flexibility. A week has slack in it. A transfer does not.
George Yachts is a weekly house. We do not run day charters, and the reason is exactly this: the value of a crewed yacht is in the days when nothing is scheduled. If what you genuinely need is to get from one island to another, the ferry is honest transport and I will tell you so. What we sell is the week around it. You can read where that thinking comes from on our Mykonos and Santorini comparison, which sets out why one of those islands is a base and the other is a stop.
How long is a boat ride from Mykonos to Santorini?
On a scheduled ferry, between about two and a half and three hours. That is the answer most people are looking for when they ask this question, and it is worth giving plainly before we go back to yachts.
Two operators run the route, Seajets and Golden Star Ferries, on high speed craft. Published crossing times cluster around two and a half to three hours, the longest scheduled service runs about three hours twenty, and foot passenger fares at the time of writing sit roughly between 79 and 97 euro. The ferry operators publish their own route distance as 63 to 65 nautical miles, which is why I gave you the crow flies figure above rather than a sailed one.
A yacht is slower than the fast ferry and always will be, because a fast ferry is a 35 knot machine with no interest in where you swim. If your only requirement is to be in Santorini this evening, take the ferry and I will help you no further. If you would like the four islands in between, read on.
Where does a yacht actually berth in Santorini?
Vlyhada Marina is the only properly protected port on the island, and in July and August it needs to be booked months ahead. That single fact reshapes more Santorini itineraries than any other.
The caldera itself is a flooded volcano, which means it is deep, steep sided and offers no real harbour. Yachts anchor below Oia for the sunset rather than below the Chora, where the caldera side is too steep for a comfortable swim. In a strong Meltemi the caldera can become uncomfortable, and the usual answer is to tuck into Oia's lee or move to a cove on the eastern side of the island overnight, then return for the sunset hours. Nea Kameni, the active volcanic islet, sits in the middle and most yachts anchor near it long enough for guests to tender across.
Full detail on the island, including where to disembark for flights home, is on our Santorini charter page.
What happens to this route when the Meltemi is at full strength?
The route bends east and south, and a good captain will have told you so before breakfast. The Meltemi does not usually cancel a Cycladic week. It reshapes it.
In practice that means taking the shelter the geography offers: the Kalando lee on Naxos rather than the west coast roadsteads, Manganari on the south of Ios rather than the exposed north, the Despotiko channel rather than an open Paros bay. Every one of those alternatives is documented in the anchorage guides linked above, which is why we publish them.
It also means accepting a layover day. A crew that keeps a documented all weather shelter in reserve and spends a day in it is doing the job properly. A crew that pushes on to keep an itinerary is not.
Which yachts in our fleet suit this route?
The ones that can make a 25 to 30 mile leg comfortably before lunch, which in practice means a power catamaran, a stabilised motor yacht or a larger sailing catamaran. Across the 65 yachts we represent, the shortlist for this corridor looks like this.
P/CAT ELLY II is the one I have been offering most for 2027, because she is a new hull entering her first season and her listing documents a top speed of 20 knots. On this route that is the difference between arriving at Ios for lunch and arriving for dinner. She runs 59,000 to 69,000 euro a week, with VAT at 6.5 per cent and APA at 25 per cent.
P/CAT ChristAl MiO at 34,000 to 48,000 euro is the value answer to the same question, a power catamaran her listing describes as catamaran stability with motor yacht speed. S/CAT Libra at 18,900 to 26,900 euro is the most accessible five cabin platform we have, and will sail this route happily in June or September when the wind is kinder. At the top, S/CAT Sol Madinina runs 65,000 to 85,000 euro with a crew of five.
One constraint decides the shortlist before any of this does. A commercially registered charter yacht carries a maximum of twelve guests however many berths she has, which on a route with four island stops is the difference between one yacht and two. If your party is thirteen or fourteen, read the twelve passenger rule before you fall in love with a boat.
One boat deserves a specific mention. S/CAT Madicon is listed for exactly this corner of the Aegean, her own description naming Folegandros, Sikinos, Ios and Anafi, and she is based at Santorini rather than Athens. If your flights land on Santorini rather than Mykonos, she is the obvious starting point. The whole fleet is on the charter yacht index.
What does a week on this route cost?
Between roughly 19,000 and 85,000 euro for the yacht itself, before the expenses that every crewed charter carries. The fleet starts lower than that, at 10,900 euro for S/CAT Alegria, but the Cyclades in summer reward a bigger platform.
On top of the base fee there are three things, and they are the three that surprise first time charterers.
- VAT. Greek charter VAT is not one flat number. It runs at 5.2, 6.5, 7.8 or 12 per cent depending on the yacht's certification and where she is registered, with 13 per cent as the statutory ceiling. Short charters and bareboat are taxed differently at 24 per cent. ELLY II, to use a real example, carries 6.5 per cent.
- APA, the advance provisioning allowance. Typically 20 to 40 per cent of the base fee depending on the yacht, paid up front and reconciled against real receipts at the end. ELLY II carries 25 per cent.
- Crew gratuity. The MYBA convention is 10 to 15 per cent, calculated on the base fee and never on the total. It is discretionary.
The full arithmetic, with worked examples, is in our cost breakdown, and the definitions are in the glossary under VAT, APA and gratuity.
When is the best time of year to sail Mykonos to Santorini?
June and September, and it is not close. The Meltemi is at its strongest from the middle of July to the middle of August, which is precisely when most people want to be here.
In September the water is warmer than June, the wind has eased, the restaurants become bookable again, and rates on the yacht side fall by 15 to 25 per cent from August. That combination is why September is the month I push hardest for this particular route, and why it is usually the first to go for the following year. There is more on the month by month picture in our seasonal guide and in the September piece.
For 2027, the Cycladic weeks that matter are already moving. Our own booking data showed a median lead time of 394 days on the 2027 requests we had taken by early August, with nothing under ten months. If you want the caldera in September 2027, the conversation is now rather than next spring. The 2027 hub has the availability picture.
When is this route wrong for you?
Four cases, and I would rather say them here than discover them with you on day three.
- You have children under about six. The Cyclades in July and August are the windiest charter ground in Greece, and 30 mile legs in a Meltemi are not a small child's holiday. The Ionian or the Saronic is the better answer, and I will say so.
- You want a beach club holiday. This is a moving week. If the plan is three days on the same sunbed, a villa is genuinely better value and I have told clients so.
- You are prone to seasickness and set on a sailing yacht in August. A stabilised motor yacht changes that experience completely. M/Y STAR LINK documents zero speed stabilisers, a 24 knot cruise and a 1.9 metre draft, and there is a whole stabilised shortlist if that is the deciding factor.
- You have only four nights. You can do it, but you will spend most of them under way. Four nights suits the Saronic. This route wants seven.
If any of those is you, the honest alternative is usually the quieter route west and south, which we wrote up in the Cyclades beyond Mykonos and Santorini.
What I would actually book
Seven nights, Mykonos to Santorini, southbound, in the second week of September. Delos early on day one and Rhenia to swim. Paros and the Despotiko channel. Naxos and the Kalando lee if the wind is up. Ios and a night at Manganari. Folegandros if the forecast allows, because it is the island people write to me about afterwards. Then the caldera, arriving from the south in the late afternoon, anchored below Oia, and the only evening of the week where nobody suggests doing anything at all.
That is 97 miles across seven days, which is fourteen miles a day, which is nothing. And it is the same 80 miles that frightened my client in March.
If you want that week, or you want me to tell you honestly that a different one suits you better, write to me. I read every brief myself. Start at the Cyclades cruising guide or simply send me your dates.
Sources and how these numbers were checked
Distances are from our own sailing distance data, compiled from the Greek Waters Pilot, captain observation and IYBA member network charter logs, and rounded to the nearest five miles. Anchorage depths, holding and shelter are from the island anchorage guides we publish, which draw on the Greek Waters Pilot, cruiserswiki and sailingissues, and which omit any figure a published source did not document rather than estimating it. Yacht speeds, rates, VAT and APA percentages are the documented figures from each yacht's own listing. Crew gratuity follows MYBA guidance. Where a figure was not documented, it is not in this article.
