A first week in the Cyclades: choose two islands and stop there

What to take away

• Three nights on Santorini is plenty. Most people book five and spend two of them queueing.
• Do the Fira to Oia caldera walk early, from Fira, downhill-ish, before 09:00.
• Book ferries before hotels. The schedule decides which pairings are even possible.
• Never take the last ferry connection before a flight. Wind cancels boats, not planes.
• One rental car day on Naxos is worth more than three organised excursions.

The four-island week is a trap

Everyone starts with four islands. Santorini, Mykonos, Paros, Naxos. It looks like value: more places for the same flight. Then you count the mornings. Each island change is a checkout, a taxi to a port, a ferry that boards 45 minutes early, a taxi at the other end and a check-in. That is roughly half a day, four times, out of seven.

The other cost is subtler. You never learn an island. You never find the bakery you go back to, or the beach that is empty at 18:00 because everyone else has left. You get the first-day version of four places, which is the version already in every video you have seen.

Two islands, one crossing. Santorini for the thing Santorini is actually good at, and Naxos because it has space, food and a town you can walk around at night without a plan.

• Each island change costs about half a day.
• Santorini is a three-night island, not a five-night one.
• Naxos absorbs four nights easily and gets better on day three.

Ferries first, hotels second

This is the one piece of sequencing that matters. Ferry routes in the Cyclades change with the season, and a connection that runs twice daily in August might run three times a week in May. If you book the hotels first and then discover the boat, you end up either paying for a fast catamaran at twice the price or losing a day.

Santorini to Naxos is roughly two hours on a fast ferry, closer to three on a conventional one. Both operate in season. The fast ones are more expensive and more likely to be cancelled when it is windy, because they are the ones that cannot handle the swell. That is a real trade-off, not a footnote.

Book the ferry with the names as they appear on passports, arrive at the port 45 minutes before departure, and expect the boarding process to look like chaos. It is chaos, but it is functional chaos, and the crew will get your suitcase to the right island.

Santorini in three nights, done properly

The caldera walk from Fira to Oia is about ten kilometres along the rim and is the single best thing on the island. It takes three to four hours, it is exposed the whole way, and after 10:00 in summer it is genuinely unpleasant. We started at 07:15 from Fira and finished in Oia at 11:00 with time for a long breakfast before the crowds arrived from the other direction.

Stay in Imerovigli rather than Oia or Fira if the view matters. It sits on the highest part of the rim, it is on the walking route, and it costs meaningfully less than Oia for the same caldera. Fira is the practical base if you would rather have buses, shops and cheaper food.

The sunset is fine. It is a good sunset. It is also two thousand people standing on the same castle ruin in Oia, and if you have walked past it that morning you already have the better photograph. We watched ours from a terrace in Imerovigli with a bottle of wine, and the view is the same view.

Naxos is the reason the week works

Naxos is bigger, greener and considerably less expensive than Santorini. The Chora has a Venetian castle quarter you can get lost in for an hour, a long waterfront, and a Portara, the marble doorframe of an unfinished temple standing alone on a headland, which is free and best half an hour before sunset.

The beaches run down the west coast in a line: Agios Prokopios, Agia Anna, Plaka, Mikri Vigla, Kastraki. They get emptier and windier the further south you go. There is a bus, but a rental car for one or two days makes the whole island available, including the mountain villages.

Take a car up to Halki and Apiranthos. Halki has the old distillery and a cluster of cafes under plane trees. Apiranthos is built entirely from marble and is about forty minutes of switchbacks inland. Have lunch up there and come down for a swim. That was the best day of the week and it cost the price of a rental car and some petrol.

The wind, and why the plan needs slack

The meltemi wind blows through the Cyclades mostly in July and August, and it cancels ferries. Not often, but often enough that building a plan with no margin is a bad bet. A cancelled ferry the day before your flight is the one genuinely trip-ruining event in these islands.

So the rule is simple: never travel to the airport island on the day you fly. We flew out of Santorini, which meant returning from Naxos the day before and sleeping near the airport. It felt like a wasted evening when we planned it. It was insurance, and the ferry that day was 90 minutes late.

The same wind is why we moved a beach day. Wednesday was forecast at force six on the west coast, so the plan swapped it for the inland village drive and moved the beach to Thursday. That took one tap and nobody had to redraw a week in a group chat.

What we would change

We booked one sunset dinner in Oia and it was the least good meal of the trip for the most money. The restaurants on the rim are selling a view, and they know it. Eat inland in Pyrgos or Emporio, where the same island cooks for people who live there.

We also skipped the volcano and hot springs boat trip, and I am still not sure that was right. Everyone who has done it says the hot springs are lukewarm and brown. Everyone who has done it also mentions it unprompted, which suggests it stuck.

And we should have given Naxos five nights instead of four. The last full day was the first day nobody wanted to do anything, which is usually the sign that a place has finally stopped being a destination and started being somewhere you are staying.
