What makes the Cyclades a special destination?
The Cyclades combine Santorini and Mykonos, two of Greece's best-known islands, with the almost uninhabited, sacred island of Delos and quieter destinations such as Naxos and Paros. The name of the group describes its shape: the islands form a circle around Delos, which Greek mythology holds to be the birthplace of Apollo and Artemis.
Unlike Crete or the Dodecanese, the Cyclades have always been part of the Greek heartland and were never split off under foreign administration; their distinct character instead comes from Cycladic architecture, with its white, cube-shaped houses, and from the islands' particular geology, above all the volcanic caldera of Santorini. This page covers Santorini, Mykonos and Delos in detail, along with the island group's own ferry connections.
The same rules apply to entry requirements and the time zone as for the whole of Greece; details are on the Greece page.

What kind of destination are the Cyclades?
The Cyclades consist of around 30 islands of very different character: volcanic Santorini, night-owl Mykonos, fertile Naxos as the largest island, and the marble island of Paros. What they share is the characteristic white-and-blue architecture and mostly barren, windswept terrain.
The name Cyclades («those lying in a circle») goes back to the central position of the sacred island of Delos, which was already regarded as the religious centre of the Aegean in antiquity. The island group covers around 2,570 km² and, at 1,004 m on Mount Zas on Naxos, is markedly lower than Crete or the Dodecanese.
Santorini is a geological special case: the island is the rim of a collapsed volcanic crater, whose last major eruption around 1600 BC buried the Minoan settlement of Akrotiri under ash. Mykonos, by contrast, is flat and windy, known both for beach clubs and nightlife and for its traditional Chora, built with narrow lanes as a defence against pirates.

Which places are worth visiting in the Cyclades?
Santorini with Oia and Fira on the crater rim, plus the Akrotiri excavation site, and Mykonos with its Chora and the windmills of Kato Mili are the heavyweights for visitors. Delos as an uninhabited World Heritage site, Naxos with the ancient marble gate Portara, and Paros with quieter beaches round out the picture.
Santorini: Oia, Fira and Akrotiri
Oia and Fira sit around 300 m above the sea on the rim of the caldera formed by the eruption around 1600 BC; Oia is famous above all for its sunset, which is why crowds gather along the crater rim in the early evening. In the south of the island lies Akrotiri, a Bronze Age settlement preserved by volcanic ash and now viewable under a protective roof; frescoes, multi-storey houses and a drainage system testify to a highly developed town.
Mykonos: Chora and Kato Mili
The Chora of Mykonos is a maze of narrow, white lanes, originally laid out to make it harder for pirates to find their bearings. At the southern edge of town stands the windmill row of Kato Mili, built in the 16th century by Venetian rulers to grind grain; of the roughly 28 mills the island once had, 16 survive, 7 of which form the well-known skyline above the Chora.
Delos
The uninhabited island of Delos, a UNESCO World Heritage site since 1990, was the religious and commercial centre of the Aegean from the 10th century BC onward and is held in mythology to be the birthplace of Apollo and Artemis. The extensive excavation site includes the Sanctuary of Apollo, the Terrace of the Lions and an ancient theatre; the island can only be reached by boat from Mykonos during the day, and overnight stays are not permitted.
Naxos and Paros
Naxos, the largest and most fertile of the Cyclades, greets arrivals with the Portara, a freestanding marble gate from an unfinished 6th-century-BC temple of Apollo at the harbour entrance. Paros adds a quieter side of the Cyclades with the old town of Parikia and the fishing village of Naoussa, and is also known for its historically prized white marble.

When is the best time to visit the Cyclades?
May/June and September/October offer warm beach weather without the biggest crowds and with more reliable ferry service than in winter. From June to September the inter-island ferry network is at its densest, but Santorini and Mykonos are also busiest then, and the Meltemi wind blows strongly.

Niederschlag: NASA POWER, Monatsmittel 2001–2020.
Station data show dry, warm summers and mild but windy winters on both islands; the Meltemi, a strong north wind, blows especially in July and August and can noticeably disrupt ferries on Mykonos. Outside the season, from November to March, many hotels, restaurants and ferry connections on both islands close.
Anyone wanting to avoid the crowds is better off planning the Oia sunset outside high season, or seeking out Imerovigli as a less crowded viewpoint on the same caldera. Delos can only be reached by boat in calm seas; crossings are cancelled on days with strong wind.
According to the Federal Foreign Office and BMEIA, wildfire risk exists across large parts of Greece from spring to autumn, including the Cyclades in dry summers (as of September 2026).

What applies to entry into the Cyclades?
The Cyclades are part of Greece, and the same rules apply as for the rest of the country: Swiss, German and Austrian nationals enter with a passport or national ID card, without a visa and without a fixed limit on length of stay thanks to Schengen or the EU freedom of movement, respectively. Details and the rules for other nationalities are on the Greece page.
There is no separate border control for the Cyclades; travellers arriving by air or ferry from another Schengen state often pass no additional passport check. What applies at the time of travel is set by the FDFA, the Federal Foreign Office and BMEIA, explained in full on the Greece page.
For details on visas, length of stay and special rules, see griechenland.json — this page covers only points specific to the Cyclades, such as ferries and airports.

What health precautions do you need for the Cyclades?
The same recommendations apply to the Cyclades as to all of Greece: no vaccination is mandatory, but healthytravel.ch and the CDC recommend hepatitis A and up-to-date routine vaccinations for most travellers. Medical care is available on Santorini and Mykonos through small clinics, while more serious cases are often flown to Athens.
Healthytravel.ch generally recommends for Greece the routine vaccinations under the Swiss vaccination schedule as well as hepatitis A for travel to rural areas; the site states that malaria risk exists only in rare, sporadic individual cases. Mosquito protection against West Nile virus makes sense from May to October, though the Cyclades are less often affected than the mainland because of their limited freshwater areas.
Sun protection is especially important on Santorini and the other islands, as the wind often masks the heat, making sunburn set in unnoticed more quickly. In more serious medical emergencies, patients from the smaller islands are usually transferred to Athens.

How safe are the Cyclades for travellers?
Like the whole of Greece, the Cyclades are considered a fundamentally safe destination with no elevated crime rate. The practical risks are mainly strong wind affecting ferry service, unsecured crater edges on Santorini, and, in crowded tourist spots, pickpocketing.
The Federal Foreign Office and BMEIA note pickpocketing in crowds as a general risk across Greece; on Santorini and Mykonos this mainly affects busy lanes and viewpoints such as Oia in the evening. In high summer the Meltemi wind can grow strong enough that ferries between the islands are cancelled at short notice.
On Santorini, the paths along the crater rim in Oia and Fira are partly unsecured and can be slippery when wet; particular care is warranted at dusk, when crowds gather for the sunset. Delos has no emergency infrastructure, and visitors depend on the boat crew and the water they bring with them.

How do you get to the Cyclades and between the islands?
Santorini (JTR) and Mykonos (JMK) each have their own international airports with seasonal flights across Europe and connections to Dubai; by sea, overnight ferries run from Piraeus, along with fast ferries and catamarans between the Cycladic islands themselves. Delos can only be reached by day boat from Mykonos.
| Route | Mode | Duration |
|---|---|---|
| Piraeus – Santorini | Ferry | around 5 to 8 h, fast ferry from around 5 h |
| Piraeus – Mykonos | Ferry | around 2 h 30 min to 5 h |
| Athens – Santorini | Domestic flight | around 50 min |
| Athens – Mykonos | Domestic flight | around 45 min |
| Mykonos – Santorini | Fast ferry | around 2 to 3.5 h |
| Mykonos – Delos | Excursion boat | around 30 min, daytime only |
| Mykonos airport – Chora | Taxi, bus | around 15 min |
According to current flight data, Santorini (JTR) serves around 55 to 56 nonstop destinations in 22 to 23 countries, mostly seasonal flights within Europe plus a nonstop route to Dubai; more than three-quarters of all departures go to Athens. Mykonos (JMK) reaches around 48 to 49 nonstop destinations in 19 to 22 countries, with a focus on Athens and London and likewise a nonstop route to Dubai.
By sea, Blue Star Ferries, Seajets and other operators run several times daily between Piraeus and the two main islands; fast ferries reach Mykonos in around 2.5 hours, and Santorini in 5 to 8 hours depending on the vessel. Between Mykonos and Santorini, up to 8 fast ferries run daily in high season, with the fastest catamarans taking around 2 hours 10 minutes.
Delos can only be visited with organised excursion boats from Mykonos; the crossing takes around 30 minutes. Overnight stays on the uninhabited island are not permitted, so a visit must always be planned as a day trip.

What money do you need in the Cyclades?
The national currency is the euro, as in all of Greece. Card payment is widespread on Santorini and Mykonos, but is considered relatively expensive: both islands rank among Greece's costliest destinations, especially for accommodation with a caldera view.
In Fira, Oia and the Chora of Mykonos, practically all restaurants and hotels accept cards, and ATMs are also widespread. On smaller Cyclades such as Naxos or Paros, card acceptance is somewhat lower, especially in small tavernas inland.
As in the rest of Greece, tipping is not obligatory: 5 to 10 percent in restaurants is customary, while leaving small change is enough in bars and cafés. Anyone visiting Santorini or Mykonos should budget for markedly higher prices than on the Greek mainland, given the high demand in high season.

Where is best to stay in the Cyclades?
On Santorini, the most sought-after and expensive rooms are those with a caldera view in Oia and Fira; cheaper options lie away from the crater rim, for instance in Kamari or Perissa on the east coast. Mykonos is centred on the Chora and the beaches in the south of the island.
Cave hotels, carved into the caldera's rock, are the typical form of accommodation on Santorini and are booked out months in advance in high season. Travellers looking for cheaper stays move to the island's east coast, but lose the direct crater view.
In the Chora, Mykonos offers historic Cycladic houses, while the south beaches feature large beach-club resorts at a correspondingly higher price level. Naxos and Paros are overall cheaper and less crowded, with a mix of simple guesthouses and family-run hotels.
What do you eat in the Cyclades?
Cycladic cuisine thrives on fish, capers and local cheese: Santorini is known for its small, sweet cherry tomatoes and the Assyrtiko white wine grown in volcanic soil, Mykonos for «Kopanisti», a spicy, creamy cheese.
Santorini's volcanic soil is barely suited to large-scale farming, but it produces especially aromatic cherry tomatoes and capers, used in many local dishes such as tomato-keftedes fritters. The island's Assyrtiko wine is regarded as one of Greece's best-known white wines and is grown on traditional basket-shaped vines trained close to the ground, which withstand the Meltemi wind.
Mykonos is known for Kopanisti, a spicy, fermented cheese served on bread or as a dip. Naxos, thanks to more fertile soil, is considered the culinarily more varied island, with its own potato farming and Graviera cheese; Paros adds fresh fish from the fishing village of Naoussa.
What culture shapes the Cyclades?
Cycladic culture reaches back to the early Bronze Age, with the simple, abstract Cycladic idols carved from marble as its best-known legacy. The white-and-blue architecture of the islands is a later tradition, in part only unified through regulation in the 20th century.
The Cycladic culture of the early Bronze Age, around 3200 to 2000 BC, left behind slender, geometrically reduced marble idols that later influenced artists such as Pablo Picasso and Constantin Brâncuși; many originals are on display at the Museum of Cycladic Art in Athens. From the 10th century BC, Delos was the religious centre of the whole Aegean and remained so into Roman times.
The white houses with blue shutters that define today's image of the Cyclades go back to local building traditions of lime-washing against heat and vermin; under the military dictatorship of 1967 to 1974, white lime-washing was even mandated for a time, to unify the look for the rising tide of tourism.
What experiences are worthwhile in the Cyclades?
Highlights include the sunset over the caldera in Oia, the Akrotiri excavation, a day trip to Delos and the windmills of Mykonos. Active travellers find hiking trails in the highlands of Naxos and, on all the islands, good conditions for sailing and windsurfing thanks to the steady Meltemi.
History and archaeology
- Akrotiri, Santorini: a Bronze Age town preserved under volcanic ash, often called the «Aegean Pompeii».
- Delos: UNESCO World Heritage site, ancient Sanctuary of Apollo, reachable only by day boat from Mykonos.
- Portara, Naxos: freestanding marble gate of an unfinished temple of Apollo at the harbour.
Active and outdoors
With Mount Zas at 1,004 m, Naxos has the highest highlands in the Cyclades and is more popular with hikers than the flatter Santorini or Mykonos. Thanks to the reliable Meltemi wind, the Cyclades, especially Paros and Naxos, are considered one of the best windsurfing and kitesurfing areas in Greece.
Experiencing the islands
Anyone wanting to combine Santorini and Mykonos with quieter destinations takes the fast ferry to Naxos or Paros, where prices are lower and beaches less crowded. A boat trip from Santorini to the offshore volcanic islets of Nea Kameni and Palea Kameni combines a walk on the crater with a swim in warm sulphur springs.

How do you travel responsibly in the Cyclades?
Avoiding Santorini and Mykonos in high season and choosing the off-season or quieter islands such as Naxos and Paros instead eases pressure on infrastructure and water supply, which are often scarce on the volcanic, dry Cyclades. On Delos, strict consideration for the archaeological fabric applies.
- Use water consciously, since Santorini and Mykonos must desalinate or import most of their drinking water.
- On Delos, stay strictly on the marked paths and do not take any finds or stones.
- Avoid cruise-ship days in Fira and Oia where possible, since visitor numbers at the caldera are highest on those days.

What can the Cyclades be combined with?
The Cyclades combine well by fast ferry with Crete to the south or the Dodecanese islands to the north, with seasonal routes running for example from Santorini to Heraklion or from Naxos towards Kos. Via Athens, a combination with the Greek mainland is also an obvious option.
Seasonal ferry and flight connections run from Santorini onward to Crete, with the ferry crossing taking several hours depending on the vessel. Anyone wanting to link several Cyclades plans a route via Mykonos, Naxos and Paros using the dense summer fast-ferry connections; outside the season, transfers between smaller islands are less frequent and waiting times are possible.

Who are the Cyclades suited to, and who less so?
The Cyclades suit travellers who want to combine Cycladic architecture, volcanic geology and Greek island flair with upscale comfort. Santorini and Mykonos suit less well anyone looking for a cheap or quiet destination; Naxos or Paros are the better fit for that.
Santorini works well for couples and photographers who want to experience the sunset over the caldera, Mykonos for anyone seeking nightlife and beach clubs. Travellers looking for calm, lower prices or hikes in the highlands find what they are after more on Naxos or Paros than on the group's two best-known islands.
