The Cyclades are the islands of the central Aegean, about 220 of them, named for the circle they form around Delos, the sacred island that the boats from Mykonos visit. Most are small, dry and windswept, with white villages and a port, yet no two feel alike, so the useful question is which two or three to choose and how the ferries link them. Five have their own pages on must30; this page sends you to the right one and adds five smaller islands worth a stop.
Santorini is for the caldera and the Bronze Age town of Akrotiri. Mykonos is for nightlife, sandy bays and the boat to Delos. Naxos, the largest, is for mountain villages, walks, long beaches and farm food. Milos is for its volcanic coast and boat trips. Paros is the easy all-rounder, with Antiparos a short crossing away.
The islands below suit other trips: Tinos for pilgrimage and marble villages, Syros for a real town with an opera house, Sifnos for cooking and walking, and Folegandros and Amorgos for cliff-top villages, a monastery on a rock face and quieter days.
Visit Panagia Evangelistria, then Pyrgos, the marble village
Tinos town and Pyrgos, Tinos
A full dayNo booking needed
Climb the avenue from the harbour to Greece's most venerated icon, then cross the island to a village of marble carvers.
What it is
Tinos is the island of Greece's most venerated icon. The Church of Panagia Evangelistria was built from 1823 to house an icon found that year after a nun's vision, and it crowns the avenue that climbs from the harbour. On 15 August, the feast of the Dormition, thousands of pilgrims arrive and some cover the way on their knees.
How to do it
Then cross the island to Pyrgos, the village of marble carvers, which KTEL buses from Tinos town reach a few times a day. Its Museum of Marble Crafts shows how Tinian craftsmen quarried and carved marble; it opens 10:00 to 18:00 until 15 October and to 17:00 in winter, closes on Tuesdays and costs €8. Ferries run daily from Piraeus and Rafina, and Mykonos is about 35 minutes away.
Good to know
No shorts or sleeveless tops inside.
Time needed
A full day
Best time
Any day except Tuesday, when the marble museum closes
Walk to Kastro and eat Sifnos cooking from its own clay pots
Sifnos (Kastro, Artemonas and Kamares)
A day: the walk in the morning, lunch afterNo booking needed
Walk about three hours across the island to earn a lunch of chickpeas baked overnight in a clay pot in a wood-fired oven.
What it is
Sifnos, birthplace of the chef Nikolaos Tselementes and many other cooks, cooks in clay. Its fifteen pottery workshops, in Kamares, Vathi and other villages, still make the lidded pot in which revithada, the Sunday chickpea dish, bakes overnight in a wood-fired oven, and the mastelo in which Easter lamb or goat cooks with red wine and dill; several sell from the workshop door.
How to do it
Earn lunch on foot: the island has 19 marked trails, and trail 1 runs 8.6 km, about three hours, from the hilltop archaeological site of Agios Andreas through Kastro, the island's capital until 1836, to Artemonas. Ferries from Piraeus land at Kamares in 2 to 3 hours by fast boat or 5 to 6 by conventional ferry, and boats continue to Milos.
Good to know
Look for revithada on Sunday menus. Spring and autumn are the walking seasons.
Walk neoclassical Ermoupoli and climb to medieval Ano Syros
Ermoupoli and Ano Syros, Syros
A dayNo booking needed
A neoclassical city founded by refugees in 1826, with an opera house modelled on La Scala, below a medieval hilltop quarter.
What it is
Syros is the Cycladic island built around a city. Ermoupoli was founded and named in 1826 by refugees from Chios, Psara, Kasos, Smyrna and elsewhere, grew rich on shipping and trade, and is still the regional capital; 2026 is its bicentenary.
How to do it
Start on Miaouli Square, under Ernst Ziller's town hall, then walk to the Apollon Theatre, opened in 1864 to designs by Pietro Sambo modelled on La Scala and other Italian opera houses. In the evening, take a bus or taxi up to Ano Syros, the medieval quarter topped by the Catholic cathedral of Agios Georgios, and walk down its stepped lanes. Ferries run daily from Piraeus, and Tinos is about 40 minutes away by fast boat.
Good to know
Theatre visits run 10:00 to 14:00, and 18:00 to 21:00 when there is no rehearsal or show; it closes from 2 to 30 November.
Time needed
A day
Best time
The theatre in the morning, Ano Syros in the evening
Walk Folegandros's cliff-top Chora and climb the path to Panagia
Chora, Folegandros
An eveningFree
A car-free village of small squares on the edge of a northern cliff, and a cobbled path up to a church on a rock.
What it is
Folegandros has no airport, and its Chora is the reason to take the boat. The village sits about 200 metres above the sea, 3.4 km up from the port of Karavostasis, and no vehicles are allowed in, so you move between its run of small squares on foot: Pounta, Ntounavides, Piazza. The Kastro, the medieval quarter, is the oldest part, and its houses, still lived in, form the edge of the northern cliff.
How to do it
From Pounta Square a cobbled path zigzags up in about 15 minutes to the church of Panagia, rebuilt between 1816 and 1821 on a rock that probably held an ancient temple; inscriptions and statue bases are set into its courtyard. In summer, fast boats reach Folegandros from Piraeus in about four hours; conventional ferries take around ten.
Climb the steps to the Hozoviotissa Monastery on its cliff
Hozoviotissa Monastery, below Chora, Amorgos
2 hours with the walk from ChoraFree
A white monastery built into a cliff some 300 metres above the sea, where the monks offer raki with honey and spices.
What it is
Hozoviotissa is the image of Amorgos: a white monastery about 40 metres long, built into a cliff on the south coast some 300 metres above the sea, with eight floors of cells, chapels and storerooms behind a facade that in places is barely five metres deep. Tradition says its icon arrived by sea at Agia Anna bay below, and Emperor Alexios I Komnenos endorsed the monastery in 1088.
How to do it
From Chora it is about 1.5 km on foot, half an hour, or a short drive followed by the steps. Blue Star sails all year from Piraeus to Katapola in about nine hours, and a small boat links Amorgos with Naxos daily.
Good to know
The monks ask men to wear long trousers and women long skirts, and offer visitors psimeni raki, the island's raki with honey and spices, and loukoumi. Entry is free.
Island-hop the Cyclades by ferry, with the wind in mind
Cyclades
A week or more for three or four islandsBook ahead
In the Cyclades the ferry is the road: a classic hop runs Paros, Naxos, then Ios or Santorini, timed around the summer wind.
What it is
Ferries are the road network of the islands. From Athens, Piraeus serves most of them, while Rafina is often the quicker start for Tinos and Mykonos. From Naxos the small Skopelitis sails daily all year to the Small Cyclades and Amorgos.
How to do it
A classic line runs Piraeus, Paros, Naxos, then Ios or Santorini. Conventional ships such as Blue Star's are slower but steadier; high-speed catamarans halve journey times, cost more and are the first to be cancelled when the meltemi, the dry north wind of July and August, reaches force 7 or 8.
Good to know
Plan one buffer day before your flight and be back in Athens the day before. Ferries leave on time, so reach the port early. For sailing, spring and autumn are calmer.
Time needed
A week or more for three or four islands
Best time
May, June or September, outside the strongest meltemi
Watch the caldera sunset from Imerovigli or the lighthouse
Santorini
1 hour, or 3 hours with the rim walkFree
Santorini's caldera sunset is the island's big moment; skip the crush in Oia and watch it from Imerovigli or the Akrotiri lighthouse.
What it is
Oia is where the famous sunset pictures come from, and it is packed well before dusk; cruise passengers add to the crush, which is why Greece now charges each one landing on Santorini €20 from June to September. You get the same light with fewer elbows elsewhere on the rim.
How to do it
Imerovigli is the highest village on the caldera cliffs, and a stepped path runs down to Skaros rock and the ruins of its fort. The lighthouse at Cape Akrotiri, still run by the Greek Navy, is the quiet option at the island's southwest tip. To end in Oia anyway, walk the caldera path from Fira in the afternoon; it takes under three hours.
Good to know
The caldera path has steep sections and unfenced edges. KTEL buses from Fira cost a few euros, cash only.
For a first trip, pair Santorini with Naxos or Paros: two or three days on the caldera, then an island with beaches and villages to explore at your own pace. For beaches, the west coast of Naxos is almost one long run of sand, Mykonos has its south-coast bays, and Milos has the strangest shoreline, though the wind decides which side you can swim on. Walkers do best on Naxos, Sifnos and Amorgos, which keep their networks of old stone paths. For food, Naxos grows much of what it eats and Sifnos built its name on cooking. Mykonos is the nightlife island. For quiet, choose an island without an airport, such as Folegandros, Sifnos or Amorgos.
How to combine them
The Greece page's island-hopping entry covers the boats and the wind; here is how the islands line up. Boats leave Athens from Piraeus, at the end of metro line 1, and from Rafina, east of the city and closer to the airport. Paros, Naxos and Santorini sit on one line from Piraeus that runs all year. Boats from Rafina call at Andros, Tinos and Mykonos, and Syros is a short hop from Tinos. Milos is on the western line, after Kythnos, Serifos and Sifnos, and in summer fast boats link Milos and Folegandros with Santorini, so you can go out one way and come back the other. Santorini and Mykonos have international flights, and Naxos, Paros, Milos and Syros have small airports, so you can arrive on one island and leave from another. Check timetables and crossing times on the operators' sites or with each island's port authority.
How many days
Give each island at least three nights. The island pages suggest three or four days for Santorini, three for Mykonos and four each for Naxos and Milos. A week covers two islands comfortably, ten days three, and two weeks lets you add a small one such as Folegandros, Sifnos or Amorgos. A crossing takes a morning or an afternoon once you count getting to the port and waiting, and in must30's view one more night on an island is worth more than one more island. Put Delos and any boat trip early in each stay, so a windy day does not cost you them.
When to go
The season runs roughly from Orthodox Easter to the end of October. May, June, September and early October are the comfortable months, quieter than high summer and good for walking. July and August are the busiest and bring the meltemi, the north wind that can stop small boats and make north-facing beaches unswimmable, so keep a plan for the south coast. From late October, services shrink: many hotels, tavernas and boat trips close, fast boats sail far less often, island buses switch to thin winter timetables and state sites change to winter hours on 1 November. Delos closes from December to March, and the Apollon Theatre on Syros shuts for maintenance in November. Conventional ferries keep serving the main islands all winter.
Questions travellers ask
Which Cyclades island is best for a first visit?
Santorini is the one most first-timers want, for the caldera, but two or three days there are enough. Pair it with Naxos or Paros, which are on the same ferry line, for beaches and villages. For a quieter first trip, Sifnos and Milos sit next to each other on the western line.
How many Cyclades islands can I see in a week?
Two, comfortably. Each crossing takes a morning or an afternoon, and wind can cancel boats, so three islands in a week leaves little time on each. Pick islands on the same line, such as Paros and Naxos, Tinos and Mykonos, or Sifnos and Milos.
Which Cyclades islands have an airport?
Santorini and Mykonos have international flights as well as flights from Athens. Naxos, Paros, Milos and Syros have small airports with domestic flights. Tinos, Sifnos, Folegandros and Amorgos have none, so you arrive by boat.
Are the Cyclades worth visiting in October?
Early October, yes: it is still within the season, and state archaeological sites keep summer hours until 31 October. Late in the month, services shrink fast: Mykonos buses switched to their winter timetable on 19 October 2026, Naxos buses thinned sharply, and many businesses on Santorini close towards the end of the month.
Do I need to book Cyclades ferries in advance?
On summer weekends and Greek holidays some fast boats sell out, so buy those tickets ahead. You can buy them on the operators' own sites or from travel agencies in the island ports, which the municipalities list on their tourism sites.
