The Greek Islands: Athens and the Cyclades, done at the right pace
The Cyclades are the postcard Greece — whitewashed villages, blue domes, and a different island a short ferry away. The temptation is to chase five of them in ten days; resist it. Each ferry eats half a day, and the joy of the islands is the slow afternoon, not the harbour queue. Pair Athens with two, at most three, islands — ideally a mix of one show-stopper and one quieter, beachy one — and the trip finds its rhythm.
When to go
Late May to June and September are the sweet spots — warm sea, long evenings, and the islands busy but breathable. September is arguably the best of all: the sea is at its warmest, the crowds thin after the August peak, and the ferries run calm. July and August bring peak heat, peak prices and the meltemi — a strong summer wind that can whip up the Aegean and occasionally cancel the smaller ferries. Many tavernas and hotels close from November to April, so spring and early autumn are the season.
How long, and which islands
Give it nine to twelve nights: a couple in Athens to start, then three to four on each of two islands. A few combinations that work:
- Athens (2 nights) — the Acropolis early, Plaka's lanes, the Acropolis Museum, and maybe a day out to Cape Sounion's temple at sunset.
- Santorini (2–3 nights) — the icon: the caldera, Oia's sunset, cliff-edge wineries. Beautiful and busy; two or three nights is plenty.
- Naxos or Milos (3–4 nights) — the antidote. Naxos for mountain villages, long beaches and the best food; Milos for volcanic coves, a boat day and the lunar shore at Sarakiniko.
- Paros makes a relaxed hub if you'd rather one base with easy day-hops.
What's genuinely worth your time
- A boat day — around Milos's hidden coves or out from Naxos; seeing the islands from the water is the trip's best hour.
- Santorini's caldera — a wine tasting on the cliff and the sunset from a quieter spot than the Oia crush.
- Naxos's interior — drive up to Halki and Apiranthos, marble villages most day-trippers never reach.
- Long, slow taverna lunches by the water — grilled fish, tomatoes, a carafe of local white.
- The Acropolis at opening time in Athens, before the heat and the queues.
Good to know
- Book ferries ahead in summer, and know your boats — fast catamarans are quicker but pricier and more weather-sensitive than the big slow ferries.
- The meltemi wind can cancel sailings in July–August; leave a buffer day before any flight home.
- Fly into Athens and you can often fly home from Santorini or Mykonos, saving a backtrack.
- The islands are step-heavy and sun-exposed; bring proper shoes, and carry some cash for small tavernas and boat trips.
Common questions
When is the best time to visit the Greek Islands?
Late May to June and September are the sweet spots — warm sea, long evenings and the islands busy but breathable. September is arguably best of all: the sea is at its warmest and the crowds thin after August. July and August bring peak heat, peak prices and the meltemi wind, and many tavernas and hotels close from November to April.
How many days do you need for the Greek Islands?
Give it nine to twelve nights: a couple in Athens to start, then three or four nights on each of two islands. Each ferry eats roughly half a day, so two islands at a relaxed pace beat five in a rush. Add a buffer day before any flight home in case summer winds delay a sailing.
Which Greek islands should you choose?
Pair one show-stopper with one quieter, beachy island. Santorini for the caldera and sunsets (two or three nights is plenty), then Naxos for mountain villages, long beaches and great food, or Milos for volcanic coves and a boat day. Paros makes a relaxed single base if you'd rather day-hop from one island.
How do you get between the Greek islands?
By ferry from Athens' port of Piraeus and between the islands. Fast catamarans are quicker but pricier and more weather-sensitive than the big slow ferries. Book ahead in summer, and remember the meltemi wind can cancel sailings in July and August. Flying into Athens and home from Santorini or Mykonos often saves a backtrack.
