When to go to Greek Isles cruise

Mykonos, Ephesus, Rhodes, Santorini and Crete from Athens.

A week from Piraeus around the Aegean: whitewashed Mykonos, the Roman city of Ephesus in Türkiye, the medieval walls of Rhodes, Santorini's caldera and Minoan Crete. Late spring and early autumn are warm without the August crush.

How long to stay

8–11 days is the sweet spot.

Flight time

About 10h from the US East Coast, 2.5h from Europe, 7h from South Asia.

Good to know

  • Santorini anchors offshore and uses tenders; take an early one, the cable car queue back can take an hour.
  • Ephesus is hot and shadeless; go first thing and bring water.
  • Check whether your passport needs anything extra for the Türkiye call.
