A Greek islands cruise is one of the easiest ways to see the Aegean. You unpack once and wake up in a new port almost every day: whitewashed Mykonos, cliff-top Santorini, medieval Rhodes and ancient Crete.
This guide covers the best time to go, popular routes, what to do in each port and smart tips for first-time cruisers in Greece.
Key Takeaways
- The cruise season runs from about late April to October. May, June and September offer the best mix of weather and crowds.
- Most routes start in Athens (Piraeus) and stop at Mykonos, Santorini, Rhodes and Crete.
- Santorini is a tender port, so expect a boat ride and a cable car line to reach Fira.
- Small ships can visit quieter islands like Naxos, Paros and Hydra.
- Book shore trips early for Knossos, Ephesus and Olympia, or plan them yourself.
Best Time for a Greek Islands Cruise
The season runs from late April to October. July and August are the hottest and busiest months, with temperatures that can reach 100°F (38°C). The strong Meltemi wind also peaks in summer and can make some sea days rough.

Popular Greek Islands Cruise Itineraries
7-Night Classic Aegean
Athens (Piraeus), Mykonos, Santorini, Rhodes, Crete and often Kusadasi in Turkey for Ephesus. This is the most common Greek islands cruise route on large ships.
Eastern Mediterranean Combo
Many 7 to 12-night cruises start in Venice, Trieste, Rome or Istanbul. They add Greek ports like Corfu, Katakolon (for Olympia) and Santorini.
Small Ship and Yacht Cruises
Smaller ships visit quiet islands that big ships cannot reach, such as Hydra, Naxos, Paros, Milos and Patmos. These trips cost more but feel more personal.
Top Greek Cruise Ports and What to Do
Athens (Piraeus)
Take Metro Line 1 to Monastiraki or Thissio, about 30 minutes. From there, walk up to the Acropolis. Go early to beat the heat and the lines.
Santorini
Ships anchor in the caldera and passengers take a tender boat to the old port. Then ride the cable car up to Fira. On busy days, the whole trip can take over an hour, so get off early. Take a bus or taxi to Oia for the famous blue domes.
Mykonos
The new port is a short shuttle or 10 to 15-minute walk from town. Visit Little Venice, the windmills and the maze of white lanes. Some ships stay late so you can watch the sunset.
Rhodes
The medieval Old Town is a UNESCO site just steps from the dock. Walk the Street of the Knights and the city walls. Lindos, with its hilltop acropolis, is about 1 hour away.
Crete (Heraklion)
Visit the Palace of Knossos, about 20 minutes by taxi. It has little shade, so go first thing in the morning. The Heraklion Archaeological Museum is a great second stop.
Corfu
Corfu Old Town is a short walk or taxi ride from the port. It mixes Venetian forts, Italian-style streets and green hills.
Katakolon (Olympia)
Ancient Olympia, home of the first Olympic Games, is about 35 minutes away by bus or taxi.

Greek Islands Cruise Tips
- Book shore excursions early in peak months, or plan port days on your own to save money.
- Get off the ship first in Santorini to beat the tender and cable car lines.
- Wear comfortable shoes. Island streets are steep, uneven and often slippery marble.
- Pack sun protection, a hat and a refillable water bottle.
- Dress modestly for churches and monasteries, with shoulders and knees covered.
- Carry some euros in cash for small shops, buses and taxis.
- Expect port fees. Greece now charges cruise passengers a fee to visit Santorini and Mykonos, highest in peak months. It is usually added to your cruise fare.
Insider tip
Arrive in Athens a Day Early
Flights to Europe can be delayed. Fly into Athens at least one day before your Greek islands cruise. You lower your stress and get a free day to see the Acropolis and the Plaka district.
