Transport between them can be patchy, but a new service linking Zakynthos with Corfu which started this year now brings all the islands (bar Kythira) together. Zakynthos is otherwise linked to Kefallonia with an old-style open deck ‘slipper’ ferry; Kefallonia includes Ithaki on its local small ferry route to Nydri on Lefkada. There is no link (except for the new service) from Lefkada to Paxi/Corfu. Corfu has links to Paxi and its little know satellite islands just to the north. Kythira has an airport with flights to Athens and ferries to Crete (Kissamos) and the Peloponnese (Gythio, Kalamata, and Neapoli).
My fiancee and I are heading to Greece in July. We’ve been to Naxos, Paros, Mykonos, and Santorini. This time we plan on being there July 1 to 23. We’re definitely including Milos, and one of Paros or Naxos. Any recommendations for other islands? Any particular ferry routes we should consider? Some “less touristy” islands are a must (for at least one island). We can be lively or very chilled. Thanks and best wishes!
