I'd suggest taking the northern
route over (i.e. up the Evvia channel and through the Northern Sporades, crossing the N Aegean to the Dardanelles via Limnos and Gokceada or Bozcaada) then coming back at the end of your
cruise via the
Cyclades. Our favourite route is from Kusadasi via Ikaria (Evdhilos), Mykonos then either Syros/Kythnos/Poros/Aegina or Tinos/Kea/Sounion/Aegina. As long as you reach the Dardanelles before late June you should avoid the worst of the meltemi and the northern route has less
wind anyway. You can find details on all the
ports en route on the World Cruising Wiki (see link at top of page).
