It is not straight forward to get to Skyros; the island has a domestic airport with 40 min flights from Athens only 3-4 times per week with Olympic airways, and 50 min flights from Thessaloniki with Sky Express twice a week. Ferries from Kymi, a port in Euboea, 3 hours north of Athens sail daily to Skyros, a 90-minute journey. That’s it. No connections to other local ports or airports, except an occasional charter flight from Europe in the summer.
I met up in Athens with my two grown daughters, following a pledge we have made years back; to visit a new Greek island every summer- there are so many on our list- Greece has over 200 inhabited islands- we will never run out of destinations. This summer we chose Skyros.
