To Lesvos is best to get by plane. Lesvos is served throughout the year from European destinations by Aegeon Air, member of Star Alliance .
Direct Chartert Flights from Europe during summer season approx .: April / May to October with Air Berlin, Transavia.
My tip: Have a look at the Aegeon Airlines website at: .aegeanair.com/special-offers/low-fare-calendar/ and search for cheap flight days.
Ship and ferry routes throughout the year from Piraeus, Thessaloniki, Kavala and Aivalik (Turkey)
