i didn't visit many islands when i went to greece, stuck to the mainland prety much, but i hope to next time...but vaggos is right the mainland does have beautiful beaches
but since the thread is about islands...
i passed through lefkada on the way to kerkira...so didn't have enough time to see it...but from what i did see...i didn't really like
kerkira was a beautiful island, but i liked the towns etc not so muh the beaches (not that i really got the chance to go swimming)
my favourite island which i visited was zakynthos, beautiful beaches and we were taken by a little boat to a small island called "marathonissi"...the bluest water i have ever swam in...also saw some "careta careta" lol but it is strictly for swimming only...only thing was the poms have taken over in zakynthos...we walked a tavern called "greek tavern" and i couldn't help but think....well where the hell are we? africa?
