Was in Skala last September and Lassi in 2001,Skala is the better resort for tavernas and the beach,down the steps and go right towards the headland but don't go any further unless you've got no shame that is!
As for northern...take an mp3 loaded up...enjoy the scenary...you must visit Myrtos bay,again go to the right of the bay for the best conditions.
Hope to go back this year,perhaps you can report back,have a great time,John Elias.
