The lovely island of Skopelos
"Dolphin spotting galore"
Visited Skopelos as a present to myself after graduation. My greek friend often holidays there and recommended it.
The island was beautiful, had some lovely beaches but was quite quiet (that was a good thing for me!)
Lots of couples, not so many kids. Lovely harbour area with many restaurants.
The ferry goes to lots of different islands but the nearest is Skiathos, and when you arrive you fly in via here and then get the boat over.
Typical greek village feel to it with white houses and hills.
