Hi Shirley,
Skopelos is a wonderful island and is very laid back. In fact it is VERY Greek! The islanders were offered an airport but refused it as they didn't want to become like Skiathos!
To get to Skopelos you have to fly to Skiathos and then get the ferry or flying dolphin to skopelos. There are 2 ports on skopelos, Skopelos town which both the ferry and flying dolphin stop at, and Loutraki where the flying dolphin also stops at. Loutraki is at the north of the island. Skopelos is a very quiet island and Skopelos town (also known as hora ) is the busiest place on the island.....although don't take this literally! There is one disco (very low key!) a jazz club on the harbour front which is excellent even though i am not a jazz fan!, a piano bar which is excellent and numerous restaurants which are superb. Finikas and Alexanders are among my favourites although there are many more.
Skopelos is a very mountanous island but is very easy to explore both on foot and by car. You do not need a jeep to access the island although to see the best of the island i suggest you hire a car for at least three days. The bus service which runs from Skopelos town to Glosssa and Loutraki in the north is very good but stops running at about 6pm. Taxis are a rare sight affter midnight unless you pre book!
For accommodation, Skopelos town offers the biggest choice. There is a lot of accomodation on the road between Skopelos town and Stafylos where you will also find a good range of accomodation. Panoramos also has a decent range of accomodation.
There are a few websites offering accommodation on Skopelos and the following may interest you. I have found these very usefull.
