Only four of the islands that make up the group are permanently inhabited and these are Alonissos, Skopelos, Skiathos and Skyros. In terms of visitor numbers Skiathos is the most popular tourist island in the Sporades. With over sixty beaches to choose from, a number which have been awarded the Blue Flag award for safety and cleanliness, it is easy to find a secluded spot away from the crowds who usually head to Koukounaries Beach. Skopelos is the second largest of the islands and is mainly visited by holiday-makers from Skiathos who come for day-trips. It has very few beaches but its main attraction is the fact that there are many locations on the island that were used in the film ‘Mamma Mia’. Skyros is one of the least visited of the four islands due in part to its remote location and this has meant that the island has retained a great deal of its traditional character. Alonissos is a much quieter destination than Skiathos with only a few sandy beaches on offer, but has a lot in common with Skyros in that much of the original charm of this island is still prevalent.
