Skiathos boasts some of the very best beaches in Greece and is said to be the most beautiful of all the islands. Full of Greek flavour, Skiathos moves at a gentle pace, from the tavernas and bars of its traditional villages to the coast's little beaches and crystal-clear water. A jewel in the blue Aegean Sea, this is one of Greece's most popular islands. The Greek island of Skiathos lies in the Aegean Sea and, although just 48 square miles, boasts over 60 beaches.
