The most cosmopolitan island of the Sporades is Skiathos island, where you will find many bars, clubs, and cafes to enjoy your summer nights and evenings. Most of them are found along with the port of Skiathos Town and in the paved streets of the old town. There are also many beach bars around Skiathos that stay open till late at night and organize dance parties on the beach.
Nightlife on the other Greek islands of Sporades is not that intense. Skopelos island, Alonissos island and Skyros island do not have all-night clubs but nice lounge bars playing soft music. These bars usually stay open until 2 or 3 o'clock in the morning and offer a relaxing atmosphere. Alternatively, you can spend your night with a long dinner in the many seaside taverns of the islands.
