If you are looking for a party, there is no way around the island of Ios. It is considered the true center of nightlife in the Cyclades and is therefore particularly popular with a young crowd. However, early risers who like to have the beach to themselves will probably also find their happiness here - because the party nights mean that it usually only gets a little livelier on the beaches in the afternoon. The monastery of Agia Ioannis and the regional vineyards are particularly worth a visit.
