Aegina Island is so close to Athens, that it makes a perfect day trip for a taste of Greek island life. It lies only a 40 minutes boat ride from Pireas, Athens' harbour suburb. Aegina is fairly large (87 sq km) so if you want to explore the whole island in a day, a scooter is necessary. Else it's the water, seafood, and easy life people come for. If Acropolis hasn't filled your desire for ruins, there are more ruins at Aegina town - Aegina was once a strong city state like Athens. If tours are more your thing, Aegina is also a part of the 3-islands-1-day cruise (Hydra, Poros, and Aegina), which is heavily advertised by the travel agents in Athens.
