Saronikos has Aigina that it was Greece’s first capital, so the first Greek museum was duilt there. In Salamina you can find Euripides’ cave, and a visit in Hydra and Spetes will show you why the Greek War of Independence was succesful: because of the sea capital that was offered by the rich shipowners of these two islands. So you can access these museums only by boat! But as a part of a daily or more excursion, Saronikos offers really unique options. After you reach the island, you can get to the place just by..asking a local!
