From Athens Airport (Eleftherios Venizelos) take the X96 bus or Metro to Pireaus port. Head to E8 gate where the boats leave to Aegina Island.
From the port of Aegina turn right and follow the beach road that leads to the south part of the island passing the beaches of Marathonas and Aeginitissa. After 9km you will reach the beautiful fish village of Perdika. After the sign of ¨Welcome to Perdika¨on the crossroad to Sfentouri you turn right for 500m and when you reach the school entrance you turn right again.
Taxi cost around 14€ to Perdika Mare from Aegina Port, you may find also the bus timetable here.
Perdika is built around the small port. The beach, on the left side of the village, can be rocky, but the water is so clean that you can see the bottom of the sea.
You can chill out under the shadow of the trees and later visit the traditional restaurants and taverns of the area which are ready to serve you fresh fish enjoying the sunset.
