Athens, Kalympaki marina

Kalympaki Marina sits in Elefsina on the Saronic Gulf, giving you a solid base for exploring both the Greek mainland coast and the islands to the south. It's a small operation with just 8 berths, so you get a quieter, more personal setup than the big commercial marinas closer to Athens. The industrial history of Elefsina — home to one of Greece's oldest ancient sanctuaries — gives the area a grittier, more authentic feel than the typical postcard sailing stop.
