Much of the Greek charter fleet is based in the area mostly at Alimos marina (Kalamaki)
Flights to and from Athens are numerous and good value. Getting to the departure marina is easy and quick.
Enormous selection of charter yachts
Two attractive itineraries for a one week cruise
You must cross shipping channel at start and finish (tiresome)
Crowded with other charterers less competent than you!
They are 6 night/7 day itineraries that with thought can be combined into 14 day cruises. If you have that long, consider the Southern Itinerary and continue south down the quieter East Coast of the Peloponnese.
There are facilities but few mooring spots. The harbour is noisy and protection from the Meltemi only moderate. If there is space in the marina, it is a better choice. Access to the town is excellent. Our photo.
