Aghios Kosmas Marina

37° 52.6′ N · 23° 43.6′ E

A large-yacht marina at Elliniko, south of Alimos, beside the old airport site now being rebuilt as the Hellinikon development.

Practical

VHF 9; mooring lines; minimum LOA 15 m, max about 80 m; fuel, water, power, parking (my-sea, updated September 2026). Not a small-boat stop. The Agios Kosmas reef off this coast (lit, west-cardinal buoy) lies just SE of the Alimos entrance — keep well off the shore.

Best for

Larger yachts wanting a berth near Glyfada
