Agios Kosmas Marina is a big and modern marina based very close to Athens, Greece. Built to host the Olympic Games 2004 sailing events, it is just 15km away from the centre of Athens next to the Glyfada suburb. Since then it has offered good shelter for a variety of private and charter yachts and offers daily, monthly and annual berthing all year round.
The stunning islands of the Saronic Gulf are a quick sail from here and popular destinations, with sound infrastructure and ideal sailing conditions. With almost 100 islands and rocky outlets in the area, it makes for an amazing sailing trip on a yacht charter. The area abounds with attractive towns, Byzantine castles, little fishing ports, ancient sites and ideal anchorages.
Approach to the marina is straightforward and docking assistance and guidance is available through VHF as well as tender pilot mooring assistance. The port entrance channel faces north with an opening of 40 meters and depths vary from 4.5 to about 6.7 meters. The port is protected by a breakwater that stretches for about 1000 meters to the southwest. The outer perimeter is protected by natural boulders. From the North it is protected by a triangular-shaped breakwater extending to the south.
Facilities
Agios Kosmas Marina can accommodate 337 boats in total, on both permanent and floating pontoons for yachts up to 90m, all supplied with power and water. The marina has a generator in case of a power failure. There is also a dry dock for winter berthing; however there is no repair yard.
The marina has excellent 24-hour security with CCTV and security personnel. Firefighting and emergency systems are located at each pier. Sanitary facilities are also on site and it is possible to organize re-fueling with a day’s notice.
Other facilities include a touchdown and lift-off area (TLOF) for helicopters, four main car park areas, a vacuum sewage system, a laundry service and a slipway for trailers.
All the amenities of the chic and busy Glyfada suburb are close by.
Getting there and away
The marina is only 25 km away from the Athens International Airport and 12 km away from the commercial port of Piraeus.
We’ve guided many guests who base their week on Agios Kosmas Marina, and we can say with confidence it’s a practical starting point if you want easy access to Athens and the Saronic Gulf coastline. Agios Kosmas Marina is located in Elliniko, on the Athens coast, in central Greece, right by the Argosaronic Gulf. From here, you’re close to the city’s services, and you don’t waste your first day in long road transfers.
Actually, the biggest advantage we’ve noticed is logistics. Most travelers arrive via Athens International Airport, which is the main gateway for the region. From the airport to Elliniko you can reach the marina by road, and the route is straightforward for a day charter or a full-week plan. Our guests who have trusted us typically appreciate that they can pick up the boat without turning the holiday into a marathon.
For sightseeing on land, Athens is obviously the headline. You can combine a morning in the city with an afternoon afloat. If you prefer a coastal rhythm, the Saronic Gulf offers classic options for short hops and longer sailing days. Based on our experience, popular destinations in this wider area include the islands of Aegina and Poros, and also the more relaxed approach toward the coastlines facing the gulf. In good conditions, a one-week itinerary often feels flexible: you can mix island stops with calmer stretches of shoreline.
We also advise planning around local conditions and daylight. The gulf has plenty of sheltered passages near the main islands, but wind and sea state can change quickly. We have seen that guests enjoy building a route around whichever harbor feels best that day!
One more practical note: Elliniko is near major road connections serving the Athens area, so provisioning and last-minute supplies are usually manageable. And if you want to extend the trip, ferries from the Athens region commonly connect to Saronic islands, which can help if you’re coordinating crew changes or returning on a different schedule.
We state with certainty: Agios Kosmas Marina is a strong base for a coastal week around the Saronic Gulf, with Athens and its airport access making the whole plan simpler—especially for first-time sailors.
