Kalamaki or Alimos Marina is one of the largest marinas in Greece and is considered the ideal base for sea-loving voyagers eager to explore the Greek islands, many of which are within leisurely sailing distance (i.e. Saronic Islands). It is located south west of Athens, 15 Km from the city center, 8 Km south of Piraeus port and 30 km from El. Venizelos International Airport (IATA: ATH).

It is served by a dense transportation network of trams, buses and taxis, with stations being just outside the Marina. The bus line (Χ96) stopping just outside Alimos Marina provides a direct connection to the Athens International Airport. The tram stops at 'Pikrodafni' and 'Marina Alimou' and connects to the metro, which also provides a stop at the airport.
