The harbor of Aegina, being close to Athens, is always crowded - especially at weekends. Yachts moor stern / bow-to using their anchors either on the North quay, where there are depths of 2.0 – 2.5 meters, or on the South quay, where there are depths at the West end of 5.0 – 6.0 meters but little more than a meter at the East end near the slipway.
A yacht should keep well off the quay in either spot, since the ferries cause quite a wash on entry. Outside the harbor is a small marina, Aegina Marina, protected by a long detached breakwater, where yachts berth on long pontoons. However, this is usually filled with local yachts on permanent moorings and there is little space for visitors.
