The port of Piraeus acts as the marine gateway to Athens, and is served by many ferries. Cruise ships also regularly visit, especially during warm months. Generally, pedestrian ferry users will be closer than cruise passengers to the Metro station providing access to Athens; walking distances can vary considerably.
