Ionian Pelagos (www.ionionpelagos.com) runs two or three times daily in high season between Piso Aetos and Sami (Kefallonia), and once or twice from Piso Aetos to Astakos (on the mainland).
Between July and mid-September, the Meganisi II ferry runs twice daily between Frikes and Nydri on Lefkada.
West Ferry (www.westferry.gr) has in the past connected Frikes with Fiskardo (Kefallonia) and Vasiliki (Lefkada); that service has not run in recent years, but it’s worth checking the website to see whether it has resumed.
