Boats leave from Tourlos, Mykonos's New Port, 3km out of Chora, and dock at Piraeus, 10km from central Athens with a metro line connecting the two. Check in 45 minutes ahead for SeaJets or Golden Star Ferries catamarans; the slower Blue Star Ferries conventional boat takes cars, useful if you are dropping a hire vehicle before flying out. Piraeus has multiple terminals, so confirm the gate number in advance.

Mykonos to Piraeus keeps the same six-sailings-a-day, year-round schedule as the outbound leg, but the problem here is usually a flight out of Athens rather than an onward island hop. The fastest crossing is 2h45m; the conventional ferry takes 5h. Moderate wind risk means meltemi days in July and August can bump you onto a slower or earlier boat, so travellers with tight afternoon flights should build in a two-to-three-hour margin, not just for the airport transfer.
