Mykonos to Kos Ferry

The ferry from Mykonos to Kos is one of the Aegean's classic cross-archipelago hops, linking the Cyclades with the Dodecanese over roughly 99 nautical miles (about 184 km) of open water. Because the two island groups sit far apart, this is not a short shuttle: it is a genuine long-haul crossing served mainly through the summer season rather than year-round, and departures cluster in the peak months of August and September, typically two to four days a week.

Two operators cover the run. Blue Star Ferries uses conventional car ferries that carry vehicles, campervans and motorbikes as well as foot passengers, but their sailings usually thread through the eastern Aegean island chain, so total journey time can stretch to roughly ten to eleven hours. SeaJets runs faster high-speed vessels on the corridor, with the quickest connections completing the trip in around six and a half hours; several of their high-speed ferries also have vehicle garages, though space is limited and books up early.

What to expect on board

• Departure port: Mykonos New Port (Tourlos), north of the main town, not the old harbour.
• Arrival: Kos Town port, a short walk from the castle and old town.
• Intermediate calls: many sailings stop at islands such as Patmos, Leros and Kalymnos, and sometimes Ikaria or Samos, which is why crossing times vary so widely.
• Early starts: some departures leave Mykonos as early as the pre-dawn hours, so check your exact ticket time carefully.

Because frequency and vessel type shift week to week across the season, treat any single timetable as a snapshot and confirm the live schedule before booking. Fares generally start from around €67-75 for a standard economy passenger seat.
