This crossing links busy, cosmopolitan Mykonos in the central Cyclades with volcanic Milos in the west. Mykonos and Milos are about 62 nautical miles apart, roughly 115 km, and the direct boat saves you a return to Piraeus or a string of changes. It suits travellers who want a few days of Mykonos followed by the slower pace of Milos, with its volcanic landscapes and the hilltop capital, Plaka.
Only one company regularly works this direction: Seajets, with high-speed catamarans. That keeps the timetable simple but also sets the price, which is high for a Cyclades hop. Fares on Ferryhopper started at €97.70 when we checked, and on the day we sampled, 12 August 2026, the single sailing cost €108.70. There are no car decks on these boats, so plan to rent a car on Milos.
Timing matters on this route. The service runs from March to November only, and even in season not every day has a sailing. On direct days the trip takes under 3 hours; on other days the boat follows a longer routing and the journey stretches past 5 hours, so check the duration shown for your exact sailing before you book.
You leave from the new port of Mykonos at Tourlos and arrive at Adamas, the harbour town of Milos on the island's north side. Both ends are easy to handle, and both islands have airports if you are flying in or out, which makes an open-jaw trip, landing on one and leaving from the other, a practical plan.
