Hydrofoil from Mykonos to Santorini

There are no hydrofoils operating on this route. Most of these ferries are highspeed catamarans but there is also at least one "regular" car ferry. Check schedules here: www.gtp.gr

The seas are generally calm in June but sometimes the wind is strong and the water is rough. There's no way to predict for sure what it will be like when you need it. The smaller the ferry the more chances for seasickness. Stick to the regular car ferry or the large highspeeds like the ChampionJet or Highspeed 7 and you'll be fine.

They are the main companies for the Cyclades. Usually it is better to book via the shipping company itself. You save time in communication in case something goes wrong e.g cancellation due to weather conditions or a possible strike.
