The distance from Mykonos to the island of Ios is 63 miles (102 km). The most convenient way to get to Ios is by taking a high-speed ferry. For a more leisurely trip, slow ferry options are available as well.
If you're interested in island-hopping en route to Ios, you could take an "indirect" ferry, which makes stops at other Cycladic Islands nearby.
Ferry schedules can become much more limited in the low season (mid-September through mid-June), so be sure to check that the ferry is running if you want to travel from Mykonos to Ios at that time.
By Fast Ferry
Duration: 2 hours
The fastest and most convenient way to get from Mykonos to Ios is to take a high-speed ferry. These hydrofoil ships skim the waves to get you to Ios in no time, but seasick-prone travelers should note that these ferries can be quite bumpy in windy conditions.
Economy and business class tickets are available. You can bring a car or motorcycle / vespa on board, but this will increase your ticket price depending on the size of your vehicle.
These ferries can be popular in the high summer season, so be sure to book your ticket in advance if traveling at that time.
By Slow Ferry
Duration: 4 hours 45 minutes
If you're looking to take in the sights and sounds of the Aegean in a more leisurely way, consider taking a slow ferry from Mykonos to Ios. These larger ships offer more open air space than the fast ferries, which can be easier on travelers who get seasick.
It's recommended that you book a numbered seat rather than a cheaper general ticket, which does not guarantee you a seat. That way, you can sit back and relax with a Nescafe Frappe or tyropita (Greek cheese pie) as you make your way to Ios.
By Indirect Ferry
Duration: 5 hours 30 minutes or longer depending on the route
If you want to explore other islands en route to Ios, you can take an "indirect ferry" from Mykonos. These ferries stop at other Cycladic islands, such as Santorini or Naxos, before continuing on to Ios.
The length of these journeys varies depending on how long the connection time is on the other island but if you have time and want to tell your friends that you just "popped over" to Santorini for lunch, this could be a good option for you.
Economy and business class tickets are available on these ferries and note that an indirect trip may include a mix of fast and slow ferries. It's possible to bring a vehicle on board regardless, but keep in mind that will increase the price of your ticket.
