Getting to Kythnos from Santorini

Kythnos island in Greece

If you're planning to do a little island hopping from Santorini on the way back to Athens, Kythnos is certainly a place you can consider.

It's a very different island to Santorini, known for it's great hiking, landscapes, and nature.

Whilst I personally would prefer to add another island stop between Santorini and Kythnos, it is possible to sail directly there a few times a week.

During the summer, a ‘tourist' ferry operated by Seajets leaves Santorini heading for Kythnos once per week. There's also a more regular and slower ferry that travels the Santorini Kythnos route 2 or 3 times per week.

How to get from Santorini to Kythnos

Kythnos is closer to Athens than it is to Santorini, and so whatever method of travel you choose to get to Kythnos from Santorini it is going to involve a reasonable amount of travel time.

As there isn't an airport on the island of Kythnos, flying isn't really possible. That said, you could potentially fly from Santorini into Athens International Airport, and then take a ferry from Athens to Kythnos. I'm not sure how much time this would save you though.

The best way to travel from Santorini to Kythnos is to use a ferry.

During the the busiest months of summer, you may expect up to between 1 and 4 direct ferries per week from Santorini to Kythnos. These ferries to Kythnos from Santorini are operated by Zante Ferries and SeaJets.

You could also look at indirect routes, such as sailing from Santorini to Syros, and then taking a ferry from Syros to Kythnos.
