A non student bus fare can cost about 30 euros but European and Greek students may receive a discounted price. Ferries can also range depending on the date booked and distance traveled but be prepared to spend about 40 euros per ferry ride (non-student).
How many days do you need for Greek island hopping?
It's possible to hop islands in Greece for a weekend or a whole lifetime. However, between a week and 14 days is usually enough to showcase the highlights of the region and get a taste for what it means to whiz over the Aegean Sea between sunbaked bays and ouzo-soaked marina towns.
Is it worth taking the ferry to Santorini?
The ferry from Athens to Santorini allows you to enjoy the beautiful Aegean Sea. The downside is depending on the time of year it may be difficult to get a boat from Athens to Santorini. In the off-season, there are only 2 boats a day making the trip. Another con is the time it takes to make the trip.
