Can I bring my children on the ferry for free?
Yes, children aged 0-11 travel for free on the ferries. They have to be accompanied by an adult with a valid Eurail Greek Islands Pass at all times.
Children under 4 don't need a pass when they're not occupying a bed, berth or air seat. Children aged 4-11 need a Child pass - you can get 2 free Child passes with every Adult Pass. On the Eurail Greek Islands Pass page, check out prices under the tab that says 'Family'.
Children aged 12 and up on the first day of travel can get the Greek Islands Youth Pass.
