There is no need to pay any fee to enter the island either by boat, ferry or plane .
What’s curious is that, upon leaving the island by boat from the main port of Santorini (Athinios), a small fee of 1.5 € must be paid. No need to worry about where to make payment of this fee, because at the same door to the boat or ferry, there is a person who is responsible to collect this small fee.
