It is very important to note that there are two types of ferries: regular and fast. There are daily regular ferries and high-speed boats that depart from the port of Piraeus in Athens to Santorini island. The frequency of itineraries depends on the season. During summertime, the itineraries are very frequent (more than one per day). The cost of the ferry tickets depends on the type of boat that you will select to travel with.
Santorini island has ferry connections with the following ports; Piraeus port (Athens), Ios, Naxos, Paros, Crete, Mykonos, Tinos, Syros Rhodes, Anafi, Chalki, Diafani, Folegrandos, Kos, Kasos, Kea, Kimolos, Koufonissi, Kythnos, Lavrio, Milos, Serifos, Sifnos, Sikinos, Thirassia.
The journey between the Athens (Piraeus) and Santorini (Thira) is between 5 and 8 hours, depending on the type of ferry you are taking.
If you plan to travel during July and August, it is best if you have booked several days or weeks earlier to avoid hitches. You should also know that round-trip/return ferry tickets come with a considerable discount. Ferry ticket prices are fixed and do not change with the seasons.
