The crossing from Ios to Santorini is one of those short island hops that feels effortless — a quick stretch of Aegean sea between two of Greece’s most visited islands. Whether you’re moving on from Ios after a few days enjoying its famous beach scene, or fitting in a day trip before the sun goes down over Santorini’s caldera, this route keeps things simple.
Throughout the year there are 4 ferries per day on average. In summer (June–August), this increases to 6 per day, while winter sees around 2 per day.
