Island hopping on Greek ferries
Ferries operate all year round in the Greek Islands, although the more remote might get only one ferry a week. The high season for frequent ferry sailings is June to September, with the tourist peak period in July and August so many Greek ferries set sail over a relatively short periods each year and lay idle for the rest.
Summer ferry schedules never used to be issued before May but ferry firms have already released their 2014 schedules. Each ferry company still publishes only its own schedule but there are now websites such at Greek Travel Pages where you can find comprehensive details of routes and Greek Island ferry connections. Most operators keep to the same ferry schedules year on year but it is not uncommon for companies to 'trade' routes, change boats, or alter schedules.
Low season ferry schedules used to be notoriously difficult to come by but ferry firms are now looking to increase tourism beyond the usual summer months. Greek Island hopping in the winter however usually means catching ferries on main island routes. Ferry firms must get licence to operate a main ferry route and that means providing a service all year round, even to the less popular islands. Bad weather will be a much bigger problem over winter and sailings will often be cancelled at short notice in bad weather.
