Piraeus to Santorini ferry: Athens to the Cyclades

The Piraeus to Santorini ferry is the classic gateway from Athens to the Cyclades, with fast catamarans and comfortable conventional ships crossing the Aegean to the islands' most famous caldera.

How long is the crossing?

High-speed ferries reach Santorini in around five hours; larger conventional ships take longer but cost less and ride the Aegean more steadily.

Blue Star Ferries is the mainstay conventional operator; high-speed catamarans run alongside it, especially in summer.

Fast ferry or conventional?

Fast catamarans save time but cost more and can be cancelled in strong summer winds (the meltemi). Conventional ships are slower but more comfortable in a blow and carry vehicles more readily.

If your plans are tight, a conventional ship is the more reliable choice on a windy day.

Island-hopping from Piraeus

Piraeus is Athens' great port and the hub of Cycladic ferry travel; many Santorini sailings call at Paros, Naxos or Ios en route, making island-hopping easy.

Santorini's port is Athinios, below the caldera cliffs; buses, transfers and pre-booked hotels' pickups meet the ferries for the climb up to Fira and Oia.

Prices and tips

Fares depend on ferry type, season and whether you take a vehicle. Summer is busy and popular sailings sell out, so book ahead — especially the fast ferries.

Most visitors travel as foot passengers and use local transport on the island, where roads are narrow and parking is tight.
