Does anyone have info on taking a ferry from Italy (Rome) to Greece (Athens or Syros)? I cannot make heads or tails of the sites I have found online! Thanks!

There are various ferries from the east coast of Italy to Greece - from Venezia, Ancona, Bari or Brindisi to Igoumenitsa or Patra. From Roma, the nearest is Ancona, a 3 or 4-hour journey by train.
The best ferry companies are:
www.superfast.com
www.minoan.gr
www.anek.gr
From Igoumenitsa, you can get a bus to Athens, but it's better to go to Patra, which has both trains and buses to Athens.

I have taken the Superfast from Bari to Patra, Greece. I highly recommend it--I had a first-class outside cabin. There is a restaurant, cafeteria, disco, and swimming pool on board.

I've done the Italy to Greece ferry 5 time. I'm wondering if you've had more luck figuring things out and am wondering what it is exactly that you need to know.

Of course, as geoffhamer has pointed out, there are not ferries to Athens from Rome. There are ferries from Italy's west coast to Greece's east coast.

They run, of course, from Italy's east coast to Greece's west coast.

Oops!

Thanks for the info! I will do a little more research on the site mentioned.
