Hi, is there an opportunity to arrive in dubrovnik from any place in greece by bus or ferry?? (not airplane).  Please not going in Bari or other city in Italy (it's expansive the trip greece italy dubrovnik). Thank you very much for the answer. 

no one knows it?? i don t believe!!!

As far as I know there are no ferries from Greece to Croatia. We have many tourists who wish to travel from Dubrovnik to Greece as well, currently the only option is via Bari in Italy.

We are preparing a travel section dedicated to this question, I will post a link here as soon as it is ready.
