The regular passanger and ferry lines are in traffic between Italian (Venetia, Trieste, Ancona, Pescara and Bari) and Croatian harbours. The daily ferry line connects Rijeka and Split throughout the entire year. The line continues to Dubrovnik three times a week. The ferries that go from Rijeka to the southern part of coast are a good solution for the drivers who can avoid a hard drive down the coast in that way. 

Jadrolinija runs nearly all ferries in Croatia, helped by a few local ferry companies. Local Jadrolinija ferries connect all islands to the mainland and there is a coastal ferry from Rijeka to Dubrovnik. Ferry services from one island to another are much spottier. Don't assume that there "must be" a ferry from one island to another. Service is year-round on most routes although a few are summer only. Ferries are generally much more frequent in the summer.

All harbours, including the ones on the islands, are reachable by regular ferry lines. During the summer season the frequency of rides increases on all lines.
