Silver Ray: 9-Night Mediterranean from Venice

Trieste sits at the northeastern corner of Italy, pressed against the Slovenian border at the head of the Adriatic Sea. The city has about 200,000 residents and a distinctly Central European character that sets it apart from other Italian cruise ports.

Ravenna is a mid-sized city of about 160,000 people in Italy's Emilia-Romagna region, sitting on the Adriatic coast south of Venice. The city served as the capital of the Western Roman Empire, the Ostrogothic Kingdom, and the Byzantine Exarchate, leaving it with the finest collection of early Christian and Byzantine mosaics anywhere outside Istanbul.

Split cruise port is the main gateway to central Dalmatia and one of the most remarkable cities in Croatia. The city is built around and inside Diocletian's Palace, a 1,700-year-old Roman fortress that the emperor built as his retirement residence around 300 AD.

Dubrovnik cruise port is the southern gateway to Croatia's Adriatic coast and one of the most visually striking stops in the Mediterranean. Ships dock at Port Gruž, about 3 kilometers northwest of the Old Town, with the walled medieval city perched on a rocky peninsula jutting into the sea.

Katakolon is a small fishing village on the western coast of the Peloponnese, with a permanent population of only about 700 people. It exists on cruise maps for one reason: ancient Olympia, the birthplace of the Olympic Games, is 45 minutes inland.
