Oceania Allura: 10-Night Mediterranean from Trieste

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.

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.

Kotor cruise port is one of the most visually spectacular arrivals in the Adriatic. Ships sail through a deep fjord-like bay (Boka Kotorska) surrounded by limestone mountains that rise steeply from the water, with the walled medieval town of Kotor tucked at the base.

Athens cruise port is in Piraeus, a busy port city about 10 kilometers southwest of central Athens. Piraeus is its own city, not just a terminal, and it handles cruise ships, island ferries, and commercial traffic all at once.

Kusadasi cruise port is Turkey's busiest and the primary gateway to Ephesus, one of the most significant ancient Greek and Roman cities in the world. The port sits on Turkey's central Aegean coast, about 95 kilometers south of Izmir, with ships docking at the Ege Ports cruise terminal right in the middle of town.

Istanbul cruise port is one of the most extraordinary arrivals in the world. Ships sail up the Bosphorus Strait between Europe and Asia, past Ottoman palaces and Byzantine ruins, and dock at Galataport, the underground cruise terminal in the Karaköy neighborhood right in the center of the city.
