Seabourn Ovation: 21-Night Mediterranean from Athens (Piraeus)

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.

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.

Valletta cruise port is one of the most visually dramatic arrivals on any Mediterranean itinerary. Ships sail into the Grand Harbour, a deep natural inlet flanked by honey-colored limestone walls that rise straight out of the water, with Valletta itself perched on the peninsula above.

Salerno is the eastern gateway to the Amalfi Coast, one of Italy's most celebrated stretches of coastline. Cruise ships dock at the Stazione Marittima in Salerno's port, a short walk from the city center and the starting point for trips along the legendary coastal road to Amalfi, Positano, and Ravello.

Rome's cruise port is in Civitavecchia, a working port town about 80 kilometers northwest of the city. That distance is the single most important thing to understand about this stop.

Florence (Livorno) cruise port is the main Tuscan stop on Mediterranean itineraries, but it's worth being clear about what you're actually docking at. The port is Livorno, a working industrial city on the Ligurian coast, about 85 kilometers west of Florence.

Monaco is a sovereign city-state on the French Riviera, just 2 square kilometers in size with about 39,000 residents, making it the second-smallest country in the world. Monte Carlo, its most famous district, is synonymous with wealth, casinos, and Formula 1 racing.

Marseille cruise port is France's busiest and one of the major stops on western Mediterranean itineraries. The city is France's second largest and its oldest, founded by Greek sailors over 2,600 years ago, and it has a rougher, more authentic edge than the polished Riviera towns further east.

Built on a narrow strip of land between the Mediterranean and the Etang de Thau lagoon, Sete is a working fishing port of about 45,000 people on the Languedoc coast. The city calls itself the Venice of Languedoc for its network of canals, though the comparison undersells what makes Sete different: this is a genuine fishing town where trawlers unload the catch at the port each morning and the restaurants cook what came in that day.
