Oceania Sirena: 8-Night Mediterranean

Lisbon cruise port is one of the most atmospheric arrivals in Europe. Ships sail up the Tagus River past the 25 de Abril Bridge (a near-twin of San Francisco's Golden Gate) and the Christ the King statue, with the city rising up on seven hills to the north.

Cadiz is the actual cruise port marketed as "Seville (Cadiz)" by cruise lines because Seville, Spain's fourth-largest city, is the primary day-trip draw from this port. Cadiz itself is one of Europe's oldest continuously inhabited cities, perched on a narrow peninsula jutting into the Atlantic on Spain's southwestern coast.

Malaga cruise port is the main gateway to Spain's Costa del Sol and Andalusia. The city sits on Spain's southern coast, about 130 kilometers west of Granada and 50 kilometers east of Marbella.

Barcelona cruise port is the busiest in the Mediterranean, handling millions of passengers a year across multiple terminals. The city behind it earns that traffic.

Cannes is a Mediterranean resort city of about 75,000 people on the French Riviera, known worldwide for its annual film festival but offering far more than red carpets and paparazzi. The city sits on the Golfe de la Napoule with the Esterel massif's red porphyry cliffs rising to the west and the rolling hills of Provence behind.

La Spezia is a working Italian naval and commercial city on the Ligurian coast, but cruise passengers know it primarily as the gateway to Cinque Terre, the five colorful fishing villages clinging to the cliffs along a rugged stretch of coastline just north of the city. The La Spezia cruise port sits at the edge of the city center, a short walk from the train station that connects directly to the Cinque Terre villages.
