Oceania Allura: 24-Night Mediterranean from Lisbon

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.

Funchal is the capital of Madeira, a Portuguese island in the Atlantic Ocean about 600 miles southwest of Lisbon and 400 miles north of the Canary Islands. The island is volcanic, mountainous, and green, with a subtropical climate that keeps temperatures mild year-round.

Las Palmas de Gran Canaria is the largest city in the Canary Islands, a Spanish archipelago off the northwest coast of Africa. The city has about 380,000 residents and serves as a major embarkation port for Canary Islands cruises and a regular port of call on Atlantic, repositioning, and West Africa itineraries.

Santa Cruz de Tenerife is the capital of Tenerife, the largest of Spain's Canary Islands, located in the Atlantic Ocean about 300 km off the coast of Morocco. The cruise port sits in the heart of the city, directly adjacent to the commercial center and within walking distance of the main shopping street and waterfront.

Arrecife is the capital of Lanzarote, one of the Canary Islands in the eastern Atlantic Ocean about 125 km off the coast of West Africa. The island has about 155,000 residents and a landscape unlike anywhere else in Europe: volcanic craters, lava fields, black sand beaches, and an almost lunar terrain shaped by eruptions in the 1730s that buried a third of the island.

Tangier sits at the northwestern tip of Africa, where the Mediterranean meets the Atlantic and Morocco looks across the Strait of Gibraltar at Spain, just 14 km away. The city has about 1.

Cagliari is the capital of Sardinia, Italy's second-largest island, on the island's southern coast. The cruise port (Porto di Cagliari) sits directly at the edge of the old town, about a 10-minute walk from Piazza Matteotti and the base of the historic Castello district.

Naples cruise port is one of the most popular stops on Mediterranean itineraries, and it's easy to see why. The city sits on the Bay of Naples with Mount Vesuvius looming behind it, and it serves as the gateway to Pompeii, the Amalfi Coast, Capri, and Sorrento.

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.

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.

Palermo cruise port drops you into one of the most chaotic, layered, and rewarding cities in the Mediterranean. This is the capital of Sicily, sitting on the northwestern coast of the island along a gulf facing the Tyrrhenian Sea.

La Goulette is the cruise port serving Tunis, Tunisia's capital, located on the Mediterranean coast of North Africa about 12 kilometers northeast of the city center. The port sits at the entrance to the Lake of Tunis, a shallow lagoon separating La Goulette from downtown.

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.

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.

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.
