22-Night Transatlantic from Barbados

Barbados cruise port is in Bridgetown, the capital of the easternmost Caribbean island. Bridgetown Port (Deep Water Harbour) sits just outside the city's UNESCO-listed historic center, with modern terminal facilities including 21 duty-free shops, restaurants, car rental agencies, and a tourism office.

St. Lucia is one of the Caribbean's most topographically dramatic islands, defined by the twin volcanic peaks of the Pitons rising sharply from the southwestern coast. The Castries cruise port sits on the island's northwest side, with ships docking at either Pointe Seraphine (a duty-free shopping complex within walking distance of downtown Castries) or the La Place Carenage terminal on the opposite side of the harbor.

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.

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.

Cartagena is a historic port city of about 215,000 people on Spain's southeastern Mediterranean coast, in the Murcia region. Founded by the Carthaginians in 227 BC (as Carthago Nova), the city has been contested by Carthaginians, Romans, Moors, and Spanish kingdoms, and its layered history shows in the archaeological sites scattered through the compact center.

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.

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.
