6-Night Royal Caribbean Mediterranean Cruise

With 28 centuries of celebrated history, Rome holds the edge when it comes to unrivaled adventures. The city that sparked the world’s largest empire is very much alive today with a jumble of ancient ruins, world-renowned art and vivacious street culture. Here you can live la dolce vita, recalling the glory days of Ancient Rome and twirling forks full of pasta in a trattoria. Ride past centuries-old basilicas in a three-wheeled Ape Calessino, or stand in awe of paintings by Italian masters at Villa Borghese. Whether it’s Vatican City’s spiritual allure, Trastevere’s backstreet charms, or the Colosseum’s embattled legacy— The Eternal City endures with endless adventures.

Although originally called “Nakaia,” France’s Nice is as delightful as its name suggests to English speakers. Take a bus or taxi into Nice’s Old City to explore its history-spanning architecture and pristine French Riviera beaches with your Nice cruise. Or stick closer to Villefranche-sur-Mer, where your ship will dock, and take a day-trip to the mountaintop town of Eze. No matter how you spend your time in the de facto hub of France’s Cote d’Azur, you’ll enjoy the added benefit of being close to Italy, which means delectable pizza, fragrant espresso and the sounds of a second Romance language.

It’s easy to see why Barcelona is the most-visited city in Spain. As the capital of the country’s Catalonia region, this cityscape’s cultural mosaic pieces together a 2,000-year-old hodgepodge of sun-drenched beaches, cutting edge architecture, and a world-renowned dining and drinking scene. Catalan architect Antoni Gaudí left his modernist handprint all over the city, while medieval treasures linger in historic Gothic Quarter squares. Get lost in the whimsical gardens of Park Güell or savor a chef-led Catalan cooking class. Browse art collections dedicated to Picasso and Miro— or ride a cable car to the top of Montjuïc Hill, relishing citywide views along the way.

Spain’s third largest city, Valencia offers a little bit of everything, from historic sites and bustling city squares to placid beaches. Soak up the sun at Malvarrosa Beach along the urban seafront, or head to El Saler for a more remote beach experience surrounded by white-sand dunes and pine trees. Cruise to Valencia and get your culture fix at Gothic Valencia Cathedral, and see the 15th-century renaissance paintings housed in its interior. Head to Plaza de la Reina in the city’s old town and do some people-watching over a fresh glass of horchata, a classic Valencia beverage made from almond milk with cinnamon and spices, or take a picnic lunch of fresh pears and local cheese to the quiet Turia Gardens.

Cartagena greets you with its ancient Mediterranean port on Spain’s southeastern coast. Originally governed by the Carthaginians and subsequently by the Romans, Arabs and Castilians, this pedestrian-friendly city is a history buff’s dream port. Visit the 2,000-year-old Roman Theatre and the attached museum, where you’ll find an ancient altar to Jupiter and a statue of Apollo. Then, check out the late 19th-century modernist architecture of Cartagena’s historic center. Cruises to Cartagena, Spain allow you to stroll down blue-marble-tiled pedestrian-only Calle Mayor. Or take the 30-minute drive to the Batteria de Castillitos, a medieval-style fortress situated among the picturesque mountain landscape.
