Western Mediterranean 7 netter • Rome (Civitavecchia), Italy • Legend of the Seas

The Eternal City endures with endless adventures, so it’s definitely worth exploring before your cruise from Civitavecchia. Rome is just an hour from the port by train, so spending a few days here is easy and convenient. Start each morning with a frothy cappuccino and a warm, flaky cornetto in an al fresco café and watch the city wake. Then head to the Palazzo Massimo, home to one of the world's biggest collections of ancient art. Or visit the thermal Baths of Diocletian, where you can see two ancient, decorated tombs dating back to the early second century AD. And of course, no visit to Rome is complete without a trip to the famous Colosseum, which once hosted gladiator contests, battle reenactments and Roman dramas. If you’re a foodie, you’re in the right city. Roman cuisine is all about simple, fresh, unfussy flavors. Think thin and crispy pizza cooked in wood ovens, homemade pasta tossed in simple sauces, crispy fried vegetables and decadent breakfast pastries often stuffed with cream.

The third-largest Italian city and one of the oldest in Europe, Naples combines deep history and modern verve. Check out the extravagant Royal Palace of Naples, the former home of the royal family, with its beautiful tapestries and frescoes. People-watch from a streetside cafe in the Sanita district with a glass of wine and slice of classic margherita pizza.

Start your Marseille adventure at the port, where fishing boats and yachts bob close to one another and the fish market Quai des Belges still sells the day's catch. Then hop on the tourist train at Quai du Port for the steep climb to the neo-Byzantine Basilique Notre-Dame de la Garde. Check out MuCEM museum to trace the first footprints of Mediterranean history, then relax beside the crescent-shaped colonnade and fountain at Palais Longchamp.

Palma de Mallorca is the perfect place to immerse yourself in history and beauty. Go back in time to the 14th century at Bellver Castle, with its mix of Arab arches and Roman-inspired fortification. Catch a wave on the golden sands of El Arenal beach. Then, tuck into cocarrois, a local take on empanadas, or cool off in the quiet gardens and medieval ruins of the 10th-century Arab Baths.

Barcelona is bursting at the seams with culture and adventure. Marvel at modernist facades designed by celebrated Catalan architect Antoni Gaudí. Meander along the whimsical garden pathways of Park Güell. Take a chef-led Catalan cooking class, relish citywide views atop Montjuïc Hill— even swim with sharks at one of Europe’s largest aquariums.

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.
