Spain, Provence & Italy: Rome, Portofino, Cinque Terre

Tarragona is a port on the Mediterranean Sea on the Catalonian coast to the southwest of Barcelona. The monks of the Grande Chartreuse established their liqueur distillery here in 1903, when they were forced to leave France. The city's archaeological museum has an outstanding collection of Roman statuary. The remains of a Roman amphitheatre and defensive walls are in the city, and a two-tiered Roman aqueduct is nearby. The Romanesque cathedral, construction of which was begun in the 12th century, is famous for its Gothic facade. Nearby are the beaches and resorts of the Costa Dorado.

Mediterranean cruise itineraries that include a stop at Valencia are well worth considering, as Spain's third-largest city -- with its lush parks, elegant tree-lined avenues, modernist City of Arts and Sciences, and gorgeous medieval Old Town -- is stylish, imposing and not to be missed. The bad news is that there's no way you can take in all that this fabulous city has to offer (including 34 museums and galleries) in just a day. The good news is that some of its greatest treasures lie within strolling distance of the Plaza del Ayuntamiento, which lies at the heart of the city. And the even better news is that Valencia is very tuned in to tourists. You'll find plenty of tourist information centres dotted around town, and before you go you can book a wide range of 'Get About' cards, valid for 24 or 48 hours, or even longer if you need it. These offer unlimited use of public transport as well as discounted entry to museums and other attractions, so it's well worth getting one to make exploring easy.

Relax and enjoy the facilities and entertainment onboard your ship. If the weather is good take some sun and sunbathe on the pool deck. Otherwise explore below deck the wide range of activities that will be available during the day. Perhaps you prefer to find a quiet spot and catch up on your reading.

La Spezia, Italy, lies southeast of Genoa on the Ligurian Sea's Riviera di Levante (Coast of the Rising Sun). Developed as a port even before Roman times, the original fishing village became a trading center for produce from around the world and, in particular, spices (hence, the name La Spezia, meaning spice). During the 13th century, the first set of fortress walls was built, only to be followed by a second defensive ring in the 1600s. Today, the city is Italy's main naval base, as well as a cruise port. In town, visitors can see remnants of the old city walls and discover the port's history at the Naval Museum. The Amedeo Lia Museum displays a private collection of paintings by Italian masters in a former convent. Archeological finds may be seen in the imposing Castle of San Giorgio; getting to the ancient watch tower by funicular is half the fun.

The capital city in the land of Leonardo, Michelangelo and the popes is today a living museum with gorgeous artwork, amazing architecture and inspiring ancient sites. At the same time, it's alive and vibrant in a 21st-century way. It's an unforgettable city to visit, and we'll warn you right now that once you've experienced it, you'll want to go back for more.

One of our favorite things to do there is walk and ogle. On a recent visit, we took one day to do the route from Vatican City and St. Peter's Basilica -- with its jaw-dropping art, statuary, and religious significance -- to Via del Corso, where our quest for the latest Italian fashions was more than fulfilled amidst the well-dressed crowd of Roman shoppers. The next day, we went on an ancient history quest past ruins and columns, traversing the same streets Julius Caesar strode (and rode) to the Colosseum, where gladiators once battled. Walking on, we were awed by the Pantheon, the well-preserved ancient symbol of Rome and now a great hangout spot.

First-time visitors, many envisioning Rome as big and congested, will be surprised by the scenic layout, with its famous seven hills and the Tiber River running through the city. (Cleopatra famously made her grand entrance from the river.) And the senses may be shocked by the general energy, hustle and bustle. With cars, taxis and scooters roaring here and there, crossing the street can be a challenge. (Don't worry; there are quiet piazzas aplenty with lovely cafes where you can get away from it all and unwind.)

The food is, of course, wonderful -- we can't eat enough pasta -- and the spirit of la dolce vita (the good life) abounds. Whenever we do such a quest in Rome, we do regular gelato stops (try the yummy pine nut flavor) or coffee breaks. And the shopping scene serves up Prada, Gucci, Armani and more. (High style can be found in more affordable brands like Furla, as well.) What could be better than that?

No question, Rome has one of the world's most important collections of once-in-a-lifetime sights to see, including St. Peter's Basilica and the Sistine Chapel, the Colosseum, the Pantheon, the Forum and on and on and on. And for those historic monuments alone, the city is worth a visit.

But if you're on an itinerary where Rome is just a port of call for the day, you won't see everything. Either resign yourself to that fact, or book a tour that will at least drive you by the main sights. Be aware the port for Rome, Civitavecchia, is about 1.5 to 2 hours from the city. (There is decent train service.) If you're beginning or ending your cruise there, plan to stay at least a couple of nights to explore the Eternal City; it's likely to steal a piece of your heart. Make sure to drop a coin in Trevi Fountain, which is said to assure you'll come back again.

Sometimes, cities are lucky enough to reinvent themselves. Genoa, given short shrift in travel guides 20 years ago, has undergone a striking renaissance since 1992, when it hosted an international expo to commemorate the 500-year anniversary of the discovery of the New World. Nowhere is that benefit more evident than at Porto Antico, the old port close to the marine terminal, where many of today's cruise ships now dock. What once was a seedy waterfront on Northern Italy's Mediterranean is now a charming blend of old and new structures, featuring cafes, shops, a movie complex, a maritime museum, a spectacular play and cultural center for kids and, most importantly, the largest aquarium in Europe. From a distance, the Genoa cityscape -- climbing up a steep, green hillside from the Ligurian sea -- is awash in Mediterranean color: ochre, pink and red. It's a big town with more than 600,000 people, but it has a small-town feel and layout that make it imminently walkable. In fact, Genoa's foremost calling cards -- its historic center; the Piazza de Ferrari, where the Opera and Palace of the Doges are located; the chic shopping avenue, Via XX Settembre; and the largely pedestrian-only streets that hug the Cathedral of San Lorenzo -- are all within a 10- to 20-minute walk of Porto Antico. Genoa, or Genova in Italian, has a rich history dating back to ancient times, but it's probably best known for Christopher Columbus, its most famous native celebrity. It has long been associated with the arts, and in 2004 the European Union designated Genoa as a European Capital of Culture. In 2006, a mid-16th century district on Via Garibaldi that houses an architecturally important ensemble of Renaissance and Baroque palaces was included on UNESCO's World Heritage List. Genoa typically serves as a port of embarkation or disembarkation, so it isn't often given high priority as a shore excursion. Our best advice? Enjoy a day here before or after your cruise. It's worth it.

Marseille, gateway to Provence, is France's largest port and second largest city, with a vast history stretching back more than 2,000 years to its foundation by the Greeks in the 6th century BC. While much of the city is urban sprawl, it has a spectacular setting between dramatic limestone hills and the Mediterranean, and the once-industrial streets now feature stylish shops and cutting-edge art galleries, thanks to investment from its role as European Capital of Culture 2013. Most cruisers make a beeline for Le Vieux Port, a buzzing, picturesque harbour lined with boutiques, restaurants and cafes. This district attracts an eclectic crowd, from local fishermen to millionaires venturing ashore from James Bond-style mega-yachts. All gather to soak up Le Vieux Port's charming atmosphere, browse its bustling markets and tuck into a bowl of Marseille's classic signature dish, bouillabaisse (a rich fish stew).

Tarragona is a port on the Mediterranean Sea on the Catalonian coast to the southwest of Barcelona. The monks of the Grande Chartreuse established their liqueur distillery here in 1903, when they were forced to leave France.
