Highlights of this cruise:

Barcelona, Spain
On the northeast coast of Spain, overlooking the Mediterranean, Barcelona is a vibrant port city, packed with centuries of iconic art and architecture—Gaudí and Picasso both called it home—and lined with sunny white-sand beaches. Explore the Catalan capital's tourist attractions and historic neighborhoods, Modernisme and world-renowned art museums, galleries and local crafts shops—some of which are centuries old and stock traditional Catalan wares. After you see the sights, there are lively tapas bars around every corner where you can stop for a drink, a café amb llet (Catalan for espresso with steamed milk) or a snack, no matter the hour. Green spaces for picnics, long walks and respite from the hustle and bustle are scattered throughout Barcelona's attractions: There's Gaudí's mosaic-decorated park, a neoclassical maze at the Laberint d'Horta, as well as plenty of high places (mountains, monuments and edifices) where sightseeing visitors can take in the view. A short trip from Barcelona by car or train, luxury outlets, cava wineries, a mountaintop abbey and the sandy beaches of the Mediterranean coast await.

Monte Carlo, Monaco
The tiny and wealthy principality of Monaco, ruled by Prince Albert II, is dominated by the attractions in the resort quarter, Monte Carlo, with its casino, internationally acclaimed Opera House and the Triangle d’Or shopping area. The cliffs of Le Rocher de Monaco rise above the Mediterranean, the strategic stronghold of the Grimaldi family of Genoa who assumed power of this unstable region in 1297. The principality was a quiet backwater until the 1850s when trains put the sun-soaked destination within easy reach of affluent French and British travelers looking for an escape and relaxing things to do. Prince Charles III quickly understood what it would take to seduce the new tourists, and created a Belle Epoque resort featuring the mythic Casino de Monte-Carlo. Sitting on the coast like a precious gemstone, Monte Carlo and Monaco still draw an international jet-set crowd. The Palace commands from Monaco-ville, called Le Rocher by locals, and high-rises make the most of precious land with public elevators in lieu of sidewalks in this steep country. Superyachts fill the port, ultraluxury cars dominate the road and outrageous jewels sparkle under the night sky in an eternal promise that in some places, fairy tales really do come true.

Livorno (Florence/Pisa), Italy
The Renaissance-era port city of Livorno, Italy, gateway to Pisa, Florence and the rest of the attractions of Tuscany, is characterized by its solid 16th-century Fortezza and the charming canal network known as Venezia Nuova. It’s also famous for cacciucco, a spicy fish stew. To the north of Livorno, not far from the mouth of the river Arno, lies Pisa, an attractive university city best known for its Leaning Tower. Some 60 miles to the east, and also set on the Arno, is Florence, Tuscany's capital. The concentration of artistic treasures and cultural things to do in Tuscany, from museums and cloisters to bridges and chapels, is second to none—but there is lots more besides sightseeing in Florence. The food and drink culture in Florence takes in tripe stands and hole-in-the-wall wine bars as well as embracing gourmet restaurants and plenty of down-to-earth family-run trattorias. The shopping scene offers the designer stores of Via Tornabuoni and Via Roma, but there are plenty of quirky, independent boutiques too. And then there is Florence’s traditions of leather work, marbled paper, book-binding and furniture restoration. Explore the sights of the arty Oltrarno neighborhood for artisan workshops, great cafés, bars and restaurants and an authentically Florentine atmosphere.

Civitavecchia (Rome), Italy
Rome is both a modern bustling city and an ancient open-air museum. You can walk in the footsteps of emperors, have coffee in Renaissance piazzas and see contemporary art all in one afternoon. Your sightseeing time in Rome begins at the nearby port of Civitavecchia, a seaside town with roots that stretch back to the Etruscan era. Take note of the Forte Michelangelo (both Bramante and Michelangelo had a hand in its design), and the lungomare, a lively stretch along the sea with beach clubs, bars and restaurants. Once in the Eternal City you can fill your day with museums, churches, archaeological sites, traditional trattorias, artisan shops and, of course, gelato. The Colosseum and the Vatican Museums are Rome's superstar attractions, but there are plenty of quieter gems to explore. For food lovers there are the markets in Campo de' Fiori or the slightly farther flung Testaccio. The hip neighborhood of Monti, next to the Colosseum, has a vibrant piazza scene and boutique shopping, while the Villa Borghese offers a green oasis with a view towards Saint Peter’s Basilica and the masterpiece-filled Galleria Borghese. Although Rome might not have been built in one day, you'll certainly be able to see the highlights and top things to do in Rome in 24 hours.

Dubrovnik, Croatia
On the southern end of Croatia's Adriatic coast, Dubrovnik staked its claim to glory during the 450 years it existed as the independent Ragusan Republic, shoulder to shoulder with mighty forces like Venice and the Ottoman Empire. Once a renowned seafaring, shipbuilding and trading center, today it's an enchanting tourist destination. Dubrovnik seduces sightseeing visitors with its polished (and very clean!) limestone streets, theatrical architecture, charming
café, welcoming restaurants and distinctive shops along scenic side streets. The natural backdrop, much of which is protected, consists of pine and cypress forests and the shimmering Adriatic, dotted with uninhabited islands. Visitors quickly discover that the wider Dubrovnik area is just as striking as its main attraction—the Old Town. A wander around the historic heart of Dubrovnik can hit the main sights, but take it a step further (or a staircase further, really), and you'll see that people do still live in the historic quarter, even though its polished streets make it look like a museum. You may catch the sound of a piano from the High School of Music and Arts, or hear the Dubrovnik Symphony Orchestra rehearsing in the Revelin Fortress, or encounter school kids on a break. Life unrolls as you stroll past.

Kotor, Montenegro
Cruising into the Bay of Kotor, you'll be wowed by the dramatic beauty of this coastal Montenegrin town. Dreamy seafront villages are set to a backdrop of mountains plummeting into the Adriatic Sea, while the stone labyrinth of the Old Town is filled with medieval architecture and historic monuments—as well as the narrowest street in the world. The area only became part of Montenegro after WWII, and as such has a very different history to the rest of the country. Kotor escaped Ottoman rule and developed as an important Venetian trading post, before being conquered by the Austro-Hungarian Empire, France and Russia. The city pays tribute to this dynamic history with Venetian gates, Napoleon's theater and Austrian prisons all waiting to be discovered. There's a reason it was named a UNESCO World Heritage Site. The cruise ship dock is across the street from the Sea Gate, the main entrance to the Old Town, while a conveniently located taxi stand by the harbor gates allows for easy exploration of the region.

Venice, Italy
"When I went to Venice, my dream became my address," wrote Lord Byron, just one of many famous figures who found a haven in this fantasy city. This enchanted land was built on stilts, set into the water by ancient Venetians seeking refuge from the harsh realities of landlocked life. And Venice, Italy still offers a palpable feeling of escape from the real world today. When you cruise into the lagoon and step onto what passes for solid ground, you'll still be very much on the water. Venice is a floating labyrinth of reflections, with mirror and glass sights everywhere, from glorious Venetian architecture echoed in the canal waters to the marble palaces that shimmer in the sky. And although Carnivale is only held once a year, being in Venice on any day is like going to a festival with plenty of vibrant things to do and attractions to see. Locals seem to love the many sightseeing visitors who arrive each year, and Venice will openly reveal her charms even to those who are only here for a few hours, an afternoon or a magical evening.

Korcula, Croatia
Croatia’s sixth-largest island—once known as Melaina Korkyra (Black Korkyra) because its vast oak forests reminded Greek settlers of Corfu—is covered in pine trees, olive groves and vineyards. As you glide down the Strait of Pelješac, admire the peninsula’s dramatic karst slopes dropping off into the Adriatic Sea and the 19 islets of the archipelago around the canal. Korčula Old Town is the island’s treasured highlight and a UNESCO World Heritage Site candidate. Its stone architecture and historic ambiance reflect almost four centuries of Venetian rule, with towered gates, lion statues, magnificent palazzos and elaborate stonework peppering the charming streets. Venturing out of the Old Town, you will encounter historic villages, picturesque bays, waterfront promenades and welcoming locals. Korčula is one of the last places on earth where knightly games like the Moreška dances are still regularly performed and where medieval fraternities still keep up their centuries-old traditions. The island truly is a treasure trove of history, nature and serenity.

Thira (Santorini), Greece
Santorini, the jewel in the crown of Greece's Cyclades, is best known as the island with the giant volcanic caldera at its heart. All but the largest ships can anchor here in this stunningly scenic bay. Cruise visitors who come for an afternoon or a day can immerse themselves in the art, food and legendary wines of this island that some believe may have been the site of the lost civilization of Atlantis. On Santorini you can do as Dionysus, the Greek god of wine, would do and sample the island's wonderful wines or play Indiana Jones and explore the archaeological treasures of ancient Thera. Santorini's pleasures will likely leave you with a taste for more and planning your return.

Kusadasi (Ephesus), Turkey
Kusadasi in Turkey is the gateway to one of the most legendary cities of the ancient world: Ephesus. St. Paul preached in its Great Theater, while the facade of the Celsus Library survives as a testament to the city’s role as a center of learning and culture. Not far from Ephesus, the Temple of Artemis (also known as the Temple of Diana), one of the Seven Wonders of the ancient world, once stood, drawing pilgrims from around the Mediterranean. While it no longer stands, it is possible to walk amongst its foundations and the remains of its towering columns. Other historic sites can also be found nearby: The House of Mary is believed to be the home of Jesus’s mother at the end of her life, and the Basilica of St. John, constructed in the 6th century, marks the location of his tomb. (Like Mary, he spent his final years in Ephesus.) Nearby, the Selcuk fortress reflects the period of Byzantine and Ottoman control of the region. From ancient wonders to holy sites, there are few ports in the Mediterranean as magical as Kusadasi, and a day here is a day spent in the company of some of antiquity's greatest figures.

Piraeus (Athens), Greece
No modern metropolis is more steeped in myth than Athens, Greece. From the gritty port of Piraeus—gateway to Greece’s fabled isles—to the Parthenon—eternal symbol of Western civilization—Athens has attracted adventurers and classicists for centuries. This heritage is still very much alive for modern visitors sightseeing in Athens: ancient stadiums and temples dwell alongside apartment blocks, modern performances are staged in the marble amphitheaters where Greek drama was born and millennia-old monuments are scattered in the archaeological park that circles the Acropolis. One of the world’s oldest maritime powers, Athens is blessed with a balmy climate and stunning coastline. The seaside suburbs of Athens are scalloped with sandy beaches, fancy yacht clubs and glamorous beach bars. While the Athenian lifestyle is known for late-night dinners and dancing until dawn, the city shines brightly by day in the bustling markets, lively cafés and fascinating museums that illuminate Greece's past and present. Contemplate the magnitude of all that culture and ancient tourist attractions while marveling at the sun setting into the Aegean or rising over the Acropolis.
