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.

Rising behind the wide curve of its bay with brooding Mount Vesuvius and the deep blue sea as a backdrop, Naples, Italy enjoys a magnificent natural setting. It is the third-largest city in Italy after Rome and Milan, and arguably the most colorful and seductive of them all: Splendor and squalor live side by side in 21st-century Naples, and the mix is intoxicating. Cruise to Naples, home to world-class museums and attractions. Naples has something for everyone – superb restaurants, eclectic shopping, a thriving contemporary art scene and an edgy and vibrant street life. But once you’ve had enough of the pounding traffic and jostling crowds while sightseeing in Naples, there are endless opportunities for exploration further afield. The celebrated Roman ruins of Pompeii and Herculaneum, both victims of Vesuvius’ devastating 79 C.E. eruption, lie just south of the city. Explore Naples’ history or take a short ride over to the island of Capri on a Naples shore excursion. The delightful town of Sorrento and the magnificent scenery of the Amalfi Coast are also within easy reach, and the dolce vita glamour of Capri—not to mention the healing thermal waters of Ischia—are a short hydrofoil hop from the mainland. Naples cruises offer a perfect mix of cultural and natural attractions.

When you embark on a cruise to Rome with Holland America Line you experience its bustling modernism along with its rich history. 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.
