14 Night Transatlantic Cruise

The hub of Spain's southern Costa del Sol, Málaga is the picture of paradise. Scale the hilltop to dramatic La Alcazaba, the sandy-colored Moorish fortress dating back to the 11th century that overlooks this ancient seaside city. Sun yourself on the idyllic beaches of Caleta and Malagueta, taking in views of the mountains across the bay. See the eccentric works of modernist master Pablo Picasso, the city's most famous native son, at the Picasso Museum. Cruise to Málaga and immerse yourself in baroque and renaissance architecture at Málaga Cathedral, with its elaborate arches and stone reliefs depicting the saints, or turn the clock back to the first century A.D. at the ruins of the Roman Theatre.

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.

The Spanish island of Mallorca offers towering mountains and dramatic cliffs rising over clear, blue water — but its hidden gem is Palma de Mallorca, the island's capital and largest city, where you'll find quaint historic streets, Gothic castles and gastronomic delights. Cruise to Palma de Mallorca and check out one-of-a-kind Palma Cathedral: The 14th-century Gothic spires of exterior contrast the modernist interior designed by in the early 1900s by Gaudi. See the circular courtyard and Arab-inspired arches of Castell de Bellver, and take in the fresh scent of the miles of pine forest that surround it. Or rent bikes and pedal east to Palma Beach, where you can soak in the sun on the white sands and clear waves.

France's oldest city, Marseille blends ancient charm with Provencal beauty. In the morning, head to the fish market Quai des Belges, where trade has been going on for more than 2,600 years — stroll along the promenades and 18th-century warehouses, and grab a cafe au lait and a melon tarte from one of the cafes on the ground floor. Cruise to Provence and check out the Basilique Notre-Dame de la Garde: Built in the 19th century in a neo-Byzantine style, its golden statue of the Virgin and Child dominates the Marseille skyline. Then, take in the modern architecture and Mediterranean cultural artifacts at the MuCEM art museum, or see the craggy limestone cliffs of Calanques National Park, a half-hour drive outside the city.

The northern Italian port city of La Spezia, on the border of Liguria and Tuscany, offers an ideal gateway to two of the country's most famous cities: Pisa and Florence. Just one hour by car or train will bring you to Pisa, where you can check out the white-stone arches of the city's famous leaning tower and its sister-structure, the Pisa Cathedral. Or spend your day in Florence, about two hours away by train: Climb to the top of the famous Duomo ("dome"), the nickname for the Italian Gothic Santa Maria del Fiore cathedral, for stunning 360-degree views of the city. Cruise to Florence to stroll through the San Lorenzo market with an espresso in hand and take in the smells of local spices and truffles as you people-watch.
