11 Night Cruise sailing from Lisbon to Barcelona aboard Crystal Serenity.

At 68,000 tons and capable of serving 1,080 guests, Crystal Serenity-is the largest ship in the fleet. However, like her sister ships, she still maintains one of the highest space-per-guest ratios at sea, so you'll never feel crowded. Featuring many of the same popular public spaces as Crystal Harmony and Crystal Symphony, Crystal Serenity also serves up innovation in the form of new dining venues like Tastes, Silk Road and The Sushi Bar, The Studio, and 85% of staterooms with private verandahs.

Highlights of this cruise:

Lisbon
Cosmopolitan Lisbon was the center of the world's last great colonial empire. Today the city nostalgically reveres its imperial past while adapting to Portugal's role as a member of the European Economic Community. Although located on the Atlantic coast, Lisbon has the soul of a Mediterranean city with Moorish castles, pastel and white buildings, orange-tiled roofs and luminous blue skies. Set amid the hills and valleys of the northern shore of the River Tagus, it is one of the loveliest capitals in the world.

Madeira/Funchal
The sub-tropical island of Madeira, often called the "Garden of the Atlantic," was the favored retreat of Sir Winston Churchill. This blissful island is a wonderland of rugged mountains, colorful flowers and ornate architecture.

Once ashore, enjoy browsing through local shops that boast an array of intricate embroidery, vibrant tapestries and detailed wickerwork. Feel free to sample the famed Madeira wine while relaxing in one of the island's numerous cafés.

Arrecife
The capital city of Arrecife, which means "reef" in Spanish, was named after the many volcanic rock reefs and islets along the coast that form the city's magnificent seafront promenade. While it originated in the 15th century as a small fishing harbor, the city is now an urban metropolis, as well as the island's main commercial center. The primary pedestrian shopping street, Calle Léon y Castillo, hosts a wide range of shops and cafes, and the city's hub is concentrated around El Charco de San Gines, a lagoon surrounded by fishermen's houses.

Agadir
A popular destination for sun-worshippers, Agadir is the center of the Barbary Coast's chic resort area and enjoys a lovely warm temperature year-round. A modern city, Agadir was completely rebuilt after a devastating earthquake struck in 1960. In sharp contrast, the nearby antique city of Taroudant makes a pleasant destination for explorers.

Casablanca
Centuries-old Casablanca, Morocco's largest city and principal port, lies on the Atlantic coast of North Africa. Awaiting your discovery is a timeless blend of Arabic culture and French sophistication, as seen by the imposing administrative buildings that recall years of colonial influence. Although the spirits of Bergman and Bogart still linger in the narrow alleyways of the old Medina, this gleaming white city has a firm grasp on the 21st century. Today, it encompasses broad palm-lined boulevards, attractive public parks and soaring high-rises. Bargain-filled souks are reminders of mysterious Africa and shopping aficionados will delight in scouring narrow alleyways for great buys in leatherwork, pottery, carved woodwork and Moroccan rugs.

Barcelona
Barcelona, capital of Catalonia, is a celebration of history and heir to Greek, Phoenician, Roman, Carthaginian, Gothic and Arab cultural legacies. Since it is nearly as close to Rome, Geneva and Munich as it is to Madrid, Barcelona has long been the Spanish link to Western Europe. It was the home of Picasso, Miró, Dali, Casals and Gaudí and has been described as a Mediterranean Manhattan, a cosmopolitan experimental center for political ideas and artistic movements. In addition to its abundance of artistic and architectural treasures, Barcelona serves as the gateway to one of the world's most impressive mountainside enclaves at Montserrat. Discover the secret legends of the Black Virgin and the alluring chants of monastic life high atop the Catalonian plains. Barcelona's ancient city walls and the narrow crooked streets of the town's old section are laid out for your discovery. You will find that Barcelona has something for everybody.
