Overlooking Lake Zürich and spanning the banks of the Limmat River, Switzerland's largest city is often cited as one of Europe's most livable. It is the country's financial heart, but its residents also embrace their natural surroundings, from soaring alpine peaks to the lake's shimmering waters. Zürich is home to a lively and impressive arts culture. The avant-garde Dada movement was born here in 1916 and two of its most important churches boast stained glass windows by Marc Chagall and Augusto Giacometti. More masterworks reside in the city's renowned Kunsthaus, including an enormous water lily painting by Monet.

Zürich offers much more than its reputation as a city of banking institutions. The Grossmünster is one of Zürich's most important landmarks and the center of the Swiss Reformation in the 16th century. Across the river lies Fraumünster, famed for its stained glass windows painted by Marc Chagall. Exclusive designer boutiques line the streets of Storchengasse alongside world-renowned chocolatiers and quaint, cozy cafés. The scent of delicious sweet treats and freshly baked gipfeliwaft through the air on every street corner.

Located where Switzerland, Germany and France meet, Basel reflects a fascinating blend of traditions. The city straddles the Rhine at the river's farthest navigable point, and an alluring cluster of old-town buildings huddles along the riverbank. Around Market Square, guild houses recall Gothic, Renaissance and baroque splendor; the red-sandstone Rathaus, or Town Hall, is the centerpiece. More than 40 museums of art and culture lend modern polish to its history-rich streets. And there is no more refined way to sample it all than over cheese fondue or croissants.

The largest port on the Upper Rhine, Strasbourg is the cultural center of France's Alsace region. Thanks to its location at the border of France and Germany, it boasts a convivial mix of cultural influences. The well-preserved old town is enclosed on all sides by the little Ill River, with sites so compact that it is easy to explore the "island” on foot. And there is plenty to explore: cobblestone streets lined with wooden houses and intersected by picturesque canals. Indulging in Alsatian café culture is central to any visit here; enjoy coffee and cake amid lovely half-timbered houses.

The quiet German town of Speyer lies on the west bank of the Rhine. The city features a Romanesque imperial cathedral, burial place of eight emperors including some of the most famous Holy Roman Emperors. Speyer was once a major Celtic center that traded hands several times between the Romans and the Huns. The term Protestant originated here at the Diet of Speyer in 1529, when 14 free cities of Germany and six Lutheran princes protested the Edict of Worms that had banned the writings of Martin Luther and labeled him a heretic and enemy of the state.

Mainz is part of the Rheinhessen wine region, Germany's largest wine region that is renowned for producing high-quality white wines, such as Riesling. Wine has long played a key role in the city's economy and culture, with numerous wine festivals and events throughout the year, including the Mainzer Weinmarkt and the Mainzer Weinwoche. The city is also home to the renowned Geisenheim University, which offers programs in viticulture and oenology. Mainz's wine culture and history continue to thrive today, with a strong emphasis on sustainability and innovation in winemaking.

The Rhine River flows through one of Germany's most scenic regions. As you sail its most picturesque stretch, the UNESCO World Heritage Site of the Middle Rhine, you will pass vineyard-blanketed hills whose steep slopes require vintners to pick grapes by hand, keeping a centuries-old tradition alive. Splendid castles line the banks, all of which have stories to share, and the Lorelei Rock presides at a dramatic curve in the river. This infamous river maiden mesmerized sailors with her song and lured them to their demise at her feet.

Perched on a hilltop above the city and the Moselle, a 1,000-year-old imperial castle is the signature landmark of Cochem. Its mighty rectangular keep and many small towers strike a dramatic pose against a curtain of green hills. In Cochem's lively Old Quarter, the market square boasts old timber-framed houses that overlook Martin's Fountain and the bay-windowed baroque Town Hall. In this historic center, the 15th-century St. Martin's Church and the Capuchin monastery, which now serves as an artistic and cultural center, are all beautifully preserved. Wine taverns along the river offer a "green wine,” a very young wine.

One of Germany's most treasured cities for its rich history, Trier was once the regional capital of the Holy Roman Empire. After Emperor Constantine the Great had a vision of Christ, he and his mother Helena built great churches and cathedrals here. A few still stand, the magnificent Romanesque Cathedral of Trier among them. The 20,000-seat amphitheater, the Roman Bridge and the massive Porta Nigra, the ancient city gate, are further relics of that time. Today, Trier is a picturesque town surrounded by forests and vineyards, known also as the birthplace of Karl Marx and as a vibrant university town.

Long a hub of French culture and cuisine, Paris is one of the most romantic destinations in the world. Over the centuries, Parisian culture has been built on the wings of inspiration. Music, film, architecture, literature, dance and the visual arts all have their brilliant place in the museums, theaters, bookstores and remarkably preserved buildings of this magnificent city. At the center of it all is the Champs-Élysées. With its inviting riverside promenade, graceful bridges and splendid views of all things Parisian, from the Eiffel Tower to the Louvre Museum.

One of the most pleasurable activities in Paris is whiling away the time in one of the city's outdoor cafés. Whether you are sipping a café au lait or a kir royal, there is no better way to feel like a Parisian. The hub of social and culinary life, cafés have been part of the city's fabric since the 1600s. During the 20th century, literary and artistic figures-such as Ernest Hemingway, Colette and Pablo Picasso-famously met over drinks to share their works and ideas. Today, thousands of cafés line the pavements and squares to connect with France's culture and history.
