8 Night Northern City Escapes Cruise

Oslo combines the modern and the historical into a heady stew of Scandinavian cool. With a history that dates back to the Middle Ages, Oslo retains remnants of its past, with medieval ruins alongside charming wooden houses in the Old Town. At the same time, locals embrace their town's reputation as one of the world's most modern cities. The Opera House's striking design invites you to walk on the roof before you explore the sleek interior during your Oslo cruise. Don't miss the Munch Museum, a treasure trove of works by the artist behind "The Scream." Examine ancient ships up close at the Viking Museum. See Olso's quirky side at Frogner Sculpure Park, where you'll find whimsical art in a soothing green setting.

Copenhagen has come a long way from its early Viking days. Its historic center of Frederiksstaden has its share of castles and royal-era palaces— but it’s the modern, sleek Scandinavian design and playful, hygge spirit that sets Denmark’s capital apart today. Each neighborhood offers its own unique, exciting adventures. Explore the city’s seafaring past with a canal cruise under a network of bridges, or take a stroll along Nyhavn’s colorful quay. Peek in Kødbyen’s trendy art galleries and savor world-renowned Nordic cuisine in Christiania’s quirky cafes. Adventure comes in many forms in Copenhagen, from Baltic beaches to famous fairytales.

Known in German as Tor zur Welt — the Gateway to the World — Hamburg is Germany's most cosmopolitan metropolis. Come here to stand before architectural landmarks, like the towering neo-renaissance Hamburg Rathaus and the baroque Church of St. Michael. Cruise to Germany to experience the lively restaurant and bar scene along the River Elbe, and take in the maritime scenery of Hamburg Harbor, Europe's third-busiest port. Steep yourself in international influence in the Sankt Pauli district, which has a Chinatown that dates back to the 1890s. Or delight in the distinctly German character of Moenckebergstrasse, with its classic churches and old-school European vibe.

Rotterdam is Europe's biggest port and one of the Netherlands' great surprises. Hit hard by World War II, the city was rebuilt gradually from the 1950s to the '70s — today, it's a lively, thriving metropolis that's home to a diverse, multicultural population. Get a taste of what the city used to look like at the Old Harbour or Delfshaven, a historic marina that survived the 1940 bombardment. Then, visit one of the many top-class museums, such as Boijmans, Van Beuningen or the Kunsthal in Rotterdam's Museum Park. Take a gander at the extraordinary cube houses and the sparkling market hall. Cruise to Rotterdam to relax at the Kralingse Plas lake and park, and snap a photo of the windmills.
