The Netherlands' second-largest city and Europe's busiest port is home to some of the 20th and 21st centuries' most important architectural feats, which is particularly impressive when you consider that nearly all of Rotterdam was razed to the ground during World War II. Sometimes referred to as "Manhattan-on-the-Maas," the city lives up to its reputation as a forward-looking metropolis with fascinating design and some of the Netherlands' finest museums and most trendy shops.

Marvel at buildings by starchitects Rem Koolhaas and Norman Foster or get lost in the maze of gabled homes in historic Delfshaven, the point from which the Pilgrims set sail for the New World aboard the Speedwell in 1620. In the postwar years, Rotterdam has also become one of the most diverse cities on the continent as waves of migrants from elsewhere in Europe, North Africa and Turkey have come to work in the shipping industry, concentrated here thanks to the city's location on the deltas of the Rhine and Maas rivers. With its sweeping harbor and massive Europoort, the city has quickly grown to become the largest port in all of Europe.

Not a fjord in the geological sense, the Oslo Fjord is actually a vast expanse of water stretching south from the Norwegian capital for nearly 100 kilometers (62 miles). Almost half of Norway's population lives within an hour's drive of the fjord, so there's plenty to see along the shoreline, from islands and skerries to major towns and cities.

The picturesque coastal town Drøbak marks the entrance to the inner Oslo Fjord, where the waterway narrows and the islands are increasingly inhabited. Seagulls, oystercatchers, terns and geese are commonly sighted along these waters, as are countless fishing vessels.

The Oslo Fjord region is the warmest part of Norway, and on summer days locals dash to their boats to make the most of the sunshine. Many Norwegians own distinctive wooden cabins on the coastline or islands. The agreeable climate has attracted settlers since the days of the Stone Age and Bronze Age: Some of the world's best-preserved Viking ships were discovered on these shores.

The fjord was a strategically important waterway in World War II, and as such, historical monuments and former military installations are commonplace.

Oslo, Norway's capital, blends history with modernity. This vibrant city features top museums, modern architecture, and Viking heritage. Highlights include the Oslo Opera House, Nobel Peace Prize sites, and Vigeland Sculpture Park. Explore via hop-on-hop-off buses or fjord tours for a diverse array of experiences. Surrounded by the Oslo fjord, hills, and parks, Oslo is a must-see destination.

Whatever you do in Sandnes or nearby Stavanger, you're in for a fantastic time.

Norway's Sognefjord is the longest and deepest fjord in the world. Imagine 205 majestic winding kilometers (127 miles) of beautiful villages, centuries-old architecture including wooden stave churches, towering mountains with snow-covered peaks, cascading waterfalls and panoramic views. It is also a region known for its traditional food, folklore, music and rich culture. Set in the southern part of the country, centrally located at the heart of Fjord Norway (as the region is known), the fjord reaches depths of more than 1,308 meters (4,291 feet). It also soars to the sky, with rugged cliffs rising to more than 1,700 meters (5,577 feet). This is nature at its most dramatic. In fact, one of the Sognefjord's arms, the Nærøyfjord, is on UNESCO's World Heritage List. The Urnes Stave Church, which was build around 1130 is also included on UNESCO's World Heritage List. As the poet John Keats once wrote, “The poetry of earth is never dead,” and within the Sognefjord lie many sonnets of life. Be inspired by its treasures. All you have to do is sit back and watch the spectacular wonder of this destination.

Surrounded by steep hills and stunning waterfalls, Skjolden is located at the head Sognefjord--the world's longest navigable fjord. Visit Urnes Stave Church, the oldest stave church found in Norway, included on UNESCO’s World Heritage list, and take a hike in Jostedalsbreen National Park for views you'll never forget.

A stop in Amsterdam offers the chance to explore the sights of one of Europe's most colorful, dynamic and historic cities—one with a well-earned reputation as a laid-back and inviting place for people of all stripes. Visitors are naturally drawn to the historic city center where you'll find some of the world's top art museums, including the Rijksmuseum and the Van Gogh Museum. And at Dam Square, the Amsterdam's largest public square, you can tour the Royal Palace before continuing to the tourist attractions on the Canal Belt. The iconic network of waterways that surrounds the downtown area offers a picturesque backdrop for sightseeing by bike or canal boat. Be sure to visit the floating Bloemenmarkt to peruse famed Dutch tulips, and take time to wander and window-shop among the narrow lanes of de Jordaan. And you won’t have to look far in Amsterdam to find delicious Dutch treats along the way. Just duck into a cozy brown café to sample a plate of bitterballen with mustard and a beer, and grab a gooey sweet stroopwafel from a street vendor as you stroll.
