Day 1 Amsterdam, Netherlands

Amsterdam combines the unrivaled beauty of the 17th-century Golden Age city center with plenty of museums and art of the highest order, not to mention a remarkably laid-back atmosphere. It all comes together to make this one of the world's most appealing and offbeat metropolises in the world. Built on a latticework of concentric canals like an aquatic rainbow, Amsterdam is known as the City of Canals—but it's no Venice, content to live on moonlight serenades and former glory. Quite the contrary: on nearly every street here you'll find old and new side by side—quiet corners where time seems to be holding its breath next to streets like neon-lit Kalverstraat, and Red Light ladies strutting by the city's oldest church. Indeed, Amsterdam has as many lovely facets as a 40-carat diamond polished by one of the city's gem cutters. It's certainly a metropolis, but a rather small and very accessible one. Locals tend to refer to it as a big village, albeit one that happens to pack the cultural wallop of a major world destination. There are scores of concerts every day, numerous museums, summertime festivals, and, of course, a legendary year-round party scene. It's pretty much impossible to resist Amsterdam's charms. With 7,000 registered monuments, most of which began as the residences and warehouses of humble merchants, set on 160 man-made canals, and traversed by 1,500 or so bridges, Amsterdam has the largest historical inner city in Europe. Its famous circle of waterways, the grachtengordel, was a 17th-century urban expansion plan for the rich and is a lasting testament to the city's Golden Age. This town is endearing because of its kinder, gentler nature—but a reputation for championing sex, drugs, and rock 'n' roll does not alone account for Amsterdam's being one of the most popular destinations in Europe: consider that within a single square mile the city harbors some of the greatest achievements in Western art, from Rembrandt to Van Gogh. Not to mention that this is one of Europe's great walking cities, with so many of its treasures in the untouted details: tiny alleyways barely visible on the map, hidden garden courtyards, shop windows, floating houseboats, hidden hofjes(courtyards with almshouses), sudden vistas of church spires, and gabled roofs that look like so many unframed paintings. And don't forget that the joy lies in details: elaborate gables and witty gable stones denoting the trade of a previous owner. Keep in mind that those XXX symbols you see all over town are not a mark of the city's triple-X reputation. They're part of Amsterdam's official coat of arms—three St. Andrew's crosses, believed to represent the three dangers that have traditionally plagued the city: flood, fire, and pestilence. The coat's motto ("Valiant, determined, compassionate") was introduced in 1947 by Queen Wilhelmina in remembrance of the 1941 February Strike in Amsterdam—the first time in Europe that non-Jewish people protested against the persecution of Jews by the Nazi regime.

Day 3 Kristiansand, Norway

Nicknamed "Sommerbyen" ("Summer City"), Norway's fifth-largest city has 78,000 inhabitants. Norwegians come here for its sun-soaked beaches and beautiful harbor. Kristiansand has also become known internationally for the outdoor Quart Festival, which hosts local and international rock bands every July. According to legend, in 1641 King Christian IV marked the four corners of Kristiansand with his walking stick, and within that framework the grid of wide streets was laid down. The center of town, called the Kvadraturen, still retains the grid, even after numerous fires. In the northeast corner is Posebyen, one of northern Europe's largest collections of low, connected wooden house settlements, and there's a market here every Saturday in summer. Kristiansand's Fisketorvet (fish market) is near the south corner of the town's grid, right on the sea.

Day 4 Aarhus, Denmark

Århus is Denmark's second-largest city, and, with its funky arts and college community, one of the country's most pleasant. Cutting through the center of town is a canal called the Århus Å (Århus Creek). It used to run underground, but was uncovered a few years ago. Since then, an amalgam of bars, cafés, and restaurants has sprouted along its banks. At all hours of the day and night this waterfront strip is abuzz with crowds that hang out on the outdoor terraces and steps that lead down to the creek.The VisitÅrhus tourist office has information about the Århus Passport, which includes passage on buses, free or discounted admission to the 12 most popular museums and sites in the city, and tours.

Day 5 Warnemünde, Germany

Warnemünde, officially a suburb of Rostock, is a quaint seaside resort town with the best hotels and restaurants in the area, as well as 20 km (12 miles) of beautiful white-sand beach. It's been a popular summer getaway for families in eastern Germany for years.There is little to do in Warnemünde except relax, and the town excels brilliantly at that. However, Warnemünde is a major cruise-ship terminal. Whenever there is more than one ship at dock, the town explodes with a county fair–like atmosphere, and shops and restaurants stay open until the ships leave at midnight. The city celebrates the dreifache Anlauf, when three ships dock simultaneously, with fireworks.

Day 7 Tallinn, Estonia

Estonia's history is sprinkled liberally with long stretches of foreign domination, beginning in 1219 with the Danes, followed without interruption by the Germans, Swedes, and Russians. Only after World War I, with Russia in revolutionary wreckage, was Estonia able to declare its independence. Shortly before World War II, in 1940, that independence was usurped by the Soviets, who—save for a brief three-year occupation by Hitler's Nazis—proceeded to suppress all forms of national Estonian pride for the next 50 years. Estonia finally regained independence in 1991. In the early 1990s, Estonia's own Riigikogu (Parliament), not some other nation's puppet ruler, handed down from the Upper City reforms that forced Estonia to blaze its post-Soviet trail to the European Union. Estonia has been a member of the EU since 2004, and in 2011, the country and its growing economy joined the Eurozone. Tallinn was also named the European City of Culture in 2011, cementing its growing reputation as a cultural hot spot.

Day 8 Helsinki, Finland

A city of the sea, Helsinki was built along a series of oddly shaped peninsulas and islands jutting into the Baltic coast along the Gulf of Finland. Streets and avenues curve around bays, bridges reach to nearby islands, and ferries ply among offshore islands.Having grown dramatically since World War II, Helsinki now absorbs more than one-tenth of the Finnish population. The metro area covers 764 square km (474 square miles) and 315 islands. Most sights, hotels, and restaurants cluster on one peninsula, forming a compact central hub. The greater Helsinki metropolitan area, which includes Espoo and Vantaa, has a total population of more than a million people.Helsinki is a relatively young city compared with other European capitals. In the 16th century, King Gustav Vasa of Sweden decided to woo trade from the Estonian city of Tallinn and thus challenge the Hanseatic League's monopoly on Baltic trade. Accordingly, he commanded the people of four Finnish towns to pack up their belongings and relocate to the rapids on the River Vantaa. The new town, founded on June 12, 1550, was named Helsinki.For three centuries, Helsinki (Helsingfors in Swedish) had its ups and downs as a trading town. Turku, to the west, remained Finland's capital and intellectual center. However, Helsinki's fortunes improved when Finland fell under Russian rule as an autonomous grand duchy. Czar Alexander I wanted Finland's political center closer to Russia and, in 1812, selected Helsinki as the new capital. Shortly afterward, Turku suffered a disastrous fire, forcing the university to move to Helsinki. The town's future was secure.Just before the czar's proclamation, a fire destroyed many of Helsinki's traditional wooden structures, precipitating the construction of new buildings suitable for a nation's capital. The German-born architect Carl Ludvig Engel was commissioned to rebuild the city, and as a result, Helsinki has some of the purest neoclassical architecture in the world. Add to this foundation the influence of Stockholm and St. Petersburg with the local inspiration of 20th-century Finnish design, and the result is a European capital city that is as architecturally eye-catching as it is distinct from other Scandinavian capitals. You are bound to discover endless engaging details—a grimacing gargoyle; a foursome of males supporting a balcony's weight on their shoulders; a building painted in striking colors with contrasting flowers in the windows. The city's 400 or so parks make it particularly inviting in summer.Today, Helsinki is still a meeting point of eastern and western Europe, which is reflected in its cosmopolitan image, the influx of Russians and Estonians, and generally multilingual population. Outdoor summer bars ("terrassit" as the locals call them) and cafés in the city center are perfect for people watching on a summer afternoon.

Day 9 Stockholm, Sweden

Stockholm is a city in the flush of its second youth. Since the mid-1990s, Sweden's capital has emerged from its cold, Nordic shadow to take the stage as a truly international city. What started with entry into the European Union in 1995 gained pace with the extraordinary IT boom of the late 1990s, strengthened with the Skype-led IT second wave of 2003, and solidified with the hedge-fund invasion that is still happening today as Stockholm gains even more global confidence. And despite more recent economic turmoil, Stockholm's 1 million or so inhabitants have, almost as one, realized that their city is one to rival Paris, London, New York, or any other great metropolis.With this realization comes change. Stockholm has become a city of design, fashion, innovation, technology, and world-class food, pairing homegrown talent with an international outlook. The streets are flowing with a young and confident population keen to drink in everything the city has to offer. The glittering feeling of optimism, success, and living in the here and now is rampant in Stockholm.Stockholm also has plenty of history. Positioned where the waters of Lake Mälaren rush into the Baltic, it's been an important trading site and a wealthy international city for centuries. Built on 14 islands joined by bridges crossing open bays and narrow channels, Stockholm boasts the story of its history in its glorious medieval old town, grand palaces, ancient churches, sturdy edifices, public parks, and 19th-century museums—its history is soaked into the very fabric of its airy boulevards, built as a public display of trading glory.

Day 10 Visby, Sweden

Gotland is Sweden's main holiday island, a place of ancient history, a relaxed summer-party vibe, wide sandy beaches, and wild cliff formations called raukar (the remnants of reefs formed more than 400 million years ago). Measuring 125 km (78 miles) long and 52 km (32 miles) at its widest point, Gotland is where Swedish sheep farming has its home. In its charming glades, 35 varieties of wild orchids thrive, attracting botanists from all over the world.

Day 11 Bornholm Island, Denmark

Day 12 Kiel, Germany

Known for the Kiel Canal and Kiel Week, the city boasts an important maritime history. Kiel is also a great place to sight-see, do some shopping and take part in one of the many festivals taking place there.

Day 13 Copenhagen, Denmark

By the 11th century, Copenhagen was already an important trading and fishing centre and today you will find an attractive city which, although the largest in Scandinavia, has managed to retain its low-level skyline. Discover some of the famous attractions including Gefion Fountain and Amalienborg Palace, perhaps cruise the city's waterways, visit Rosenborg Castle or explore the medieval fishing village of Dragoer. Once the home of Hans Christian Andersen, Copenhagen features many reminders of its fairytale heritage and lives up to the reputation immortalised in the famous song ‘Wonderful Copenhagen'.
