24-Day Arctic Circle, Northern Lights & Iberian Peninsula

Often called the gateway to Europe, the port city of Rotterdam is full of old-world charm. The harbor offers amazing views and a maze of wharves and canals, along with towering spires make for a beautiful sight. Take a stroll and duck into one of the pubs or eateries along the way. Only three pre World War II buildings in the city centre have survived and are worth a look - city hall, St. Laurence church and the White House. Explore the Museum Boymans van Beuningen, which houses a unique collection dating from the 14th century, or the Museum Voor Volkenkunde - home to ethnological exhibits. Exquisite architecture can be seen in many areas of Rotterdam, most notably in the Delfshaven quarter of the city - where 18th century houses are on display. For a laugh, check out Kijk-Kubus, an upside-down house.

Ålesund, a quaint fishing town of approximately 45,000 in western Norway, has been called Norway’s most beautiful city. A fire in 1904 destroyed much of it, resulting in the town being rebuilt in the Art Nouveau style—also known as Jugendstil—that was popular around the turn of the 20th century. A year after the fire, Norway gained its independence from Sweden, which led to a campaign to build a "Norwegian town" to mark the creation of the new nation. The colorful buildings feature castlelike turrets and spires with intricate facades of ornamental flowers, gargoyles and Viking-inspired decorations. Bordering the Norwegian Sea, this area is also famous for its mountain ranges and fjords. For those looking for a more active visit, Ålesund offers great hiking, mountain biking and kayaking. One of the highlights is climbing the 418 steps that lead up Mount Aksla for a spectacular view of the city and the Sunnmøre Alps. Nearby is the Geirangerfjord, a UNESCO World Heritage Site known for its beautiful waterfalls. This is also home to Atlanterhavsparken, or the Atlantic Sea Park, one of the largest aquariums in Europe.

Although a popular cruise destination, Norway’s Viking capital is often overlooked by other travelers in favor of Oslo and the fjords. Yet Norway’s third-biggest city has plenty to offer those who make the time to explore. The compact city center, enclosed by the Nidelva River, is easy to get around on foot. Within a couple of hours you can explore the main downtown sights and still have time for a bite to eat. The medieval Gothic grandeur of the Nidaros Cathedral is a must-see, as is the historic riverside Bakklandet neighborhood just a few steps away. Despite so much history, the city has a youthful feel to it, thanks to the dominance of NTNU, Norway’s leading technology university. The presence of thousands of students means Trondheim scores well on café culture and shopping. Music lovers will feel right at home here. The Rockheim and Ringve museums chronicle the importance of music to the city’s past, while vinyl stores and basement bars showcase the present.

Alta, a 2½-hour drive from Hammerfest, is the commercial center at the head of Altafjord -- home to some 12,000 inhabitants.

Beautiful Bergen, Norway’s second-largest city, is one of the most popular ports of call on a cruise up the fjords. Step off the ship into the medieval Bryggen wharf area, a UNESCO World Heritage Site since 1979, where small boats line the harbor and wooden gabled buildings stand proud along the waterfront. Bergen’s rich maritime tradition goes back nearly 1,000 years, including the years the town played an important part in the Hanseatic League, the trading empire that dominated maritime commerce in the region between the 14th and 18th centuries. The city is one of Europe’s oldest settlements, and its cobblestone streets and narrow alleyways lead to emerald-green parks, medieval cathedrals and stone fortresses that kept enemies at bay centuries ago. It's also eminently walkable, with historic buildings and excellent markets selling everything from fish and produce to trinkets and souvenirs. Surrounded by mountains and thick forest, and sitting halfway between Geiranger to the north and Stavanger to the south, Bergen offers plenty to do outside the city too. Whether you sign up for a guided excursion or venture out on your own, you’ll be sure to fall in love with Bergen.

Although part of the United Kingdom, Shetland’s roots are as much Norse as Scottish. This is reflected in the archipelago's many archaeological sites, cultural events and a unique dialect that borrows heavily from Old Norse. Although economically driven by energy, in particular the North Sea oil industry and a growing number of wind farms, Shetland’s heritage of fishing and textile production lives on. Tradition also drives the islands’ main festivals, including the world-famous Viking-themed Up Helly Aa festival of fire held every January, and smaller folk festivals held throughout the year. Located midway between Scotland, Norway and the Faroe Islands, the archipelago is home to diverse animal life including the iconic Shetland ponies, easily recognizable by their distinctive short legs and heavy fur coats. Get a closer look at the ponies and the unique black Shetland sheep on the scenic drive to the remarkable Bronze Age archaeological site at Jarlshof. If you choose to linger in Lerwick, head to Commercial Street for the best independent shops and places to eat. A surprising number of musicians, writers and filmmakers make Shetland their home. The new Mareel center for visual and performing arts is testament to the growing importance of the arts community to the Shetland way of life.

There are more than two millennia of history to embrace in this port city in Spain's southeastern Murcia region. While Cartagena is famously home to the second-largest Roman amphitheater on the Iberian Peninsula, the city is much more than just spectacular ancient ruins. In addition to Cartagena’s architecture—along with that amphitheater, there are striking Art Nouveau buildings, neoclassical churches and ultramodern edifices throughout the city—you’ll find many opportunities to shop for local and regional artisan wares. In the city, investigate the restored medieval fortress looking out on the bay from the city’s highest point. Or take a short trip by car or bus to the historic Agrupa Vicenta Mines, the remarkable palm forest at Elche and the holy city of Caravaca. And the food of sunny Murcia! Friendly tapas bars with breezy terraces invite lingering over drinks, coffee or snacks. The local restaurants offer more than typical Spanish tapas on the menu—michirones (a spicy Murcian bean stew) and local spins on paella are widely available and worth a try. Grilled octopus, fried calamari, mussels and the freshest fish are some of the tasty benefits of the city’s perch beside the sea.

Famous for paella at Pepica's, favorite of Ernest Hemingway when he came to Valencia for bullfight festivals.

On the northeast coast of Spain, overlooking the Mediterranean, Barcelona is a vibrant port city, packed with centuries of iconic art and architecture—Gaudí and Picasso both called it home—and lined with sunny white-sand beaches.

After you see the sights, there are lively tapas bars around every corner where you can stop for a drink, a café amb llet (Catalan for espresso with steamed milk) or a snack, no matter the hour. Green spaces for picnics, long walks and respite from the hustle and bustle are scattered throughout Barcelona's attractions: There's Gaudí's mosaic-decorated park, a neoclassical maze at the Laberint d'Horta, as well as plenty of high places (mountains, monuments and edifices) where sightseeing visitors can take in the view.
