Copenhagen
With its nearly endless daylight, summer is the most popular time to visit. The city's myriad parks, canals, and cafes are packed with people, while its beaches offer an ideal place for a relaxing BBQ. But the city has fantastic festivals year-round, a lovely Christmas market tradition, and relatively mild winters. To avoid the clouds and catch the Danes when they're at their most vibrant, consider a visit in late spring as the marguerite daisies begin to bloom and the Danes celebrate the end of the long winter nights.
