Copenhagen celebrates Jul (as in "yuletide") with a Christmas crafts market and surfeit of light-bedecked Christmas trees in the city's famed historic amusement park, Tivoli Gardens. Nearly four miles of lights are artfully hung in patterns dictated by Tiffany's head designer, while 1,800 more strands are draped on the lakeside willows. Join the Danes in warding off the cold with æbleskiver (iced doughnuts with black currant jam) and gløgg, a steaming hot mulled red wine laden with raisins, almonds, cinnamon sticks, and cloves—all of which are steeped in aquavit or schnapps. There's also a crafts market installed along a canal in the historic Nyhavn district; try to visit it between 5 and 6pm weekdays to catch the town crier.
Look For: Pixie-like nisser, tiny household elves that infest Denmark around Christmas clad in clogs, red shirts, and pointed red caps. More fickle than their cousin Santa, they might bring presents if you leave them bowls of porridge in the attic; if you forget, they'll visit all kinds of mischief instead.
