No matter what time of year you visit Copenhagen, something's always happening at Tivoli Gardens. Named after the Jardin de Tivoli in Paris, this park dates back to 1843. It includes roller coaster rides, a concert hall, and a theater. During Christmastime, visitors can go ice-skating on the lake or do some shopping at the market for local delicacies. In the evening, enjoy a nice dinner and late-night fireworks.
