No. 25 Tivoli Gardens, Copenhagen
Annual Visitors: 3,963,000
Danes were visiting this historic amusement park a full century before Walt Disney's vision of his SoCal utopia had blossomed. Open just six months each year, Tivoli still managed to slide into the world's top 25 for 2011. The most heart-pounding attraction is Vertigo, a flight simulator that launches passengers in the air at 60 mph.
