No. 24 De Efteling, Kaatsheuvel, Netherlands
Annual Visitors: 4,125,000
For its 60th anniversary, this fairy-tale-inspired theme park 50 miles south of Amsterdam has unveiled Aquanura, a fountains-and-light extravaganza that is Europe's third largest water show. The park itself opened back in 1952, three years before Disneyland in Anaheim, and remains nearly twice its size.
