#1 Aqua Mundo (Bailly-Romainvilliers)
When Center Parcs and Disney collaborate with a renowned architect, the result is Aqua Mundo in Bailly-Romainvilliers. This massive indoor water park is located 32 kilometers east of Paris and under 6 kilometers from Disneyland Paris. It features water games, lagoons, a wave pool, activity basins, and endless slides. The complex mimics a giant origami structure, complete with scenic ornamental terraces. Outside, the heated geothermal pools stay at 30 degrees Celsius (86 degrees Fahrenheit) year-round.
