#1 Aqua Mundo (Bailly-Romainvilliers)
When Center Parcs and Disney team up with a renowned architect, the result is Aqua Mundo in Bailly-Romainvilliers, one of Europe's largest indoor water parks, located 32 kilometres east of Paris and less than 6 kilometres from Disneyland Paris. Water games, lagoons, a wave pool, paddling pools, and waterslides come together inside a giant origami-shaped complex. The outdoor areas are equally impressive, featuring numerous water attractions in pools heated year-round to 30 °C by geothermal energy.
