Top 22 most popular water parks in the world

Aqualagon, France

Part of the impressive Villages Nature Paris eco-resort near Disneyland, this water park is heated entirely by geothermal energy and more than a third of its water purified naturally. Throw yourself down one of the eight giant slides, catch the surf in the wave pool or wallow in the lovely outdoor lagoons, which are heated to 30°C all year round. There's also an aquatic climbing wall, white-water rivers, geysers and a lovely spa.
