Unlike most of the 2008 Olympics venues, Běijīng’s National Aquatics Center, aka the Water Cube, has found a new lease of life post-Olympics. The otherworldly, bubble-like structure now houses Běijīng’s largest indoor water park. It's a fave with children, who can negotiate neon plastic slides, tunnels, water jets and pools, all set alongside elaborate, surreal underwater styling.

There’s a lazy river, a 40ft free-fall drop inside a plastic tube, and a wave pool designed to mimic the ocean. The park is about 7km north of the city centre.
