Valbyparken

A 20,000-square-meter nature playground full of play challenges built to get heart rates up.

A swimming hall built around water play, with a children's pool and slides.

Swimming in the harbor itself, at a bath among canals lined with new apartment blocks.

Staff run this fenced playground, with pedal cars to borrow, a zip line and a spider net, in a 1928 park with an Arne Jacobsen bandstand.

The old brewery's stables and its draft horses, and a basement full of bottles from all over the world.

In an old cotton-spinning mill under a ceiling hung with water-lily shapes, with Kids'n'Sushi sessions where children roll their own sushi.
