Free things to do with kids in Seoul

Slides, rope climbing and swings over sand, with taps nearby to rinse off. The water-play pond is a short walk away.

A long walk beside a restored stream below street level, with herons and ducks to spot in the water.

A zoo, a carousel, gardens and an old-style playground in one big park, so it fills a whole day. The kids' museum is inside too.

Towering bookshelves inside the mall, with picture books and weekend kids' workshops, a step from the aquarium.
