Budapest has an abundance of kids' establishments, ranging from "playhouses" for ages 2 to 10 — see eg this and this — to everybody's favorite Margitsziget with pony rides (ages 3 to adult) and go-cart and bobsled, adolescents' thrills (there is a long bobsled track at Visegrád in the scenic Danube bend). Check-out the newly renovated open air slide-park close to the Gellért Baths, on the Gellért Hill. (Look for "Gellérthegyi playground with slides" in Google.) Or the Challengeland at Csillebérc in the Buda Hills (for kids 5 and up). The Minipolis. Adolescents (and adults) usually enjoy the various "Escape rooms".

When walking downtown check out the playground at "Karolyi kert" or "Honved ter".

During the week there will be organized programs aimed at families with kids as well. Details will be posted once we have more data on families attending the reunion.
