Hampstean Heath South End Playground
This must be one of the nicest playgrounds in London. Located on the South end of Hampstead Heath, just below Parliament Hill, this is a modern complete area for kids of all ages. In the warmer months there is also a Paddling Pool.
Of course this also means that this place is often crowded, but it is big enough to handle the melee and action of tons of kids and exhausted looking parents.
Nonetheless, top spot to hit with kids and also it is in the Heath, so many options on walks to/from this area.
