There are two farms which childrens will love - Surrey Docks City Farm, accessible from Surrey Quays station - there's a pleasant walk traffic free walk down the right hand side of the shopping centre and along the edge of Greenland Dock to reach it.

and Hackney City Farm. Turn left out of Hoxton Station and walk along Dunloe St which is quite a quiet road. I was up there on Sunday. Large farm with scores of animals and a great cafe. Feeding time (for the animals!) around 4.30pm. If you want to extend your visit, walk north through Haggerston Park (Green Flag status) then along the tow path of the Regents Canal to Hoxton.
