I loathe playgrounds in zoos, of course, and when I visit with my own children I will usually tell them that the play areas are infected with diseases, and thus need to be avoided. But this new development at Burgers seems rather stylish - confident architecture, tucked into the corner of the zoo, nicely done - and separate from the animals nearby (the wall in the foreground is that of the pygmy hippo and blue duiker enclosure).
