This Zoo has plenty of variety, and many of the enclosures give views of unusual animals- both African indigenous and "exotic". The description plaques are quite informative, catering for many levels of age / own experience and knowledge base. As it is situated a bit "away" from down-town Jo'burg (in a suburb called Forest-town or Saxonwold, near Zoo Lake, approx. 5 clicks north of down-town JHB)), the press from locals trying to sell their wares, or to beg, is a little less than some other places, BUT this is "Africa", so you cannot hope to totally escape this issue, "anywhere". From time to time, local school children are bussed in on an education excursion, in which case you can expect some additional levels of noise and rowdy-ness as you amble (and they tend to rush) around the facility- but probably not much worse than in any other lesser-developed regions. Probably better to plan a trip in the mornings, particularly in the summer months, to avoid afternoon thundershowers curtailing the excursion. A contra to this issue is that certain of the carnivors have set feeding times (some perhaps a bit later in the day??), which are a great sight to watch!!... check the web-site for details 9as they always say).
