Highlights: Johannesburg Zoo is home to more than 3,000 species of mammals, birds and reptiles. The enclosure of lions, elephants, giraffes, and great apes is only divided by trenches and has no iron railings at all, so it is very popular with tourists. In addition, the newly designed polar bear habitat and the large bird cage where people can walk back and forth are also popular with tourists. In Midrand, Johannesburg, there is a Transvaal Snake Park, which displays a variety of African snakes, and the scenery is quite attractive.
