Burgers Zoo is absolutely an absolutely fantastic zoo with many intresting animals and enclosures. Their biggest features are the five "Ecodisplays": Bugers Bush, Burgers Desert, Burgers Ocean, Burgers Mangrove and Burgers Safari.
The Bush is en enourmous greenhouse filled with rainforest. As i far as i know, it's the biggest indoor rainforest in the world? Inside live many free ranging birds, reptiles, amphibians and insects, and in open enclosures around the forest you can se such animals as the aardvarks, oriental small-clawed otters, yacare caimans, manatees and capybaras. Exploring this rainforest alone can take all day, since you have to look closely to find a lot of the animals.
The Desert is an indoor replica of an area in the Arizona desert. Like the bush, many birds and reptiles live in here. The few mammals in here all have private enclosures. These include bobcats, bighorn sheep and skunks. It's a really unique expirience.
The Ocean consists of huge aquariums with animals from the coral reefs and even the deep seas. Just breathtaking
The Mangrove is the smallest ecodisplay, and the least impressive. It's just a small indoor exhibition with various small animals from the mangroves, such as kingfishers and mangrove monitors.
The Safari is the only outdoor ecodisplay. On a huge savannah lives giraffes, white rhinos, wildebeest, zebra and waterbucks together (maybe i forgot a species or two), and in two seperate enclosures you can see cheetahs and lions. I know that they also just opened a new savannah themed restaurant there.
In the "older" part of the zoo you can see such species as orang-utans, siamangs, warthogs, bongos, Sri Lankan leopards and tree procupines, as well as a large number of birds in the older aviaries and pheasentry. The two enclosures for chimpanzees and gorillas are some of the best i have seen for the animals, and the chimp-group is huge!
Burgers Zoo is my second-favourite zoo so far, only surpassed by Blijdorp Dierenpark (Rotterdam Zoo)
Here is a map taken from their website, though it isn't the best one i have seen (anybody got a better one?):
