is a large, expansive African savanna setting just outside the indoor exhibit exit that primarily houses the zoo's giraffes. There is also a large yard for a family of African painted dogs, a hog yard that has been used by both common warthogs and currently red river hogs, and multiple yards for the zoo's black rhinos. While many of these animals cannot be viewed indoors, they have access to indoor habitats year-round. When the exhibit opened, it was also home to three African bush elephants, but they died, the last one dying at Hogle Zoo in 2005, sparking concerns about the exhibit. It later briefly held Bactrian camels, but it is currently an additional home for the zoo's rhinos. One noted resident of the exhibit was R1 (or Reptile One) the dwarf crocodile, who was seventy years old when he died in 2010, having lived within the zoo's Reptile House (now Park Place Café), the Regenstein Small Mammal-Reptile House, and finally, Regenstein African Journey throughout his life.

Fisher Great Ape House was closed and rebuilt with a new focus on the two African ape species, the chimpanzee and western lowland gorilla. The new center, opened in 2005, has over 29,000 square feet of indoor and outdoor living space for three ape troops, featuring dozens of trees, artificial vines, real and simulated bamboo, as well as skylights, waterfalls, moats, heated logs, and termite mounds for chimpanzees to illustrate their knowledge of tools to 'fish' for termites in their mounds. The exhibit has three spacious habitats – the 12,000-square-foot Kovler Gorilla Bamboo Forest, an open-air habitat with a moat around it, dedicated to the zoo's main gorilla troop. Two additional exhibits - the Strangler Fig Forest and Dry Riverbed Valley - each with mesh netting to secure the animals, can accommodate either chimpanzees or gorillas. Huge glass panels give guests nose-to-nose access with the zoo's apes both in the trees and on the ground. The exhibit also contains the Lester E. Fisher Center for the Study and Conservation of Apes, which encourages zoo guests to
