Primates are generally housed in the North West section of the zoo, in and surrounding Primate Panorama. Primate Panorama spreads over 7 acres (2.8 ha) and primarily houses apes and other larger primates. Tree-dwelling apes and monkeys live in open-air wire mesh tents that soar four stories high and cover more than an acre of ground. Inside these tents, the primates can play and climb on twisting vines. Gorillas roam freely, climbing ropes and taking afternoon hammock naps in one of the largest Gorilla habitats in the world. Orangutans have their own outdoor habitat where they can climb trees and swing in hammocks.
