Areas and attractions The Phoenix Zoo has four major themed areas, or "trails", where visitors can experience exhibits representing different areas of the world and their native wildlife: the Arizona Trail, the Africa Trail, the Tropics Trail, and the Discovery/Children's Trail. Arizona Trail The Arizona Trail is designed to emulate the wildlife and plant life of the state of Arizona. It features several plants native to the Sonoran Desert including the saguaro cactus, and animals such as the coyote, collared peccary (more commonly known as the javelina), cougar, bobcat, raven, turkey vulture, coati, thick billed parrot, Sonoran pronghorn, and the Mexican wolf. Africa Trail The Africa Trail showcases many of the most popular animals in the world, including the African painted dogs, hamadryas baboon, mandrill, ostrich, Mhorr's gazelle, white rhino, Grévy's zebras, lions, cheetahs, Reticulated and Masai giraffes. The Desert Lives (pronounced like "life") trail, diverts off of the Africa Trail before and after the lion and hyena exhibits, and features bighorn sheep and Arabian oryx among the natural buttes. Tropics Trail The Tropics Trail has two parts. The inner trail following the lake is home to the "Tropical Flights" aviary as well as Bornean orangutans and the common squirrel monkeys of "Monkey Village". The outer tropics trail passes by the Komodo dragons in the "Land of the Dragons" exhibit, Asian elephants, an Indian rhinoceros, a jaguar, Galápagos tortoises, Aldabra giant tortoises, iguanas, anteaters, Sumatran tigers of the "Isle of the Tiger" exhibit, and an assortment of tropical birds. It includes the Forest of Uco, a lush rainforest landscape that surrounds visitors along a 1-mile walking trail and includes reproductions of a South American mercado and a scientific expedition and ruins, and highlights several tropical animals including the Andean bear. Children's Trail The Children's Trail lets children get close to many small animals from around the world,
