Great apes and other primates can be seen both indoors and outdoors in several locations at the Zoo. The Great Ape House is home to western lowland gorillas and orangutans.
The house is about mid-way on Olmsted Walk, between the Small Mammal House and the Reptile Discovery Center. Think Tank is home to Sulawesi macaques. See below for all the Zoo's exhibits where primates can be found.
The Great Ape House is home to six western lowland gorillas, who may be outside in the yard, inside the House, or in a private space in the House.
Depending on the time and the weather, the great apes may be inside or outside. They are usually inside the house after 2 p.m. From April to October, animals may be outside until 5 p.m.
If you prefer seeing the primates outdoors, the morning and mid-afternoon are better times. These animals tend to nap in the middle of the day. Also, there are likely to be fewer people inside the house in the early morning and late afternoon.
