The Kebun Binatang Ragunan (Zoo of Jakarta) has, at the center of the park, a 32 acres (13 ha) primate section called «*Schmutzer Primate Centre*». One of the most impressive exhibit of this area is the bornean orangutan exhibit. This 1.9 ha (4.7 acres !) exhibit is just a part of the tropical forest left natural, where primates have free access to the trees and lots of other natural elements to discover. More than 15 orangutans live here. Visitors can see them from different glass-fronted observatories.
