Orangutan Valley consists of indoor part and outdoor part. The indoor part is spacious and bright, with imitate mountains and forest as background. There are ropes, rubber tires, parallel bars, horizontal bars, balance beams, slides for orangutans to climb at and play with. The outdoor part is like a small but spacious green island covered with grass. There are climbing frames, wood piles and tire rings connected together with ropes. Orangutans can climb along the ropes and have a good time playing “in the air” without the trouble of touching on the ground.
