Semenggoh Nature Reserve is by far the biggest Orangutan Rehabilitation Centre in Sarawak. Back in 1975, it was established as a sanctuary for Orangutans who were injured, orphaned, or being held captive as illegal pets. Currently, the centre serves as a habitat for the Orangutans and also a place for visitors to learn about this endangered rare species. This wildlife centre has a thriving population of healthy adolescent and young adult semi-wild Orangutans. Semenggoh Nature Reserve is also a habitat for rare flora and fauna, including the giant squirrel, pigmy squirrel, gibbons, and a variety of birds, making the nature reserve an ideal place for nature lovers. Besides, visitors will also have an opportunity to interact with the orangutans as they will swing down from trees for a free hand out of fruits during feeding time from 09:00 to 10:00 & 15:00 to 16:00
