Sandakan is famous as the gateway for eco-tourism destinations in Sabah such as the Sepilok Orang Utan Sanctuary, the Turtle Islands Park, Sukau Proboscis Lodge, and the archaeological Gomantong Caves. It is also the notorious site of a World War II Japanese airfield. One of the main reasons for visiting Sandakan is to see the Orang Utans at Sepilok. The Sepilok Orang Utan Rehabilitation Centre was set up in 1964 to rehabilitate orphaned baby orang utan. Set in the lush 4,300-hectare Kabili-Sepilok Forest Reserve, the Centre under the administration of the Wildlife Department of Sabah attracts tourists and researchers alike, giving them the opportunity to watch the orang utan up close in their natural habitat.
