Set among a large swathe of coastal tropical heath and peat swamp forest, Tanjung Puting is one of the major hopes for the orangutan's survival.

Indonesia’s Tanjung Puting National Park is famed for its conservation efforts, and with the world’s largest population of wild orangutans, you can almost guarantee you’ll see some of these free-roaming great apes.

Visitors can spot an array of other native wildlife — including proboscis monkeys, civets, gibbons and sun bears — so jump aboard one of the many traditional Klotok boats sailing up the Sekonyer River, and keep your eyes peeled. Spend a day visiting the orangutan research and rehabilitation centre, Camp Leakey, for an unforgettable, up-close experience.
