Tanjung Puting is the largest and most diverse protected example of extensive coastal tropical heath and peat swamp forest in southern Borneo. The park is composed of 416,040 hectares and it is the only reserve in the world where Orang-utans can live protected in the wild.
The best way to enter the Tanjung Puting nature reserve is by taking a klotok Boat across the Sekonyer river from Pangkalan Bun port.
Orang-utans means 'person of the forest' in the Malay language. They are known as gardeners of the forest and play a vital role in seed dispersal and in maintaining the health of the forest.
They have proportionally long arms and short legs and their hair is reddish-brown. Adult males may develop distinctive cheek pads or flanges and make long calls that attract females and intimidate rivals
they travel by moving from one tree to another, and usually avoid climbing down to the ground.
