Gunung-Leuser National Park
Gunung-Leuser National Park is a large national park covering 950,000 hectares in Northern Sumatra.
The easiest access is from the village of Bukit Lawang, situated at the eastern side of the park. In order to enter the park you need to buy a (reasonably priced) permit and be accompanied by a licenced guide, both can be arranged at Bukit Lawang.
There are many animals and birds in Gunung-Leuseur National Park including: orang-utans, white and black gibbons, thomas leaf monkeys, toucans, moon snakes and lizards. The park is also home to the Sumatran tiger and Sumatran rhinoceros, although it is very unlikely these will be seen.
Many visitors arrive wanting to see the orang-utans. A brilliant experience can be found at the orang-utan sanctuary, which is located at the edge of the park, a short walk from the vilage. Here, you can usually encounter semi-wild orang-utans at the feeding platform. Feeding usually happens twice a day.
However, a truly amazing life experience is to see orang-utans in the wild. To increase your chances, you should consider sleeping overnight in the park in order to get deeper into the Rainforest. You must trek wth an experienced guide.
