Responsible Trekking in Bukit Lawang

Bukit Lawang is a great place to start your jungle experience of the Gunung Leuser National Park. The trails are well established and it is reasonably easy to see ex-captive Orangutans lively freely, Thomas-leaf Monkeys, Macaque monkeys and other wildlife. Go deeper into the jungle to see wild orangutans, hornbills and other interesting wildlife.


The jungle is mountainous so involves uphill and downhill hikes. However, all our treks are suitable for anyone which is fit and healthy. 

We've highlighted our most popular jungle treks below.

Half day eco-trek, July 2017

I had a great experience at my very last day in Bukit Lawang! The guide is not feeding or calling the animal. The benefits: Wildlife stays wild and you can observe the natural behaviour of the animals.
