Gunung leuser Orangutan Heritage Area


Guided wildlife walks


The karst forest in Batu Katak is the home of wildlife such as orangutan, tiger, sunbear, hornbill, slow lorys, many insects, reptiles and amphibians, and also amorphophalus titanium. It is a part of the last green buffer in the border of Gunung Leuser National Park in Bahorok District. The population of this area is a small community. This is the home of The Karo, or Karonese people, most of whom rely on local sustainable resources for their own livelihoods. There is a program for Ecotourism activities in the forest to see the wildlife and flowers. A local NGO focuses on nature conservation, education, habitat restoration and sustainable livelihood development.


We are an NGO focusing on protecting this area, working together with the local community and the National Park.
