Eco Treks

Sustainable Eco Treks

Join an eco trek and discover the hiddens fragmented forests around Landak River. 

Located just 4km from the main touristc area of Bukit Lawang and surrounded by the mountains of the Gunung Leuser National Park, it offers a different trekking experience. Be enticed by the clean, slow flowing river and mosaic of environments.


The agro-forests and fragmented forest patches are hidden within huge limestone rock formations, typical of a Karst forest. This unique environment, with geological features of  towering limestone rocks, cave systems and  streams create a diverse environment which is rich in biodiversity.

Explore these forests patches with us to help conserve the delicately balanced ecosystem.

Why are these forest patches important?

These extrordinary forest patches are hidden and have unique features which create an enviroment for diversity. The steep, often inaccessable limestone rocks have retained much of their tree cover, even though the surrounding areas have lost the large tree canopy.

A small population of wild sumatran orangutans live amongst these forest patches, along with several other animals: Thomas-leaf monkey (Presbytis thomasi), Long and Short-tailed Macaques, which can often be seen, and the less seen Silver leaf Monkey (Trachypithecus cristatus). There is evidence of porcupine, civet cats, wild pig, deer, leopard cat, and even slow loris. 


There are many species of birds, insects and butterflies. Inside the cave systems bats fly about. 


All the animals here are wild and behave naturally, so Eco-treks here are about sitting quietly, observing at a distance and enjoying the environment.

2 Day Eco-Trek

This is coming soon.

We are still in the process of finding new routes and training porters to cook in this new place

Please Note:

The orangutans that live in these forests and around this area are wild. They are generally used to the local people who take the rubber or fruits from their land, because the majority of the local people in this area ignore them. The orangutans are not fed by humans, but they do come onto local's land to feed on the wild fruits. 

Although we regularly check and monitor the area for Orangutans, it is not 100% that guests will see them. They are sometimes resting in the trees sitting on top of the rocks, so it hard to see them. However, if an orangutan is spotted then we ask guests to be quiet and not stand underneath where the orangutan is, as they are known to break branches and throw them to the floor. If guests watch and sit quietly, then the Orangutans do tend to settle.

Thank You :)

We look forward to taking you to explore and see the wild orangutans!!
