Eco - Treks

Our Eco-treks are sustainable and eco-friendly. Our Eco-treks support local people and help to protect the forest from deforestation.

Our Eco-treks start from Landak River which is located 4km South from the main touristic area of Bukit Lawang. The river is clean and slow flowing and borders the national park.
Landak river is lined with a mosaic of environments; rubber and oil palm plantations, agro-forests, agricultural land and forest patches. These forest patches are mostly hidden within and on huge limestone rock formations, typical of a Karst forest. Batu Kelinci (rabbit rock) is hidden behind the ridge of a rubber plantation. When you arrive, you are welcomed with towering and over-hanging rocks which have retained their forest.
Further along the river, sits Batu Kapal (ship rock).  Here, the rocks  are steep and mostly inaccessible but again still retains much of its forest and big trees.
Although these karst forest patches are fragmented, and many of the large canopy trees have been cleared between them, it does not mean that there is no wildlife. This unique environment, with towering rocks, cave systems and different water conditions create a diverse environment which is rich in biodiversity.
A small population of wild Orangutans live in this environment along with several monkey species; Thomas-leaf monkey, Long and Short-tailed macaque and the less seen Silver leaf Monkey (Trachypithecus cristatus). Many species of birds, insects and butterflies can be found and 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. 
These environments have their own temperature and generally free of mosquitoes! It is peaceful and allows for a real wild experience without any established trails like the jungle in Bukit Lawang. It is scarce of tourist and with a small population of wild orangutans, they can been seen in peace.
These forests are a delicately balanced ecosystem which we want to preserve. Our Eco-treks were formed to provide income for local people that live in the area by using them as guides. We also only take between 2-3 people maxium on these Eco-treks so not to disturb 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!!
