Hidden Forests at Landak River

Landak River is located just 4km South from the main touristic area of Bukit Lawang. There are just a couple of guesthouses nestled along the river, it is scarce of tourists and still tranquil.


The hidden forest at Batu Kelinici and Batu Kapal sit close to the clean and slow flowing Landak River and overlook the beautiful mountains of the Leuser National Park.  The area was once covered in virgin forest, but some areas were cleared of large canopy trees and other areas completely cleared for monoculture rubber and oil palm plantations, thus leaving fragmented areas of forests.


However, this does not mean that there is no wildlife. These secondary forests are hidden on and within huge rock formations. This area is a unique environment rich in biodiversity where wild Orangutans live along with many bird species, butterflies, insects, small mammals and other monkeys, such as the Silver leaf Monkey (Trachypithecus cristatus).  The land here is geologically interesting with towering limestone cliffs, rock formations, cave networks with dangling lianas and straggling fig roots. What a great place to explore!

Our Responsibility

It is peaceful, tranquil and allows for a real wild experience without any established trails. Because these forests are fragmented they are a delicately balanced ecosystem which we want to preserve. Treks here are eco-friendly and sustainable, using local people as guides. This gives them an income and an incentive to protect the area. 
We also only take between 2-3 people maximum on these eco-treks as we do not want to destroy the environment.
We offer a few trekking options to see this beautiful place including an over night stay in a local guesthouse or camping in the forest under the rocks. Want to combine natural beauty, nature with adventure.... then join our adventure trek. These treks are suitable for individuals and couples, and would suit anyone with reasonable fitness.
If your looking for something a little different from the classic treks in Bukit Lawang and want to contribute to conservation: then this is your place!

Why are these forest patches important?

These extraordinary forest patches are hidden and have unique features which create an environment for diversity. The steep, often inaccessible 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. The less seen, but often heard, 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.
