Take only photographs, leave only footprints

Sumatra EcoVentures is unique as we not only offer responsible trekking in the Gunung Leuser National Park, but specialize in taking guests on eco-treks to less explored areas and forests. In doing this, we are revealing other enchanting vulnerable environments to our guests. Thus, helping to protect threatened areas of forests by working with local people and supporting local communities.

Jungle trekking in Bukit Lawang can be an amazing experience and people from all over the world come to view the many ex-captive Sumatran Orangutans in their natural habitat, but we are concerned about the impact this is having on the forest environment and the Orangutans. Our main focus is on sustainabiltity and eco-friendly pratices.

The well-walked trails are only a small section of the Gunung Leuser National Park (GLNP) which is reasonably well protected due to tourism. However, there are many places located not far from Bukit Lawang that also border the GLNP. These places are just as beautiful, rich in biodiversity and still untouched by mass tourism. The difference is these forests are not protected. These areas are vulnerable to deforestation, hunting and illegal activities.


By offering eco-trekking in these areas, we can use local people as guides who are extremely knowledgeable about their local area, along with our selected certified guides in Bukit Lawang.

 This also helps relieve the number of tourists entering the jungle in Bukit Lawang. Bringing guests to these other places helps supports the local community and gives the local people an incentive to not cut down the trees for mono-culture agriculture. We can then also work towards sustainable tourism in these areas.


10% of our jungle trekking profits goes towards projects in these areas or towards buying and planting trees.

Want to experience both? Then why not join our Combo 2 Day Discover Eco-Trek, which combines the classic jungle trek with trekking in a hidden forest with wild Orangutans

Responsible Treks from Bukit Lawang

The trails are well established and walked, but it is reasonably easy to see animals, such as ex-captive orangutans, thomas-leaf monkeys and macaque monkeys. Due to presence of humans, they have become habitated. The area is mountainous so involves some up and downhill hikes. During high season, the main trails in the jungle can be very busy and visitors are likely to see large groups watching just one orangutan. 

To minimise our impact in the jungle, we only take groups of 6. We do not use sungle-use packaging for lunch, we remove all our rubbish from the jungle and take away fruit peelings.

Eco - Treks from Landak River

Trek in the hidden fragmented forests near to Landak River in search of wild orangutans. With no established trails, explore the huge towering rocks formations and cave systems for a really wild experience. We only allow 3 guests or less during one trek as the wild orangutans are not used to large group presence and we want to restrict our impact. This area is scarce of tourists, peaceful and sits alongside the beautiful Landak River
